Pacific Research Solutions RI-300e User Manual

SECTION 1 INTRODUCTION

What is the RI-300(e) Version

The RI-300e and RI-310e are revised versions of the RI-300 and RI-310. The RI-300e has some enhanced performance
features, including a battery backed real time clock (RTC). This manual will cover both controllers. Areas where there are
differences between the controllers will be clearly pointed out. However, when this manual talks about the controller as
“RI-300” or “RI-310” it is also including the “e” version.

Overview

Your controller represents the latest technological advances in repeater control systems. The RI-300 utilizes a microprocessor
design, which provides all the control functions for a single repeater on two printed circuit boards, each 3½ by 6 inches. One
board provides all audio processing and the second board provides for digital processing. With this two-board design, the
digital data is isolated from the audio to produce superior audio quality. The RI-300 does not require memory backup batteries;
all program configurations are stored in a NON-VOLATILE EEPROM (Electrically Erasable Programmable Read Only
Memory), which maintains its data even with the power disconnected. This EEPROM may be re-programmed by the user in
order to change the system characteristics. A “WATCHDOG TIMER” and “POWER SUPPLY SUPERVISORY CIRCUIT”
constantly monitor the microprocessor and power supply, maintaining the operational integrity of the system.
The RI-300 is easy to set up and use. Only five interconnect wires are required to interface to your repeater. With three simple
audio level adjustments, your repeater will be operational with the default user commands. The telephone is connected with the
provided RJ-11 telephone jack.

Once you are familiar with the macro command system, you can customize your user commands, messages, and schedulers.
We recommend that you read sections 1 through 3, 8 and 9 of this manual first, to get familiar with the system and its basic
operation. The other sections of this manual provide a more thorough explanation of the RI-300's many features.

Feature List

The following features of the RI-300 repeater interconnect are not available together in any other repeater controller in the
industry:

• On board CTCSS and DCS decoder and encoder. You do not have to add an external decoder. The decoder and encoder

are remotely programmable. Multiple CTCSS and DCS tone panel features are provided.

• Full duplex telephone interface with a self-balancing hybrid.

• Speech synthesizer. Read back system configuration and create your own speech messages. Includes a 661-word

vocabulary and 32 command words (example Time, Temperature, etc.).

• Optional digital voice recorder. Create your own messages or station identification in your own voice.

• Flash program memory. You can make firmware updates without changing any components.

• Local microphone and speaker connections.

• Auxiliary audio buss. Connect as many as 8 controllers for links, remotes and multiple repeater connections.

• The Transmit audio level, squelch level, tone generator level, CTCSS level, DCS level and telephone level potentiometer

adjustments may be remotely adjusted by radio.

• On board squelch circuit. You do not have to add someone else’s circuit. This is SmartSquelch, an intelligent

microprocessor-controlled squelch already installed on board, and it’s fast.

• A selectable sub audio reject filter is provided to remove the received CTCSS sub-audio tone from being repeated.

• DTMF tones may be passed, muted, or regenerated.

• Dual tone generator with level and frequency control is available.

• In-band freq uency counter.

• Temperature sensor input

• Analog input for S-Meter or other analog devices.

• User programmable inputs and outputs.

• User programmable event scheduler. Commands can be programmed to execute automatically at user-selected times.

• Built-in receiver audio level meter. You do not need a voltmeter or scope to set up the receiver audio level.

• NON-VOLATILE EEPROM data storage. You never have to be concerned with replacement of the memory backup

battery.

• User command macro editor. All user commands are completely programmable.

• All the repeater owner has to do is interface the repeater audio and remotely program the functions and features desired.

Pacific Research Solutions RI-300e User Manual
The RI-300 provides excellent audio quality. With proper consideration when interfacing the controller to the receiver and

transmitter, your repeater will provide excellent audio to the users. Interfacing information is provided in numerous sections of
this manual and support is available from the factory. The receiver discriminator output must be connected to the RI-300 audio
input in order for the squelch circuit to function prope rly and to p rovide excellent audio. Do not connect the RI-300 audio
input to the receiver speaker connection, as the squelch will not operate properly. The RI-300 provides for easy
programming of customized user features or user commands by giving you the ability to write and name simple macros. All
messages and telemetry are also programmable.

What is an RI-310?

The RI-310 is one model in a series of RI-300 repeater controllers designed specifically as a “Plug-N-Play” component for the
Yaesu/Vertex VXR-5000 repeaters. This manual was written around the RI-300 repeater controller, which is a generic version
that is designed to interface with any repeater. The RI-310 has some additional features that allow you to remotely control the
frequency and transmit power level of the repeater.

SECTION 2 QUICK START

This section will cover the basics of installation and programming of your RI-300. You may also need to review section 4 or 5
for more details on connecting your RI-300 to your repeater. Once you have covered these basics, we recommend that you
thoroughly review the complete manual in order to get the most out of your controller.

UNPACKING THE RI-300

Inspect the carton for the following contents and if any of the items that you have ordered are missing or damaged, notify your
RI-300 dealer or the factory that shipped the unit to you.

1. RI-300 Repeater controller board with mating DB15S connector. RI-310 does not come with the DB15S connector.

2. UM-300 Printed user manual.

3. Optional accessories that may be included with your RI-300.

MOUNTING THE RI-300 REPEATER CONTROLLER

Skip to section 5 if you are installing a RI-310

1. An optional single controller desktop chassis or a standard 19-inch wide 1-3/4 inch high rack mounted enclosure is
available. Mounting holes are provided for the repeater controller boards within the enclosure.

2. The repeater builder can mount the RI-300 repeater controller in any enclosure of his choice. The enclosure that you select
should be strong enough to mechanica lly protect the contents. The enclosure should be made o f metal with good shielding
properties. We do not recommend the use of a plastic enclosure in a RF environment. Mount the RI-300 unit with #4-40
standoffs on the mounting surface.

3. Avoid installing the RI-300 in the following places:

• Directly above a transmitter or power amplifier because of heat and RF considerations.

• Directly above any power supplies because of heat and 60 Hz coupling into the audio circuits.

INTERFACE YOUR RECEIVER and
TRANSMITTER

The RI-300 repeater controller is very easy to interface with
your repeater . Before you co ntinue, you need to make the
following connections. All connections are covered with greater
details in section 4 of this manual. If you are installing the RI­310, you should go directly to section 5.

1. +12 Volts DC power source, J1 Pin 1.

2. DC power ground, J1 Pin 9

3. Receiver Discriminator audio, J1 Pin 2.

4. Audio return and/or shield, J1 Pin 10.

5. Transmitter audio, J1 Pin3

6. Transmitter DCS audio (if required), J1 Pin 11.

7. Transmitter keying circuit (PTT) active low, J1 Pin 4 .

SETTING AUDIO LEVELS

Adjusting the levels in your controller is very important, in order to achieve proper decoder operatio n and avoid clipping and
distortion. See section 7 of this manual for more complete details on correct adjustment of the audio levels.

Receiver Gain

1. Setting the receiver input gain maybe the most important adjustment in the controller.

2. Transmit a carrier on the repeater’s input channel.

3. Generate a 1000 Hz tone at 1.5 kHz of deviation on the repeater input.

4. While you are sending your test tone, press and hold the button labeled “INIT”. The system LEDs will operate as a level
meter, the first LEDs through “AUX” will indicate 1.5 kHz of deviation.

5. The receiver input level is adjusted by the multi turn pot VR1 labeled “RCVR” located right of the radio interface
connector.

Squelch Level

The RI-300 uses a digital potentiometer for the squelch level setting. Unlock the controller and use S-Command 50 to set the
squelch potentiometer to specific steps or allow up and down control of the potentiometer. You can also use the programming
software to adjust this potentiometer. Set the squelch level until the COS LED goes out, and then add about 4 to 5 counts to the
setting.

Transmitter Level

The best method is to use a service monitor to measure the transmitter deviation. If a service monitor is not available, use any
receiver that can be easily flipped back and forth between the repeater input and output channel while listening to the levels.
Ideally, you will have the same transmit deviation going out of the repeater transmitter as coming in the receiver. Transmit a
3kHz deviation tone on the repeater input channel. As you flip back and forth between the repeater input and output
frequencies, then by listening, adjust the repeater transmitter audio level or deviation. This level is remotely adjusted with a
digital pot, S-Command 12. You can also use the programming software to set the transmitter level potentiometer.

OPERATION

Once you have connected your controller to a receiver / transmitter and adjusted the audio, you should then confirm its basic
repeater operation. This can be done by transmitting a carrier in the input of the repeater and observing the “COS” LED
turning on and off when you key and un-key. You should next see the “PTT” LED turn on while the repeater transmitter is on.
Next, you can confirm the repeater audio path by listening to your self on the output of the repeater. Finally, if you transmit a
carrier with a 100Hz CTCSS tone on the input of the repeater, you should see the “RPT-TSQ” LED go on and some other
LED’s flashing. The flashing LEDs will be described later in this section. See section 8 of this manual for more details on the
controller’s operation and default user commands.

INITIAL SETTINGS

You are now ready to set the Station ID and Tone Squelch (CTCSS) decode. This subject is not easily covered in a single
paragraph. Therefore, we recommend that you go to section 9 of this user manual for this procedure.

SECTION 3 PROGRAMMING SOFTWARE

An optional programming software and cable package is available. This software is designed to run in Windows 95/98, ME,
NT, 2000 and XP. The software will allow you to read, change and save all parameters within your RI-300 controller. You can
even load controller firmware update (FLASH) to the controller over the programming port. For software installation, follow
the instructions included with the software disk. The supplied programming cable is a special cable and has interface
electronics built in. Do not try to build your own cable. You can plug this cable into the controller at any time with or without
the controller powered on. Use the connector labeled “MIC/PROG”. Do not try to plug this cable into the connecto r labeled
“TELCO”. The end of the cable with the D-Sub connector, plugs directly into your computer’s COMM port. Make sure the
power to the repeater and controller is turned on. The auxiliary buss will be disabled during the data transfer process when you
are sending or receiving data using the programming software.

You may us the Pacific Research ProgramLink or the Vertex VX-VLP-1 cable with the programming software to program you
controller.

INSTALLATION

1. Install this program in a Windows 95, 98, ME, NT, 2000 and XP based environment.

2. From your floppy disk or CD ROM, run the setup program.

3. Follow the instructions from the setup program.

4. You can now click the RI-300 icon to start the programming software.

OPERATION

1. After you have installed your repeater controller, attach the programming cable to the programming port on the controller.
Connect the other end of the cable to your PC serial communication port.

2. Start the programming software.

3. Select the "Serial Comm. Port" you are using.

4. You should notice that the "Active Controller" LED is lit. This means that the programming software is communicating
with your controller. You may select an active controller for viewing or communicating at any time. Do this by clicking
on an active controller LED or via the “View Controller” combo list. If none of the Active Controller LEDs show
indication of a controller, check your Comm. Port number and the programming cable.

5. Before you send any data to your controller the first time, you need to make a template of your controller.

6. Go to "Controller" and "Get data from…" pick the "Start Button". This uplo ad process will take about 90 seconds. You
should notice the progress bar moving during this process.

7. Once this process is complete, select "File" and "Save As". Select the file or type "RI300.rdf", this is the startup template
file. When the program asks if you want to replace this file, pick yes.

8. Each time you start the programming software, the program will automatically load and start with the RI300.rdf file. Now
each time you start the programming software, it will start with the defaults from your controller.

9. At any time, you can save your working data to a ne w file name.

When making changes to your controllers data, it is good practice to save the repeater data file (rdf) with a dash number each
time you make a change. This way, you can return to an older file that you know works if you make an error in your c urrent
file.

FLASHING the CONTROLLER’S PROGRAM

As new features are added and revisions are made to the RI-300e, program updates are made available on our web site
www.pacres. com. Yo u can locat e these changes under the RI-300e firmware and software page. Do not attempt to flash a
RI-300e controller with RI-300 version 1.xx or 2.xx firmware. Only flash using version 3.00 or higher. With the same note, do
not attempt to flash a RI-300 controller with a version 3 or higher. Download these files from the web site and follow the install
instructions. It is important to closely follow the instructions as you may otherwise damage your current installation. Once you
have down loaded these updates, use the following procedure to flash the controllers program memory.

1. Connect your computer to the controller using the programming cable. Run the RI-300 Programming.

2. In the programming software, pick “Controller” then pick “Flash Program”.

3. In the file list, select the new flash file you want to send to the controller. The last three digits of the file name indicate the
file version.

4. Pick the “Open” button then the “Start” button. The flash process is automatic and will take 90 to 120 seconds to
complete.

PROGRAMMING SOFTWARE MENU

The basic startup window contains the status items shown. Use the "View Controller" or pick the “Active Controller” light to
select which controller on the auxiliary buss you want to monitor. Whenever you leave the cursor on a window item, the
program will show a hint as to the associated System Command that is adjusted by that item. The following is a quick overview
of menus and their functions.

Main Window

The main window shows the current activity of a selected
controller on the buss. The “Active Controller” group
displays all active controllers attached to the auxiliary
buss. The “Controller x Status” group shows the status of
the selected controller. The “Auxiliary Buss” group
shows the auxiliary buss status of the selected controller.
All System Commands sent over the auxiliary buss are
also logged within this group. The “RX Deviation” group
is used to set up the controller’s receivers input level.
This gauge is only active when you press the “INIT”
button on the controller after the power is turned on. The
“DTMF Decode String” shows and records the last 50
user and system commands. Each command has a date
and time stamp with the tone squelch that was used during
the command. The “Macro Error Log” will display errors
in macros as reported from the controller. If an error is
encountered when the controller executes a macro, the
controller will report the location of the error to the
programming software. You can select an error and pick
the “Show Me” button to see the location of the error in
your rdf file.

F

ile

Used to both save and open repeater data files (rdf). The programming software uses the RI300.rdf file as a template file. Any
changes you make to this file will be recalled each time that you run the program. Report printing is also available from this
menu. In the report printing, you can select various items that you want to print. If you select all items for printing on a factory
default set up, up to a 20 page report will be generated.

You can use the “Project Manager” to set up multiple files for applications
where you have multiple controllers connected to the auxiliary buss. In this
window, you select each rdf file for each controller that will be included in the
system. In the future, you can open this System Project File (spf) and the
software will load all rdf files used in you system. You can now select which
rdf file you want to edit using the “View Controller” or “Active Controller”
method.

MODEM INTERFACE

You should be able to use about any external modem that operates at 9600 baud or higher, can auto answer and operate in a
dumb terminal mode. In this application, we used a US Robotics external modem to connect to the controller. On the back of
the USR modem, you will find a configuration dipswitch. Set all of the dipswitches in the up position, except for switch 4,
which will be down. When using other modems, consider the following settings:

• Data Terminal Ready (DTR) - normal

• Suppress result code

• No echo, off line commands (Echo Off)

• Auto answer on first ring or higher, depending on shared telephone line

• Carrier detect - normal

• Dumb terminal mode,

disable command recognition

For people who want to share the telephone line between the modem and the controller, we have three different methods
available:

1.

Ring Delay:

With this method, you connect the telephone line to the modem and then connect the phone jack output from
the modem to the controller. Set up the modem to answer on 2 more rings then the controller. Example: set the controller
to answer after 2 rings and set the modem to answer after 4 rings. Then create a user command that sets S-Command 71 to
mode 0, disabling incoming calls. When you want to establish a connection with the controller’s modem, execute the user
command and then call the modem, the controller will not answer the call. Once you are finished or during the modem
connection, reset the incoming call mode to 2 or higher. Now, the controller will answer calls before the modem answers.

2.

Call switch box:

This method uses a modem/voice switch box. This is a box that into which the telephone line plugs. The
box modem port is connected to the modem and the box voice telephone port is connected to the controller. When a call
comes in, the box will direct the call to the modem or controller.

3.

Power control:

With this method, you connect the telephone line to the modem and then connect the phone jack output to
the controller. Connect a relay so that it will switch the power supply line of the modem. Use one of the controller’s
digital outputs to control the relay. Create two user commands to turn the relay on and off. Set the modem to answer on
the first ring and the controller to answer on 2 or more rings. When you want to call the modem, execute the user
command to power the modem and then call the modem. Once you are finished, send the user command to power down
the modem. Now the controller will answer the calls and the modem will not.

Vertex Programming Cable to Modem Cable

If you are using the PL-3 ProgramLink, you can use a standard modem cable to connect your modem to the PL-3. If you are
using the Vertex programming cable, you need to build a modem-to-modem cable because the Vertex cable works in the same
manner as a modem. The following schematic shows how to build a modem-to-modem cable for a modem equipped with DB­25 connector or DB-09 connector.

PROPER TECHNIQUES FOR QUALITY REPEATER AUDIO

Obtaining good audio in any repeater is based on understanding the design of the equipment. The audio in all frequency
modulation (FM) transmitters or phase modulation (PM) transmitters has what is known as audio pre-emphasis. Pre-emphasis
means that with increasing audio frequency the amount of the modulation will increase. The reverse is performed in all FM
receivers and is called de-emphasis. The RI-300 was designed to operate with flat audio response from the repeater receiver
and transmitter. This means that neither de-emphasis nor pre-emphasis of the audio is performed on the repeat audio path. This
leaves all of the emphasis filtering in the user's radio. The RI-300 controller does include a low pass filter that rolls off the very
high audio frequency content to prevent adjacent channel splatter. The ideal interface between the RI-300 and a FM modulator
is one in which a varactor diode is directly driven. However, the RI-300 does have a de-emphasis filter that can be turned on
for those applications where you may need to interface to a modulator with pre-emphasis. It is not advisable to drive the
microphone input on the transmitters. Most transmitters have significant audio shaping, compensating for the microphone
response and other characteristics. The input connections to the RI-300 must be connected directly to the receiver’s
discriminator for the squelch to work properly. On some receivers, this connection can be made to the squelch circuit input.

Page 11

Pacific Research Solutions RI-300e User Manual
Besides audio frequency response, you should consider the audio amplitude levels to and from the controller. If the levels to

and from the repeater are small, it may be valuable to use shielded cable. We recommend shielded cables at all times. Use
large signal levels whenever possib l e. On the other hand, do not let the audio signal get large enough where clippi ng occurs in
any stage of the controller, the receiver, or the transmitter. The RI-300 repeater controller has a built in audio level meter for
setting the RX input level. See section 7 for more details on adjusting the audio levels in the controller. Consider and pr actice
the above and you will have repeater audio that you and your repeater users will be proud of.

POWER SUPPLY CONNECTIONS (Pins 1 and 9)

The RI-300 operates on 12 volts DC nominal. The DC source voltage must be between 10 and 15 VDC. The controller
typically draws 140 ma. without the status LEDs turned on. Connect the +12v to J1 pin 1. Connect J1 pin 9 to ground or the 12
V return side of the power supply. The repeater builder may elect to incorporate an on/off power switch on the +DC side.
Most repeater owners switch the AC primary side of the power supply.

power supply must be over-current protected

installation. A ½ amp fuse is best. When connected properly, the green LED on the status LED display will light when the
power is applied and the system enable command is on.

. Use of a one-ampere fuse should be the largest capacity considered in your

The RI-300 repeater controller connection to the

REPEATER RECEIVER AUDIO CONNECTION (Pin 2)

Since the RI-300 controller has the squelch (COR/COS) circuit incorporated on board, the audio input
directly to the receiver discriminator output. Connect the receiver discriminator audio to the RI-300 J1 pin 2 and the receiver
ground or audio return to J1 pin 10. Do
get assistance from someone knowledgeable on the subject or contact our factory for support. If your discriminator does not
have adequate filtering for 455 kHz, you will have to provide for this filtering between the radio and controller. A 10mH
inductor in line with a 1000pF capacitor to ground should work. You may need to adjust these values according to the output
impedance of your discriminator. For best performance all audio connections should be made with a shielded cable. The
controller’s aud i o path has a flat fre quency response from 30 Hz through 4500 Hz except for the CTCSS high pass filter that
cuts off at 300 Hz. When interfaced properly to the repeater receiver and transmitter, the controller will provide superb audio
characteristics.

REPEATER TRANSMITTER AUDIO CONNECTIONS (Pin 3)

Use a direct FM type modulator whenever possible. The RI-300 does have a de-emphasis filter that can be turned on for those
applications in which you need to interface to a modulator with pre-emphasis. It is not advisable to drive the microphone input
on the transmitters. Most microphone inputs have significant audio shaping, compensating for the microphone response and
other characteristics. Always use a shielded cable. Connect the controller transmit audio output J1 pin 3 to the input of the
modulator. Connect the modulator ground or audio return to J1 pin 10. If a FM modulator without pre-emphasis is not
available, the RI-300 can be jumped to drive a phase modulator or modulator with pre-emphasis. Do this by installing jumpers
on JP5 pins 1-2 and JP1 pins 1-2. For FM modulation, install a jumper on JP5 pins 2-3 and no jumper on JP1. See section 17
for more information on this subject.

REPEATER TRANSMITTER PTT OR TRANSMIT KEYING CONNECTION (Pin 4)

The RI-300 repeater controller keys the transmitter at the required times.
controller will key the transmitter at times you may not think of, such as when the ID is due. It never fails when you disconnect
the antenna to connect an in-line wattmeter, the ID goes off or a repeater user arrives on the receiver input. Therefore,
disconnect power to the repeater and controller before performing these operations. The controller PTT keying transistor sinks
current, that is, the transistor pulls to ground the relay or keying stage in the repeater transmitter. This is by far the most
common interface. Should you need to source a voltage to PTT then contact Pacific Research Solutions for application notes.
The keying transistor can sink or pull down (active low) a maximum of 120 ma of current. Connect J1 pin 4 to the repeater
transmitter PTT.

WARNING

- As with all repeater controllers, this

DCS MODULATION (Pin 11)

Some transmitters will not accept DCS modulation with the voice audio. In these applications, the RI-300 will output the DCS
modulation on this pin so that it can be directly connected to the DCS input on your transmitter. Please review section 7 for
additional information on this subject.

Pacific Research Solutions RI-300e User Manual

DIGITAL INPUTS (Pins 6, 7 and 8)

The RI-300 has three digital inputs on board and is currently expandable up to ten, that can be used to trigger macros. These
inputs are C-MOS gates with a voltage swing of 0 to 5 VDC, TTL level. All digital inputs have a 10K ohm pull up resistors.
Your application must “pull down” or sink current with either a transistor or TTL gate or equivalent. Upon detecting either a
rising or falling edge or change in the state of an input, the controller automatically executes a macro. See Section 12,
S-Command 45 and 46 for additional information on programming these inputs. These inputs are located on J1 pins 6, 7 and 8.
See the connector diagram on the previous page. Depending on the squelch mode, S-Command 51, input bit 1 can be used as
an external squelch input.

DIGITAL OUTPUTS (Pins 13, 14 and 15)

The RI-300 has three digital outputs on board and is currently expandable upto ten, whose states can be modified by
S-Commands. Each of the three outputs can be individually commanded or forced into the high or low logic state or pulsed
high for a desired duration of time. These outputs are open collector NPN transistors and can sink up to 120ma each. Each
output has a 10K pull up resistor to 5 vo lts and can source enough current to drive a TTL or CMOS ga te. However these
outputs can sink current from a voltage sources as high as 24 volts. Using S-Commands (or macros that are composed of S­Commands), each output may be turned on or off or pulsed with the desired S-Commands. See Sections 12 S-Command 46 and
47 for additional information on programming these outputs. These outputs are located on J1 pins 13, 14 and 15. See the
connector diagram on the previous page.

ANALOG INPUTS (Pin 5)

The RI-300 has one analog input that can be directly read as a voltage in the range of 0 to 3.75 volts. This input can also be
connected to your radio's limiter output for a Signal Meter function. In some S-Meter applications, you may need to provide a
method for scaling the voltage connected to this input. When reading this signal over the air, use speech control word 014 for
the analog voltage and speech control word 013 for S-Meter.

DCS DECODE AND ENCODE SET UP AND OPERATION

With DCS (Digital Coded Squelch) decode and encode, you can also select any combination of DCS codes to operate your
repeater. You have 104 standard DCS codes that can be used for decode or encode. The decode codes are selected with
S-Command 20. The encode codes are selected with S-Command 21 and 22. Both CTCSS and DCS will operate together.
The system set up for DCS is the same as CTCSS.

Depending on your repeater, you may have to change the p olarity of the DCS TX/RX d ata. Once you have confirmed tha t your
radio audio frequency response is correct, you can enable a DCS code for the repeater decode (S-Command 20). When you
send that code to the repeater, check if the CTCSS/DCS LED goes on. If the controller does not decode DCS data, change the
RX polarity (S-Command 25). If your radio will not decode the DCS data from the repeater, change the TX polarity (S­Command 25). You can also use the programming software to view the current DCS decode to verify the data polarity.

The DCS encode level is remotely adjusted with a digital pot in the same manner as the squelch, except with S-Command 24.
The DCS encoder audio can be mixed with the voice audio or routed directly to the transmitter modulator via J1 pin 11. As
some modulators require a separate input for DCS audio.

CTCSS (Continuous Tone Coded Squelch System) uses continuous tones below 300 Hz. A single tone is assigned for a group
of users. When the tone has been decoded by the repeater, the repeater will pass the users audio. Sometimes two tones next to
each other can become confused with each other. In contrast, DCS uses digital data or code words. Each code word is unique
and all code words may be used on the same channel without interference. At the end of the repeater transmission and 1/2
second before the transmitter un-keys, the controller will encode a 134 Hz tone that serves as a turn off code. For correct
operation, the DCS data should have a FM deviation of 500 to 800 Hz.

Your transmitter and receiver waveforms should closely
resemble the waveform diagram, figure 1. If this is the
condition, then the low frequency response of your
repeater should be adequate. If your waveform resembles
figure 2, your modulator or discriminator does not have
enough low frequency response. Figure 2 was crea t ed
with a high pass filter with a corner frequency at about 5
Hz. Even with a cutoff this low, the filter strips vital data
from the digital code word.

Page 13

Pacific Research Solutions RI-300e User Manual
Because DCS may have extended periods of all ones and zeros, almost all components in the transmitter and receiver chain

must be coupled down to at least 2 Hz or lower. This requirement means that certain transmitters and receivers must be
modified before they are capable of DCS operation. Phase modulators, in particular, need special consideration because they
theoretically are incapable of being directly modulated by DC, unlike direct FM modulation methods. Low frequency response
is the primary requirement for DCS systems.

Unlike CTCSS, DCS the signal spectrum occupies considerable more bandwidth. A poor low frequency response in the
transmitter or receiver may not seriously distort a single frequency tone signal but may seriously degrade a wide band signal
containing multiple frequency components. The distortion risk is especially high if the frequency response delays the wide
band frequency components.

The RI-300 does include data error correction. But if too many errors occur, you may experience some blocking out of the
decoder. Errors can occur because of unwanted low frequency energy. The DCS decoders can be affected by voice energy that
falls below 300 Hz. Some radios do not remove this energy before transmission and can cause voice blocking of the decoder.
The RI-300 has a sub audio filter that removes this low frequency energy before the audio is re-transmitted. This feature will
increase the performance of the receiving radios. You may need to confirm that the radios used to operate the repeater, have
some type of sub audio filtering.

You will find that it is extremely important for the receiver and transmitter to be on frequency to achieve maximum
performance of the DCS function. Errors in the transmitter and receiver frequencies show up at the discriminator output as a
step function. Because of the long time constant required for the low frequency response, a step function can block the decoder
momentarily.

Before you start modifying your radio to operate DCS, make sure your service monitor is DCS capable. Some older monitors
require modifications to obtain the low frequency audio response needed for DCS operation. If in doubt, contact the
manufacturer.

Because there are so many radios that may need modification for DCS operation, we may not be familiar with your radio. For
this reason, we may not be able to provide technical support for some radio modifications. We want to hear constructive and
useful feedback. We appreciate having details about your successful modification of a radio for DCS operation.

SECTION 5 INSTALLATION (RI-310)

After unpacking and inspecting your RI-310 repeater controller, use the following steps to install the controller into the Vertex
VXR-5000 repeater.

1.  Before starting, locate the serial number of your controller on the backside of the PC Board. It is important to make

note of this number in a safe place. This number can be used with S-Command 58 or 59 to remotely reset or re­initialize the program.

2.  Start by removing the four screws holding the top cover on the Vertex repeater.

3.  Position the repeater with the antenna connector toward you and the heat sink to your right. The receiver unit is the

box closest to the “RX ANT” connector. The transmit unit is the box on the other left side far end of the chassis.

4.  The RI-310 controller will replace the Vertex controller. Completely disconnect all cables going to the Vertex

controller. You may need to remove the Vertex controller from the chassis to get at some of the cables. When you are
finished with installing the RI-310 controller, you may leave the Vertex controller mounted in the rack, as there is
enough room for both controllers .

5.  You will find some cables routed on the right side going toward the “ACC” and “LINE” connectors. Remove the

cable tie wraps from these cables.

6.  In this bundle of cables, you will find a 13-conductor cable. Re-route this cable past the left side of the receiver.

7.  You will not be using the "LINE" connector cables on the right side of the receiver unit. You can pull these cables

back to the “LINE” connector. We will also not be using the 12-conductor cable that is routed on the left side of the
receiver unit. You can also pull this cable back, bundle and tie these cables together and stow them.

8.  Locate the 6-conductor LED cable. This cable has multi-colored wire. Plug this cable into the connector (J1013) on

the bottom of the RI-310 interface board. This cable has 6 conductors but the connector housing has 7 positions.

9.  Find the 5-conductor cable that comes from the power supply unit. This cable has two red wires, two black wires, one

white wire and a 6-pin housing. Plug this cable into the connector (J1004) on the bottom of the RI-310 interface
board.

10.  Place the RI-310 in the slot between the receiver and the vertex controller. The MIC/PROG jack should be located on

the side closest to the power supply or RF power amp.

11.  The mounting holes in the RI-310 should line up with the mounting tabs in the Vertex repeater. The RI-310 is held in

place by the two screws that are supplied. The bottom of the RI-310 circuit board should line up with a card edge
bracket in the bottom of the Vertex repeater.

12.  Locate two cables that exit the right side of the transmitter unit. Plug the 8-conductor cable with one yellow wire into

the RI-310 controller connector labeled “TX-UNIT”. Then plug the 4-conductor cable with one shielded gray wire
into the RI-310 connector labeled “TX-MOD”.

13.  You should find one last 5-conductor cable with one black wire on the right side of the transmit unit. Plug this cable

into the RI-310 connector labeled “REG-UNIT”.

14.  From the left side of the receiver unit, you will find two cables. Locate the 10-conductor cable with one violet wire

and plug this cable into the RI-310 connector labeled “RX-UNIT”. Then plug the 2-conductor shielded cable into the
RI-310 connector labeled “RX-DET”.

15.  Last, from the left side of the receiver unit, you will find a 13-conductor cable with one green wire coming from the

“ACC” connector. Plug this cable into the RI-310 connector labeled “ACC”.

16.  Re-inspect all cables very carefully. Make sure that you do not have any incorrect connections. You should have

three cables that are not connected to anything.

17.  All input and output audio levels have been preset for the Vertex repeater. However, the receiver and transmitter

audio levels will need some final adjustments before you are completely finished. See Section 7 for details on this
procedure.

18.  Adjust the potentiometer on the top of the VXR-5000 “TX UNIT” to mid position. This is the rough modulation level

for the DCS encode data.

19.  Because the RI-310 controller may key up the repeater at any time. Make sure that you install a dummy load on the

“TX ANT” connector before you reconnect power to the repeater for testing.

20.  If your repeater frequency was not programmed into the RI-310 at the factory, you will need to install the

programming cable into the RI-310’s “MIC/PROG” jack. Connect the other end to your PC.

21.  Connect power the repeater and use your RI-300 programming software to set the RX and TX frequency of the

repeater, see VXR-5000 FREQUENCY SETUP later in this section.

22.  Once you have the repeater on the air, you can follow the rest of the Vertex initialization procedure in this section.

This will enable the LEDs on the front panel of the repeater.

23.  Before you are done, continue with the rest of this section set up the transmitter high and low power levels.

24.  Although the audio levels are preset at the factory, you will need to make some final adjustments before installing your

repeater. See section 7 for detailed information on this subject

Changing Transmitter Power Level on the VXR-5000

If you have enabled the above macros in your VXR-5000 and need to adjust the transmitter power level, use the following
procedure:

1. Connect a wattmeter and dummy load to the VXR-5000 transmitter.

2. Connect your computer to the controller using the programming cable. Run the RI-300 Programming Software and open
your controller’s data file. If you do not have a data file for your controller, do a get data from the controller and save this
data as your controller’s data file.

3. In the programming software, pick “Repeater” then pick “Frequency Setup”.

4. Pick the “Force Transmitter On, 30 Seconds” button. Then adjust the “Transmit Power Level” slide bar while reading the
wattmeter for your high power setting (equal to or greater then 10 watts) and record this DAC value below.

5. Now adjust the “Transmit Power Level” slide bar while reading the wattmeter for a 10-watt low power setting and record
this DAC value below.

6. Return the “Transmit Power Level” slide bar to your high power setting, pick the “Send” button and then the “Start”
button. This will update the controller with your new high power setting.

7. Close the “Frequency Setup” window. Next, you will need to modify the transmitter power level macros.

TX High Power DAC Setting __________ at __________ watts (equal to or greater then 10 watts).

TX Low Power DAC Setting __________ at 10 watts.

Note: Vertex recommends NOT setting the transmitter power below 10 watts output or above 25 watts.

8. In the programming software,
pick “Commands” then pick
“Macro Data”. In the “Macro

Plug the temperature sensor cable assembly into the connector labeled "Temp" on the RI-300 or RI-310. Next to the temp
connector is an adjustment that can be used to calibrate the temperature. You will need a reference temperature for this
calibration. Do not mount the sensor to the TX heat sink for calibratio n.

After the sensor's temperature has stabilized:

1. Unlock the controller.

2. Send S-Command 30*12 and the controller will read back the temperature.

3. If an error in the temperature is detected adjust the calibration potentiometer up or down, about 1/4 turn per 1°F

4. Repeat step 2 and 3 until the controller reads the correct temperature.

INSTALLING THE REMOTE BASE INTERFACE (RBI-3)

The RBI-3 cannot be installed into the RI-310 as some of its features are already included on the RI-310. The Remote Base
Interface board adds various features to the RI-300 controller. For additional details, see the schematic in section 17. These
features include:

• 1 non-repeating audio port (input and output) with level adjustments.

• 7 digital inputs (5V logic). These bits are accessed via S-Command 45, bits 09 through 15

• 7 digital outputs (Open collector). These bits are accessed via S-Command 46, bits 10 through 16.

• 2 8-bit DAC outputs (0-5V). These DAC outputs are accessed via S-Command 13.

• 1 PLL serial data channel. S-Command 91 and 92 are used to set up this PLL channel.

• 1 Analog input (S-Meter). See section 4, “Analog Input (Pin5)” for more information.

To install your Remote Base Interface board (RBI-3), use the following steps.

1. Turn off power to the repeater and controller.

2. When working on your controller, use proc edures to assure no static discharge occ urs through the controlle r or Audio
Delay board.

3. Remove the cover of the RI-300 then remove the radio interface connector mounting studs and 2 screws that hold the
analog board to the chassis.

4. The analog circuit board is the board that has a small transformer. Just behind the radio interface connector, you will find a
black 26-pin socket header. Plug the RBI-3 into this header, making sure all pins align. The DB-25 connector on the RBI­3 should align in the same direction as the radio interface connector.

5. Carefully re-inspect your installation, making sure that you have all pi ns correctly aligned.

6. Re-install the analog board and RBI-3 into the chassis, installing the 4 mounting studs on the 2 connectors.

7. You are now ready to use your RBI-3.

RBI-3 Jumpers

On the RBI-3 you will notice 5 jumpers labeled JP301 to JP305. The following details the function of these jumpers.

JP301 - PLL Clock Polarity:

This jumper controls the polarity of the Clock signal. Installing this jumper to the left provides a positive polarity
signal. This position is used for most applications.

JP302 - PLL Latch Enable Polarity:

This jumper controls the polarity of the Latch Enable signal. Installing this jumper to the left provides a positive
polarity signal. This position is used for most applications.

JP303 - PLL Clock Select Enable

Installing this jumper enables the ECK signal to be turned on and off by the serial chip select (SCS) signal. Install this
jumper for most all applications.

JP304 - PLL Latch Enable Select Enable

Installing this jumper enables the ECK signal to control the latch enable signal. Install this jumper for most all
applications.

JP305 - Bit-16 Output / DAC-2 Select

Due to the lack of pins on the DB-25 connector, bit-16 output and DAC-2 output are shared on pin 13 of the
connector. Use JP305 to select which of these outputs are routed to pin 13.

RBI-3 Connector Pin Out

The RBI-3 uses a 25-pin DB type connector to provide
various signals as follows:

DIGITAL INPUTS (Pins 6, 7, 17 and 22 through 25): The
RBI-3 has 7 digital inputs that can be used to trigger macros.
These are C-MOS gates with a voltage swing of 0 to 5 VDC,
TTL level. All digital inputs have 10K pull up resistors. Your
application must “pull down” or sink current with either a
transistor or TTL gate or equivalent. Upo n de tecting either a
rising or falling edge or change in the state of an input, the
controller can be programmed to automatically execute a
macro. See S-Command 46 for additional information on
programming these inputs. Input bit 12 on pin 6 doubles as a
COS input when connected to a remote base radio, see S-

Command 92.

DIGITAL OUTPUTS (Pins 4 and 8 throug h 13): The RBI-3 has 7 digital outputs whose states can be modified by S­Command 45. Each of the 7 outputs can be individually commanded or forced into the high or low logic state. These are open
collector NPN transistors and can sink up to 120ma each and can sink current from a voltage sources as high as 24 volts.
Output bit 10 on pin 4 doubles as a TX or PTT signal when connecting to a remote base radio, see S-Command 92. Output bit
16 on pin 13 can be jumped to DAC 2 in place of the digital out. See jumper details on previous page.

DIGITAL GROUND (Pin 21): Use this as a common for the digital inputs and outputs.

ANALOG INPUTS (Pin 5): The RBI-3 has one analog input that can be directly read as a voltage in the range of 0 to 3.75

volts. This input can also be connected to your radio's limiter output for a Signal Meter function. In some S-Meter
applications, you need to provide a method for scaling the voltage connected on this input. When reading this signal over the
air, use speech control word 014 for the analog voltage and speech control word 013 for S-Meter.

AUDIO OUTPUT (Pin 3): This is a receiver audio output and is programmable with S-Command 34. This output can be set
for either discriminator or de-emphasis audio. The audio on this output is 0dbm or 0.774Vrms for 5KHz Deviation. See
section 16 “Setting Up Audio Channels” for setting up audio on this o utp ut.

AUDIO INPUT (Pin 2): This is audio input that can be routed to the transmitter and is programmed with S-Command 35.
The audio on this input should not exceed 0dbm or 0.774Vrms for 5KHz Deviation. Normally with the RI-300’s Auxiliary
buss, you can select input channels to use. But with this input, audio in is enabled when any of the auxiliary buss input channels
are enabled. This input can be set for either flat FM modulation to the transmitter or with pre-emphasis. See section 16
“Setting Up Audio Channels” for setting up audio on this input.

AUDIO GROUND (Pin 15): Use this to connect to the shields of your audio cable.

DAC 1 OUTPUT (Pin 16): This is an 8-Bit DAC that can output 0 to 5 volts at 10mA. S-Command 13 1 controls this DAC.

+5 Volts (Pin 1): This output can be used to supply +5 volts for your circuit. Do not draw more than 25mA.

POWER GROUND (Pin 14): Use this pin with the +5V and/or DAC outputs.

PLL Data (Pin 18): This output is used to supply frequency data to a synthesized remote base radio.

PLL Clock (Pin 19): This output is used to clock the frequency data to a synthesized remote base radio.

PLL Latch Enable (Pin 20): This output is used to latch or sto r e the freq uency data to a synthesized remote base radio.

SECTION 7 ADJUSTMENTS

Adjusting the audio levels in your controller is very important, in order to avoid clipping or distorted audio. In this section you
will find various features in the co ntroller to help you thro ugh is process.

The RI-310 is shipped with audio levels already set for the Vertex repeater, however final adjustments may be required. If you
are installing a RI-300 or checking the RI-310 audio levels, use the following procedure.

Warning: Refer to section 8, Initialization procedure. W hen a full controller initialization is p e rformed all digital pot settings
are returned to their default settings. Do not perform the initialization procedure at this time. During full controller
initialization, all system settings, user commands, macros, messages, and digital pot settings will be returned to their defaults.
While holding down the initialization button, apply 12 VDC power. After all the LED’s are turned on, you can release the
initialization button and only the system data will be modified. If you continue holding the initialization button for more than
fifteen seconds, the digital pots will be reset.

Note: If you are having startup problems, check the following items.

1. When entering your password for the first time, make sure the COS, CTCSS and DTMF status LED’s are operating
properly. Most of the startup problems will relate to discriminator audio level too low, too high, too much DTMF twist
and/or audio distortion (or CTCSS level too high or low). If your discriminator does not have adequate filtering of the 455
kHz (second IF frequency), you will have to provide for this filtering between the radio and controller. The RI-300 design
has a wide dynamic range for all of the decoders and should work in most conditions.

2. The un-key of your radio when sending a command is a normal command termination. If you are experiencing a problem
when getting started or the COS is always on, you can send a command as normal and wait about 3.5 seconds from the last
digit for the controller to try to process the command.

3. If you experience some problems decoding DTMF, the likely problem is that the tone levels are out of range. The DTMF
decoder has a 30+ dB dynamic range, so that decoding DTMF should not be a problem with a reasonable discriminator
input level. The DTMF status LED illuminates when a tone is first decoded and remains lit until after, either a function
complete or at the completion of a DTMF Inter-digit time-out. If you experience problems where one row or column that
did not decode properly. You may need to check the receiver level or frequency response. To test this, you send one digit

SETTING SQUELCH GAIN (S-COMMAND 50)

The RI-300 uses digital pots for most of its audio level settings. The digital pots have electrical shaft positions called steps.
Each pot has 64 steps, ranging from 0 to 63. S-Command 50 is used to set the squelch potentiometer to specific steps or allow
up and down control of the potentiometer. Each digital pot in the RI-300 has a default setting. See Section 12 for details on
each default setting. If the squelch is open (COS LED on all the time), it will be necessary to let the DTMF inter-digit timer to
timeout to get the controller to accept any command, including the password. The following procedure will outline how to set
up the digital squelch potentiometer.

S-Command

1. 123456 Unlock the controller with your password, you are now in programming mode.

2. 50 [Level] Enter the squelch pot value where the level is a pot step value between 00 and 63. The factory default

3. 50 40 Try sending a larger level setting if the COS LED is still on (3 seconds after you un-key).

4. 50 20 Try sending a smaller level setting if the squelch is too tight.

5. For best performance, set the squelch level 4 to 5 steps above the closed squelch threshold.

6. 69 1 Lock the controller and save your changes.

Do not attempt to set the squelch at the squelch close threshold. The
SmartSquelch works best with a setting of 4 to 5 above the closed threshold.

You can also use the programming software to set the squelch level
potentiometer.

1. Run the programming software and open your repeater data file.

2. Pick “Repeater” then pick “Squelch Setup”.

3. Using the “Squelch Level” slide bar, decrease the squelch setting until the
COS LED on the controller is lit.

4. Then increase the slide bar until the COS LED just goes out.

5. Increase the slide bar another 4 to 5 counts.

6. Pick the “Send” button then pick the “Start” Button. This will permanently
save this setting to the controller.

7. Pick the OK and save your data file.

Description

SMARTSQUELCH, NORMAL and EXTERNAL SQUELCH OPERATION

One of the most powerful features of the RI-300 controller is its built-in squelch circuit (COS). The RI-300 squelch circuit uses
a discriminator noise band-pass filter, an adjustable amplifier (adjustable gain), an AC to DC conversion stage, into an ADC
(Analog to Digital Converter) and then into the micro-controller. By using the micro, all the significant parameters of a squelch
circuit can be implemented in software and are remotely configurable. In the normal squelch mode, the squelch will operate
similarly to that of a standard radio. You can change the squelch level and adjust the upper and lower squelch threshold if
needed. In the SmartSquelch mode, the micro-controller performs math functions that are operated by an algorithm, resulting in
a high performance squelch system. Many parameters of the SmartSquelch are remotely adjustable. The squelch starts with a
fast 10 ms decay delay and extends this delay depending on the quality and type of the signal on the repeater’s input.
SmartSquelch also has another useful feature, the “weak signal message”. If the RI-300 detects that a user is not full quieting
on the repeater input, it will change the courtesy message to the “weak signal message”, in place of the normal courtesy
message.

A third squelch mode is provided for connecting to external squelch circuits. When using this mode, connect your external
squelch circuit to the Pi-1 digital input. This signal should be a 5 volt logic or open collector, active low.

SECTION 8 OPERATION

Once you have connected your controller to a receiver / transmitter and adjusted the audio, you should then confirm its basic
repeater operation. This can be done by transmitting a carrier in the input of the repeater and observing the “COS” LED
turning on and off when you key and un-key. You should next see the “PTT” LED turn on while the repeater transmitter is on.
Next, you can confirm the repeater audio path by listening to your self on the output of the repeater. Finally, if you transmit a
carrier with a 100Hz CTCSS tone on the input of the repeater, you should see the “RPT-TSQ” LED go on and some other
LED’s flashing. The flashing LEDs will be described later in this section.

SYSTEM STATUS INDICATORS

The system status LED indicators will display the current status of the controller. S-Command 09 is provided to enable or
disable (turn on or off) all status LEDs. Turning off the display will lower the current drain of the controller and may be
important in a solar powered or portable repeater configuration. With the status LEDs turned off, the controller will draw less
than 140 ma. During the controller power on
self-test, the RI-300 will turn on all of the status
LEDs for about 1 second.

DTMF COMMAND INPUT

Dual Tone Multi Frequency (DTMF) is typically used in the telephone system for dialing. The RI-300 uses DTMF as the
primary means for the owner and users to control and communicate with the repeater. DTMF is made up of eight tones with
two of the eight turned on in each of the sixteen keystrokes. DTMF is used because of the reliability and ease of use in the
audio transmission range. When sending commands to the controller, you must send each DTMF digit with a delay of 3.5
seconds or less between digits. Then un-key the transmitter. This action is the same as the "enter" key on your computer
keyboard. If the squelch is open or not properly set, the controller will not be able to detect the un-key action. In this case you
can wait for the inter-digit timer to expire, at which time the controller will attempt to process the command. Once the
command is sent, the controller will respond with one of three actions.

1. CW “OK” is a result of a successful command.

2. Speech “ERROR” is a result of an error in the data of a S-Command or macro.

3. No response, the controller did not receive the command or the command was not valid.

using state of the art devices. All standard and non standard EIA CTCSS tones can be decoded or encoded. You may select 1,
2, 3 or up to all 50 CTCSS decode tones to operate the repeater. The controller has divided CTCSS decode into six
independent tone panels. This allows you to assign a di fferent group of tone s for different functions. These tone panels have
the following functions:

Tone panel #1: Repeater audio only. (RPT-TS LED)
Tone panel #2: User commands Control. (Flashing DTMF LED)

This tone panel allows access of user commands.
Tone panel #3: S-Commands and Programming. (Flashing SYSTEM LED)

This tone panel allows access to S-Commands and programming.
Tone panel #4: Auxiliary output audio. (Flashing AUX LED)

Used when connecting two controllers are connected together for linking and remote base operation.
Tone panel #5: Telephone audio and dial commands. (Flashing HOOK LED)

Used to access, dialing and pass audio to the telephone interconnect. When setting up the telephone tone

panel, include the same tones/code in the repeater and user command tone panels.
Tone panel #6: Dial Click. (Flashing DIAL CLICK LED)

Used for dial click commands, see S-Command 49 for more information.

The controller comes programmed with 100 Hz CTCSS tone ready for use in all six tone panels. The default tone may be
changed or additional tones added, see S-Command 20 or the programming software. Once you have selected the tones that
you want to decode, you will need to enable each of the tone panels.

2 (User Commands) 14 1 1
3 (S-Commands) 14 2 1
4 (Auxiliary output) 34 3
5 (Telephone audio) 72 1
6 (Dial Click) See S-Command 49

Each tone panel will display valid decode activity on the front panel of the controller by means of the LED display.

1 (Repeater) TSQ Continuous
2 (User Commands) DTMF Flashing 4Hz
3 (S-Commands) SYS Flashing 4Hz
4 (Auxiliary output) AUX Flashing 4Hz
5 (Telephone audio) HOOK Flashing 4Hz
6 (Dial Click) Dial Click Flashing 4Hz

CTCSS encode tones may be any one or more of the 50 standard and non-standard tones (S-Command 21 and 22). The encode
deviation level can be adjusted up and down from the default level (S-Command 23). The received or incoming CTCSS tones
may be passed to the repeater transmitter, or filtered (removed with a high pass filter, with no tone going out to the repeater
transmitter). Under normal conditions, you will filter out in incoming tone and re-encoding a new CTCSS tone either on the
same or a selected different frequency. This CTCSS encode mode is set by S-Command 21.

The CTCSS encode level is remotely adjusted with a digital pot in the same manner as the transmitter modulation, except with
S-Command 24. The CTCSS encoder generates tone on the voice audio path.

EVENT SCHEDULER (RI-300, Version 2)

The RI-300 has a time of day scheduler which can be used to automatically execute commands at pre-programmed times of the
day. For the scheduler to work, the system time clock must be set, using S-Command 43. See the programming section for
more details. The scheduler uses the system clock to determine when to execute a command. Because the system clock does
not have a battery backup, it must be reset each time the power is restored to the repeater controller. You can also enable a
courtesy message trigger that will let you know when the time clock needs to be reset.

Enable the “CLOCK NOT SET” Courtesy Message

1. Unlock the controller, send the password and un-key, you will hear a function complete.

2. Change the clock not set trigger from the standar d courtesy message to the CW “RST” message, send “32 0 3 21” and un-

key, you will hear a function complete.

3. When you are done, send “69 1” to lock the controller and save your changes. If needed, you can also send a “69 0” to

lock the controller and exit S-Command mode without saving changes.

4. You will now notice a new courtesy message.

Once the system time clock has been set and the schedulers have been set up the command will be automatically executed.
Sixteen individual schedulers are available. To set up the scheduler, use S-Command 44. See the programming section for
more details.

The RI-300 can also execute commands based on many other timed and internal events. See S-Commands 40 through 48 for
additional information on this subject.

EVENT SCHEDULER (RI-300e, Version 3)

The RI-300e has a time of day and date scheduler which can be used to automatically execute commands at pre-programmed
times of the day, week or year. For the scheduler to work, the system time clock must be correctly set, using S-Command 43.
See the programming section for more details. The scheduler uses the system clock to determine when to execute a command.
This system clock is a battery backed real time clock and will continue to keep time even when power is removed form the
controller.

Once the system time clock has been set and the schedulers have been set up the command will be automatically executed.
Thirty-two individual schedulers are available. To set up the scheduler, use S-Command 44. See the programming section for
more details.

The RI-300 can also execute commands based on many other timed and internal events. See S-Commands 40 through 48 for
additional information on this subject.

LOCAL MICROPHONE and SPEAKER

The RI-300 has a local microphone jack that supports all Vertex type microphones. You can use this input to directly talk on
the repeater transmitter. The audio from the microphone will mix with the repeater audio. You can also set S-Command 23 to
control which CTCSS/DCS tone is generated with local microphone activity. You can also use a DTMF equipped microphone
for controlling.

The speaker jack will drive an 8-ohm speaker. This output is the same audio as routed to the repeater transmitter. There is no
level adjustment available on this output.

There are two types of control operations, user commands and system commands.

1. The system commands (S-Commands) are the principal means for the repeater owner to configure and control the

RI-300's basic operation. These commands typically change the characteristics of the system or turn on/off functions of the
system.

2. The user commands are commands that the repeater owner builds to customize the repeater for the users.

INITIALIZATION PROCEDURE

There are two distinctive methods of re-initializing and returning to the factory default data. Default data for each of the
S-Commands is listed in section 12 and the System Command Table at the end of this manual. To initialize the RI-300 data,
use the following procedure:

1. Turn the power to the RI-300 off.

2. While depressing the initialization button, turn the po wer back on.

3. Wait until all the status LEDs turn on for two seconds and then release the initialization button.

4. During this initialization procedure, all default data excep t for the audio level digital pot positions, which were loaded into

the repeater controller’s “EEPROM” non-volatile memory. During the writing process to the EEPROM, all status LEDs
will remain on (approximately 8 to 10 seconds).

5. If you need to initialize the digital pot audio levels, during the power on initialization, continue hold ing the initialization

button for more than fifteen seconds. Then release the button. This initialization loads all default data including the audio
level digital pot positions. Also during the pot initialization, you may hear the controller produce a CW “OK” when it has
completed.

Pressing the initialization button while power is applied after the power on reset is complete will not change any data or be
detrimental. After the power has been on for 2 to 3 seconds, the initialization button can be pressed to turn the LED display
into a receiver audio level meter.

SECTION 9 INITIAL SETTINGS

This section will cover some items that you will need to modify before you put your repeater on the air. But first, confirm the
following items to make sure that your controller is operational.

1. Turn on the power to the repeater. The system LED should be the only LED on.

2. Apply a carrier without a CTCSS tone on the input of the repeater. The COS LED should come on.

3. Apply a carrier with a 100 Hz CTCSS tone on the input of the repeater. The COS and the CTCSS/DCS LED should come

on. The SYS, AUX, DTMF, DIAL CLICK and HOOK LED’s should be flashing 4 times per second.

4. Apply a carrier with a DTMF tone on the input of the repeater. The DTMF LED should be on continuously.

User and System Command Modes

The controller is always in one of two modes: (User Command mode or System Command mode) but never in both.
Commands sent via DTMF will be interpreted depending upon the controller mode at the time that the command is received.
When the power is first turned on, the controller is locked, and is in the User Command mode. When the controller is in this
mode, you will hear a single tone courtesy each time you un-key with a full quieting signal. If your signal is not full quieting,
the courtesy will change to a dual tone courtesy each time you un-key: (Weak signal). After receiving the programming
password in the User command mode, the RI-300 unlocks and will switch to the programming (System Command) mode.
When the controller is in this mode, you will hear a 2-tone courtesy each time you un-key with a full quieting signal. Be aware
that even in this mode, the courtesy will change to the weak signal courtesy if your signal is not full quieting

Command acknowledgment

Each time you send commands to the RI-300, you will get one of 4 responses. First, if you send any valid command without
errors, the RI-300 will respond with a CW acknowledgment message “OK”, or a function complete message of your design.
The “OK” message is of low pitch and has the rhythm of “dah dah dah dah di dah”. Second, you may hear a speech read back
of the data you had sent. Third, if you send an S-Command with an error or a user command that has an e rror in it’s
programming, the RI-300 will respond with a speech message: “ERROR. Fourth, if you send an invalid command, the RI-300
will not respond with any message.

When you are programming your RI-300 over the air, it is important to have a full quieting signal at the repeater. With a noisy
signal, digits can be missed and the result of the command may not turn out the way you planned. The following is a list of
some common problems people have encountered:

• If you key up and send the first digit of the command before the CTCSS or DCS decodes a valid tone, the first digit is

missed and the remainder of the command received becomes invalid - worse yet, looks like some other valid command.

• If you move in and out of a RF null while sending a command such as when using a hand held, a digit may get missed. The

received command then becomes invalid or worse yet, looks like some other valid command.

• If the RI-300 is in the User Command mode while you are trying to send S-Commands, or the controller is in the

S-Command mode while you are sending User Commands, you will not get the results you are expecting. Note that if 5
minutes have past without sending a command while you are in the S-Command mode, the controller will lock itself. If the
time-out should happen, you will hear an unexpected CW “OK”, or a function complete of your design, automatically sent
by the controller.

• Listen to the speech feedback from the controller when sending a system command. This telemetry will help you to

determine that your command was correctly executed.

SETTING UP YOUR STATION ID

You are now ready to change or set up the station identification,
following will show you how this ID was programmed into the controller. Once you have reviewed this procedure, you may
want to review section 14 for more details on programming messages before you start programming your own ID. You can also
use this same technique to modify any of the system messages.

Each character of the ID message has a 3-digit command number. See the default CW data table in section 12,
S-Command 31 for a list of all CW commands. The data (CW commands) for all messages are stored in the same memory area
as the macros. Take care when entering a new message or changing a message, to avoid damaging other data in the memory.
The default “Hello” message uses the following CW commands:

Character 1 = 001 Start Of Message
Character 2 = 036 Set Tone Generator 1 to 400 Hz tone
Character 3 = 079 Set Tone Generator 1 to output level 15
Character 4 = 118 Turn Tone Generator 2 off
Character 5 = 212 CW Speed, 16 WPM
Character 6 = 239 CW “H”
Character 7 = 236 CW “E”
Character 8 = 243 CW “L”
Character 9 = 243 CW “L”
Character 10 = 246 CW “O”
Character 11 = 002 End Of Message

As you can see in the above example, all CW commands have a start of message and a end of message. The body of the
message is contained between the start and end.

ID message

. The factory default CW ID is “Hello”. The

SET CTCSS/DCS ENCODE

The RI-300 controller comes pre-programmed with CTCSS/DCS regenerate mode on. This means that when an enabled
repeater CTCSS tone or DCS code is decoded, the same tone or code is re-encoded on the repeater output. If you need to turn
off the encoder, or if you want to encode only one tone at all times, you will need to change the mode of S-Command 22.
See section 12 S-Command 22 for more details.

YOUR CONTROLLER SERIAL NUMBER

On the backside of the PC Board or mounting panel, you will find a label with your controller serial number. It is important to
make note of this number in a safe place. Use the space provided in this section to make note of the serial number. This
number can be used with S-Command 58 to remotely reset the controller (same as cycling the power to the controller) or with
S-Command 59 to remotely re-initialize the memory.

Controller serial number _______________________

CHANGING YOUR PASSWORD

The controller comes pre-programmed with “123456” as the password to access the System Command (S-Command) mode.
You can select a new 1 to 6-digit password. You can use any of the DTMF characters in your password except for “C”. Do not
use “C” in your password. To reduce additional problems, compare your
new password with the system commands to make sure it does not look like
a system command. Example, do not use “010” as the password. If you are
in the S-Command mode and accidentally send this password, you will turn
off the system instead! Oops!!

You can also use the programming software to edit this message. Pick
“Repeater” then pick “Passwords and Key code”. You may then edit the
“S-Command access” from this dialog box.

S-Command

1. Pick your new password, 1 to 6 digits. The default is 123456.

2. 123456 Unlock the controller, you are in S-Command mode.

3. 55 ?????? Enter S-Command 55 and your new password.

4. 55 Use the 55 S-Command without data to read back your new password.
Be careful. Reading back your password over the air will allow other people to hear your password.

If you make any mistakes, re-enter your new password. If you lock the controller with a mistake in the password, you will have
to reset to all the factory defaults to regain access to the S-Command mode again.

5. 69 1 S-Command 69, Lock the controller and save your changes.

6. ?????? Check your new password, send “(Your password)”, you SHOULD hear a function complete “OK”.

7. 69 0 Re-loc k the controller without saving changes.

SECTION 10 AUXILIARY BUSS

The RI-300 has auxiliary input and output capability for connecting as many as eight RI-300 repeater controllers together, or
connecting to a single control receiver. Additional RI-300 controllers will allow interconnection of multiple repeaters, remotes,
links or a repeater with links and remotes. The Aux buss has eight audio channels and a digital serial data path to provide all
the communication that is required when connecting multiple controllers together. For added pro tection, the serial data
communication protocol contains an error check routine. If a controller does not receive valid data within four seconds, that
controller will return to a normal operating mode. This feature is designed to prevent a transmitter from staying keyed-down
because of a serial data communication failure.

CONNECTING MULTIPLE RI-300 REPEATER CONTROLLERS TOGETHER

You can connect multiple RI-300 repeater controllers together
using the auxiliary buss connector and a standard 16 pin flat
cable. The cable should be pin to pin. Up to eight co ntrollers
can exist on one cable and the cable should have an overall
length of no more than 6 feet. The auxiliary port has 8 audio
channels in a full cross point configuration. This means that any
controller can be connected to any other controller without
interrupting other controllers on the buss. All controllers will
exchange audio, PTT and command information. The PTT and
S-Command information is sent between the controllers as serial
data. A fixed data time-out timer is included in this protocol to
protect against accidentally keying a transmitter. If data is not
received for four seconds, the controllers will return to a normal
operating mode. Any RI-300 controller attached to the buss can
operate as a repeater, remote or link. This architecture of an
independent controller for each radio port ensures maximum
flexibility and reliable operation of your system.

Auxiliary Buss and Programming Software

The auxiliary buss is disabled when using the programming port on any controller attached to the auxiliary buss, and during
data transfer between the controller and your computer. The buss will be re-enabled when the data transfer is done.

Passing System Commands between Controllers

See section 13 and section 16 for more detailed information regarding this subject, passing systems commands between
controllers.

Command information is sent from one controller to another by writing macros with data telling the controller to send S­Command information to another controller and not to process that S-Command within itself. To build a macro that will
process S-Commands within the local controller, follow all the normal procedures in this manual and in the “Programming User
Commands and Macros” section 13. To build a macro with S-Commands that will be processed by another RI-300 controller,
you simply insert an “Ax” (where “x” is a numeral from 1 to 9) before the S-Command and its data within the macro. All data
from the “Ax” through the “C” (S-Command separator) will be sent to the second contro lle r. Each controller in the system will
be assigned its own controller number. When sending a command to another controller, all controllers with the same controller
number as the “A” number, will execute that S-Command. All “A1” controllers will respond to “A1” prefix macro data. All
“A3” assigned controllers will respond to the “A3” prefixed macro table data.

The controller number is also used to determine which audio channel that controller will use to output audio. You can then
select which controllers you want to interconnect by turning on the correct audio inputs.

Note: T he “controller unit addr ess” is set with S-Command 39 and can be any address 1 thr ough 9. The default a ddress is 1.

Each controller on the buss will need to have its own unit address.

To transfer serial data between controllers, S-Command 38 must be in the default state mode 1 (38 1) serial port data

transfer mode.

SECTION 11 PROGRAMMING

Customizing the RI-300 for your application is performed through programming. Programming is done with (System
Commands) S-Commands and is performed over the air, over the telephone or with the programming software. Not only can
you change any of the system perimeters, but you can also change or create your own user commands.

The RI-300 contains powerful tools in which to create User Commands and macros. User commands are commands that the
user of the repeater will send to perform major functions, like making telephone calls. The user commands themselves will call
macros that can contain many S-Commands. However, with the power to customize your repeater comes the responsibility of
managing the memory where your custom commands will be stored. When creating new user commands, macros or messages,
care should be taken to avoid damaging other data in the memory. See section 13 for additional information on this subject.

When controlling the RI-300, you are always in one of the two modes, never in both. To enter the programming mode the
correct password (section 11) must be executed. To exit the programming mode and return back to the User Command mode
the S-Command 69 0 or 69 1 is executed. Programming or S-Command mode is often referred to as the controller “unlocked
mode” and the user command mode as the controller “locked mode”.

IMPORTANT NOTE: At all times the controller is in one of two command modes:

1. Normal operating mode where User Commands are functional (Locked).

2. Programmi ng mode where System Commands (S-Commands) are used to customize the controller (Unlocked).

PROGRAMMING COMMAND FORMAT

Syntax is a common computer term, which means the format of a statement, command, or data that must be organized and
entered such that the computer can recognize or understand what you are telling the computer. The syntax of an S-Command
consists of a two digit number ranging from 00 to 99, which identifies the S-Command itself. The S-Command is followed by
data of various types and amounts. Each of the S-Commands listed in section 12 will detail its own syntax.

SPEECH READ BACK

Most all S-Command data can be read back in speech. This read back occurs when modifying non sensitive system data.
Passwords and user commands do not automatically read back. Nearly all commands will read back system data without
making modifications when the command is sent in the read back form.

PASSWORD ACCESS

Prior to the access of any System Command or S-Commands, you must enter the valid password. Upon receipt of the valid
password the RI-300 controller will return an acknowledgment message (speech “U” “L”). At that time any system or
S-Command may be issued. Any valid S-Command will also return the acknowledgment message (CW “OK”) or sometimes
called a “function complete” telemetry or speech of the modified S-Command data. If the controller did not understand the S­Command you will get a speech “ERROR” message.

The controller comes programmed with “123456” as the password to access the system command mode. You can change the
password within the range of 1 to 6 digits. To reduce additional problems, check your new password with the system
commands to make sure it does not look like a system command. Example, do not use “010” as the password. If you are in the
system command mode and accidentally send the password “010”, you will turn off the system instead.

Page 39

Pacific Research Solutions RI-300e User Manual

1. Pick your password, 1 to 6 digits. The default is 123456.

2. Unlock the controller, send “123456” and un-key, you will hear a function complete “OK”.

3. Enter your new password, send “55 (Your password)” and un-key, you will hear a function complete “OK” not speech read

back as this is considered to be sensitive data.

4. You can check you password by sending “55” without data. Remember that the controller will read back your password

over the air if the command was sent over the air.

5. If you make any mistakes, re-enter the new password. If you lock the controller with a mistake in the password, you will

have to reset all the factory defaults to return to the default password. You can also use the programming software to fix
the password.

6. When you are done, send “69 1” to lock the controller and save your new password.

7. Check your new password by sending “(Your password)” and un-key, you will hear “U” “L” in speech.

8. Re-lock the controller, send “69 0” this time, you do not need to save anything.

Forgot your Password?

Should you forget your password, you will have to turn off power to the RI-300 controller, then simultaneously hold down the
initialize switch on the controller and apply power to the controller. The controller will restore all of the factory default data.
The password will again be the default 123456 and you will have to change it to a new secure password. You will also have to
change all the default data to the desired settings again. Keep good notes on all S-Commands, their data, user commands and
macros.

Some common Password problems

If the receiver input level or squelch is not set up correctly, the COS LED on the front panel will not go out. You need to check
the receiver input level (Section 7) and/or adjust the squelch (Section 7). Until the squelch is properly adjusted, you will have
to wait for the inter-digit timer to expire before the controller will process a command.

Another problem is the different modes (Unlocked and Locked) that can be confusing. After you enter the correct password,
you then hear a “U” “L” speech message. A moment later (by mistake) you enter your password again. During this and
following attempts, you receive an “ERROR” message. What happened? When the first password was executed and the
controller was unlocked , you moved into the S-Command (programming) mode. While in the S-Command mode, (and if your
password does not look like an S-Command) you should, and will, get an “ERROR” message because the controller was
expecting an S-Command and saw your input as an S-Command with bad data. If your password looks like a valid S-Command
to the controller, you will have executed an unexpected S-Command instead of the password. For example, if the default
password were 123456, the response to the first time you entered the password would be a “U” “L” message. If you were to
send a 123456 again, the controller will think you are trying to send a “12 3456” (which tries to set the repeater TX level to an
invalid level). The controller should, and will, respond with an “ERROR” message.

Make sure to always re-lock your controller by sending the S-Command 69 1 (to save your change s) when you are finished
programming. If you make a mistake while programming, you can send S-command 69 0 to lock your controller and NOT save
your changes. There is also a time-out timer on the controller. When the controller is unlocked, the timer will automatically re­lock the controller 5 minutes after the last valid S-Command. When this occurs, you will hear “L” “O” “C” “K” in speech.
Note that the controller will NOT save your changes when this timeout occurs.

Auxiliary Controller Password Access

You can unlock and perform system commands on a controller attached to the auxiliary buss from any other controller when
you have multiple RI-300 controllers attached on the auxiliary buss. You may unlock another controller on the buss by adding
an Ax (“x” is the controller address number you want to unlock) to the end of the local controller’s password. Once another
controller on the auxiliary buss is unlocked, you can send S-Commands to that controller in the usual way.
Use the following example:

1. Assume the local controller’s address is #1 and its password is 123456.

2. Assume another controller on the auxiliary buss has an address #2 and its password is 987654.

3. From the local controller, send “123456A2” and un-key. You will hear the “U” “L” message.

4. The controller at address #2 is now un-locked and you can send S-Commands to that controller in the normal format.

5. When you are done, send S-Command “69 0” or “69 1” to lock the controller at address #2.

Pacific Research Solutions RI-300e User Manual

VALID S-COMMAND and DATA

All DTMF digits are valid either as data in an S-Command or as macro data. Sometimes the DTMF character “C” and “D” is
not valid as S-Command data within macros. The “C” and “D” characters are used by the macro programming. The RI-300
will check all data within an S-Command. If any of data fields are out of range, have an incorrect number of digits or have
missing digits, the RI-300 will ignore both the S-Command and its data and will return an error message.

RULES FOR LEADING ZEROS IN S-COMMANDS

Leading zeros means that if a command requires a 3-digit value, whether the value is 001 or 100, a total of three digits must be
used. All S-Command codes are two digits long. If the first digit of the S-Command is a zero it must always be entered. For
most S-Command data, use the following rules:

1. If the data is a single parameter, then leading zeros are not required for the data. Example: The controller will see 01 or 1

as the same value if used as the last parameter.

2. All commands that require multiple parameters require leading zeros for each parameter except for the last parameter.

Example: Anytime an S-Command requires two data parameters (such as S-Command 40), the first data parameter must
have leading zeros and the second data parameter does not require leading zeros.

3. If you are not sure, always use leading zeros especially when you are not yet familiar with the controller.

Page 41

Pacific Research Solutions RI-300e User Manual

SECTION 12 SYSTEM COMMANDS

The following section will detail each of the S-Commands showing syntax, examples, and the default data values. To execute
an S-Command, you must first “unlock” the controller with the current password. When “unlocked”, user commands will not
work. When you are done, “lock” the controller with S-Command 69 0 or 60 1. S-Command 69 0 will lock the controller
without saving system changes, and 69 1 will lock the controller, saving the system changes. Some items are saved at the time
you send the S-Command. The rest are saved on exiting the S-Command mode (S -Command 69 1). This di fference is noted
with each S-Command in the “SAVE” field as “RAM/EEPROM”.

The controller is always in one of two modes, (User Command or System Command) and never in both. When the power is first
turned on, the controller is locked and in the User command mode. In this User mode, you will hear a single tone courtesy each
time you un-key with a full quieting signal. If your signal is not full quieting, the courtesy message will change to a dual tone
(indicating a weak signal). After you send the programming password, the RI-300 unlocks and will switch to a programming or
System Command (S-Command) mode. In this programming mode, you will hear a 2-tone courtesy each time you un-key with
a full quieting signal. Remember that if your signal is not full quieting, the courtesy message will sound a dual (weak signal)
tone – even in programming mode.

Each time you send commands to the RI-300, you will get one of four responses.

1. If you send any valid command without errors, the RI-300 will respond with a CW acknowledgment message “OK”, or a

function complete of your design. The “OK” message is of low pitch and has the rhythm of “dah dah dah dah di dah”.

2. You may hear the speech read-back of the data you sent.

3. If you send either an erroneous S-Command or a user command that has an error in its programming, the RI-300 will

respond with the speech message “ERROR”.

4. If you send an invalid command, the RI-300 will not respond with any message.

When you are programming your RI-300 over the air, it is important to have a full quieting signal to the repeater. With a noisy
signal, digits can be missed and the result of the command may not turn out the way you planned. The following lists some
common problems people have:

• If you key up and send the first digit of the command before the CTCSS or DCS decodes a valid tone, the first digit is

missed, and the command becomes invalid or worse yet, looks like some other valid command.

• If you move in and out of an RF null while sending a command, a digit may get missed, and the command becomes invalid

or looks like some other valid command.

• If the RI-300 is in the S-Command mode, you may get errors if you are trying to send User Commands. Note that if you

are still in the S-Command mode after 5 minutes have past without a command being sent, the controller will automatically
lock. When this happens, you will hear an unexpected CW “OK” without sending a command.

S-Cmd 03 USER COMMAND PREFIX SET UP (Palomar Emulation)

This feature is used to define a command prefix method that will control a local system and/or link system. This function was
primarily designed to require a key sequence that will allow multiple user commands to be functioned without un-keying. This
function can also act as the first character(s) of a single user command. If you chose to allow multiple commands to be
processed, you will need to define a alternate command terminator (S-Command 11) that will help the controller determine
when each command ends. In most applications, a minimum length command terminator is used.

When a command prefix is enabled, the command prefix defines the beginning of the command sequence. This mode is the
same as the “
prefix is decoded on the local repeater port, the contro ller will start looking for valid commands. If the command arrives from
the link port with the correct link prefix, the controller will respond with the pre-access tone. The user may only un-key once,
after the prefix, to confirm the pre-access tone. Once keyed again, or after the first command is issued, the user need not
un-key during the remaining command sequence. The command timer is restarted each time the controller decodes a valid user
command. If the user un-keys, or if a user command reports an error, the command timer expires, or the inter-digit timer (S­Command 16) expires, the command timer is terminated. Additional commands are no longer allowed.

can be used to turn off the function complete and error messages while keeping the ID or courtesy on.

If mode data is set to 1, the controller will temporarily suspend the function complete message or error message. This
suspension of the message is one time only, and does not affect the previously selected global mode. This feature can be used

S-Cmd 10 REPEATER TIMEOUT TIMER

The time-out timer sets the maximum length of a single user transmission, not necessarily the repeater transmitter key time.
When the user’s transmission time has been exceeded, the repeater transmitter PTT is turned off, un-keyed. The COS must
drop and the courtesy message started for this timer to reset. Before and after a timeout, the repeater will send a message to
notify the user(s). These messages are called pre and post time-out messages.

The use of a “*” in the time field will manually reset the timer if a user talks too long or if continuous noise on the repeater
input has timed out the repeater. You can reset the timer by capturing the signal on the repeater input and issuing the time-out
reset S-Command. You may need to wait for the DTMF inter-digit timer to expire before this command is executed. This
command could be sent over the Auxiliary Link or telephone if needed, especially if there has been no user command created to
reset the timer.

SYNTAX: 10 [Time]
READ BACK: 10
STORAGE: RAM/EEPROM
PARAMETERS: Time 0 = Disable time-out, 1 to 255 = tenths of minutes or 6 second increments,

EXAMPLE: 10 10 The repeater will time out after 1.0 minute.

S-Cmd 11 ALTERNATE COMMAND TERMINATOR

In a normal command sequence, the drop of the COS or CTCSS/DCS is used to tell the controller to start processing your
command. You can select an alternate DTMF digit or mode that will also terminate a command, such as if the squelch were not
working or if you wanted to string commands together . Do not select a DTMF digit that you are using within a user c ommand;
that command will not be processed.

If you use a minimum length command terminator, all user commands of less length or telephone and wildcard commands will
be ignored. However, these commands can be processed after the drop of the COS or by the expiration of the inter-digit timer.
If you use the minimum length command terminator, the controller starts looking and comparing standard user commands after
the minimum command digit length has been met.

S-Cmd 15 USER COMMAND DECODE ENABLE

This command is used to turn on or off any one of eight groups of user Command. When you build a user command, you are
asked to identify one of eight groups into which the command is placed. You can then use this command to enable or disable
any one of the eight groups. As an example, all telephone type commands can be placed into group 2 and all other commands
are placed into group 1. When you use the telephone, you can include this S-Command in the telephone user command to turn
off group 1. This means that when the telephone is off-hook, all commands in group 1 are disabled. You could also add a
scheduled function to disable the user telephone commands during the night, for example.

Commands that are placed into group 8 can be accessed directly by the telephone incoming call mode while in mode 6 (S­Command 71) without using the control password (S-Command 57) and with or without group 8 being enabled.

S-Cmd 20 TONE PANEL CTCSS TONE and DCS CODE DECODE ENABLE

The RI-300 controller comes equipped with 6 independent tone panels for 6 different internal functions. These functions
include: Repeater audio, User commands, S-Commands, Auxiliary output, Telephone and Dial click commands. Each CTCSS
tone and DCS code may be independently enabled or disabled for each tone panel. You can have any number and/or
combination of tones/codes enabled. Once the tones you need are enabled, use the appropriate S-Commands (01, 14, 34, 49
and 72) to enable each tone panel for use. You may choose to set up your tone panels with different tones; one for repeater use
only, another tone for a combination of functions: Repeater, User commands and Telephone use. Yet another tone can be used
for just Repeater and S-Commands. This flexibility allows you to customize the repeater for each user.

S-Cmd 21 SET MASTER and CROSS ENCODE CTCSS TONE or DCS CODE

This command is used to set up a master encode tone. This tone is encoded regardless of the tone that was decoded. The
master encode is selected by omitting the cross decode tone number. Cross-encode is a mode in which you specify a specific
encode tone for each of the decode tones that you will be expecting. For example, the controller can be set up so that when

100.0 Hz is decoded, 127.3 Hz tone is encoded. Or, when DCS code 023 is decoded, tone 151.4 Hz is encoded. This
command also works in conjunction with S-Command 25 to select the encode mode or under what circumstances this tone or
code is encoded. When setting up tones for cross encode, a value of 000 in the tone encode field will force the controller to use
the master tone for the selected decode tone. Set the S-Command 22 to mode 3, 5 or 7 to use the cross tone-encoding mode.
Each tone or code has a number assigned to it as listed in the table under S-Command 20.

S-Cmd 23 INTERNAL FUNCTION CTCSS TONE or DCS CODE ENCODE

A specific tone or code may be encoded based upon some of the controller’s internal functions. This command specifies what
tones will be encoded on the repeater transmitter when activity is detected from the ID, auxiliary input, local microphone and
telephone ringing. Besides the 154 tones and codes, there are four additional encode modes that are available when specifying
the encode tone.

1. Tone 0 will disable encoding tones or codes during one of the command functions.

2. Tone 155 will use the last encoded tone based upon the mode of S-Command 22.

3. Tone 156 will use the master tone selected by S-Command 21.

4. Tone 157 will use the tone that comes from another controller at the auxiliary input, based on S-Command 35, source

monitoring.

A common use for this command is to disable the encoder during ID, making the ID quiet on a CTCSS equipped receiver.
Another use is to force a tone to be encoded as a result of a macro function; see function 0 below.

S-Cmd 27 TONE REMOTE DECODE SET UP

This feature is used to set up the tone remote frequencies that you want to decode. You can spe cify up to eight different tone
frequencies. Tone #1 is used as a PTT signal during tone remote operating mode. This tone is typically 2175Hz. This function
can also be used to set the decode tolerance for all tones. In most applications, the d efault ±2% will work just fine.

SYNTAX: 27 [Item] [Data]
READ BACK: 27 [Item]
STOREAGE: RAM/EEPROM
PARAMETERS: Item 0 = (Decode tolerance) Defines the percent tolerance of the tone decoder. It should be noted that

the tone decoder has an initial accuracy of 0.2%. With this feature, you define a window in
which a tone will be accepted. This window is measured by the above tone frequency’s tone,
plus and minus the percent window as defined. For example, if you set the tone tolerance to 2
(±1%), a tone decoder set to 1000Hz will accept a tone in the range of 990Hz to 1010Hz.

= 1-20 (0.5-10%, 0.5% inc)

Data

Item 1-8 = (Decode frequencies) Defines 8 frequencies to be decoded. The frequency is in the range of

650 to 3000 Hz. A zero value will disable a tone from being decoded. You can use the default
standard “tone remote” tones, or define 8 of your own tones. Each of these decoded tones will
activate a user programmable bit (Bits 17 to 24, see S-Command 45). As an example, when
tone #1 is decoded, bit 17 will go high and when tone #1 is no longer active, bit 17 will go low.
You can then use these bits to trigger macros. Tone #1 through #8 controls bits 17 thr ough 24.
When using the tone remote feature (see S-Command 28) tone #1 also acts as a PTT tone and
tone #2 is the monitor. The following table shows default tones and their definition:

S-Cmd 28 TONE REMOTE MODE and NOTCH FILTER CONTROL

This feature is used to define the mode of the tone remote decoder. As a tone decoder, each of the 8 tones as defined in
S-Command 27 is used to set and clear user bits 17 through 2 4, (see S-Command 45). In any the tone r emote modes listed
below, all decoded tones will operate the user bits 17 through 24.

When using any of the tone remote modes, you may need to add a notch filter (NF-3) to the controller. This circuit will strip
away the 2150 Hz PTT tone so that the user will not hear this tone over the air.

Tone Decode

defined by S-Command 45. For example, you can set the receiver tone decode mode to decode a 1750 Hz tone. A successful
decode of 1750 Hz would be used to trigger a macro that would allow access to the repeater.

Telephone Linking

RI-300 or RI-310 controller over a telephone line. In this mode, PTT control signals are passed between controllers in a tone
remote format. Set the telephone incoming call S-Command 71 to mode 2 or higher, and enable S-Command 28 0 mode 4 and
S-Command 28 4 mode 3 on both controllers. Set S-Command 70 to mode 5 on the calling controller, and start an outgoing
call. When the controllers connect, they will handshake with the monitor tone. Use S-Command 45 to build a macro to adjust
timers and play a message over the air to let the user know that telephone linking is operating when the monitor tone is detected.
At this point, you can communicate in the same manner as you would with a radio link. In this mode, the telephone off hook
time out timer (S-Command 77) is used to limit the total length of the connection. The telephone no-activity time-out timer
may be used to disconnect the call, if a period of time occurs without receiver activity. You can use this mode with the standard
telephone call mode by setting up this mode in the telephone linking command and resetting this mode on hang up of the
telephone. See section 15 for more information on this mode.

Receiver Tone Remote

(CTCSS and DCS) may be used with this mode. In this mode, the PTT tone defined by S-Command 27 is used to enable the
COS signal, allowing receiver audio to pass in the controller. This mode will affect all areas in the controller where COS is
used to switch or route audio .

Auxiliary Tone Remote

is detected. This mode works in the same manner as the receiver tone remote.

Two Wire Tone Remote

mode, the telephone is always off hook and ready to pass audio when the PTT tone is detected. When receiver audio is active,
the controller will send the PTT tone out the telephone interface. You can use this mode to connect two repeaters with RI-300
or RI-310 controllers together via a dedicated 2-wire connection. This mode can also be used with a tone remote hand set.
When using this mode, all telephone operations are disabled.

Tone Remote PTT Encode

Command 27 1 defines the P TT tone.

Tone Encode and Burst time

can execute S-Command 28 6 [Tone number] in a macro to send that tone for the burst time. The tone remote decode mode is

S-Cmd 30 SPEECH MESSAGE EDITOR

Speech Messages include the station ID, courtesy tones, telemetry and custom user messages. This command is used to edit
and store speech message data into the system memory. The messages consist of speech control words or speech words in
sequence. Each of these speech commands consists of a 3-digit value and they are used to tell the RI-300’s speech synthesizer
what to do. These commands include 32 control words, a 661-word vocabulary and 50 DVR messages. The control words
allow you to speak the time, S-Meter and many other items with only a single command. The messages are stored in the same
memory area as the macros. For this reason, it is important to manage and track the memory usage so as not to damage other
data stored in the memory.

There are two types of messages that you will be creating and editing.

1. Messages that are triggered by the controller. These are the most common type of messages and include the station ID,

courtesy and telemetry. S-Command 32 is used to define each message that is played when the associated event occurs.

2. Messages that are imbedded within macros. These messages are usually included with S-Commands in the same macro.

These macros are typically triggered by a user command.

The system memory is used to store both macros and messages. The memory is organized with 999 lines of data storage, each
line consisting of 24 digits. All messages and macros must start at the beginning of a line. Each line has a starting number from
001 to 999. Message triggers, user commands and event triggers use the start line address as the start location of the message or
macro. To edit or create a message, you must first set a pointer to the start line where you want to start your message. Do this
with S-Command 63. Next, you can start building your message. In order for the message to work correctly, it must include a
“Start of Message” command (30 001) as the first entry. The next entries are those of the message itself (30 XXX). The
message is completed with an “End of Message” command (30 002), and finally an end of data command: (64) as the last entry.
For the purpose of tracking the amount of digits stored in memory, the “Start of Message” consumes 2 digits “30”. The “End of
Message” command consumes 1 digit “C”. The end of data command consumes 1 digit “D”. All other message commands
consume 3 digits each.

S-Cmd 31 CW MESSAGE EDITOR, TONE GENERATOR COMMANDS

Tone messages include the station ID, courtesy tones and telemetry. This command is used to edit and store message data into
the system memory. The messages consist of either tone generator or CW commands in sequence. Each of these commands
consists of a 3-digit value and is used to tell the RI-300’s tone generator what to do. These commands include setting the tone
frequency, CW code speed, CW character, beeps and pauses. The messages are stored in the same memory area as macros.
For this reason, it is important to manage and track the memory usage so as not to damage other data stored in the memory.

There are two types of messages that you will be creating and editing.

1. Messages that are triggered by the controller. These are the most common type of messages and include the station ID,

courtesy and telemetry. S-Command 32 is used to define each message that is played when the associated event occurs.

2. Messages that are imbedded within macros. These messages are usually included with S-Commands in the same macro.

These macros are typically triggered by a user command.

The system memory is used for both macros and messages. This memory is organized with 999 lines of data storage, each line
consisting of 24 digits. All messages and macros must start at the beginning of a line. Each line has a starting number from 001
to 999. Both message triggers and user commands with triggers use the start line address as the starting location of the message
or macro. To edit a message, you must first set a pointer to the start line where you want to start your message. Do this with S­Command 63. Next, start building your message. For the message to work correctly, you must include a “Start of Message”
command (31 001) as the first entry. The following entries are the message itself (31 XXX). The message is completed with an
“End of Message” command (31 002), then finally an end of data command (64) as the last entry. For the purpose of tracking
the amount of digits stored in memory, the “Start of Message” consumes 2 digits “31”. The “End of Message” command
consumes 1 digit “C”. The end of data command consumes 1 digit “D”. All other message commands consume 3 digits each.

Tone Generator Command Descriptions

TG1 Tone ge nerator #1, you can independently contro l frequency and level of this generator.
TG2 Tone ge nerator #2, you can independently contro l frequency and level of this generator.
TONE Predefined tones, used to set the frequency of the tone generator.
DIR. FREQ. Sets the frequency of the tone generator directly. This command selects the most significant digit of the

frequency, followed by a second tone generator command (31 XXX) that control the three least

significant digits of the actual frequency.
LEVEL Sets the modulation level of the tone generator. “50” is full modulation (5 KHz deviation).
CW SPEED Sets the speed of any CW characters following this command.
CW… A specified list of Morse code characters used in a message
TONE ON Turn on the currently configured tone generator to the defined destination.
TONE OFF Turn off the currently configured tone generator to the defined destination.
TONE ON FOR... Sets the amount of time for the tone generator to be on.
DELAY FOR… Sets the amount of delay between tone generator commands.

Note: When setting tone generator levels for generating DTMF digits, set TG1 to Level 15 (31 079) and TG2 to Level 12

(31 162). This will provide the correct amount of twist needed for reliable decode.

S-Cmd 32 SET MESSAGE and EVENT TRIGGERS

This command is used to assign controller events to trigger messages or macros. Event triggers are items like ID, courtesy
messages, function telemetry and power on events. These triggers point to a starting line in the macro data memory. When an
event occurs, the trigger instructs the controller to execute a message or command from the macro data memory. The default
triggers can be changed so each event can trigger any of the 999 macro line numbers or 0 for no messages. Setting an event to
start at line 0 will disable that event from triggering anything. See section 9 and 14 for additional information in programming
messages and triggers.

Message Trigger:

looks at the value in this event to determine what the address of the message or macro to play.

Event Trigger:

restored to the controller, a Power On trigger occurs on the restart. This trigger then starts a macro. The macro function can be
used to return your repeater to a specified configuration whenever power is turned on. A function complete (“OK” message, or
function complete of your design) will sound when this process occurs.

Auto Patch Trigger:

telephone back on hook. This trigger is used to tell the controller the start line address o f the macro you are using for the on­hook command. If you choose to change the factory default macro start line address for the on-hook command, you will need
to program this trigger to match. If the controller does not know the correct on-hook command start line address, you may have
problems if an on-hook time-out occurs.

S-Cmd 33 DIGITAL VOICE RECORDER, EDIT MESSAGE

The Digital Voice Recorder (DVR) used in the RI-300 provides a high quality solid-state speech record and playback function.
This unit uses a non-volatile EEPROM technology to store the messages. Note that even though the message itself is stored in
the DVR memory, message management information is stored in the RI-300. If you replace or change the DVR, any prior
recorded messages will be lost. After installing the DVR (section 6), use the "33 9 x" S-Command to tell the RI-300 which
model DVR you installed.

The DVR will allow up to 50 messages of variable length totaling the size of the device you installed. You can send
S-Command "33 3 0" to find out how much total DVR time you have used. To record a message, send S-Command "33 1 x" (x
= message number) and un-key. After the prompt, key up and start recording your message. The RI-300 will stop recording
when you finish your transmission. The RI-300 will also edit the end of your message to remove any squelch burst. Next you
can review your message by sending S-Command "33 2 x". If you want to record over an existing message, you do not have to
delete the old message; the controller will do that for you. To include a message in a user command or in an ID message, use
the speech message editor (S-Command 30), selecting Speech Command 901 through 950. Speech Command 901 will play
DVR message #1 and so on.

The RI-300 will stop recording when you finish your transmission. If you are recording a
message from the telephone, send this command, then start the recording by pressing “1” on
the telephone and stop the recording by pressing “0”. The RI-300 will also edit the end of
your message to remove any DTMF or squelch burst. If you want to rec ord over an existing
message, you do not have to delete the old message, the controller will do that for you.

S-Cmd 34 AUXILIARY OUTPUT MODE

The auxiliary port allows you to connect multiple RI-300 controllers together or connect the RI-300 to someone else’s existing
controller. This command sets up the mode for the output of audio and PTT logic to other controllers. The RI-300 has 8 audio
channels connected to the auxiliary buss. Use S-Command 39 to assign a channel on which to output both audio and serial
data. This command is then used to enable audio output on that channel. See section 16 “Setting Up Audio Channels” for more

S-Cmd 39 RI-300 CONTROLLER UNIT ADDRESS

This command is used to assign a unique unit address to each RI-300 connected on the Auxiliary buss. When connecting
multiple controllers together, you must assign each controller a unique unit address. Controllers on the buss can talk to each
other using the serial data protocol if each controller has its own unit address. This unit address also defines the audio channel
on which the controller will output audio on the a uxiliary buss. Valid unit addresses are 1 through 9 with the default being 1. A
controller at address 9 can send and receive commands on the buss, but will not use an audio channel. A controller with a
macro containing a unit address with an S-Command will not process the S-Command in that controller. The unit address and
S-Command is sent to the auxiliary port. This address will be checked against the addresses of all the controllers connected to
the auxiliary buss. A controller with a matching address will execute the S-Command. These externally executable S­Commands start with an “A” prefix and the destination unit address, e.g.: “A2”. The S-Command following the A2 will be
executed by a controller with the unit address of “2”.

S-Cmd 49 DIAL CLICK CONTROL TRIGGER

Dial Click is a method of control with which you can assign a number of key-ups on the repeater input that will cause a user
command or macro to occur. If enabled, one or more CTCSS tones or DCS codes can be used for the Dial Click. If no tones or
codes are enabled, the Dial Click control will use repeater COS only. The Dial Click function uses a 2-second timer to check
the spacing between each Dial Click. When a key up occurs, the timer is started. One Dial click is counted if the user un-keys
before the timer expires. If the user keys up again before the timer expires, another Dial Click is counted. Once the timer has
expired, the program checks to see how many Dial Clicks where counted. This information is then used to trigger a macro start
line. You may need to experiment with a rate of key-ups so that they are properly counted because of the Dial Click timer. If
you key too quickly, the CTCSS or DCS decode delay may not be long enough to correctly count dial clicks. If you wait too
long between key-ups, the Dial Click timer may expire before you are finished.

A single key up Dial Click command works well with the telephone answer S-Command 82 9. The use of 2 and sometimes 3
Dial Clicks to trigger a command may allow unexpected executions, because 2 quick keys or noise on the repeater input may
start the macro. As an example, you can use multiple Dial Clicks to dial a telephone number in the auto dial list using
S-Co mmand 92.

S-Cmd 53 TELEPHONE HYBRID ADJUSTMENT

The RI-300 uses a digital potentiometer to adjust the telephone hybrid circuit. In most cases, the auto setting will work fine. In
auto, the microprocessor will balance the hybrid during each outgoing telephone call in which the off-hook command and
telephone number have been combined as a single command. In some telephone connections where the controller is having
trouble balancing the hybrid, you can manually balance the hybrid. The easiest method is to use the programming software to
adjust the hybrid potentiometer during a full duplex telephone call. Once you are done, you can save the setting. If the
programming software is not available, you can use this command to balance the hybrid. You may have to make multiple
telephone calls while making small changes to the hybrid setting until you achieve the best results. Do not expect a perfect null;

S-Cmd 56 PASSWORD FOR TELEPHONE INCOMING RING ACCESS

The telephone ring PASSWORD is used to start the ringing process on the repeater for incoming calls; also see S-Command 71,
incoming call mode. This password is only used in S-Command 71 modes 3 and 4. The controller will answer the telephone
and incoming ringing and provide an answer message to the caller. After this message, the ring password is used to start the
ring process on the repeater to let someone listening to the radio know that a caller is waiting on the telephone. The factory
default password is 343 and can be changed to another password, from 1 to 6 digits long. “C” is the only digit that cannot be
used in this password. Avoid using “A”, “B” and “D” as these digits are not typically available on standard telephones. For

S-Cmd 62 DEFINING USER COMMANDS

S-Command 62 provides the means to create a user commands. There are four types of User Commands. Each type is
discussed below. T o clear a User Command name, send S-Command 62 followed by the command number you want to clear.

When the controller is locked (User command mode) and a user sends a command, the controller compares this incoming
command with the list of commands defined by this S-Command. The controller compares the length of the command and the
digits in the command, looking for a match. If the controller finds a match, it will look up the macro start line and then execute
the macro.

The types of User Commands are:

Standard:

total number of digits must match. If there are any extra digits in the command, the command will be rejected.

Telephone:

the telephone number to be automatically dialed. A standard User Command does not provide for appended digits. The macro
that is created for the telephone off-hook function should always include the off-hook S-Command 82 in order to work
correctly. The on-hook command is not required to be a telephone type user command. Use the Standard user command type
for building on-hook commands.

S-Commands:

renamed as “User Commands”. These created user commands allow appended digits after the command name, digits which are
passed along to the S-Command to which it points. Specify the number of the
S-Command you want to execute instead of the number of the macro start line as used in the Standard type User Command.
The S-Command value should include one leading zero. Example: S-Command 05 should be entered as “005”.

Wildcard:

to one or more S-Commands within the macro called by that wildcard command. Multiple groups of digits can be passed to
multiple S-Commands within the macro. The wildcard command’s digits will replace all instances of "Bxx" in the macro with
the digits from the user command. Within the Bxx wildcard, the first “x” is an index and defines the first position of the
wildcard data to use. The first character in the wildcard data is numbered as character zero (0). The second “x” is the number
of characters to be used from the wildcard. A Zero (0) placed here will cause the controller to use all the remaining characters
in the wild card. See the following example:

Define a wildcard command with “14” as the name of the command. This command will set the frequency of a 2-meter remote
base radio. When the user enters “14652” the controller will find “14” as a user command, and define 652 as the wildcard data.
In the macro called by User command 14, include the following S-Command: (91 12 14 B00 #2).
The “91 12” will set the receive frequency. The “14” defines the first two digits in the frequency. The “B00” tells the
controller to use all the characters in the wild card. The “#2” sets the transmitter to simplex. You could create a “14*” and
“14#” command to set plus and minus offsets. The end effect is the same as programming S-Command “91 12 14652 #2”.

In this example, define a wildcard command with “*5” as the name of the command. This command will send a key-down
transmitter time to a controller attached to the auxiliary buss. When the user enters “*5355” the controller will find *5 as a user
command, and define 355 as the wildcard data. In the macro called by User command *5, include the following
S-Command: (A B01 05 B10). The “A” will address a controller on the auxiliary buss. The “B01” will get the first (number 0)
character “3”, and append it to the “A” part of the command, defining the third controller on the auxiliary buss as the one to
which the S-Command is sent, (A3). The “05” S-Command will set the TX on for “x” time. The “B10” will tell the controller
to use all the remaining digits (55) starting with the digit numbered 1. The end effect is the same as programming S-Command
“A3 05 55”

Standard user commands must match exactly with a command in the stored list. Both the digits themselves and the

Telephone dial commands provide for extra digits to be appended to the command. These extra digits are used for

This type is used to define a “User System Command”. User System Commands are S-Commands that are

Wildcard commands allow extra digits to be included within the command. These extra digits can then be passed

S-Cmd 63 MACRO EDITOR, SET STARTING LINE NUMBER POINTER

Macros are one or more S-Commands strung together. Messages are also stored in the same memory area as macros. To build
a macro or message, you must first tell the controller where the macro or message will start (Macro Start Line). Then enter
S-Co mmands (S-Command 64) or CW-Comman ds (S-Command 31) into the macro data memo ry. This command is used to set
the macro start line pointer. The controller will keep track of the exact position in the macro data memory as you enter data.
There are 999 starting lines in the macro data memory.

PARAMETERS: Macro start line 000 through 99 9

S-Cmd 64 MACRO EDITOR, INSERT S-COMMANDS

The system memory is used for both macros and messages. This memory is organized with 999 lines of data storage with each
line consisting of 24 digits. Once you have set the macro start line pointer (S-Command 63), you can begin to enter
S-Commands into the macro data memory. One or more S-Commands can be strung to ge ther and the data is allowed to
continue through additional lines until the end of the macro is reached. When you enter S-Commands and their date into
memory, the controller will add a “C” so as to separate the S-Commands. It is important to know how the controller stores
data, so that you can allow for this digit when keeping track of memory usage. The last entry of your macro is an end of macro
character, “D” which is used to terminate the macro. Send “64” without data, and the controller will put a “D” into the macro
data memory for you. The controller uses a “C” for a command separator and “D” for end of macro. You need to allow space
for these digits when planning your macro data usage. See the default table below for an example.

S-Cmd 65 CONDITIONAL STATEMENTS (IF / THEN / ELSE)

This command is used to test system variables in a conditional statement and branch based on a true or false outcome. The
conditional statements have various parts. Within these parts, the conditional statement will test the EXPRESSION part THEN
execute the STATEMENT part that follows the EXPRESSION if TRUE, ELSE the first STATEMENT is skipped and the
second STATEMENT is executed. The macro terminator (S-Command 64 or "D") is used to separate the first STATEMENT
from the second. A STATEMENT is nothing more then a group of S-Commands.

IF EXPRESSION THEN STATEMENT ELSE STATEMENT
Or:
IF EXPRESSION BIND EXPRESSION THEN STATEMENT ELSE STATEMENT

You can even nest conditional statements, but the controller will completely terminate the macro or conditional statement once
the first macro terminator is encountered after a group of S-Commands.

IF The S-Command itself (65).
EXPRESSION The expression has up to 4 parts as follows
Variable An internal value that is tested in the conditional statement. See the tables on the following two pages for a

list of all variables.
Index Some variables must be indexed. Example, the enabled tone decode is indexed by the actual tone number.
Operation Compares the variable to the reference. (Equal, Not equal, Less than, Greater than) The outcome of the

compare is either true or false.
Reference This is the value that is compared to the variab le. When compared, the outcome will be either true or false.
BIND Binding is optional and is used to bind multiple expressio ns together. Binding is a logical OR/AND of two or

more expressions. The only limit in the number of items that you can bind is a total of 34 characters.
THEN The THEN part of the macro is executed because of a true outcome of the expression. This part includes all

S-Commands between the conditional statement and an end of macro terminator (S-Cmd 64, “D”).
ELSE The ELSE part of the macro is executed because of a false outcome of the expression. This part includes all

S-Commands following the first macro terminator (S -Cmd 64, “D”) though the next macro terminator.

S-Cmd 66 READ / WRITE / PUSH / POP SYSTEM DATA

The RI-300 controller stores all of its system data on EEPROM, a non-volatile memory. It also has two temporary RAM
memory locations for storing this same system data. The first of the two RAM locations holds the systems data that is used in
operating the controller. When you first turn on the power, the controller will copy the EEPROM data into this first RAM data
location. You can modify this RAM data and then by using the WRITE command, save your changes to the EEPROM. Or,
you may have system RAM that has been modified, and you can READ the EEPROM data back into the RAM, returning the
controller to a normal state. The second RAM data location is used like a stack. You can copy the first RAM data to the
second with the PUSH command. Or, copy the second RAM location to the first with the POP command. This will allow you
to save a current system configuration, make a
temporary change, and then recall the former settings.
When power is first turned on, the controller will copy
the EEPROM to both RAM locations. Only
S-Commands that are labeled with “STORAGE:
RAM/EEPROM” have data that is affected by this
command.

(lock the controller) and save your changes to the EEPROM or recall the old data from the EEPROM, not saving your changes.
If no S-Commands are executed for 5 minutes, a timer will automatically lock the controller for you and discard your changes.

S-Cmd 70 TELEPHONE OUTGOING CALL MODE

This command is used to set up how the controller operates when making outgoing telephone calls. Outgoing calls operate
under the rules determined by modes 0 through 6. If you are operating with a full duplexe d mobile and using mode 2, you ca n
listen to the caller while you are talking on the repeater. In mode 3, other people on the repeater will not be able to hear you
talk to the caller. Mode 4 is the same as mode 3 except that a tone is added to the repeater TX when you are transmitting to the
caller.

S-Cmd 71 TELEPHONE INCOMING CALL MODE

This command is used to set up how the controller operates during incoming phone calls. In all modes, the controller will not
act on incoming rings until the ring delay counter (S-Command 75) has expired.

• Mode 0: All ringing will be ignored.

• Mode 1: The repeater will begin ringing out on the repeater transmitter after the ring delay (S-Command 75) has expired

and each time the incoming call rings but not more than the ring limit (S-Command 76).

• Mode 2: The controller will not go off-hook until after the ring delay (S-Command 75) has expired. At this time, the

controller will go off-hook and start to ring the transmitter for the total number of rings set by the ring limit (S-Command

76). During both the ring delay time and the ring limit time, you may enter the telephone control access password to put
your call in the telephone control mode. While in this control mode, your telephone audio is not connected to the repeater
transmitter. In control mode, you may begin sending user commands or use the system password to access the
programming mode.

• Mode 3: Operates the same as mode 2, but the controller will play the phone answer message when it goes off-hook. The

caller must enter the ring password (S-Command 56) to start telephone ringing on the repeater transmitter.

• Mode 4: Operates the same as mode 3, but a three digit CTCSS tone or DCS code number is additio nally required on the

end of the ring password. You can also add up to an 8-digit DTMF string on the end of the CTCSS tone number. Mode 4
can be used for selective calling to a radio that employs a CTCSS tone decoder or detects DTMF tones, respectively.

• Mode 5: Is auto answer. The controller will go off-hook and connect the telephone audio to the repeater transmitter after

the ring delay counter expires.

• Mode 6: Operates the same a mode 3, but the caller has access to the user commands in command group 8 without using

the control password. Use this mode to customize the incoming call mode.
