SECTION 1 INTRODUCTION

What is the RI-1

The RI-1 is a standalone repeater controller that can be connected to an auxiliary buss to communicate with other RI-xxx controllers. Other then the difference in mechanical form, the functions and features of the RI-1 and PE-1 are the same. This manual will cover both controllers. Areas where there are differences between the controllers will be clearly pointed out.

What is the PE-1

The PE-1 is a standalone repeater controller that is installed inside the RI-300 controller chassis. It can communicate with the RI-300 controller over the auxiliary buss. Other than the difference in mechanical form, the functions and features of the PE-1 and RI-1 are the same. This manual will cover both controllers. Areas where there are differences between the controllers will be clearly pointed out.

Overview

Your controller represents the latest technological advances in repeater control systems. The RI-1 utilizes a microprocessor design, which provides all the control functions for a single repeater or link on a single printed circuit board. 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-1/PE-1 is easy to set up and use.

Once you are familiar with the macro command system, you can customize your user commands and messages. We recommend that you read sections 1 through 3, 7 and 8 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-1/PE-1's many features.

Feature List

The following are features of the RI-1 and PE-1 controller:

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

• Auxiliary audio buss. Connect to other controllers for links, remotes and multiple repeater connections.

• The receiver audio level, auxiliary audio level and tone generator level may be remotely adjusted by radio.

• A selectable low pass audio filter is provided to remove adjacent channel splatter.

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

• A dual tone generator provides both level and frequency control.

• User programmable inputs and outputs exist for external sensing and control.

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

battery.

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

The RI-1 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 RI-1 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.

SECTION 2 QUICK START

This section will cover the basics of installation and programming of your RI-1. You may also need to review section 4 or 5 for more details on connecting your RI-1 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-1

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

1. RI-1 or PE-1 Repeater controller board with mating DB25S connector.

2. User manual on CD.

3. Mounting hardware.

MOUNTING THE RI-1 REPEATER CONTROLLER

1. An optional single controller chassis is available. Mounting holes are provided for the repeater controller board within the

enclosure.

2. The repeater builder can mount the RI-1 repeater controller in any enclosure of his choice. The enclosure that you select

should be strong enough to mechanically protect the contents. The enclosure should be made of metal with good shielding properties. We do not recommend the use of a plastic enclosure in a RF environment. Mount the RI-1 unit with #4-40 standoffs on the mounting surface.

3. Avoid installing the RI-1 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-1 repeater controller is very easy to interface with your repeater. Before you continue, 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 PE-1, you should go directly to section 5.

1. +12 Volts DC power source, J1 Pin 5. (Only on the RI-1, the PE-1 gets its power from the RI-300)

2. DC power ground, J1 Pin 21, J1 Pin 5.

3. Receiver audio, J1 Pin 2.

4. Receiver NSQ (Squelch), J1 Pin 6.

5. Receiver TSQ (CTCSS), J1 Pin 7, Optional.

6. Audio return and/or shield, J1 Pin 15.

7. Transmitter audio, J1 Pin 3

8. Transmitter keying circuit (PTT), J1 Pin 4.

SETTING AUDIO LEVELS

Adjusting the levels in your controller is very important, in order to achieve proper decoder operation and avoid clipping and distortion. See section 6 of this manual for more complete details on correct adjustment of the audio levels.

Receiver Gain

1. Generate a 1000 Hz tone at 5 kHz of deviation on the repeater input.

2. Using an AC volt meter, adjust VR2 for 0.77 volts AC RMS on U6 pin 7.

Signal Polarity

Verify that the NSQ, TSQ and PTT signals are of the correct polarity. This can be viewed with the LEDs on the circuit board or from the programming software. To change any of these signal polarities, use System Command 00 or the programming software (PS-3). See section 6 for more details on this subject.

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 3 KHz 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 adjusted by the single turn pot, VR1. If you are operating the controller as a repeater, you will have to issue User Command “*1” to set the controller into a repeater mode.

OPERATION

Once you have connected your controller to a receiver / transmitter and adjusted the audio, you should then confirm its basic repeater or link 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.

INITIAL SETTINGS

You are now ready to set the Station ID. This subject is not easily covered in a single paragraph. Therefore, we recommend that you go to section 8 of this user manual for this procedure.

SECTION 3 PS-3, PROGRAMMING SOFTWARE

An optional programming software and cable package is available. This software is designed to run under Windows 95/98, ME, NT, 2000 and XP. The software will allow you to read, change and save all parameters within your RI-1 controller. You can even load a 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. With the RI-1, use the auxiliary connector J2. With the PE-1, use the connector on the front of the RI-300 controller labeled “MIC/PROG”. 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.

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 PS-3 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 upload 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 "RI1.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 new file name. When making changes to your controller’s 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 current file.

FLASHING the CONTROLLER’S PROGRAM

As new features are added and revisions are made to the RI-1, program updates are made available on our web site www.pacres.com. You can locate these changes under the RI-1 firmware and software page. 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 controller’s program memory.

1. Connect your computer to the controller using the programming cable. Run the PS-3 Programming Software.

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 text just below this group’s title will show the type of controller that the software has detected. 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 “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. At the bottom is a “File Description” group. This title will also show the type of controller file. This group is for your use to describe the actual file you are working with.

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.

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.

SECTION 4 INSTALLATION (RI-1)

If you are installing the PE-1 into the RI-300 chassis, you can skip to the next section.

This section will cover connecting your RI-1 to your repeater in detail. To ensure a successful installation, please follow these few simple steps.

1. Review this section completely and plan you repeater interface before you start making connections.

2. Review section 6 of this manual for detailed information on making audio level adjustments.

The diagram on the right is an end view of the radio interface connector on your RI-1. Use the supplied DB-25S female connector for making all connections to the controller.

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-1 was designed to operate with both emphasized and flat audio response from the repeater receiver and transmitter. This means that you can bypass the de-emphasis and/or pre-emphasis stage in the radio when possible. This leaves all of the emphasis filtering in the user’s radio. The RI-1 will interface to emphasis audio when needed.

The RI-1 controller does include a low pass filter that rolls off the very high audio frequency content to prevent adjacent channel splatter. 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.

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 possible. On the other hand, do not let the audio signal get large enough where clipping occurs in any stage of the controller, the receiver, or the transmitter. See section 6 for more details on adjusting the audio levels in the controller. Consider and practice the above and you will have repeater audio that you and your repeater users will be proud of.

POWER SUPPLY CONNECTIONS (Pins 5 and 21)

The RI-1 operates on 12 volts DC nominal. The DC source voltage must be between 10 and 15 VDC. The controller typically draws less then 40 ma without the status LEDs on. Connect the +12v to J1 pin 5. Connect J1 pin 21 to ground or the 12v 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. The RI-1 repeater controller connection to the power supply must be over-current protected. Use of a 1/8 ampere fuse should be the largest capacity considered in your installation.

REPEATER RECEIVER AUDIO CONNECTION (Pin 2)

Connect the receiver discriminator audio when ever possible to pin 2 and the receiver ground or audio return to J1 pin 15. If the discriminator output is not available, you can connect to a de-emphasized output and set correctly select this type of audio. It is not advisable to connect the controller to the speaker leads. Most radio amplifiers have significant audio shaping and may lead to loss of audio response. If you are not familiar with the repeater receiver, get assistance from someone knowledgeable on the subject or contact our factory for support. For best performance all audio connections should be made with a shielded cable. The controller’s audio path has a flat frequency response from 30 Hz through 3500 Hz. When interfaced properly to the repeater receiver and transmitter, the controller will provide superb audio characteristics.

NSQ and TSQ Input (Pin 6 and 7)

The RI-1 does not have its own squelch or CTCSS decoder. The radio or audio source must provide these functions. Connect the output of the radios squelch circuit to pin 6 (NSQ) and the CTCSS decoder, if used, to pin 7 (TSQ). These inputs are 0-5 volt logic input with a 22K pull-up resistor. Then can except a logic or open collector source. They also can be programmed for active low and active high signals. If you are connecting to a device other then a radio, you can use the (NSQ) input to signal the RI-1 when a signal is available to process.

REPEATER TRANSMITTER AUDIO CONNECTIONS (Pin 3)

Use a direct FM type modulator whenever possible. The RI-1 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 15. If a FM modulator without pre-emphasis is not available, the RI-1 can be jumped to drive a phase modulator or modulator with pre-emphasis. Do this by installing jumpers on JP4 pins 2-3. For FM modulation, install a jumper on JP4 pins 1-2. See section 16 for more information on this subject.

REPEATER TRANSMITTER PTT OR TRANSMIT KEYING CONNECTION (Pin 4)

The RI-1 repeater controller keys the transmitter at the required times. WARNING - As with all repeater controllers, this 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 a maximum of 120 ma of current. Connect J1 pin 4 to the repeater transmitter PTT.

DIGITAL INPUTS (Pins 16 and 17)

The RI-1 has two digital inputs on board 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 11, S-Command 45 for additional information on programming these inputs. These inputs are located on J1 pins 16 and 17. See the connector diagram on the previous page.

Page 11

Pacific Research Solutions RI-1 and PE-1 User Manual

DIGITAL OUTPUTS (Pins 8 and 9)

The RI-1 has two digital outputs on board and is currently expandable up to ten, whose states can be modified by S-Commands. Each of the two outputs can be individually commanded or forced into the high or low logic state. These outputs are open drain FET transistors and can sink up to 120ma each. There are no pull-up resistors on these outputs. If pullup resistors are needed, they must be provided by the user supplied interface. These outputs can sink current from a voltage sources as high as 24 volts DC. Using S-Commands (or macros that are composed of S-Commands), each output may be turned on or off. See Sections 11 S-Command 46 additional information on programming these outputs. These outputs are located on J1 pins 8 and 9. See the connector diagram on the previous page.

+5V Output (Pins 1)

This is a low current +5V supply output. This output can be used to power an interface circuit external to the controller. Do not draw more then 25mA from this output.

SERIAL DATA (Pins 18 through 20)

These signals are reserved for digital output expansion. This feature is to be added at a later time.

RADIO DATA (Pins 10 through 14)

These signals are reserved for serial communication to various radios. This feature is to be added at a later time.

RS-232 DATA (Pins 22 through 25)

These signals are used to communicate to various radios and EchoLink. See linking section for more details.

SECTION 5 INSTALLATION (PE-1)

The PE-1 (Port Expansion) board adds various features to the RI-300 controller. The RI-310 controller (Discontinued) cannot use the PE-1. For additional details, see the schematic in section 16. These features include:

• 1 full duplexed repeating audio port (input and output)

with level adjustments.

• 2 digital inputs (5V logic). These bits are accessed via S-

Command 45

• 2 digital outputs (open drain). These bits are accessed via

S-Command 46.

To install your PE-1, use the following steps.

1. Turn off power to the repeater and controller.

2. When working on your controller, use procedures to assure no static discharge occurs through the controller or PE-1.

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 PE-1 into this header, making sure all pins align. The DB-25 connector on the PE-1 should align in the same direction as the radio interface connector.

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

6. Re-install the analog board and PE-1 into the chassis, installing the 4 mounting studs on the 2 connectors.

7. You are now ready to use your PE-1.

SECTION 6 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 controller to help you through this process.

Warning: Refer to section 8, Initialization procedure. When a full controller initialization is performed 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.

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

1. When entering your password for the first time, make sure the NSQ, TSQ and DTMF status LED’s are operating properly. Most of the startup problems will relate to logic levels or audio level too low, too high, too much DTMF twist and/or audio distortion. The RI-1 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 at a time, checking all DTMF tone digits, letting the LED light go out after each one. Then test the next tone, confirming that all YOUR tones are being properly decoded.

4. If you send your password multiple times and receive an “ERROR” telemetry message, the controller may already be unlocked and in programming mode.

SETTING RECEIVER INPUT GAIN (R3)

Setting the receiver input gain may be the most important adjustment in the controller. For the internal decoders (DTMF) to work properly, you need to set up the receiver input audio level correctly. The receiver input audio level setting is a manual adjustment. Please use the follow the procedure:

1. Apply the 12 VDC power source. Confirm that all 4 LEDs flash on for about 1 second. After power up, some LEDs may remain on. Do not be concern at this point as we have not completed adjusting your controller.

2. Transmit a carrier on the repeater’s input channel. Did the yellow NSQ light come on? Do not be surprised if the NSQ LED did not come on or is already on, as we have adjustments to make before the NSQ logic will work correctly.

3. Generate a 1000 Hz tone at 5 kHz deviation on the repeater input.

4. Using an AC volt meter that has high frequency response, probe U6 pin 7 for 0.77 volts AC RMS. Use the supply ground for your negative connection.

5. The receiver input level is adjusted by the single turn pot VR2.

SELECTING NSQ, TSQ and PTT SIGNAL POLARITY

The polarity of the NSQ, TSQ and PTT signals are selectable. If you do not have the programming software to make this adjustment, you can still send DTMF commands to the controller, but you will have to wait for the inter-digit timeout to expire for the command to execute. To adjust these signal polarity, unlock the controller with the default password “123456”. You may not hear an acknowledgment because we have not adjusted the transmitter lever at this point. Next send System Command 000x, 001x and 002x to change the polarity of these signals. See section 11 for more details on this System Command. You must finish with System Command 691 to lock and save your changes.

You can also use the programming software (PS-3) to adjust these values. Click “System” and “System Setup”. See the group under “Input Signal Polarity” in the figure to the right. After you have made your changes, click the “Send” button to update the controller.

SELECTING RECEIVER EMPHAISIS TYPE

If you are interfacing directly to the receiver’s demodulator, you will want to disable the controller’s receiver emphasis stage. For all other types of audios interface, including VoIP, you will want to enable the controller’s emphasis stage. This is done with System Command 003x. Use System Command 0030 (Factory Default) to disable the emphasis stage or use System Command 0031 to enable the controller’s emphasis stage. You can send this command over the AIR with DTMF or you can use the programming software (PS-3). If sending the command to the controller with DTMF, do not forget to unlock and lock/save your data. If using the programming software, click “System” and “System Setup”. See the group under “Audio Response” in the figure to the right.

SELECTING LOW PASS FILTER

A selectable low pass filter is provided to allow for interface with various types of modulation standards. This filter is used to prevent adjacent channel splatter. If you are operating on 20KHz or more channel spacing, we recommend you use the 3500Hz cutoff selection. If you are operating on 15KHz or less channel spacing, we recommend that you use the 2500Hz cutoff selection.

You can adjust this filter over the air using S-Command 03 or the programming software (PS-3) Click System and System Setup. See the group under “Audio Response” in the figure to the right.

FINAL ADJUSTMENT OF RECEIVER GAIN

Fine adjustments to the receiver gain can be made from over the air using S-Command 02 or the programming software (PS-3) Click System and System Setup. See the group under “Receiver Gain” in the figure to the right.

SELECTING TRANSMITTER EMPHAISIS TYPE

If you are interfacing directly to a true FM type modulator, you will want to disable the controller’s transmitter emphasis stage. This is accomplished with a jumper (JP-4) on the circuit board. See the figure to the right. Pin 3 is located in the lower corner of the board. For modulators that are true FM and without emphasis, place jumper on pins 2 and 3. For all other types of modulators and audio interfaces, including VoIP, you will want to place the jumper on pins 1 and 2.

ADJUSTING THE REPEATER TRANSMITTER MODULATION

After hooking up the repeater transmitter audio and the repeater PTT keying circuit per Section 4, you will need to adjust the repeat TX audio 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 adjusted with pot, VR1. If you operating the controller as a simplex link or remote base, enable the audio path from the source controller using System Command 35. Transmit audio on the source controller’s input and adjust VR1 for the correct level.

SETTING UP THE RI-1 AUXILIARY INTERFACE CONNECTOR

If you are working with the PE-1 or you do not have the RI-1 controller connected to another controller, you can skip this sub section.

The RI-1 does not support a full cross point switch on the auxiliary buss. This means that if you are going to connect the RI-1 to another RI-1 or RI300, you will use jumper blocks need to select the input and output channels on the auxiliary buss. Use the diagram to the right to assist on jumper placement of each channel.

When deciding on setting jumpers, you must first decide on what channels you will be using. If you will be connecting an RI-300 to the RI-1, the RI300 is default to output on channel 1 and the RI-1 is default on channel 8. You would then install a jumper on pins 1 and 2 so that the RI-1 can listen to the RI-300. You then place a jumper on pins 15 and 16 so that the RI300 can listen to the RI-1.

All jumpers are placed in combination of one for AUX-IN and one for AUX-OUT. You should never place multiple jumpers for the AUX-IN or AUX-OUT.

After you have placed the jumpers, you then use System Commands 34 and 35 to enable and disable the input and output. You can also use the programming software (PS-3) to adjust these default values. Click System and Auxiliary Setup.

SECTION 7 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 “NSQ” LED turning on and off when you key and un-key. If you have enabled the Repeater Port Mode, System Command 01, 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 yourself on the output of the repeater.

SYSTEM STATUS INDICATORS

The system status LED indicators will display the current status of the controller. During the controller power on self-test, the RI-1 will turn on all of the status LEDs for about 1 second. These LED’s are located in the middle of the circuit board, see the figure below.

INDICATOR DESCRIPTION / FUNCTION

NSQ Noise Squelch; indicates when a signal is present at the receiver. TSQ Repeater Tone Squelch indicates when a CTCSS (Continuous Tone Controlled Squelch System) or DCS

(Digital Coded Squelch) has been enabled in the repeater tone panel and is present at the receiver. PTT Push-To-Talk; indicates when the controller is keying the repeater transmitter. DTMF Dual Tone Multi-Frequency; indicates when the controller is decoding DTMF (Touch-Tones).

RI-1 Controller PE-1 Port Expansion

DTMF COMMAND INPUT

Dual Tone Multi Frequency (DTMF) is typically used in the telephone system for dialing. The RI-1 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. CW “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.

TELEMETRY MESSAGES

Telemetry or messages are sent from the controller to you in response to a repeater status or function. There are primarily four types of messages.

1. The station ID.

2. Courtesy messages, which occur after you un-key.

3. System functions (OK, ERROR).

4. User programmable messages. These maybe CW messages that are created by the system operator.

Any of the controller’s messages may be modified with S-Commands 30 and 31. The controller comes pre-programmed with default messages in response to any one of the following events:

EVENT DESCRIPTION

Repeater Courtesy A courtesy message is sent after each user un-keys to let the other users know when the time-out

timer has been reset and that it is OK to continue talking. This message occurs when the time

clock has been set. Auxiliary Courtesy This replaces the courtesy message when the received signal is weak or noisy. Station ID This is the system identification, can be either CW or Speech. The factory default is CW

“HELLO”. This ID is sent periodically as required by the FCC. Function Error Generated in response to an S-Command that the controller did not understand. Function Complete Generated in response to an S-Command the controller understood and executed.

It should be noted that when the controller is executing a macro, the function complete or function error is in response to the S-Commands within the macro. If you get a function error when controlling your system with a user command, you have an S-Command with an error within the macro.

INITIALIZATION PROCEDURE

There is only one method of re-initializing and returning to the factory default data. Default data for each of the S-Commands is listed in section 11 and the System Command Table at the end of this manual. To initialize the RI-1 data, use the following procedure:

1. Unlock the controller with DTMF or use the programming software “Send S-Cmd” dialog.

2. Send 5986 to the controller.
