INTRODUCTION
Your controller represents the latest technological advances in repeater control systems. The RI-200 utilizes a microprocessor design providing all control functions for a single repeater on a main printed circuit board 3½ by 6 inches and a sub telephone interconnect board, 1½ by 3½ inches. The RI-200 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. The microprocessor and power supply are constan tly monitored by a "WATCHDOG TIMER" and “POWER SUPPLY SUPERVISORY CIRCUITS” that maintain the operational integrity of the system. The RI-200 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. Connecting to the telephone is provided with a RJ-11 telephone jack.
Once you are familiar with the macro command system you can customize your users, messages, and schedulers. We recommend that you read sections 1 and 2 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-200's many features.
The RI-200 repeater interconnect has the following features which together are not available in any other repeater controller in the industry:
Full duplex telephone interconnect with a self-balancing hybrid.
•
Transmit audio level, squelch level, CTCSS level and telephone level potentiometer adjustments are radio remotely
•
adjustable. On board squelch circuit. You do not have to add in someone else’s circuit. It’s SmartSquelch, An intelligent
•
microprocessor controlled squelch and it’s fast. On board CTCSS decoder an d en coder. You do not have to add in an extern a l decoder. It’s clean an d cost effective.
•
The decoder and encode are remotely programmable. Multiple CTCSS tone decoded tone panel features are provided. A selectable sub audio reject filter is provided, to remove the received CTCSS sub-a u d io tone from being repeated.
•
Optional DCS (Digital Controlled Squelch) decode and encode is available with the same features at CTCSS.
•
DTMF tones maybe passed, muted, or regenerated.
•
User programmable inputs and outputs.
•
User programmable event scheduler. Command can be programmed to execute automatically.
•

•
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 feature desired.
•
The RI-200 provides excellent audio quality. With proper consideration when interfacing th e 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 d iscriminator output must be connected to the RI-200 audio input in order for the squelch circuit to function properly and to provide excellent audio.

What is a RI-210?
Play” component for the Yaesu/Vertex VXR-5000 repeaters. This manual was written around the RI-200 repeater controller, which is a generic version, designed to interface with any repeater. Some features such as digital inputs and outputs are available on the board, but because Vertex repeater connectors are specialized, these connections are not directly available on a connector. If you have an application that requires these inputs and/or outputs, you can access them by making connections directly to the circuit board.
The RI-210 is one model in a series of RI-200 repeater controllers designed specifically as a “Plug-N-

GETTING STARTED
1.0 QUICK START
This section will cover the basics of installation and programming of your RI-200. You may also need to review section 2 for more details on connecting your RI-200 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.
1.1 UNPACKING THE RI-200
Inspect the carton for the following contents and if any of the items that you have ordered are missing or damaged, notify your RI-200 dealer or th e factory that shipped the un it t o you.
1. RI-200 Repeater controller board with mating DB15S connector. RI-210 does not come with the DB15S connector.
2. DB25 Connector used only with the RI-210.
3. UM-200 Printed user manual.
4. IC-200 Optional inter conn ect cable for connecting to another RI-200.
1.2 MOUNTING THE RI-200 REPEATER CONTROLLER
Skip to section 1.3 if you are installing a RI-210
1. An optional single controller enclosure or a standard 19 in ch wide 1-3/4 inch high rack mounted enclosure is available. Mounting holes are provided for the repeater controller and for the front panel LED status boards within the enclosure.
2. The repeater builder can mount the RI-200 repeater controller in any enclosure of his choice. The enclosure tha t you selected should be strong enough to mechanically protect the contents. The enclosure should be made of metal with good shielding pr operties. We do not recommend the use of a plastic enclosure in a RF environm ent . Mounti ng the RI-200 is accomplished by drilling four holes and mounting the unit with #4-40 standoffs.
3. Avoid installing th e RI-200 in the following places.
Directly above a transmitter or power amplifier because of heat and RF considerations.
•
Directly above an y powe r supplies because of heat and 60 Hz coupling into the audio circuits.
•
1.2.1 INTERFACE YOUR RECEIVER AND TRANSMITTER
The RI-200 repeater controller is very easy to interface with your r epeater. Before you continue, you need to make the following connections. All connections are covered with greater detail in section 2 of this manual. Once you have finished connecting your RI-200 to your repeater, you can contin ue with section 1.4 of this man ua l.

1.3 INSTALLING THE RI-210 REPEATER CONTROLLER
Skip to the next section if you are not installing the RI-210 into a VX-5000 repeater.
1. Start by removing the four screws holding the top cover on the Vertex repeater.
2. Install the Vertex programming cable and a dummy load on the TX ANT connector.
3. Connect power to the repeater and run th e Vertex programming software that came with the vertex repeater.
4. Select the “CLONE” mode and use “F3” to copy the current repeater configuration to the program.
5. Go into the “Timer” menu and disable all of the “REPEATER’ and “BASE” timers.
6. Go into the “Setup” menu and set the “Mode” to “Duplex”, the “Beep” to “Disable” and “Hang” to “Quiet”.
7. Because the RI-210 has its own CTCSS/DCS decoder, you will need to disable the Vertex CTCSS decoder. Last, go into the “Option” menu and disable the Vertex CTCSS tone decode. In some older models of the repeater, you will need to unplug the optional Vertex CTCSS decoder assembly.
8. Save these new values to the repeater by using “F4” key.
9. Disconnect the power and programming cable from the repeater
10. Place the RI-210 in the slot between the r eceiver an d the exciter. The telephone ja ck s hould be loca ted on the side closest to the power supply or RF power amp.
11. The mounting holes in the RI-210 should line up with the mountin g t a bs in the Vertex repeater. The RI-210 is held in place by the two screws that were supplied. The bottom of the RI-210 circuit board should line up with a card edge bracket in the bottom of the Vertex repeater.
12. There are four cables used to connect the RI-210 controller to the Vertex repeater. On t he Vertex Control 2 board, you need to unplug the two pin connector plug J2007 and plug it into the two pin connector on the RI-210.
13. Unplug the four pin connector J2006 and plug it i nto the four pin connector on the RI-210.
14. Follow the diagram below. From the Vertex Control 1 board you need to unplug conn ector J1002. This connector has 8 wires going to it and the yellow wire is pin 1. Remove pin 6 contact from the housing. This can be done by using the tip of a x-acto knife to lift up on the plastic finger that holds the contact in the housing and remove the contact.
15. On the 8 pin cable supplied with the RI-210 controller, you will notice one of the housing is missing a contact at pin 6. Take the contact that you just removed and plug it into this housing.
16. Plug your connector housing with the missing contact, into the connector on the RI-210 marked “TO J3002.
17. Plug in the other conn ector housing with a free wire and contact in t o the connector on th e RI-210 marked “T0 J1002”.
18. Plug in the last connector where you just installed a contact, into the Vertex controller where you removed the 8 pin cable in step 14.
19. Un-plug the 3 pin connector on th e Vertex Contr ol 1 board labeled “J1010”.
20. Remove the center contact from this housing. This can be done by using the tip of an x-acto knife to lift up on the plastic finger that holds the contact in the housing and remove the contact
21. Plug the extra wire and contact coming from the RI-210 8 pin connector into the center position of this 3 pin plug. Reinstall the 3 pin plug into the Vertex Controller.
22. Insulate the last free contact so that it will not short out on anything.
23. On t he Vert ex repeater “ACC” connector, connect pin 13 “base” to pin 1 “g round”, use the suppl ied DB25 connector.
24. Because the RI-210 is designed to function directly in the Vertex repeater, all input and output audio levels have been preset , however the receiver and transmitter audio levels and squelch gain may need minor adjustments. See Section 3.4 for details on this procedure.
25. Use the potentiometer on the top of the “TX UNIT” to adjust the DCS deviation.
26. Because the RI-210 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.
The repeater controller and telephone interconnect is now functional with the factory default commands, features, and messages. This allows operation of your new repeater within minutes of installation.

To utilize all the features, macros, and messages the repeater owner can customize a RI-210 by sending commands over the air or telephone. This manual should be completely understood to fully enjoy all of the RI-210’s power and features.
1.4 SETTING UP YOUR REPEATER CONTROLLER
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. You will first hear a CW “OK” and then followed by the default CW ID “HELLO”. The system LED shoul d be the
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. Th e SYS, AUX, DT MF 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.
When you are sending commands via DTMF, the controller is always in one of the 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. When the controller is in this mode you will hear an ascending 4 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 descending 4 tone (weak signal). When you send the programming password, the RI-200 unlocks and will switch to a programming or System Command (S-Command) mode. When the controller is in this mode you will hear 2 tone courtesy each time you un-key with a full quieting signal. Again in this mode if your signal is not full quieting, the courtesy will change to a descending 4 tone.
only
LED on.
Each time you send commands to the RI-200, you will get one of 3 responses. First, if you send any valid command without errors, the RI-200 will respond with a CW acknowledgment message “OK”. This message is lower pitch and h as the rhythm of “dah dah dah dah dit dah”. Second, if you send an S-Command with an error or a user command that has an error in its programming, the RI-200 will respond with a CW error message “ERROR”. This message is high pitch and has the rhythm of “dit di dah dit di dah dit dah dah dah di dah dit”. Third, if you send an invalid command, the RI-200 will not respond with any message.
When you are programming your RI-200 over the air, it is important to have a full quieting signal to the repeater. As with a noisy signal, digits can be missed and the result of the command may not turn out the way you planed. The following is a list of some common problems p eople h ave:
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 looks like some other valid command. If you move in and out of a 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-200 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. Note that if you are in the S-Command mode after 5 minutes have past without sending a command, the controller will lock itself. When this happens, you will hear a CW “OK” without sending a command.
Page 8
1.4.1 DEFAULT USER COMMANDS
The controller comes programmed with some default User Commands. See section 5 for details on changing the command names or the commands themselves. You can use these commands only when the controller is locked.
#1 Repeater (system) OFF. *1 Repeater (system) ON and with CTCSS/DCS required to access repeater. *2 Repeater (system) ON and with only a carrier needed to access repeater. *3 Repeater (system) ON and with squelch open. #4 Repeater CTC SS t on e encode OFF. *4 Repeater CTCSS tone encode ON. #5 DTMF mute OFF. *5 DTMF mute ON. #6 Carrier delay OFF. *6 Carrier delay ON. *7 Answer Telephone only if ringing. *8 Telephone off-hook, simplex. You can include the telephone number with this command. *9 Telephone off-hook, duplex. You must include the telephone number with this command. # Tel e phone on-hook. #0 Link OFF. *0 Full duplex link ON, used if you have 2 repeaters tied together. A Key transmitter on for X time.
1.4.2 SETTING UP YOUR ID
You are now ready to change or setup the station identification, following will show how this ID is programmed into the controller. Once you have reviewed this procedure, you may want to review section 5.4 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 has a 3 digit command number. See the default CW data table in section 4.5.31 for a list of all CW commands. The data for all messages or CW commands are stored in the same memory area as the macros. When entering a new message or changing a message, care should be taken 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 = 023 697 Hz tone Character 3 = 042 CW Speed, 16 WPM Character 4 = 088 CW Space Character 5 = 069 CW “H” Character 6 = 066 CW “E” Character 7 = 073 CW “L” Character 8 = 073 CW “L” Character 9 = 076 CW “O” Character 10 = 002 End Of Message
ID message
. The factory default ID is “Hello”. The
Page 9
Review the following procedure to enter this “Hello” ID into the controller. Un-key your radio after each command, you should hear a CW “OK”. This will tell you that you did everything correctly. If you hear a CW “ERROR”, a mistake was made and the command was aborted.

14. 68 085 S-Command 68, Trigger a message or macro at start line 085. Use this to test your message.
15. 69 S-Command 69, Lock the controller, you are done.
Now you are ready to enter your ID m e ssage. Use the above examp le to organize your message. The re are bla nk t able for ms in the appendix that can be used to keep track of the data. It is important to know how the memory is organized so that you will know what the next available start line will be. The table below shows the default ID and how the above data was stored into memory.

1.4.3 SETUP CTCSS/DCS DECODE
The RI-200 controller is equipped with 6 independent tone panels for 6 different internal functions. These tone panels will be discussed in greater detail later in the manual. The CTCSS/DCS LED will show when the controller is decoding a repeater CTCSS tone, even though this current decode is not being used in the controller operation. The SYS, AUX, DTMF an d HOOK LED’s will flash at a rate of 4 times per second when these tone panel functions are also decoding tones. These 6 tone panels have the following functions;
Tone panel #1, Repeater audio. Tone panel #2, User commands. Tone panel #3, S-Commands (commands for programming). This tone panel will also allow access of user commands. Tone panel #4, Auxiliary input / output audio. Used when connecting two controllers together. Tone panel #5, Telephone audio. Used to access, dial and pass audio to the telephone interconnect. Tone panel #6, Dial Click. Used for dial click commands. See S-Command 49.
The controller comes programmed with 100 Hz CTCSS tone ready for use in all 6 tone panels. But before the controller will use this tone for operation, you must enable each of the functions associated with each tone panel. See S-Commands 01 for repeater, 14 for user and S-Commands, 34 for auxiliary, 49 for dial click and 72 for telephone access. You can enable or disable any combination of the CTCSS tones or DCS codes. See section 4.5.20 for more details. The following example assumes that you want to disable 100.0 Hz and enable 127.3 Hz for all tone panels. See the CTCSS tone table in section
4.5.20 for your specific tone number.
S-Command Description
1. 123456 Unlock the controller, you are in S-Command mode.
2. 20 0 013 0 S-Command 20, Disable the 100.0 Hz tone for all tone panels.
3. 20 0 002 1 S-Command 20, Enable the 127.3 Hz tone for all tone panels.

6. 72 1 S-Command 72, Enable telephone interconnect for CTCSS/DCS operation.
7. 69 S-Command 69, Lock the controller, you are done.
1.4.4 SET CTCSS/DCS ENCODE
The RI-200 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 turn off the encoder, or encode only one tone at all times, you will need to change this mode of S-Command 22. See section 4.5.22 for more details.
1.4.5 YOUR CONTROLLER SERIAL NUMBER
On the backside of the PC Board or 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 reset the program or S-Command 59 to re-initialize the memory.
Controller serial number _______________________

1.4.6 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 digits 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, 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 S-Command mode and accidentally send this password, you will turn off the system instead, oops!!
S-Command Description
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 ?????? S-Command 55 and your new 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 all the factory defaults to regain access to the S-Command mode again.
4. 69 S-Command 69, Lock the controller, you are done.
5. ?????? Check your new password, send “( You r password)”, you SHOULD hea r a fun ction complete “OK”.
6. 69 Re-lock the controller.
1.5 AUXILIARY INPUT/OUTPUT
The RI-200 has auxiliary input and output capability for connecting to another RI-200 repeater controller, or connecting to a sin g le contr ol receiver . By inter fa cing a s econd RI-200, two repeaters, two lin ks or one repeater and one link maybe interconnected. Audio paths and a digital serial data path provide all the communication that is required when connecting two controllers together. This allows the two repeaters or links to operate separately or cross-connected. The digital serial data link is selected by S-Command 37 1. For added protection, the serial data link protocol contains an error check routine and if a unit does not receive valid data for four seconds, that RI-200 will return to a normal operating mode. This is to prevent a transmitter from staying keyed-down because of a serial data failure.
1.6 PROGRAMMING SOFTWARE
An optional programming software and cable are available. This software is designed to run in Windows 95 or NT and will allow you to read, change and save all parameters within the RI-200. For software installation, follow the instructions included with the software disk. The supplied programming cable has a circuit board and connector at one end and a flat cable conn ector at the other end. Make sure that th e power is turned off on the repeater and controller before plugging the flat cable end into the RI-200 controller. The flat cable end plugs into the AUX connector on the controller. You will find a key on the flat cable connector. Align the key with the notch on the AUX connector of the RI-200 controller. At the other end of the cable is a ci rcuit board with a connector , p l u g t he connector di rectly into your computer COMM p or t . Now you can turn on the power to the repeater and controller. Make sure that you turn off the repeater / controller power before unplugging the programming cable.
DANGER!!!
Do not use this cable for connecting 2 controllers together, damage will occur to the controllers.

REPEATER INTERFACE
2.0 REPEATER INTERFACE
If you have installed the RI-210 into the Vertex repeater, all of the required interface has been implemented for you. You can skip down to section 2.8. If you are installing the RI-200, you should continue with this section.
This section will cover connecting your RI-200 to your repeater in detail. The RI-200 is ready to interface to your repeater. To ensure a successful installation, please follow these few simple steps. Review this section completely and plan you repeater interface before you start making connections. Enjoy setting audio remotely from your radio. See section 3.4 of this manual for more details on making level adjustments.
The diagram on the right is an end view of the radio interface connector on your RI-200. Use the supplied DB-15 male connector for making all connections to the controller.
RADIO INTERFACE CONNECTOR
2.1 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 have what is known as audio pre-emphasis. Pre­emphasis means that with increasing audio frequency the amount of the modulation will increase. The reverse is performed in all FM receivers a nd is called de-emphasis. The RI-200 was designed to operate with flat audio response from the repeater receiver and transmitter. This means that no de-emphasis and pre-emphasis of the audio is performed on the repeater or controller. This leaves all of the emphasis filtering in the user's radio. The RI-200 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 RI­200 and a FM modulator is when a varactor diode is directly driven. However the RI-200 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 char a cteri sti cs. Th e input connections to the RI-200 must be connected directly to the receiver’s discriminator for the squelch to work properly. On some receivers t his connection can be mad e to the squ elch circuit input.
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 t he controller, the receiver, or the transmitter. The RI-200 repeater controller has a built in audio level meter for setting the RX input level. See section 3.4 for more details on adjusting the audio levels in the controller. Consider and pr acti ce the above an d you will have repeater audio that you and your repeater users will be proud of.
2.2 POWER SUPPLY CONNECTIONS
The RI-200 operates on 12 volts DC nominal. The DC source voltage must be between 10 and 15 VDC. The controller typically draws 50 ma without the status LED’s 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 r epeater builder ma y 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

2.3 REPEATER RECEIVER AUDIO CONNECTION
Since the RI-200 controller has the squelch or COR/COS circuits incorporated on board, the audio input conn ected dir ectly to the receiver discriminator output. Connect the receiver discriminator audio to the RI-200 J1 pin 2 and the receiver g round or audio retur n to J1 pi n 10. Do repea ter r eceiver, get assista nce from som eone knowledg eable on the subject or contact our factor y 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 li ne 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 shielded cable. The controller’s audio path has a flat frequency 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 char a cteri stics.

2.4 REPEATER TRANSMITTER AUDIO CONNECTIONS
Whenever possible, use a direct FM type modulator. However the RI-200 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 microphone inputs have significant audio shaping, compensating for the microphone response and other characteristics. Always use 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 11. If a FM modulator without pre-emphasis is not available, the RI-200 can be jumped to drive a phase modulator or modulator with pre-emphasis. This is done by selecting the de-emphasis mode, S-Command 02 3 and changing the position of the on board jumper. The on board jumper should be set with the shunt on the side closest to U10. The side with the shunt closest to J3 is for driving a non de-emphasis modulator.
2.5 REPEATER TRANSMITTER PTT OR TRANSMIT KEYING CONNECTION
The RI-200 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 60 ma of current. Connect J1 pin 4 to the repeater transmitter PTT.
WARNING
- As with all repeater controllers, the
2.6 DIGITAL IN PUTS
The RI-200 has three 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 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 4.5.45 and 4.5.46 for additional information on programming these inputs. Th ese inputs are located on J1 pin s 6, 7 a nd 8. See the conn ector diagram on the previous page.
2.7 DIGITAL O U TPUT S
The RI-200 has three digital outputs 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 are CMOS gates with a voltage swing of 0 to 5, VDC TTL levels. Using S-Commands (or macros that are composed of S-Commands), each output may be turned on or off or pulsed with the desired S-Commands. See Sections 4.5.46 and 4.5.47 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.
Page 14
2.8 CONNECTING TWO RI-200 REPEATER CONTROLLERS TOGETHER
You can connect two RI-200 repeater controllers together using the auxiliary interface connector. Over this port, the two controllers will exchange audio, PTT and command information. The PTT and S-Command information is sent between the two controllers as serial data. A fixed data time­out 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. The two radios may be a repeater and a link, two links, two repeaters or a remote base.
When you h ave two contr ol lers connected tog ether, you can clone one controller to another. See S-Command 38 mode 2. Cloning is the process of copying the setting from one controller to another controller.
Connect the two controllers together with the optional IC-200 inter conn ect cable. If you prefer to make your own cable, the connectors at each end of the 16 conductor flat ribbon cable are “pin fl ipped ” with res pect t o each other.
Reference Macro Programming Section 5.0. Command information is sent from one controller to another by writing macros with data telling the controller to send S-Command information to another controller and not to process that S-Command within itself. To build a macro that will process S-Commands within th e local controller, follow all the normal procedures in this manual and in the programming macro’s section 5.0. When building a macro with S-Commands that needs to be processed by another RI-200 controller, you simply insert an “A1” before the S-Command and its data within the macro. All data from the “A1” through the “C” S-Command separator will be sent to the second controller. Each controller in the system will need to have 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.
AUXILIARY INTERFACE CONNECTOR
Note: The “controller unit address” is set with S-Command 38 and can be any address 1 through 9. The default address is
1, which can be used by both cont rollers, when only two contr ol lers are conn ected together.
To transfer serial data between controllers, S-Command 37 must be in the default state mode 1 (37 1) serial port data transfer mode.
The RI-200 also has a digit state data mode. S-Command 37 mode 0 used when connecting to someone else’s controller. In this mode the auxiliary interface TTL level input and output digital signals are LOW TRUE or LOW ACTIVE. The COS input is the same as the RXD input and the PTT output is the same as TXD output.

OPERATING AND ADJUSTING THE CONTROLLER
3.0 OPERATING
There are two types of control operations, user commands and system commands. The system commands or (S-Commands) are the principle means for the repeater owner to configure and control the RI-200's basic operations. These commands typically change the characteristics of the system or turn on/off functions of the system. The user commands are commands that the repeater owner builds to customize the repeater for the users.
3.1 SYSTEM STATUS INDICATORS
The system status LED indicators will display the current status of the controller. S-Command 09 is pr ovided to ena ble or d isabl e (turn on or off) all status LEDs. This will lower the current drain of the controller and may be important in a solar or portable repeater configuration. With the status LEDs turned off, the controller will draw less than 60 ma. During the controller power on self-test, the RI-200 will turn on all of the status LEDs for 1 second. The status display also doubles as a receive l evel audiometer. When you press the “INIT” button after the power is on, the display will show receive deviation. When the LEDs labeled :SYSTEM” through the “PTT” are on, the input deviation is 1.5 KHz. When all LED’s are on and the ring LED just came on, the input deviation is
2.5 KHz. The following is a list of status LEDs and their function.

TONE or DCS CODE. COS Car rier Operated Switch, indicates when a sig nal i s presen t at the receiver. CTCSS/DCS Continuous Tone Controlled Squelch System and Digital Coded Squelch, indicates when a sub-audio tone
or digital code that has been enabled in the repeater CTCSS /DCS is present at the receiver. AUX Shows when there is activity coming from the AUX link port. This LED will also flash at a rate of 4 times
a second when the controller is decoding an enabled Auxiliary CTCSS TONE or DCS CODE. 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). This LED
will also flash at a rate of 4 times a second when the controller is decoding an enabled User Command
CTCSS TONE or DCS CODE. HOOK Shows when the telephone is off-hook or a telephone call is in progress. This LED will also flash at a rate
of 4 times a second when the controller is decoding an enabled Telephone CTCSS TONE or DCS CODE. RING The controller has detected an incoming ring signal from the telephone line.
3.2 DTMF COMMAND INPUT
Dual Tone Multi Frequency or DTMF is typically used in telephone system for dialing. The RI-200 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 without delay, 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, so you can use the “C” digit to perform the same as the un-key action. 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.
Page 16
3.3 TELEMETRY M ES S AG ES
Telemetry or messages are sent from the controller to you in response to a repeater status or function. There are primarily three types of messages. 1) The station ID. 2) Courtesy messages, which occur after you un-key. 3) System functions (OK, ERROR and system status). Any of the messages may be modified with S-Command 31. The controller comes pre­programmed with default messages in response to any one of the following events:
EVENT DESCRIPTION
Clock Set Courtesy Courtesy message is sent after each user unkeys to let other users know when the time-out timer
has been reset and it is OK to continue talking. This message occurs when the time clock has been
set. Weak Si g nal Cou rtesy Replaces th e courtesy messag e when the received signa l is weak or noisy. Clock not Set Courtesy Replaces the courtesy message after power has been restored to the controller. This message is
used when the time clock has not been set. Un-lock Courtesy Replaces the courtesy message when the controller is unlocked or in S-Command mode. Post time-out Generated when the time-out offender releases his PTT to inform the user of this condition. Pre time-out Generated just before the controller chops off the transmission of the user that timed out. ID This is the system identification, usually in CW. The factory default is “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. Ring Generated in response to someone calling on the telephone. AP Answer Message sent to someone calling on the phone when the controller is waiting for a password. AP Function Complete Generated on the telephone in response to an S-Command the controller understood and executed. AP Error Generated on the telephone in response to an S-Command the controller did not understand. AP Ring Back Generated on the telephone to identify that ringing is in process on the repeater.
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.
3.4 SETTING AUDIO LEVELS
The RI-210 is shipped with audio levels already set for the Vertex repeater, h owever final adjustments may be requir ed. If you are installing a RI-200 or checking the RI-210 audio levels, use the following procedure.
Warning
settings are returned to their default settings. 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
2. The un-key of your radio when sending a command is a normal command termination. If you are experiencing a

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-200 design has a wide dynamic range for all of the decoders and should work in most conditions.
problem when getting started or the COS is always on, you can use the “C” DTMF character for the command termination. This should only be necessary until you get the receiver and squelch p roperl y set.
. During full
Page 17
3. If you experience some problems decoding DTMF, the likely problem is that the tone levels are out of range. The DTMF
decoder has 30+ dB dynamic range and decoding DTMF should not be a problem with a reasonable discriminator input level. The DTMF status LED lights when a tone is first decoded and remains lit until after either a function complete or a DTMF Inter-digit time-out. We have seen problems where one row or column did not decode properly. To test this, send one by one digit, all DTMF tone digits, letting the LED light drop off 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” t elemetry mess age, the controller may alrea dy be
unlocked. You can identify this condition because of the courtesy message will be different.
3.4.1 SETTING RECEIVER INPUT GAIN ( R 3)
For the squelch and internal decoders to work properly, you need to set u p the receiver in put aud io level. The receiver inp u t audio level setting is a manual adjustment. Use the follow the procedure;
1. Apply the 12 VDC power source. Confirm the green system LED is on.
2. If the system LED is not on, see the section on troubleshooting.
3. Transmit a carrier on the repeater’s input channel. Did the yellow COS light come on? Do not be surprised if the COS
LED did not come on or is already on, as we have two adjustments to make before the squelch circuit will work correctly.
4. Generate a 1000 Hz tone at 1.5 or 2.5 kHz deviation on the repeater input.
5. Adjust the receiver audio pot on the front panel for a level of 0.44 Vrms (1.5 kHzD) or 0.73 Vrms (2.5 kHzD) at U1 p in
8. You can also skip to step 7.
6. If a service monitor is not available, you can use the number “5” button on a DTMF equipped radio. Most radios should
be setup to deviate 1.5 kHz..
7. The RI-200 has a built in audio level meter. While you are sending your test tone, press the button on the circuit board
labeled “INIT” The system LED’s will operate as a level meter, the first red LED will indicate 1.5 kHz deviation and the last red LED will indicate 2.5 kHz deviation.
8. The receiver input level is adjusted by the m u lti turn pot R3 labeled “RCVR” located right of the radio interface
connector.
3.4.2 SETTING SQUELCH STAGE GAIN (S - CO M MAND 50)
The RI-200 uses digital pots for some of its level settings. The digital pots have electrical shaft positions called steps. Each pot has 64 steps, ranging from 0 to 63. There is an S-Command to set the pots to specific steps or allow up and down control of the pot. Each digital pot in the RI-200 has a default setting. See Section 4 for details on each default setting. If the squelch is open (COS LED on all the time), it will be necessary to use the “C” command terminator to get the controller to accept any command, including the password. The following procedure will outline how to set up the digital squelch pot.
1. Correctly enter the password.
2. Enter the squelch pot step value with the S-Command 50 [level], where the level is a pot step value between 00 and 63.
See Section 4.5.50 for the factory default level. If the COS LED is on all the time, you need to set the pot to a higher level. Try sending 50 45.
3. If your squelch is too tight, you can try sending a 50 20.
4. For be s t performance, set the squelch pot 2 or 3 steps above the open s quelch thres hold.
5. Lock the controller, you have now completed the squelch level pot setup.
3.4.3 ADJUSTING THE REPEATER TRANSMITTER (S-CO MMAND 12)
After hooking up the repeater transmitter audio and the repeater PTT keying circuit per Section 2, 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 ca n be easil y flip p ed back an d forth between the repeater inp u t and output channel whil e listening to the levels. Ideally you will have the same transmit deviation going out of the repeater transmitter as coming in the receiver. Tra nsmit 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 remotely adjusted with a digital pot in the same manner as the squelch, except with S-Command 12. When you have finished this adjustment, you have a working repeater with all audio levels correctly adjusted.
Page 18
3.5 SMARTSQUELCH AND NORMAL SQUELCH OPERATION
One of the most powerful features of the RI-200 controller is its built-in squelch circuit (COS). The RI-200 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 mode, the squelch will operate similarly to that of a standard radio. You can change the squelch level and the upper and lower squelch threshold. 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-200 detects that a user is not full quieting on th e repeater input, it will change the courtesy message to the “weak signal message”, in place of the normal courtesy message.
3.6 CTCSS DECODE AND ENCODE OPERATION
CTCSS (Continuous Tone Controlled Squelch System) decode and encode is provided as a standard feature on the RI-200 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 different group of tones for different functions. These tone panels have the following functions:
Tone panel #1, Repeater audio. Tone panel #2, User commands. Tone panel #3, S-Commands (commands for programming). This tone panel will also allow access of user commands. Tone panel #4, Auxiliary output audio. Used when connecting multiple controllers together. Tone panel #5, Telephone audio. Used to access, dial and pass audio to the telephone interconnect. Tone panel #6, Dial Click. Used for dial click commands, see S-Command 49.
The controller comes programmed with 100 Hz CTCSS tone ready for use in all 6 tone panels. But before the controller will use this tone for operation, you must enable each of the functions associated with each tone panel. See S-Commands 02 for repeater, 14 for macro and S-Commands, 34 for auxiliary, 49 for dial click and 72 for telephone. The decode tones for these tone panels are selected with S-Commands 20. The factory default tone for all tone panels is 100.0 Hz. The default tone may be changed or additional tones added. Once you have selected the tones that you want to decode, you will need to enable each of the tone panels.
Each of the tone panels will indicate when a valid tone is being decoded via the display. A valid repeater CTCSS tone or DCS code is shown by the CTCSS/DCS LED on continuously. A valid S-Command, User Command, AUX, and telephone CTCSS tones or DC S codes are shown by SYS, AUX, DTMF and Hook LED flashing at a rate of 4 times a second. During the LED flash, the LED will only be on for 10mS.
CTCSS encode tones may be any one 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 CTCSS tones may be passed to the repeater tran smitter, filtered (removed with a high pass filter with no tone going out the repeater transmitter), or the incoming tone may be filtered out and encoding of a CTCSS tone either on the same or a selected different frequency is possible. The CTCSS encode mode is set by S-Command 21 and allows you to run the tone at all times or only during decode of the incoming tone.
3.7 DCS DECODE AND ENCODE SETUP AND OPERATION
If you ordered your controller with the DCS (Digital Controlled Squelch) decode and encode option, 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 operation for DCS is the same as CTCSS.
Page 19
Depending on your repeater, you may have to change the polarity of the DCS TX/RX data. Once you have confirmed that 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 (S-Command 25).
CTCSS (Continuous Tone Coded Squelch System) uses contin uous tones below 300 Hz. A single tone is assigned for a group of users. When this tone is 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 wavefor m s 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 r esembles figure 2, your modulator or discriminator does not have enough low frequency response. Figure 2 was created 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
Figure 1
Figure 2
digital code word.
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 signal spectrum occupies considerable more bandwidth. A poor low frequency response in the transmitter or receiver may not ser iously distort a single fr eq uency tone si g nal but may seriously degrade a wide band s ignal containing multiple frequency components. The distortion risk is especially high if the frequency response delays the wide band frequency components.
The RI-200 does include data error correction. But if too many errors occur, you may experience some blocking out of the decoder. Errors can occur becaus e of unwant ed low frequency energy. The DCS decoder s can be effected 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-200 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 con fi rm that the rad ios used to operate the repeater, have some type of sub audio filtering.
You will find that it is extremely important for the receiver and trans mitter to be on frequency to achieve maximum performance of the DCS function. Errors in the transmitter and receiver frequen ci es s how up at t he 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.

3.8 INITIALIZATION PROCEDURE
There are two distinctive methods of re-initializing and returning to factory default data. Default data for each of the S-Commands are listed in section 4 and the System Command Table at the end of this manual. To initialize the RI-200 data, use the following p rocedure:
1. Turn power to the RI-200 off.
2. While depressing the initialization button, turn power back on.
3. Wait until all the status LED’s turn on and release the initialization button.
4. During this initialization procedure all default data except the audio level digital pot positions were loaded into the
repeater controller’s “EEPROM” non-volatile memory. During the writing process to the EEPROM, all status LED’s will remain on (approximately 3 to 5 seconds).
5. If you need to initialize the digital pot audio levels, during power on initialization continue holding 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.
Pressing the initialization button while power is applied after the fifteen seconds initialization time-out will not change any data or be detrimental. After the power has been on for fifteen seconds, the initialization button can be pressed to turn the LED di sp lay into a receiver audio level meter.
3.9 EVENT SCHEDULER
The RI-200 has an event 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 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 NO T SET” CO URTESY 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 standard courtesy message to the CW “RST” message, send “32 03 39” and
un-key, you will hear a function complete.
3. You are done, send “69” to lock the controller.
4. You will now notice a new courtesy message.
Once the system time clock has been set and the schedulers have been setup, command will automatically execute. Eight individual schedulers are available. To setup the scheduler, use S-Command 44. See the programming section for more details.

PROGRAMMING
4.0 PROGRAMMING
Customizing the RI-200 for your application is performed through programming. Programming is done with (System Commands) S-Commands and is performed over the air or over the telephone. Not only can you change any of the system perameters, but you can also change or create your own user commands.
The RI-200 contains powerful tools with 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 5 for additional information on this subject.
When controlling the RI-200, you are always in one of the two modes, never in both. To enter the programming mode the correct password (section 4.2) must be executed. To exit the programming mode and return back to the User Command mode the S-Command 69 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 :
Normal operating mode
1.
Programming mode
2.
At all times the controller is in one of two command modes:
where User Commands are functional.
where System Commands “S-Commands” are used to customize the repeater operation.
4.1 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 this section will detail its own syntax.
4.2 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-200 controller will return an acknowledgment message (default is CW “OK”). 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. If the controller did not understand the S-Command you will get a CW error message (default is CW “ERROR”).
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. Do not use a “C” in your password. 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.
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”.
4. 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.
5. You are done, send “69” to lock the controller.
6. Check your new password, send “(Your password)” and un-key, you will hear a function complete “OK”.
7. Re-lock the controller, send “69”
Page 22
Should you forget your password, you will have to turn off power to the RI-200 contr oller, then simultan eously 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. Space has been provided at the end of the manual for these notes.
Some controller owners have experienced the following problems:
When the receiver input l evel or squelch is not setup cor rectly an d the COS LED on the front p anel will not go out. You need to check the receiver in p ut level (Section 3.4.1) and/or adjust the squelch (Sect ion 3.4 .2). Until th e squelch is properly adjusted, you will have to terminate all commands with a “C”. This DTMF character performs the same function as Un-keying your radio.
The s econd problem is when you enter t he corr ect password a nd you receive a n “OK” mess age. A mom ent later you enter your password again. If this and following attempts, you receive an “ERROR” message. What happened? When the fi rst password was executed and you recei ved an “OK” message, you are in the S-Comman d or programming mode. In the S-Command mode and if your password does not look like an S-Command you will get an “ERROR” message because the controller thought that you entered an S-Command with bad data. If your password looks like a valid S-Command to the controller, you will have executed that S-Command instead of the password. For example, the default password is 123456. The first time you enter the password you get an “OK”. If you send a 123456 again th e 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 will respond with an “ERROR” message.
When you are finished programming, always re-lock your controller by sending the S-Command 69. Also, there is a time-out timer on the controller. When the controller is unlocked, the timer will re-lock the controller 5 minutes after the last valid S­Command. If you hear an “OK” and you did not expect it (as you did not enter an S-Command) then the controller has automatically executed the lock command.
4.2.1 AUXILIARY CONTROLLER PASSWORD ACCESS
When you have two RI-200’s connected together, you can unlock and control the auxiliary controller. Unlocking another controller is done by adding an A1 to the end of the local controller’s password. Once the auxiliary controller is unlocked you can send S-Commands to that controller as usual. Use the following example:
1. Assume the local controller password is 123456 an d t he auxiliary controller password is 987654.
2. Assume the l ocal a nd auxiliary controller’s unit address is 1.
3. From the local controller, send “123456A1” and un key. You should hear a function complete, CW “OK”.
4. The auxiliary controller is now un-locked and you can send S-Commands to that controller in the normal format.
5. When your are done, send S-Command 69 to lock the auxiliary controller.
4.3 VALID S-COMMAND and DATA
All DTMF digits are valid as data in an S-Command or as macro data. The DTMF character “C” is the only digit not valid as data, this character is used by the controller as a command terminator or instead of unkeying your radio. The RI-200 will validate all data with in an S-Command. If any of data fields are out of range, have an incorrect number of digits or missing digits, the RI-200 will not modify the S-Command data and will return with an error message.
Page 23
4.4 RULES FOR LEADING ZEROS IN S-COMM ANDS
Leading zeros means that if a command requires a 3 digit value, whether the value is 001 or 100, a total of 3 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 rule. 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. All commands requiring multiple parameters, require leading zeros for each parameter except for the last parameter. 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. If you are not sure, always use leading zeros especially when you are not yet familiar with the controller.
4.5 SYSTEM- COMMANDS (S-Commands)
The following sections will detail each of the S-Commands showing syntax, examples, and the default data values. To make S-Commands easier to locate, the last two digits of each sub-section numbers matches the S-Command number. To execute an S-Command you must first “unlock” the controller with the current password. When “unlocked” the user commands will not work. When you are done, “lock” the controller with S-Command 69. You are now in the user command mode.
When you are sending commands via DTMF, the controller is always in one of the 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. When the controller is in this mode, you will hear an ascending 4 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 descending 4 tone (weak signal). When you send the programming password, th e RI-200 unlocks and will switch to a programming or System Command (S-Command) mode. When the controller is in this mode you will hear 2 tone courtesy each time you unkey with a full quieting signal. Again in this mode, if your signal is not full quieting, the courtesy message will change to a descending 4 tone.
Each time you send commands to the RI-200, you will get one of 3 responses. First, if you send any valid command without errors, the RI-200 will respond with a CW acknowledgment message “OK”. This message is lower pitch and h as the rhythm of “dah dah dah dah dit dah”. Second, if you send an S-Command with an error or a user command that has an error in its programming, the RI-200 will respond with a CW error message “ERROR”. This message is high pitch and has the rhythm of “dit di dah dit di dah dit dah dah dah di dah dit”. Third, if you send invalid command, the RI-200 will not respond with any message.
When you are programming your RI-200 over the air, it is important to have a full quieting signal to the repeater. As 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:
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 looks like some other valid command. If you move in and out of a 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-200 is in the User Command mode while you are trying to send S-Commands and the other way around. Note
•
that if you are in the S-Command mode after 5 minutes have past without sending a command, the controller will lock itself. When this happens, you will hear a CW “OK” without sending a command.
4.5.00 NO OPERATION
This is a null command and does not perform an internal function. Primarily, a NOP is used to write over data in a macro that is no longer desired.

4.5.01 SYSTEM MODE
System mode determines what conditions are required to key the repeater and pass audio from the repeater receiver to the repeater transmitter. When the system is in mode 0 (Off), the repeater will appear dead to the users and all functions like telephone and auxiliary are disabled. User and S-Command are still available. When the system is off, the “SYSTEM” status LED will also be off. All other LED’s like COS and CTCSS will still show their associated status.
SYNTAX: 01 [Mode]
MINIMUM: 0
MAXIMUM: 6
UNITS: Mode 0 = System off.
Mode 1 = COS or car rier access only. Mode 2 = Repeater CT CSS/DCS access only.

4.5.05 FORCE PTT ON
Keys up or “locks on” the repeater transmitter for the selected number of seconds. This provides a constant repeater transmitter signal for runn in g test, measuring power output, or checking signal coverage as you drive around. Once the timer has expired, it will not reset itself. You can clear or reset this timer by entering a zero value for the time.
SYNTAX: 05 [Seconds]
MINIMUM: 0 (Reset timer)
MAXIMUM: 3600 Seconds (equals one hour m a x. )
UNITS: Seconds
DEFAULT: 0
EXAMPLE: 05 120 Lock on the repeater t ransmitter for 120 seconds (2 minutes).
05 300 Lock on the repeater tr an smitter for 300 seconds (5 minutes)
4.5.06 REPEATER TELEMETRY MODE
CW telemetry is divided into 3 groups (ID, function complete/error and everything else including courtesy tones). This command sets the CW telemetry responses to one of four modes. 1 - Everything Off, 2 - ID only, 3 - function complete & ID only and 4 - all on. This command can be used to turn off the function complete and error messages while keeping the ID on.
If you omit the mode data, the controller will temporarily suspend the function complete or error message. This suspended message is one time only, not effecting the previously selected mode. This feature can be used to keep a function complete message from occurring during a macro or user command. More commonly used during an automatic command or scheduled command.
SYNTAX: 06 [Mode]
MINIMUM: (No Data)
MAXIMUM: 3 (Al l On)
UNITS: Mode 0 = Everythin g off
Mode 1 = ID only Mode 2 = ID, function complete and function errors only. Mode 3 = All On No data = Temporarily suspend function complete or function error.
DEFAULT: Mode 3 = All On
EXAMPLE: 06 0 Turn off all telemetry responses
06 1 Turn on only the ID message.
4.5.07 ID INTERVAL TIMER
Select the time interval for the CW ID or station identification. The ID will try to be courteous in that it will wait for someone to un-key before the controller sends the ID. A cleanup ID will also occur after the repeater activity has stopped and the timer has elapsed.
SYNTAX: 07 [Time]
MINIMUM: 0 (Disable ID)
MAXIMUM: 255 (25.5 Minutes)
UNITS: Tenths of Minutes
DEFAULT: 100 (10.0 Minutes)
EXAMPLE: 07 55 5 .5 Minutes between IDs
Page 26
4.5.08 COURTESY MESSAGE TIMER
The courtesy message timer is the selected time from COS carrier dropping, to the start of a courtesy message. This applies to ALL types of courtesy messages. If the carrier is picked up prior to the courtesy timing out, the courtesy message will be skipped. When the courtesy message is started, the repeater time out timer is also reset.
SYNTAX: 08 [Time]
MINIMUM: 0 (Disable Courtesy)
MAXIMUM: 99 (9 .9 Seconds)
UNITS: Tenths of seconds (1/10 Seconds or 100 ms)
DEFAULT: 20 (2.0 Seconds)
EXAMPLE: 08 35 3 .5 Seconds
4.5.09 LED STATUS DISPLAY ON/OFF
The LED status display serves no purpose when someone is not present at the repeater. This command can be used to turn the LED status display on or off to reduce controller current drain. In low power or solar powered systems, this function can be useful to reduce the controller total power consumption.
SYNTAX: 09 [Mode]
MINIMUM: 0 (Off)
MAXIMUM: 1 (On)
UNITS: Mode 1 = On, Mode 0 = Off
DEFAULT: Mode 1, On
EXAMPLE: 09 0 Turns Status LED display off (reduce system current drain)
4.5.10 REPEATER TIM EO U T TIMER
The time-out timer sets the maximum length of a single transmission for a user. When the user’s transmission time has been exceeded, the rep eater t rans mitter 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. The timer can be reset by capturing the signal on the repeater input and by issuing the time­out reset S-Command. The reset command will need to be terminated with a “C” under the above con dition. This command could be sent over the Auxiliary Link or telephone if needed.
SYNTAX: 10 [Time]
MINIMUM: * (Manual reset), 0 (Disable time-out)
MAXIMUM: 255
UNITS: Tenths of minut es or 6 second increments.
“*” = Manual reset time out timer.

EXAMPLE: 14 0 1 Turn on both pan el s for u se
14 1 0 Turn off the user command tone panel
4.5.15 USER COMMAND DECODE ENAB LE
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 to place the command into. 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 on and off group 1. Now when the telephone is off-hook, you can disable all other commands. Also you could add a scheduled function to disable the user telephone commands during the night.
