The numbered steps cover the basics, through connecting your radios and adjusting the RLC-4. After that there is information concerning the other input and output features of the RLC-4: the serial interface, the logical output and input lines, and the analog input lines.
Page 20 3 volts to ground when a signal is present, the signal is active low. If the voltage goes from ground to a voltage above 3 volts the signal is active high. The RLC-4 accepts active low COR signals by default, but this can be changed for one or more of the radio ports with command 013.
Page 21 Step #5: Adjusting the RLC-4 Controller - Locate connector J1 on the RLC-4's main board. (It is the 10 pin female connector located near the tone level adjustments). This test bus will provide the signals that we need to adjust the audio inputs on the RLC-4.
Page 22 Follow the above adjustment steps for all other connected receivers Tone Generator Adjustment: - Generate a tone test sequence using RLC-4 using command 040 - Adjust "TN" pot on the RLC-4 to the desired deviation - 1.5Khz deviation is typical RLC-4 V1.79...
Page 23: Serial Port Interfacing
Serial Port Interfacing The RLC-4 has a full duplex serial port for interfacing to a computer or serial terminal; it is the DB-9 connector closest to the DB-25 I/O connector and power plug. This connection can be made with just a cable, a telephone modem, a packet TNC, or any other method that will send the serial characters back and forth (some have even used Telnet over the Internet).
Page 24 6, 8 and 20 together should fool the flow control into working. RS-232 Signals and Interfacing The RLC-4's input and output is the RS-232 standard, ±12V. The pinout is standard for a 9-pin serial connector. To connect to a terminal or computer's 9-pin serial connector, use a straight- through cable (not a null modem) with at least pins 2, 3, and 5 connected.
Page 25 Stop bits You can change the baud rate the RLC-4 uses with command 024. If you are using a modem, you may be able to set the baud rate that the modem uses to communicate with the controller to be different than the speed at which it connects to the other modem.

Page 31: How To Configure A Port As A Repeater
1-13 How to Configure a Port as a Repeater The RLC-4 controller supports a repeater on every port. This allows for multiple stand alone repeaters operating at the same time, on the same controller. We will describe how to configure and set up port one as a repeater.
Page 32: Example 1-1: Configuring A Port As A Repeater Or Link
To monitor a port from another port the following command is used 001 X Y Where X is the port doing the monitoring of port Y, Y is the port being monitored RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 33: Example 1-2: Configuring A Port's Cor/Pl Polarity
CTCSS inputs of all ports. If your receivers are already 'Low' you do not need to change the configuration. If your polarity is active 'High', you need to use command 013 to tell the controller your correct polarity. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 34: How To Program Your Beeps And Messages
The RLC-4 has separate CW generators for each port. All features including speed, frequency and message types can be set independently for each port. This allows the RLC-4 to be ID'ing more than one repeater at the same time, with different ID messages, frequencies and speeds.
Page 35: System Timers
1-17 System Timers The RLC-4 supports total user programming of all the system timers. This allows the user to define exactly how the RLC-4 works. The system timers are programmed using Command 020 and recalled with Command 021. Refer to Command 020 for more information.

Page 49: 013: Set Cor And Pl Active Levels
You could solve this problem by temporarily disconnecting the COR line from the receiver and manually attaching it to ground. This will cause the RLC-4 to think that the receiver is active (COR line is active low by default). You will have to disconnect that line from ground or press the 'D' key to simulate unkeying after entering each command.

Page 69: Chapter 5: Command Names
How Command Names and Command Numbers are Used: The RLC-4 controller has 250 commands. The first 150 are commands that do a specific task and are described in this manual. The rest of the commands are macros that automatically execute a sequence of other commands.
Page 70 If you know that entering a command name of "ABC123" causes a command to execute but you don't know what command number it is executing, you can use command 012 to find out by entering "012 ABC123" and unkeying or pressing enter. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 71 "Link up" instead. You could make a macro named "00012" or "00021" that would connect the two ports and send that message. Then entering "00012" or "00021" would cause your custom message to be sent, while "00013" or any other command RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 72 When all of the commands have their original names, there is no confusion because every command has its own unique three digit name, the command number. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 73: 010: Re-Program Command Names

Page 83: 031: Send A Dtmf Sequence Out Port 4
031: Send a DTMF Sequence Out Port 4 This command allows you to send DTMF tones out port 4. The RLC-4 is not capable of generating DTMF digits out other transmitters. See Command 044 to set up the length of the tones and pauses between tones.
Page 84: 040: Send A Tone
The pause length is limited to 60 seconds (6000). - FFFF is the frequency of the tone in Hertz (cycles per second). All four digits must be entered. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 85: Note About Courtesy Beeps
Note about Courtesy Beeps The RLC-4 courtesy beeps are not simply a programmable beep. When it is time to send a courtesy beep, the RLC-4 decides which ports should receive the courtesy beep, sets the audio routing variable to those ports (see Appendix A), and calls that port's courtesy beep macro (see Chapter 8).
Page 86 0660 is the frequency of one tone in hertz 6) Now when port 1's courtesy beep needs to be sent, the courtesy beep macro will call Command 040 three times to generate the three beeps. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...

Page 90: 044: Set Up Dtmf Regenerate Parameters
This command allows you to set up the DTMF regenerate parameters for port 4 (the only port that can generate DTMF). You may need to use this command to slow your DTMF tones down if a scanning DTMF decoder is on any of the attached systems that you want the RLC-4 to control. <044> aaaa bbbb Parameters: - 044 is the default command name.
Page 91: 051: Start Preaccess Tone
How to cancel the dial tone once it is running: 1) You can cancel the dial tone with a DTMF digit on the port dial tone is present. 2) When the dial tone timer expires (See Command 020) RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 92: The Digital Voice Recorder
It can be used to personalize your controller by recording any message or sounds that you want and playing them back for IDs or other messages. Interfacing: The DVR plugs into the “options” connector on the RLC-4. It will fit inside the optional rack mount cabinet. Recording Time: The voice storage chip on the DVR is capable of storing 75 seconds of audio.
Page 93: Erasing Tracks
You may never need to erase a DVR track, because you can record over them without erasing them first (just like with a tape recorder). If you do erase a track, and then try to play it, it should just play a short pause. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...

DTMF burst so that your message sounds clean. When it stops recording because it reaches the end of a slot, it does not back up to avoid wasting record time. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 95: 026: Playback Small Dvr Message(S)
- SS is the DVR slot number, two digits per slot Notes: DVR messages can be intermixed withCW messages and the RLC-4 will make sure that they are sent in the right order. For example, you could write a macro that would send your call sign using CW, then use the DVR to speak "Link Up".
Page 97: Chapter 7: Serial Port Commands
Chapter 7: Serial Port Commands The RLC-4's serial port is the closest DB-9 connector to the power jack. It is next to the radio port 4 connector. This chapter deals with the following topics: Information about serial transfers RS-232 baud rates...
Page 98: 024: Set Up Rs-232 Serial Baud Rate
024: Set Up RS-232 Serial Baud Rate This command allows you to set up the baud rate for the RLC-4's serial port. The baud rate should be set to match the computer, serial terminal, or modem that you have connected to it to program the controller with.
Page 99: 060: Set Up Serial Port Options
- Z (optional) is 1 to suppress serial (the default) or 0 to send serial caused by commands entered from DTMF - Q (optional) is 1 for queued serial (the default) or 0 to send it before continuing RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...

This allows upload files to contain spaces without affecting the format of the input data. If a user wishes to have a 'space like character' sent, the '_' (underscore) data can be used. RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 101: Chapter 8: Macros
There are at least two common understandings of what a macro is. The RLC-4 currently supports the more flexible of the two types; eventually it may support both. The kind the RLC-4 supports could be called a "multiple command macro" because it provides a way to execute a sequence of internal commands in response to one command from the user.
Page 102: Limits On Macros
Macro 174 could call macros 175, 176 and 177. Macro 174 is nested one level deeper than 173, so it is at level 3. Call Command 038 Call macro 173 Call Command 007 Call macro 174 Call macro 175 RLC-4 V1.79 Copyright © 1998 Link Communications Inc. 9/18/98...
Page 103 Macros 175, 176 and 177 are at level 4. Note that they are all at the same level. Any commands that are called from these macros will be at level 5. This is about as deep as the RLC-4 will let you nest macros, 5 or 6 levels.

Page 124 The point of this discussion is to make it clear that the controller does not care what the real-world quantity is, it just needs a variable voltage and the proper conversion ratio, and it can handle it. You tell the RLC-4 what the conversion ratio is by specifying two points: The first is what real world quantity would cause the sensor to output 0 volts.

Configuring the Autopatch: The RLC-4 can support four radios if the autopatch is not used. If the autopatch is used, port 4 can not be used for anything else. Command 110 allows you to tell the controller whether you want to use port 4 for a radio or whether you want to enable the autopatch.
Page 144: Hanging Up
Autopatches that are on a PBX often have to dial a '9' or some other combination of digits to reach the outside world. The RLC-4 has the ability to dial these digits for you. You can tell it what digits to dial and how long to delay before and after these "predial digits"...

Page 207: Appendix E: Controlling A Rotor
Appendix E: Controlling a Rotor The RLC-4 may eventually have specialized commands for controlling a rotor using the I/O lines on the I/O board, but you can do it now with a little work. • Connect the rotor controls to two of the output lines. We will assume that you have one output for on/off and another to select the direction.
Page 208 You can test the alarm we set in the above step by executing the motor CCW macro we made and making sure that it turns itself off when it gets to the CCW limit. The RLC-4 checks the alarm every second by default, but you can speed it up if you want to. Simply change the "I/O Polling Timer"...
Page 209 The high alarm should stop it when it gets to the proper position. • Reset the rotor and try the preset again.

This is caused by the RLC-4 trying to send back all of the descriptive responses to the commands and not being able to send the responses as fast as it gets new commands. Slowing the baud rate down will not help significantly, as that will slow down the responses just as much as the commands you are sending.

(longer for slow baud rates, shorter for fast baud rates). This will give the RLC-4 time to send the responses back without overflowing the queue. You may have to experiment to get enough delay to avoid overflowing without having to wait all day for the upload to finish.
Page 217: Appendix H: Using The Lm335 Temperature Sensor
Appendix H: Using the LM335 Temperature Sensor The RLC-4 supports the National Semiconductor LM335Z temperature sensor. The sensor converts temperature into voltage. This voltage is read by the controllers ADC (Analog-Digital Convertor) which allows the controller to read a voltage. When using the LM335Z sensor, the sensor needs to be powered in order for the temperature to be read.
