Introduction:
Congratulations, you have purchased a very powerful tool for your group's repeater. The RLC-3
may seem complicated and intimidating at first, but don't worry. Setting it up and programming it
are easy and straightforward, once you have read the manual. Please take the time to read it before
you try to start programming. This will save you a lot of confusion and frustration, as it should
answer most of your questions.
The RLC-3 communications controller supports up to 8 radio ports and two I/O boards (8 analog
voltage inputs, 8 logical (dry contact) inputs, and eight MOSFET output drivers each). The radio
ports can be configured to require one of several combinations of COR and PL inputs for access.
The RLC-3 has a DTMF decoder per radio port card, thereby supporting DTMF control from all
radio ports of the controller. Synthesized voice prompts the users in the programming of the
controller's variables, provides voice ID's and alarms based on the inputs, etc. The autopatch
includes 1000 programmable autodial numbers, cover tone, directed reverse patch and telephone
control. DVR, HF and VHF/UHF remote base support. All command codes, timer values, and
messages are programmable by owner. Each message can contain combinations of Morse code
characters, synthesized speech words, sound effects, DVR tracts, etc. The controller can be
programmed using DTMF from any of the radio ports, using DTMF from a telephone (using the
reverse autopatch), or from a computer using a serial cable or modem. The controller contains
several hundred command macros.. There is a clock/calender time chip with internal battery
backup for years of non-interrupted time piece operation. The timed event scheduler can be used
to automatically load configurations based on time of day and day of week settings. All input,
output, analog and radio interfacing signals can be assigned automatic event calls to allow
unattended functional operations.
This manual consists of three main sections: setup and interfacing, programming and commands,
and the appendices with commonly referenced tables and charts. A glossary has also been included
at the end to explain some of the terms and abbreviations that are used throughout the manual.
We have attempted to explain everything in a way that is easy to understand, but some questions
are inevitable. If you have carefully read the manual and still have questions, call us at (406)
