Introduction:

Congratulations, you have purchased a very powerful tool for your group's repeater. The RLC-1

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-1 repeater controller consists of one repeater port, one linking port, four analog voltage

inputs, four logical (dry contact) inputs, and five MOSFET output drivers. The repeater and

linking ports can be configured to require combinations of COR and PL inputs for access. The

RLC-1 has a single DTMF decoder that scans between the two receiver ports, thereby supporting

DTMF control from all ports of the controller. Speed selectable Morse Code prompts the users in

the programming of the controller's variables.

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 or fax us at

(406) 482-7515 or write to us at

than manufacturing defects, Link Communications will repair the product and bill the customer

for parts and labor. Contact Link Communications for more information.

What Link Communications will not cover:

1. Too much voltage to the controller. The RLC-1 operates at +11V to +15V, negative ground.

2. Damage to the controller by lightning, accident, or incorrect power hook-up.

3. Incorrect unit installation.

4. Damage caused by shipment (damage claims are handled by the carrier).

6. Repairs by other than Link Communications.

THIS WARRANTY HOLDS ONLY TO THE ORIGINAL PURCHASER

HOW TO GET SERVICE

Please contact Link Communications for servicing information and authorization.

Comments:

Setup and Interfacing

This section of the manual contains everything you should need to know to get your repeater

controller up and running. The numbered steps cover the basics, through connecting your radios

and adjusting the RLC-1. After that there is information concerning the other input and output

features of the RLC-1: the serial interface, the logical output and input lines, and the analog input

lines.

Step #1: Check the Packing List

Your package should contain the following items:

(1) RLC-1 Repeater Controller

(1) 2.50mm Power Connector

(3) DB-9 Male Solder Connectors

(1) DB-25 Male Solder Connector

(1) RLC-1 Manual

If any of these parts are missing, contact Link Communications.

Step #2: Connect Power

- The RLC-1 was designed to run off of 12V DC. 11V to 14V should work fine.

- Locate the 2.50mm power connector included in your parts bag.

- Unscrew the plastic outer shield and thread your power and ground wires through it (20 gauge

suggested).

- Solder the +12V wire to the center pin of the 2.50mm connector.

- Solder the ground wire to the shield of the 2.50mm power connector.

- Screw on the plastic outer shield.

- When power is applied to the RLC-1 controller, the DTMF Valid LED will flicker, and the

Repeater port transmitter will send out a CW message 'RESET ?'

Step #4: Connecting Your Receivers to the RLC-1

The main repeater and the link port connect to the RLC-1 using male DB-9 connectors

(included).

Main Port and Link Port

1 - Ground Reference

2 - PL Input (Active Low)

3 - PTT Out (Active Low)

4 - Audio Out (10K OHM)

5 - Audio In (10K OHM)

6 - Ground Reference

7 - COR Input (Selectable Polarity)

8 - Ground Reference

9 - Ground Reference

Connecting the Receiver COR:

- The first step in connecting your receiver is to locate a COR signal. This signal indicates if the

receiver is active or inactive. The RLC-1 will accept either an Active high COR (Goes from

ground to above 4 volts, or open), or an Active low COR (Goes from a voltage greater than 4

volts, to a ground, or goes from an open to a ground). The input impedance of the RLC-1 COR

input is 10KSand it is diode clamped with internal pull-up resistors. This allows it to handle

input voltages of up to 40 volts without damage to the controller. The COR input must not go

below 0V (ground); this would damage the Micro-Processor.

Selecting COR Polarity Jumpers:

Once you have determined the polarity of your COR signal, you need to tell the RLC-1 what the

polarity is. This is accomplished using jumpers J4 for the Main Receiver COR, and J5 for the

Link Receiver COR. When the jumper is connected across the 2 pins, the COR is expected to be

Active Low. When the jumper is not connected across the 2 pins, the COR is expected to be

Active High. The RLC-1 comes shipped with the COR's selected to be Active Low (Jumper

Connected)

Using one of the supplied DB-9 Male connectors, connect your COR signal to pin #7

Connecting a PL Input (optional):

- If you wish to use a PL (CTCSS) decoder on any of the receivers, it can be connected to pin #2

of the appropriate connector in the same fashion as the COR input. See Commands C005..C006

for information on using the PL input.

Connecting the Receiver Audio:

- 2 types of audio can be used on the RLC-1 controller:

Type 1: Deemphasized audio (Speaker Audio)

Type 2: Discriminator audio (Raw Unsquelched Audio)

- If type 1 audio is used, remove the appropriate jumper on the controller. This removes the

deemphasis filter from the circuit. As the controller comes shipped, all ports are set up for type 1

audio.

J1 - Main Receiver Deemphasis Jumper

J2 - Link 1 Receiver Deemphasis Jumper

- If type 2 audio is used, place the appropriate jumper in circuit (over both pins). This will place a

- 6dB/octave deemphasis filter into the circuit. Some discriminators can not directly drive the

10KSinput impedance. If this is the case, a pre-driver or different audio access point will be

required.

- The audio input is connected to pin #5 of the male DB-9 connector

- The audio adjustments will be described in Step #5.

How the DTMF Decoder Works:

The RLC-1's DTMF decoding circuit uses a scanner that enables the controller to receive tones

from all the ports, without mixing the two receiver's audio together. This allows the receivers to

have total control of the DTMF decoder when its Receiver is active. Once the decoder has

detected a tone on one of the ports, it stops scanning and waits up to four seconds for the next

digit. It is reset at the beginning of each DTMF digit. If any of the DTMF digits are held for

longer than 4 seconds or there is a pause of 4 seconds between digits, the DTMF scanner will

resume scanning and all digits entered up to that point will be lost.

Step #5: Connecting Your Transmitters to the RLC-1

Transmitter PTT:

- The RLC-1 produces an active low PTT signal (ground when PTT is active). This output is

buffered with an open drain type driver capable of sinking 150mA. There is a built in 30V zener

clamping diode to protect the PTT MOSFET from the high voltage spikes that can be caused by

interfacing to a PTT relay coil. Your transmitter PTT input should be connected to pin #3 of the

DB-9 connector.
