CHAPTER 1: INTRODUCTION Welcome Thank you for purchasing the ComLink TL/TL-NET local and wide-area LTR repeater controller. This Owner’s Manual will acquaint you with the features and show you how to program and interface the TL-NET LTR controller to your repeater system. Every effort has been made in the preparation of this manual to ensure the accuracy of its contents.
CHAPTER 2: INSTALLATION Step 1: Repeater Connection Build a cable to connect the controller to your repeater. The following table indicates the pins for repeater connecter J32. J32 – DSUB9 MALE - Repeater Connector Pin-out Pin 1- GND Pin 2- COR/COS Input (Active Low) +5V Pull-up Pin 3- RX Discriminator In –...

6. Select the Repeater Number and SYNC status. The Controller must be programmed to be either MASTER or SLAVE. NOTE: For proper stable communications between controllers and the PC, the terminating jumpers (J15-J20) must be installed on at least one controller attached to the repeater bus. It is also necessary that at least one controller be assigned the SYNC Master.

1. Idle Update interval – Duration the controller sends a free repeater telegrams when the controller is not busy. 2. Fade Timer – Duration the controller will continue to send LTR telegrams after it fails to decode valid LTR telegrams from the active mobile. 3.

ADJUST RX AUDIO GAIN: P4 adjust the RX Audio Gain from 0 to 1. The purpose of this adjustment is to reduce the gain in the event the receiver supplies too much signal for the controller. In most cases, this POT should be set full CW for unity gain (1). If more gain is needed, the internal audio signal processor will allow for increasing the signal.

PCB Layout Gateway audio – Each gateway supports adjustment of the audio volume to/from other sites. To adjust the audio for a specific channel, you will need to log on to the gateway’s web site and adjust the RECORD volume. Adjust Local TX audio: AC or DC coupling to repeater: J1 and J2 are three terminal jumpers that control the signal coupling to the transmitter.

TL CONTROLLER SETUP FORM 2. TX DATA ADJUST - With the transmitter connected to the service monitor and on the proper TX frequency, press the START button under TX Data Adjust. Increase or decrease the TX Data level until 1 kHz (wide) or 800Hz (Narrow) is achieved. Press STOP.

Radios won’t complete handshake: • Make sure TX Data polarity is correct for radios in the system. • Make sure TX Data levels are adequate for the respective channel spacing. Once a successful handshake is complete, check to confirm the Local and Network audio levels are all correct to your liking.
Chapter 3: Controller and System Connectivity In a trunking system the TL controllers communicate to each other through the repeater bus. The repeater bus uses the RS-485 standard to communicate. RS-485 requires terminating resistors. Terminating resistors reduce the transmission line effects caused by the signals propagating over long distances. To enable the terminating resistors, place shorting blocks across Jumpers J15-J20 on at least one controller in the system.
Chapter 4: Validation and Air-Time Each controller’s group idents can be validated/invalidated from three different sources: The TL Control Manager software, remotely through DTMF key sequences, and through the TL-NET Gateway from the TL-NET Gateway’s web server. This section deals with managing group idents from the TL Control Manager software.
CHAPTER 5: REMOTE MANAGEMENT Overview The TL-NET LTR controller supports the remote management of IDENTS and repeater controllers. IDENTS can be validated and invalidated over the air. Repeater Controllers can be validated/invalidated over the air. You can also reset a particular controller over the air. You must set up a specific HOME-ID combination for system operator usage in the TL Control Manager Software.
Appendix A: Trunking Controller Troubleshooting 1. Repeater fails to respond to handshake attempts: • Make sure you have the selected channel programmed for COS output enabled active low. • Make sure controller and radio’s Repeater Number and Area Bit are the same. •...
Equipment returned for repair must have a return merchandise authorization (RMA) number. To obtain an RMA contact our Technical Support Department at (816)-532-8451 or email techsupport@BridgeComSystems.com. All returned equipment must have the RMA number listed on the outside of the shipping container.
FCC Statements This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
