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. TX Timeout – Duration the controller will transmit continuously before keying
down.
4. TX Lead In – How long the controller waits after engaging the repeater PTT
before sending LTR telegrams. Provides a wait time to ensure repeater is on
frequency and can send full LTR telegrams without missing preamble of the
LTR telegram. Check your repeaters requirements.
10. Conventional CSQ/CTCSS – Select the RX and TX tone and Ident Mask Number.
11. Valid Repeater Array: This check box array tells this controller what other
controllers in the system it has permission to trunk calls to. It might be that
even though another controller is in the system, you may not want this particular
controller to trunk calls to it. This feature is good for mixing networked and non-
networked repeaters. You may not want a networked repeater trunking calls off
to non-networked channels. Also, this feature is nice when you are adding
repeater controllers to the site and have yet to upgrade the mobiles in the field.
12. Network Options:
1. Network Master – Select this checkbox if this controller is to function as the
network master. The network master will be the controller connected to the
TL-NET Gateway’s serial port. Check the only the one controller connected to
the TL-NET Gateway.
2. Network Array – This is a network master feature only. Check each box of all
the TL-NET controllers connected to the TL-NET Gateway’s audio ports. These
will be your network repeaters/controllers.
13. TX Audio Settings: Press the UPDATE CONTROLLER after adjustment is made.
1. Course – adjusts the TX Audio in 2.5 dB step increments.
2. Fine – adjust the TX Audio in 0.5 dB step increments.
3. CW ID – adjust the broadcast ID tone deviation.
4. TX Data – adjusts the TX LTR Data in 0.5 dB step increments.
14. Operating Mode – Sets mode of operation as either Repeater or Base
15. COS (Carrier Operated Switch) Polarity Output – Active Hi or Active LO
16. UPDATE CONTROLLER – Once changes are made, press this button to update the
controllers.
STEP 3: ALIGN THE CONTROLLER
For the next steps, reference the PCB layout Figure (see Figure on next page). You will
need to remove the unit’s cover to access the PCB.
There can be two different sources for the receive audio. One is the local audio coming
from the repeater’s receiver and the other is the Gateway connecting the audio from the
other sites. The local audio from the repeater’s receiver must be tuned first.
Adjust local receive audio first:
1. Program the service monitor for the repeater RX frequency. Inject a full-quieting 1kHz
tone deviating at 3.0 kHz (wide – 25kHz) 2.0 kHz (narrow – 12.5 kHz). Place
voltmeter on DC and put voltmeter probe on TP1. Adjust P1 until TP1 reads 2.5 Volts.
