NOTE

Introduction

The TRL-35 is a transmit/receive/repeating Digital UHF modem. It is
a 35W high powered base radio that uses the same DSP technology as
is used in the GR-3 Digital UHF receiver.

The TRL-35 radio can be used to enhance the following survey­related systems:

• As a high power transmitter/receiver external UHF radio for any
base system

For example, with the GB or Legacy Series GPS Receiver.

• As a high power repeater (not in PDL protocol currently)

Obstructions such as buildings, terrain, trees, and so forth greatly
affect the usability and range of any radio system. However, the
TRL-35 as a high powered transmitter/repeater provides an increase
in the operational range and effectivity of the system in unfavorable
environments.

The TRL-35 extends the operational range of the
UHF system. It does not increase the range beyond
the rover’s OAF limitation.

The TRL-35 is compatible with:

• GR-3 Digital UHF Radio

• Existing Pacific Crest radios (currently only PDL radios using
GMSK modulation)

• Trimble radios using Trimtalk 450s (currently only Trimble
radios using GMSK modulation)

Simple features and configurations allow the TRL-35 to be adaptable
to most situations, and make it easy to use.

Introduction

TRL-35 LEDs

The four LEDs on the TRL-35 have the following indications for the
modem:

• Power LED
Solid green if power is connected to the modem.

• Sync LED
Solid red if a signal with a level exceeding the level required for

reception exists on the current radio channel frequency.

•Tx/Rx LED
Flashes green if the modem receives or transmits data over the

serial interface.

• Alarm LED
Solid red if an alarm is detected.

Standard Kit Cables and Accessories

The TRL-35 (P/N 30-070004-01) bill of materials includes power and
