Safety

Exposure to RF energy is an important safety consideration. The Institute of Electrical and
Electronic Engineers (IEEE), the U.S. Department of the Navy, and the American National
Standards Institute (ANSI) created a standard set of guidelines titled

to Human Exposure to Radio Frequency Electromagnetic Fields, 300 kHz to 100 GHz

Safety Levels with Respect

. Based
on a wide variety of tests, the standard excludes from concern, devices that emit less than 7
watts at frequencies between 300 kHz and 1 GHz. The TRIMTALK 450S antenna emits less
than 0.5 watts on average at 430 to 470 MHz and is considered extremely safe. However, due
to the extreme sensitivity of human tissue to heating effects, Trimble recommends maintaining
a distance of at least 0.3 meter (one foot) from a TRIMTALK 450S base or repeater antenna.
The Trimble rover antenna is receive only and is safe at all distances.

Preface

xx TRIMTALK 450S Operation Manual

1 Overview

A set of TRIMTALK 450S radio modems form a wireless data
network. The unit is designed primarily for broadcasting low-latency
differential GP S (DGPS) corrections or raw GPS data from a survey
base receiver to one or more roving receivers for real-time differential
or real-time kinematic (RTK) GPS surveying.

1.1 TRIMTALK 450S Network

The base, rove rs, and repea ters in a TRIMTALK 450S netwo rk are all
identical units. The function of a particular unit (base, rover, or
repeater) is determined by its configuration. Units used as a base or
rover can be connected to most Trimble su rvey-grade GPS receivers
through a single cable for both power and serial I/O.

To achieve l ine-o f-sig ht (LOS) co v era ge t o all point s in a s urv e y a rea,
a TRIMTALK 450S network can include up to two repeaters. The
repeaters retransmit data packets according to a simple time-sharing
scheme to avoid mutual interference. The operation of the repeaters is
transparent to the rovers. A rover can move around and pick up data
packets from the base or repeaters, whichever the rover hears first.

Repeaters operate autonomously, they do not require anything
connected to their serial ports. TRIMTALK 450S radio modems also
have an auxiliary I/O connector that can configure the radio.

Whether one or two repeaters can be used in your TRIMTALK 450S
network is determined by the wireless data rate and information
content. To use two repeat ers, the wir eless data ra te mu st be 9600 bps
and the information cont ent must be T rimble CMR2 RTK packets at a
1 Hz rate.
