SignalTrack User's Guide

USING A CELLULAR MODEM

To use a cellular modem simply set up the Remote monitoring in the same fashion as you would to

monitor a site using the Ethernet.

CALIBRATING THE COMPASS

Prior to using SignalTrack in a mobile site it is recommended that you calibrate the compass. After

you mount the roof pod to your vehicle it is important to calibrate the compass to the magnetic

environment of your vehicle. Prior to calibrating the compass make sure you are in a clear area away

from any magnetic materials and that you can drive your car in a circle. With the program in the off

mode, select Calibrate Compass from the Setup menu. The program will instruct you on the

required maneuvers and data entry required to complete the calibration.

Note: A compass is not required to use SignalTrack; however, if a compass is not used the vehicle must be

moved after SignalTrack is put in the run mode so that the GPS receiver can calculate a heading.

SETTING UP THE GPS

A GPS receiver is used in the mobile configuration to provide the location of the mobile site.

A GPS receiver can also be used to synchronize the time base within SignalTrack to the GPS

messages. This is particularly useful if you have multiple sites running SignalTrack and you want the

logged data to agree at all the sites in the network. This feature can be used in either a fixed or

mobile configuration. See Timing Options (on page 67) to learn how to enable this feature.

The GPS receiver used must provide ONLY the standard GGA and VTG messages at a rate of once

per second. The DDF6074 is factory programmed to provide these messages. If you use a different

GPS receiver you must program it to provide these messages.

ACCEPTING DATA FROM ANOTHER SITE RUNNING SIGNALTRACK

SignalTrack can accept data from another site running the SignalTrack application. The site can be

linked into SignalTrack via radio modem, telephone modem, or via an Internet or intranet TCP/IP

connection.

RADIO MODEM

Follow the same instructions as was given for setting up Mobile Networking (see "Networking

Mobiles" on page 56) to link another fixed site into SignalTrack using a radio modem.
