4.8.2 Set up the Mobile System
1.
Set up the Mobile Radio as above, such that it obtains its system timing "OTA" or over the
air using beacons from the Base Radio.
2.
Obtain a GPS receiver that can output NMEA serial messages to a portable PC for logging
purposes.
3.
Configure the GPS receiver to output only $GPRMC sentences.
4.
Run the Poller application on a portable PC or laptop to travel with the mobile radio.
5.
Set up the mobile Poller application as shown in the following screen shots.
6.
When you start the test from the Mobile Poller application, use the "Start Receiving" button
instead of the "Start Polling" button. This puts the utility into receive-only mode.
Notes: You should set the mobile Poller to send to the portable PC's IP address (or 127.0.0.1) and
an unused port like 55555 because the mobile radio is not intended to transmit for this test. Set
the mobile Poller to log to the desired file. This file will contain your survey data including date,
time, GPS location and received signal strength. Set the Poller application to accept GPS NMEA
data from a GPS receiver via the appropriate serial port and mode.
