4: Configuring the MP Modem to
Report GPS and I/O Data

• GPS configuration and
reporting
• I/O device installation
and configuration
The MP modem is capable of reporting position and heading
information using the embedded GPS module, as well as the
status of sensors, gauges, and alarms connected to the I/O
(Input/Output) port. The MP modem is typically installed in a
fleet of vehicles with the GPS and/or I/O data being sent to a
central office or dispatch for processing.
This chapter describes how to implement local reporting of
GPS and I/O data.
Chapter 5 describes how to configure your
MP modem to exchange data with your private network.
GPS configuration and
reporting
GPS receivers use an array of orbiting satellites operated by the
United States Department of Defense to triangulate their
coordinates on the earth’s surface. In order to use the GPS
module in the MP modem, a GPS antenna must be connected
to the MP modem. (The installation requires either two
antennas—one RF and one GPS—or a single combination RF/
GPS antenna.)

tions (document #2130313) on the Sierra Wireless web site,
