Overview
Many different types of batteries may be used with Raveon’s M7 series of GPS transponders.  This Technical Brief describes how well some common battery types will work with the M7 radios. 
Actual battery life will vary based upon how often the M7 GPS transponder transmits, but the data in this Technical Brief may be used to [...]

The M7 transceiver has a 5-watt RF power output rating.  In a typical application the units is in Standby or Receive mode most of the time.  A small fraction of the time, it is transmitting.  But when it transmits, the M7 begins heating up, dissapating about 8 watts of heat.   This depends upon the RF [...]

Internal to Raveon’s M7 series of GPS transponders is a GPS receiver module made by Trimble.  It is their Copernicus II GPS receiver module.  Many of the M7’s performance specifications are driven by the use of this receiver module.  The Copernicus II is ideally suited for vehicle tracking systems, AVL, asset tracking, and personal location.   Details [...]

The M7’s I/O Connector
On the front of the M7 series of GPS transponders, is an Input / output (I/O) connector used to configure the unit.  This I/O connector supports RS232 serial data (422 optionally), as well as digital input and output.
The RS232 9-pin serial I/O connector is a female 9-pin D-subminiature connector having the [...]
