The Other Devices tab can be used to configure a GPS unit to send position coordinates to be written to the M5 file whenever a tag is detected and on the specified Reporting Interval, which defaults to every 15 minutes. GPS data is expected to be in NMEA sentence format and positions from GGA sentences will be parsed.

 

To configure a GPS unit both the M5 Control Panel and the M5 Monitor Service to which it is connected must be on version 2.1.3 or above.

 

 

 

The GPS coordinates will be written to the M5 file as shown below. The coordinates will be ignored when the file is processed by PTAGIS.

 

The fieldData element contains the GPS position information in the following comma-separated format:

Latitude,Direction(N/S),Longitude, Direction(E/W),Quality Indicator
