4.2.3 Activation with GPS I/O (P/N 2798.4 Only)
The TerraFix™ 406 GPS I/O is also equipped with an Onboard GPS receiver. Once activated the
TerraFix™ 406 GPS Onboard GPS engine will start up and search to find your LAT/LON and
incorporate it into your 406 MHz signal. In the case when external and internal GPS are present, the
internal GPS data will have priority at activation.
When the TerraFix™ 406 GPS I/O is turned ON, the GPS Onboard receiver is also immediately
turned ON and will immediately begin acquiring data. As soon as the GPS receiver acquires good
positioning data the red LED will stop blinking and the green LED will begin flashing once every 2
seconds. Once good global positioning data has been obtained, the GPS receiver waits for 20
minutes before looking for new positioning data again. If for any reason a time period of 4 hours
passes without the GPS receiver being able to update the last good set of GPS coordinates, the
message transmitted by the TerraFix™ 406 GPS I/O will revert to default data. At this point the
green LED will stop blinking and the red LED will flash once every 2 seconds. If at any time after
this, good GPS data is obtained, this data will be transmitted, the red LED will stop blinking and the
green LED will begin flashing again.
