9. Operation
Once power is applied to the M7 GX, the internal GPS will
begin to try to lock onto the GPS satellites.
The two LEDs on the front of the M7 will begin to alternately
blink red back-and-forth every second.
After 10 to 60 seconds, depending upon the satellite
strength, the red alternating blinking will stop. This indicates
the internal GPS receiver is locked onto GPS satellite
signals, and has a position fix.
The M7 GX will only transmit if it has GPS lock. If the GPS
antenna is broke or obscured, the unit will not report
position or status.
When it is locked to GPS, it will transmit its position and
status at the interval programmed into the
TXRATE
parameter.
Refer to the
M7 GX Technical Manual
for details on all of
the events that will trigger a transmission.
At the interval set by the TXRATE, you will see each
transponder’s STAT LED blink red when it transmits its
position.
At the unit used to receive position reports, you will see the
STAT LED blink green when it receives a signal over the
radio channel. The receiving station will output the received
position report using its RS232 serial port. The message
format that the postion report is sent out the serial port
depends upon the GPS mode of the unit. If it is in
GPS 2
mode, it will output it in the
PRAVE
format, which is the
format used to communicate with the
RavTrack PC
AVL
software program.
