GMT00 @Track Air Interface Protocol
TRACGMT100AN001 – 28 –
range of (<Min Threshold>, <Max Threshold>), the +RESP:GTEPS alarm will be
triggered.
 <Min Threshold>: The lower limit to the voltage of the external power supply to trigger the
alarm.
 <Max Threshold>: The upper limit to the voltage of the external power supply to trigger the
alarm.
 <Sample Period>: The sampling period to measure the external power supply.
 <Debounce Time>: The time for debouncing to avoid exceptional voltage drop of the external
power supply.
 <Output ID>: ID of the output port to output specified wave shape when the +RESP:GTEPS
alarm is triggered. If set to 0, no output wave.
 <Sync with FRI>: Besides the +RESP:GTEPS alarm report, the device can also send the
voltage of external power supply periodically along with the fixed report message.
 0: Do not report external power supply voltage with fixed report message.
 1: Report external power supply voltage with fixed report message.
The acknowledgment message of AT+GTEPS command:
 +ACK:GTEPS,
Example:
+ACK:GTEPS,080100,135790246811220,,0007,20090214093254,11F0$
