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$
