Serial Number 4 0000～FFFF

Tail Character 1 $ $

 <Analog Input ID 1

～

2>: The analog input port ID.

 <Mode>: Working mode of the analog input alarm (+RESP :GTAIS).

z 0: Disable analog input alarm.

z 1: Enable analog input alarm. If the current input voltage is within the range of (<Min

Threshold>, <Max Threshold>), the alarm will be triggered.

z 2: Enable analog input alarm. If the current input voltage is outside the range of

(<Min Threshold>, <Max Threshold>), the alarm will be triggered.

 <Min Threshold>: The lower limit to the voltage of the analog input port to trigger the

alarm.

 <Max Threshold>: The upper limit to the voltage of the analog input port to trigger the

alarm.

 <Sample Rate>: The sampling period of the analog input port.

 <Output ID>: Specify the ID of the output port (1 to 3) to output specified wave shape when

the analog input alarm is triggered. If set to 0, no output wave.

 <

Output Active>: set the final status of the output port.

z 0: Disable status.

z 1: Enable status.

 <

Toggle Times>: The times of the square-wave.

 <Sync with FRI>: The device can send the analog input voltage periodically along with fixed

report message. Set this field to 1 to enable it, 0 to disable.

The acknowledgment message of AT+GTAIS command:

¾ +ACK:GTAIS,
