Remarks: Send this command to set sensitivity of tremble sensor.
Note:
1. XX=[1,255], it will be more sensitive if XX is smaller
2. Default value is 30.
Example: W000000,035,30
Remarks: when the heading direction of the tracker changes over the preset degree, a message with location data will be sent
back to the server by GPRS.
degree=0, to turn off this function.
degree=[1,360], to set degree of direction change.
For more information regarding GPRS tracking please refer to <GPRS Communication Protocol>
Output Control (Immediate)
F =0, to close the output (open drain)
=1, to open the output (low voltage)
For example, if you have connected Output1 with a relay, you can send W000000,020,1,1 to stop the engine.
Output Control (Conditional)
W******,120,F
W******,220,F
W000000,120,1
W000000,220,1
Remarks: This function is achievable only when the speed is below 10km/h (command 120) or 20km/h (command 220) and
meantime GPS is available.
F=0, to close the output (open drain)
=1, to open the output (low voltage)
Remarks: this setting is for power saving.
Here is some explanation for the sleep mode.
GPS module will be closed for 64 seconds * X ( X=1, 2, 3), if it gets continuous GPS fixed for 32 times or Non-GPS fixed for 128
times. After that, GPS module will periodically work and close.
Remarks: Put the tracker in power down mode when the tracker is inactive (stationary) for a period of time.
In Power Down mode, GPS stops working and GSM enters sleep mode and stop sending out messages. The device remains in
this mode until it is activated by message, incoming calls, or input changes.
XX=00, to turn off this function;
XX=01~99, to turn on Power Down after a specified period of being inactive. It is in unit of minutes.
In this example, the tracker will enter power down mode after it is inactive for 10 minutes.
W000000,032,480 W000000,032,-120
Remarks: Default time of the tracker is GMT, you can use this command to correct it to your local time. This command is for SMS
tracking only.
