5.10 Restart device
If GPRS is abnormal (device is offline), user can send SMS
command
to restart the device. Device will reboot after 20
seconds after receive the command.
RESET#
(See command list 7-16)
5.11 Door detection
The device is able to detect door status. It uploads car status to
platform and APP timely. Negative triggering is default. When car
door's status is negative triggering, there is no need to set. Instead,
if car door status is positive triggering, the triggering way has to be
modified. (Command: DOOR,1#). See 3.3 diagram-2 for wiring way.
(
Notice
Negative triggering (default): when door is open, signal level of door
is 0V; when door is closed, signal level of door is power voltage.
Positive triggering: when door is open, signal level of door is power
voltage; when door is closed, signal level of door is 0V.
See command list 7-17)
5.12 Analog signal
The device can measure car battery's voltage and upload it to
platform/APP in fixed time based on your needs. Purple line (ADC)
of device extended port can receive analog signal, like voltage of
external device, analog temperature sensor and fuel sensor. Voltage
range of analog input is 0~30Vdc. See 3.3 diagram for wiring way.
(See command list 7-18)
5.13 Find the car by triggering
light and buzzer
When need to pick out the car parking on giant parking lot, you can
send a command. After the device receives the command, it will
control turn light relay or horn relay by the yellow line of extended
port, so as to trigger the car's light or horn. In this way, you can figure
out your car's position easily and accurately. See
for
wiring way. (See command list 7-19)
