8.1 Schematics
The figure below illustrates a common schematic when you install your DISCO-B4
hardware in the vehicle and use it for vehicle security. For detailed information,
please, refer to the related documents [
InVehicleMounting.pdf
].
8.1.1 Installation guidance for 8-pin connector
On the top of the schematic you can find the corresponding pin out of the 8pin
double row connector.
When installing your DISCO-B4 you will not only be able to track and locate objects
all the time, but you will
also
be automatically notified when disagreements occur
between the configuration and device behaviours
themselves
. Depending on your
application requirements, the I/O pins can be configured and used as digital
outputs to lock/unlock vehicle doors, to activate a relay, buzzer, turn on a lamp
;
or
as digital inputs to detect when something in the vehicle is opened or closed. Input
changes may trigger an output to high or low. The IGN line can be connected to
the vehicle ignition key to monitor its
ON/OFF
position.
Note:
Turn car ignition off before making any connection. Use a common ground
point for all ground wires. To avoid ground loops, isolate all ground pins of
the DISCO-B4 unit from the vehicle body. Do not connect power from a
different system to the DISCO-B4.
Software configured outputs of the DISCO-B4 must operate at the same
voltage level as the supply vIN operates.
The operating voltage range must
NEVER
be exceeded as device is not
protected again continuous overvoltage. For security reasons it is
recommended to integrate externally a 2A fuse link between the positive
wire of the DISCO-B4 (+IN) and d.c. - power source.
The device should be mounted
in the dash or on the windshield of the vehicle
with the GPS side facing the sky and the antenna has a clear view to the sky.
Connect the power cable to the DISCO-B4.
With the vehicle ignition off and
antenna connected, attach the power pins to
DISCO-B4 (FIRST
connect
the
GND
pin and then the
+IN
pin).
