8.1 Schematics
The figure below illustrates a common schematic when you install your DISCO-B4-GLONASS
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-GLONASS 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
po
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-GLONASS
unit from the vehicle body. Do not connect power from a different system to the
DISCO-B4-GLONASS.
Software configured outputs of the DISCO-B4-GLONASS 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-GLONASS (+IN) and d.c. -
power source.
The device should be mounted
on an exterior flat surface of a vehicle such as
the roof with the GPS side (top side) facing the sky.
Connect the power cable to the DISCO-B4-GLONASS.
With the vehicle ignition off and
antenna connected, attach the power pins to DISCO-B4-GLONASS (FIRST connect the
GND pin and then the +IN pin).
