9.1 Schematics
The figure below illustrates a common schematic when you install your DISCO-B5-MAGNET
hardware and use the provided input/output pins. For detailed information, refer to the
manual [
InVehicleMounting.pdf
].
9.1.1 Installation guidance when using the I/Os on the 8-pin socket
On the top of the schematic you can find the corresponding pin out of the 8pin female socket.
When installing your DISCO-B5-MAGNET 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
is opened or closed. Input change events can be used to trigger an output to high or low.
Note:
When installing the device in a vehicle, 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-B5-MAGNET unit from the vehicle body.
When charging the battery, do not connect power from different systems to the
DISCO-B5-MAGNET.
The input 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-B5-MAGNET
(+IN) and d.c. - power source.
To charge the internal batteries connect the power cable to the DISCO-B5-
MAGNET.
With the vehicle ignition off attach the power pins to DISCO-B5-MAGNET
(FIRST connect the GND pin and then the +IN pin).
