+IN
Input
Power supply input. The power supply must be
able to meet the requirements of current
consumption. For security reason, it is
recommended to integrate externally a 2A fuse link
between power source and FOX3-KMD.

IGN
Input
General purpose input. It can be either connected
to the vehicle ignition and be used for journey
START and STOP reports, or be connected to the
operating vIN and be used to wakeup the
FOX3-KMD devices from IGN-Sleep mode
(awaking
from this mode requires a HIGH signal)

Serial Port 0 - Serial communication signals (RxA and TxA)
FOX3-KMD devices incorporates a full duplex serial channel which allows two devices to communicate directly
with each other via the RS232 serial port.
RxA_0
Main channel used to receive software commands to the board from any
software (e.g. HyperTerminal). Moreover, the firmware update can also be done
through this serial port.
TxA_0
Main channel used to output navigation, measurement, response and system
data to any software (e.g. HyperTerminal, FALCOM Workbench).
