Mixing Panel
JST BM26B-PUDSS-TFC type
This connector offers the power supply, ignition control, logical inputs/outputs, the USB and +5V
power supply for the mixing panel, CAN interface, and specific inputs for dead reckoning GPS
operation.

Vehicle Interface discrete input stages
Concerns the following inputs: REVERSE and ODOMETER
By default, detection occurs when the inputs are grounded. A low impedance load connected to
ground is equivalent to grounding of the vehicle interface input.
To detect a positive voltage, the board is equipped with a zone for jumper E26 and E27 (see
CONFIGURATION chapter).
