Jumper
Setting
Description
Closed
Vs of LIN B is powered by the board
JP60
(VBAT_B)
Open
No voltage supply to Vs of LIN B
Default: grey
Table 3-7: UART “C”/ LIN “B” jumper settings
3.7 CAN “A”
One high-speed CAN-transceiver can be connected to the microcontroller’s CAN interface.
JP5, JP8
connects a CAN-port to the CAN-transceiver (U2, X1).
If the CAN interface is not used then the jumpers should be left open.
