UMPERS
Two 2mm jumpers are required per CAN interface due to the split termination (V1 dual jumper
for CAN Port 0 and V2 dual-jumper for CAN Port 1). The jumpers are installed to enable split-
termination. The following are the jumper states for the V1 positions on Port 0 and V2 jumper on
Port 1.

Note:
The jumpers can be removed and bypassed (using 0-ohm 0402 resistors) for jumper-less
operation. The split termination capacitor can be removed if split-termination is not desired.
