Note:
1) baud rate selectable by two jumpers
2) The CAN connection consists of a cable with twisted pair (both
shielded and not shielded). The first and the last elements of the
system must have the bus terminating resistor connected (impedance
is 120
Ω
). A second twisted pair is used for the feed and the ground
