4.3.1.2 Cable
The cable must have the following characteristics:
The maximum cable length depends on the baud rate used.
4.3.1.3 Termination
Terminate the CAN bus at both ends by terminating resistors (120 Ohm).
Legend for table:
I = Switch ON
– = Switch OFF
X = Any position
NOTICE
A shielded twisted-pair cable (cable type LiYCY-TP) complying with ISO 11898 must be
used.
