Appendix H: CAN Wiring

The CAN bus should consist of a twisted pair trunk with 100R (0.25Watt)
terminating resistors at each end of the trunk.

The preferred cable for the trunk is 100R Data Cable but twisted 22# Tefzel is
usually OK.

The maximum length of the bus is 16m (50ft)

CAN Devices (such as MoTeC ADL2, BR2 etc) may be connected to the
trunk with up to 500mm (20in) of twisted wire.

Note that the “CAN Cable Connector” is not normally used since the ADL2
uses USB for communications.
