CAN Bus Wiring Requirements
• The CAN bus should consist of a twisted pair trunk with 100R (0.25 watt)
terminating resistors at each end.
o If the CAN bus is less than 2 meter (7 ft) long, a single termination
resistor may be used.
• The preferred cable for the trunk is 100R data cable.
• The maximum length of the bus is 16 meter (50 ft)
• CAN devices (such as MoTeC Dash Loggers, ECUs etc) may be
connected to the trunk with up to 500 mm (20 in) of twisted wire.
