4.3 The CAN backbone
When connecting the CAN backbone, be aware of the following requirements:
• The CAN bus is already terminated with 120

inside the GMDSS Terminal.
You must provide the CAN bus with a termination resistance of 120

at
the other end of the CAN backbone, either with a separate termination
resistance or inside the last device on the CAN backbone.
• The cable length from each device to the CAN T-connector must be
maximum 6 m.
• The total length of the backbone must be maximum 200 m.
• The distance between the GMDSS Terminal and the power supply must be
maximum 55 m.
• Make the ground connection to ship ground (hull) at the power supply -
and only there.
• Connect the shield of the CAN cable to the connectors throughout the
system, but only connect to ship ground at the power supply.
