Connecting cables
Cable requirements
The following requirements apply to the cables used with the Terminal
Control Unit. Before using the Terminal Control Unit for the first time,
check that all cables are correctly wired and fastened.
CAN cables
The CAN cables must meet the requirements in the NMEA 2000 standard.
When connecting the CAN backbone, be aware of the following
requirements:
• The CAN bus must have a termination resistance at both ends of the
CAN backbone. If you are using a SAILOR 3027 mini-C Terminal, it is
already terminated with 120 internally. You must provide the
CAN bus with a termination resistance of 120 Wat the other end
of the CAN backbone, either with a separate termination resistance or
inside the last device on the CAN backbone. The Terminal Control Unit
has an internal 120 resistor which can be disconnected by removing a
jumper (see 120 Ohm termination for CAN interface on page 17).
