CAN bus

The CAN bus is based on the well known SimNet plug & play concept and on the NMEA 2000
(N2K) SAE J1939 protocol. Hard wiring is based on standard NMEA 2000 cables with Micro-C
type connectors and joiners.
The bus consists of a linear backbone using drop cables and Micro-C T-joiners for connecting
NMEA 2000 and SimNet devices.
The bus has a maximum cable length of 150 m (500 ft), and a drop cable has a maximum
length of 6 m (20 ft).
In a default MX610/MX612 system the CAN bus backbone expands from the MX610JB, which
supplies power to the backbone. There will always be a female connector in the expanding
end of the backbone cables.

Planning and installing a network backbone
• Plan the network carefully
-
It is recommended to create a diagram of the network prior to starting the installation
• Run the backbone between the locations of all CAN devices you want to install
-
It must be less than 6 m (20 ft) cable run from a device to the backbone
• Consider the load/current draw from the devices
