Wiring | NSO evo2 Installation Manual
¼ Note: If joining to an existing NMEA 2000 network that already has its own power supply, do
not make another power connection elsewhere in the network, and ensure existing network
is not powered by 24 V DC.
¼ Note: Do not connect the NMEA 2000 power cable to the same terminals as the engine start
batteries, autopilot computer, radar, bow thruster or other high current devices.
The following drawing demonstrates a typical small network. The backbone is made up of
directly interconnected T-piece joiners and an extension cable, which is terminated at each
end.

NMEA 0183 device connection
The NSO evo2 has two 2-way NMEA 0183 ports, which are connected via two discrete cables.
Each cable is dedicated to one of the two internal processors. Both the baud rate (up to
38,400 baud) and sentences output by the NSO evo2, can be confi gured. Refer to "NMEA 0183
supported sentences" on page 46 for a complete list of sentences.
1 NMEA0 183 RX_A (balanced) (brown)
2 NMEA0 183 RX_B (balanced) (brown/white)
3 NMEA0 183 TX_A (balanced) (green)
4 NMEA0 183 TX_B (balanced) (green/white)
¼ Note: The majority of NMEA 0183
devices communicate at 4,800 baud. AIS is a
common exception, and normally transmits
at 38,400 baud.
¼ Note: AIS is not internallly bridged, so
must be connected to both NMEA 0183 ports if required on both screens. AIS data supplied
via NMEA 2000 is available to both processors.
