The B&G Triton Display can be connected to either an NMEA2000
or SimNet network. There is no separate power cable, as the unit is
powered from the network.

daisy chaining, which greatly increases the ease of connecting
multiple displays that are in close proximity, and can save in cable
weight and loom size. Note this method is approved in SimNet
networks, but not in NMEA 2000 networks.
Introduction to NMEA 2000 (SimNet)
NMEA 2000 is a combined electrical and data specification,
andisbasedonCAN(ControllerAreaNetwork-SAEJ1939)bus
technology. NMEA2000 permits exchange of data and commands
between the interfaced products. NMEA2000 stipulates the use of
Micro-CandMini-Chardwareforthephysicalaspectofthenetwork.
SimNet is largely based on NMEA2000, but with added proprietary
messages, and it’s own physical cable and connector system. The
data transfer capacity of NMEA 2000 is 50 times higher than that of
theNMEA0183standardat4800baud.
Most NMEA2000 devices can be connected directly to a SimNet
backbone and SimNet devices can be connected to an NMEA
2000 network by using adapter cables. The physical layout and
limitations of the two networks are nearly identical, so the following
information is interchangeable.
