Wiring
The IS40/Triton display can be connected to either an NMEA 2000
or SimNet network. There is no separate power cable, as the unit is
powered from the network.
There are two Micro-C connectors on each display, allowing for
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,
and is based on CAN (Controller Area Network - SAE J1939) bus
technology. NMEA 2000 permits exchange of data and commands
between the interfaced products. NMEA 2000 stipulates the use of
Micro-C and Mini-C hardware for the physical aspect of the network.
Most NMEA 2000 devices can be connected directly to the NMEA
2000 backbone and SimNet devices can be connected by using
adapter cables.
Essential network information
• NMEA 2000 is a powered network. It must have a separate 12-15 V
DC power supply protected by a 5 Amp fuse. Do not connect the
NMEA 2000 power cable to the same terminals as the start batteries,
Autopilot Computer, Radar, thruster or other high current products
• An NMEA 2000 network consists of a linear “backbone” from which
“drop cables” connect to NMEA 2000 devices
• A single drop cable has a maximum length of 6 m (20 ft). The total
length of all drop cables combined should not exceed 78 m (256 ft)
• An NMEA 2000 network has a maximum cable length of 100 m (328
ft), between any two points
• An NMEA 2000 network needs to have a terminator at each end of
the backbone. A terminator can be one of the following:
• a power cable with built in terminator
• a terminated blanking plug
• a wind transducer (terminator is in the mast head
unit as opposed to mast cable).
