NMEA 2000
NMEA 2000 device connection
All models of Zeus Touch are equiped with an NMEA 2000 port, which allows the receiving
and sharing of a multitude of data from various sources.
Essential network information
• A NMEA 2000 network consists of a linear “backbone” from which “drop cables” connect to
NMEA 2000 devices
• NMEA 2000 cables used for B&G products are of the ‘micro-c’ style, which is a cable/connec-
tor specifi cation approved for use in NMEA 2000 certifi ed networks. Some B&G products use
SimNet proprietary connectors, but are compatible via adaptor cables.
• A single drop cable has a maximum length of 6 m (20 ft). The total length of all drop cables
combined should not exceed 78m (256 ft)
• A NMEA 2000 network has a maximum cable length of 100 m (328 ft), between any two
points
• A NMEA 2000 network needs to have a terminator at each end of the backbone. A terminator
can be one of the following:
• a terminator blank plug
• a wind transducer (where the mast cable is one end of the backbone)
Planning and installing a network backbone
The NMEA 2000 backbone needs to run between the locations of all products you want to
install, typically in a bow to stern layout, and be no further than 6 m from a device to be con-
nected.
Choose from the following components to make up your NMEA 2000 backbone:
• Micro-C cables: 0.4 m (1.3 ft), 2 m (6,6 ft), 5 m (16.6 ft), and 9 m (29.5 ft) cables
• Micro-C power cables with or without termination
• T-connector. Use at locations where you want to connect a device by drop cable
 Note: If using a wind sensor, the mast cable should be connected as the fi nal length of cable
in one end of the backbone, as the sensor is fi tted with a termination resistor.
 Note Most NMEA 2000 devices can be connected directly to a Simrad SimNet backbone and
SimNet devices can be connected to a NMEA 2000 network by using adapter cables. (see ‘Ac-
cessories’ page 57)
 Note: The Zeus Touch has a Micro-C NMEA 2000 connector but is fully compatible to work in
a SimNet network by using an adapter cable.
 Note Triton displays have two connectors, and can either be connected inline with the back-
bone, or wired individually off a drop cable. Connecting from device to device is known as
‘daisy chaining’ This network topology is not offi
cially NMEA 2000 compliant.
