Wiring | NSO-II Installation Manual
Touch screen control
The NSO-II may be controlled solely by touchscreen displays. Support is included to
interface with the MO-16, MO-19, and MO-24, and KEPMGB-15T but other screens may
also work, though no offi cial support can be off ered. The MO series monitors require RS422
communications protocol, however the ports can also be confi gured to output RS232 for
monitors requiring this protocol. The KEP monitor control is connected via USB. Each USB port
relates to one of two screens on the NSO-II. Naturally USB 1 relates to HDMI 1 OUT, and USB 2
relates to HDMI 2 OUT.
Connection to MOL series displays
Refer to the documentation supplied with
the MOL series display to identify correct
termination of the RS422 interface.

NMEA 2000 / SimNet
Device connection
The NSO-II Marine Processors are equiped with an NMEA 2000 data port, which allows the
receiving and sharing of a multitude of data from various sources.
Essential network information
• The standardised physical cables/connectors for NMEA 2000 are ‘Micro-C’ and ‘Mini-C’,
directly derived from the automation industies ‘DeviceNET’ - ‘Micro-C’ being the more
commonly used size.
• While most Simrad products use ‘Micro-C’ cabling and connectors, some products still use
proprietary ‘SimNet’ connectors, which are easily made compatible via adaptor cables.
• A network consists of a linear ‘backbone’ from which ‘drop cables’ connect to NMEA 2000
compliant 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 78m (256 ft)
• A NMEA 2000 network, using Micro-C cabling, 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 Micro-C backbone needs to run between the locations of all products to be installed -
typically in a bow to stern layout - and be no further than 6 m from a device to be connected.
Choose from the following components to make up the 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
• T-connector. Used to connect a drop cable to the backbone
• Micro-C power cables. Connected to backbone via a T-connector
¼ Note: When 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.
