Connect sonar transducers
As most NSS evo2 models are equipped with internal StructureScan, Chirp sonar, and
conventional sonar, the transducer(s) are usually plugged directly in to the back of the unit.
Where required, premium external sonar sources such as BSM-2, may be connected via
ethernet.

NMEA 2000 / SimNet – connection to backbone
Device connection
The NSS evo2 multi function displays 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)
