Remember:
1. The 30 m (99’) wind sensor cable should not be included
in the SimNet cable length (L) calculation.
2. The length of the power cable should be accounted for in
each branch calculation. Make sure you include the total
length of cable all the way to the battery. (See paragraph
3.3 for instructions on how to reduce the effect of an
extended power cable length)
Since all SF (L • NL) values are within the maximum limits this
system will perform to specifications.
Extra large Systems (SF > 2000)
Making an installation of an extra large network is more
complicated, and outside the scope of this manual.
If you are planning to install an extra large system, please
contact your local Simrad representative for assistance.
Connecting SimNet products to a
NMEA2000 network
SimNet products can operate on a NMEA2000 network.
To connect a SimNet product to an existing NMEA2000
network (backbone) you must use only one
single SimNet to
Micro-C (drop) cable P/N 24005729 and connect it to a free
NMEA2000 Tee joiner (Micro-C connector).
Note ! Daisy chaining of products must not be made on a NMEA2000
network. Whenever SimNet and NMEA2000 products are
interconnected, the NMEA2000 cable system must be used and
the NMEA2000 installation guidelines must be followed.
