3 INSTALLATION
SimNet is very easy to install but to get the best and most
reliable result you should use the following guidelines and plan a
little ahead of starting to route and connect the cables.
Simrad can provide you with a range of SimNet accessories that
will make your installation easy and professional looking (page
44).
3.1 Planning the installation
First, determine the best location on the vessel to mount the
SimNet products, and other products only equipped with
NMEA0183 interface. Due to SimNet’s flexibility you need not
take any particular precautions when placing the products.
You may connect each NMEA0183 product to SimNet via the
AT10 Universal NMEA0183 Converter (single input and output)
and the Simrad IS15 instrument system via the AT15 SimNet
converter. You will find these as part of the SimNet accessory
program (page 44).
Some of the SimNet products have a built in NMEA0183
converter function that will make selected data available to and
from SimNet, but be aware of the limitations it may imply. (See
Appendix 1, page 38, for more details).
Note ! On the autopilots the NMEA0183 ports are not on the control
units and you have to plan with this in mind if you are not using
AT10 as interface. The NMEA0183 connections are described in
the autopilot manual.
3.2 Select the SimNet accessories you need
1. Find the shortest and easiest way to route the SimNet cables
from product to product.
2. Determine the required amount of standard cables and other
accessories from the SimNet accessory program; keep cables
as short as possible. If you plan to extend the SimNet system
at a later stage, it might be useful to add a few T-joiners in
appropriate locations for easy access to the network. They
