SimNet network cables
A SimNet unit has one or two yellow SimNet connectors. There
are no dedicated “in” or “out” connectors. Find the shortest and
easiest way to route the SimNet cables from product to product
and select the standard length cables from the SimNet accessory
program. SimNet cables are available in 0.3 m (1 ft.), 2 m (6.6
ft.), 5 m (16.6 ft.) and 10 m (33 ft.) length all with plugs at both
ends. Connect products with two SimNet connectors in a daisy
chain and use a drop cable and T-joiner for products with only
one SimNet connector.
If you plan to extend your SimNet system in the future it may be
an idea to prepare for it by adding a few T-joiners in central
locations. The T-joiners provide easy access to the network and
can be replaced with a new product, or the new product can be
connected via a drop cable.
SimNet power and termination
The following rules should be observed when installing SimNet.
1. SimNet must not be connected to a 24VDC supply.
2. SimNet shall have a separate 12VDC power from the battery
bus or the circuit breaker board to avoid interference
3. SimNet shall not be connected to the supply voltage
terminals of the Autopilot Computer.
4. SimNet will power an IS12 instrument system. Hence
SimNet on other equipment can be connected and powered
via IS12.
5. SimNet must be properly terminated.
The SimNet network has to be terminated according to the
number and type of products connected.
In a small system consisting of maximum 5 SimNet products and
a total length of 5 m SimNet cable you only need the SimNet
power cable with built in termination (red disc on cable plug).
On larger systems you will also need a termination at the other
end of the chain.
For additional information about SimNet ask for the separate
SimNet Manual.
