The connectors are weather proof according to IP66,
when properly installed. All unused SimNet connectors
must be tted with the plastic cap to protect them
against dirt and moisture.
SimNet power and termination
The following rules should be observed when installing
SimNet:
It must have a separate 12VDC power from the 1
battery bus or the circuit breaker board to reduce
interference
It must not be connected to the supply voltage 2
terminals of the Autopilot Computer
It will power a SimNet compatible instrument 3
system. Hence SimNet to other equipment can be
supplied via the autopilot, see the gures on page
41, 42 and 43
SimNet must be properly terminated, i.e. unless it 4
is a small system (see the gure on page 41) there
must be terminations at each end of the Simrad
backbone
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 backbone
cable, you only need the SimNet power cable with built-in
termination (red disc on cable plug).
For additional information about SimNet, ask for the
separate SimNet Manual.
