can later be replaced by a new product, or the new product
can be connected via a drop cable – quick and easy!
3. Note the product(s) that will need a NMEA0183 to SimNet
converter (AT10 and/or AT15).
4. Use the SimNet cable gland for an attractive and protected
bulkhead or panel feed through.
5. Use the SimNet Bulkhead Tee connector to make a solid and
protected SimNet outlet, e.g. for remote controls.
6. Use the standard SimNet T-joiner to connect products that
are bracket mounted (or have only one SimNet connector).
This will prevent a break in the network cable (backbone) if
the product is removed. Alternatively the Bulkhead Tee
connector can be used.
Note ! The SimNet IS12 wind sensor is supplied with a special 30 meter
light weight cable. This cable must not
be used as an ordinary
network cable.
3.3 SimNet power and termination
Power connection and network protection
A separate DC power supply to the network backbone is
necessary to operate the network. A solid connection to the ships
battery or other stable DC supply source is essential to the
installation (See specifications, page 11). It is recommended to
include a circuit breaker or switch and a 5 A slow blow fuse in
series with the battery + wire. The fuse is to protect the SimNet
plug and cable system in case of a short-circuit.
Caution ! Do not connect SimNet to a 24V battery. Observe the battery
polarity. – Wrong polarity and voltage will damage products
connected to SimNet.
