Note
Power will need to be supplied to the sonar head through pin 3 (for example
24V DC supply for a SeaKing) and pin 4 (0V ground) of the Tritech connector -
the ARCNET port will not be able to supply this power and a suitable external
source should be used.
SeaKing Sensor(s) in ARCNET through Fiber Optic Interface
It is possible to connect a standard ARCNET system through Fiber, allowing multiple heads
without the need for a stand alone AIF card or Junction Box
The connection to the SCU should be made through the ARCNET (DA-15) port and wired in
the same manner as the
ARCNET Through Twisted Pair
shown above.
