851-165187 / Rev.A
Only one hydrophone can be connected at any one time.
However, by means of manual or automatic switches, you can
connect two hydrophones to the system. If your vessel performs
both trawl and purse seine fishery, you can even install two sets
of hydrophones, and switch between these.
Each hydrophone is supplied with approximately 22 meters of
cable. Since the plug is too large to penetrate most cable glands,
the cable has been cut 3 meters from the plug. In order to splice
the cable you will need a metal junction box. A suitable box
may be ordered from Simrad, or you can manufacture or
purchase one locally.

C7 - Echo sounder transducer
You can connect one or two echo sounder transducers to the
PI54 Operator Unit. Two sockets are provided on the rear side;
Echo1 and Echo2. Which of these to use depend on the chosen
transducer(s).

The following specific connection diagrams have been provided
for common transducers.

C8 - Echo sounder transducer
Refer to the cable description provided for C7.
C9 - Speed log
An external speed log may be connected to the Echo1 socket. If
you also have an echo sounder transducer connected to Echo1,
you will need to use an external junction box to accomplish the
wiring.

C10 - Temperature sensor
The echo sounder transducers recommended for use with the
PI54 all have a built-in water temperature sensor. If you use a
different transducer - without such a sensor - you can connect a
separate temperature sensor to the Echo2 socket. If you also
have an echo sounder transducer connected to Echo2, you will
need to use an external junction box to accomplish the wiring.
