10.8 Basic transducer and cable information
The installation should be carefully planned in advance, keeping in mind the
standard cable length of 10 meters (32 feet) which is connected to the trans-
ducer. In the event where the standard cable is not long enough, up to an addi-
tional 10 meters (32 feet) may be connected without a noticeable reduction of
the performance. The cable must be of the same type as the standard cable.
The CE33 must be turned off while connecting/disconnecting the trans-
ducer cable.
The use of longer cable runs, while possible, always increases the likelihood of
increased interference and decreased performance. Care must be taken when
increasing the cable lengths to ensure that proper, adequate and consistent
shielding is maintained, that cable of adequate cross section is used, and that
all connections are properly made and protected from the effects of the marine
environment.
If possible, running the transducer cable through a grounded conduit will
greatly decrease the likelihood of interference. Likewise, the transducer cable
should be run as far as possible from other electrical cabling. If it is absolutely
necessary to pass close to other cabling, it is best to keep as much distance as
possible, and to make all crossings as close to a right angle as possible.
