The cable screen must be connected to the housing
on the transducer plug.
Note
The black wires in the transducer cable are not for
grounding. You must never connect these together,
and you must not connect any of them to vessel ground.
Cable screen must not be connected to vessel ground.
If you need to cut or lengthen the transducer cable, you
must splice it correctly. This is very important, as any
splice is very vulnerable for noise.
Cable can be spliced by two different methods:
• Splicing using a grounded junction box
• Splicing using a junction box that is isolated from vessel’s ground
Refer to the dedicated procedures.
We strongly recommend that you install the transducer cable in a steel conduit.
Note
The software license controls how the transducer is connected to the transceiver. The
License Details
text box explains which transceiver channels that are used. Each channel
available is listed with the relevant operational frequency and power capacity. For more
information, refer to the context-sensitive on-line help.
Minimum cable requirements
Not applicable. If you need an extension cable, contact your dealer (or Kongsberg Maritime)
for support.
