Cable can be cut to length on location. It is recommended that at least 3 feet (1 meter) extra cable length
be coiled at the Power Module if cutting to length.
Dry End Preparation
Connections to the dry end of the Transducer Module Connection Cable are made inside the Power Module.
The rack mount Power Module has a removable access panel on the top of the chassis towards the rear of
the unit. Removal of this panel allows access to the Power Module's cable interface as well as its ROM. On
the bulkhead mount version of the Power Module, the entire top pannel can be removed for access.
After passing the Transducer Module Connection Cable through the cable gland, the cable should be
prepared as shown in the figure. The urethane jacket and braided shield should be removed about 7.5"
(19 cm) from the end of the cable. This will expose the bundled wires. Be sure not to damage the internal
conductors. The Cat-5 cable to the bridge should be prepared for a standard Ethernet connection. Note that
all of the conductors from the Transducer Module Connection Cable will fit through the gland even with the
BNC and RJ-45 connectors installed.

Terminating the Cat-5 Cable
Standard T568B wiring should be used for the Cat-5 cable coming out of the Transducer Module Connection
Cable bundle. It is recommended that the Ethernet cable used to connect the Power Module to the bridge be
a standard straight-through cable also using T568B wiring. Use standard RJ-45 connectors on this cable.
These connectors are not supplied by FarSounder.
Terminating the Coax Cable
The coax cable is terminated with a standard BNC crimp style connector. There are many varieties of
these connectors depending upon the particular cable specifications. FarSounder supplies a BNC connector
