Attach the 7 pin female connector on the Y-cable to the sounder module,
and then attach the transducer cable to the 3 pin male connector on the Y-
cable.
•
Depth-only
transducers have a 7 pin female connector.
Attach the transducer cable connector directly to the sounder module.
•
If being installed in conjunction with a speed/temperature transducer,
attach the Y-cable’s 7 pin female connector to the sounder module, and
then attach the transducer cable to the 7 pin male connector on the Y-cable.
Note:
If your system requires both a Y-cable and a transducer extension ca-
ble, ensure that you connect the Y-cable to the sounder module and the exten-
sion cable to the transducer.
The connector pins are shown in the following diagram, together with the
connections and wire colors. This information is provided as an aid to fault
diagnosis.
WARNING:
Do not cut the transducer cable or remove the connector.
Do not try to shorten or splice the cable.
Cutting the transducer cable will severely reduce sonar performance.
If the cable is cut, it must be replaced—it cannot be repaired.
Cutting the cable will also void the warranty.
