Transducer
Separate the transducer cable well away from power cables to prevent interference.
Connect the cable to the transducer connector at the rear of the display unit. Fabricate the
cable as below.
Note 1: For connection of dual-frequency transducer, use cable assy.
NCS255AD-254P-L500 (option).
Note 2: Do not connect the transducer of 38 kHz or lower to the high frequency connector.
Note 3: FCV-1100L cannot accept the transducers of 54 – 64 kHz, 112 – 122 kHz and 171
– 181 kHz.
Power cable
This video sounder is designed to be powered with 12-24 VDC power. Use the cable assy
MJ-A3SPF0013-035 (supplied as installation material).
Ground
The display unit should be grounded to prevent mutual interference. Connect an earth wire
(2 sq, local supply) between unit and ship's superstructure to ground. The length of the
earth wire should be as short as possible.
