How to ground the main unit
• Use a 1.25 sq wire (local supply) for the ground wire.
• Make the length of the ground wire as short as possible and connect it to the boat's
ground.
• For FRP vessels, attach a steel plate measuring 20 cm by 30 cm on the outside of
the hull to provide a ground point. Connect the ground wire there.
Note 1: Use a ring-type lug (
a fork-type lug (
Note 2: External equipment should not be connected to the fish finder if the signal
ground of the external equipment and the positive DC terminal of the fish finder are
connected to the boat's ground.
Connection of the power cable inboard
Connect the power wire of the power/data cable to the vessel power supply (12-24
VDC).
Connection of NMEA0183 and external KP devices (FCV-800 only)
Connect the signal wires of power/data cables used for NMEA0183 (navigation de-
vice, wind sensor) and external KP.

Transducer cable connection
For FCV-600, connect the transducer cable to the [XDR] port.
For FCV-800, the type and combination of transducer determines the port to which the
transducer cable is connected.
Note: Supply voltages are different depending on XDR ports. Be sure to connect each
transducer to the correct port (see the table below).
CW transducer connection only.
