2.5 Cable Extension Kit
The length of the cable between the hull unit and transceiver unit is 5 meters. If a longer
cable is required, use the cable extension kit, which consists of a junction box and a 5 or 15
meter cable.
Connect the transducer cable 10S2223 to the junction box, and connect the transceiver unit
to the junction box with the cable 10S2240 (5 or 10 m).
Replace the cable (10S2078, 8 m) connected between the hull unit and transceiver unit with
the cable 10S2144 (12.9 m) or 10S2145 (22.9 m). Those cables are supplied with the
extension cable kit.
2.5.1 Junction box
Connect the extension cable 10S2240 to JCTN1 and JCTN2 inside the junction box. Also,
connect the transducer cable 10S2223. Refer to interconnection diagram for wiring details.
