2.4 Cable Runs
Consider the following before installing the system cables:
• You need to attach the power cable and the transducer cable. Additional
cables will be required if you are installing an integrated system.
• All cables should be adequately secured, protected from physical damage
and protected from exposure to heat. Avoid running cables through bilges
or doorways, or close to moving or hot objects.
• Acute bends must be avoided
• Where a cable passes through an exposed bulkhead or deckhead, a water-
tight feed-through should be used.
• Secure cables in place using tie-wraps or lacing twine. Coil any extra cable
and tie it out of the way.
You need to run the following cables:
• Power/NMEA Input cable, supplied with the display unit. This has a con-
nector plug at one end for connecting the display unit, and 7 wires at the
other end for connecting the power supply and optional NMEA inputs (see
Section , EMC Conformance).
• Transducer cable, supplied with the transducer. This 30 ft (10 m) cable
has a connector plug (with removable outer shell) at one end for the display
unit or extension cable.
• SeaTalk cable, optional, with SeaTalk connector(s) at one or both ends.
• HSB cable, optional.
• NMEA Output cable, optional, with an NMEA OUT connector at one
end only.
Power Cable
The HSB Series Fishfinder is intended for use on ships’ DC power systems
rated from 10.7 V to 32 V.
A 5 ft (1.5 m) power cable is supplied for connecting the ship’s DC power to
the display unit. The power cable may be extended by up to 60 ft (20 m) using
a wire gauge of AWG 16 (1.5 mm
2
) or greater.
