8.4 Cable Runs
Consider the following before installing the system cables:
• You need to attach the power cable and the scanner 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 8.8, Integrated Systems).
• Inter-unit cable, supplied with the scanner unit. This is Vinyl-covered and
shielded, with a connector plug at one end for connecting to the display unit
or extension cable.
• SeaTalk cable, optional, with SeaTalk connector(s) at one or both ends.
• hsb 2 cable, required for multi-display systems.
• NMEA Output cable, optional, with an NMEA OUT connector at one
end only.
Power Cable
The hsb 2 series display system (i.e. with a scanner connected where
applicable) is intended for use on ships’ DC power systems rated as follows:
12 V or 24 V systems Radome Scanner System
12 V, 24 V or 32 V systems 4 kW Open Array Scanners System;
RC530/631
24 V or 32 V systems 10 kW Open Array Scanners System
A 5 ft. (1.5 m) power cable is supplied for connecting the ship’s DC power to
the display unit. Longer power cable runs may require larger wire gauges to
minimise any voltage drop in the cable. The scanner type and the length and
type of the inter-unit cable also affect the wire gauge required for the extension
power cable. For further details on the master display power cable length refer
to the Pathfinder Plus Radar Scanner Owner’s Handbook.
