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.

 cable, required for multi-display systems.
NMEA Output cable, optional, with an NMEA OUT connector at one 
end only.
Power Cable
The 
hsb

 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.
