Raymarine Combined Pathfinder Radar, RL80CRC PLUS manual Inter-Unit Scanner Cable, Hsb2 Cable

Chapter 8: Installation 8-9

If a longer power cable run is required, use the supplied power cable to connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable, taking particular care to ensure correct polarity. The supplied power cable has a cross-section of 2.0 mm2.

Note: For repeater displays, the power cable may be extended by up to 20 m using a wire gauge of 1.5 mm2 (AWG 16) or greater, irrespective of the inter- unit cable length.

Inter-Unit Scanner Cable

The inter-unit (scanner) cable entrance is at the rear of the scanner unit. If the unit is mounted on a hollow mast the cable may be run inside the mast and then fed through the radar’s cable entrance. Make sure that the cable does not chafe where it enters the mast.

Note: Route the cable from the display up to the scanner, since this will re- quire the smallest clearance hole.

The type of inter-unit cable, for connecting the scanner to the display unit, depends on your scanner package. Refer to the Pathfinder Plus Radar Scanner Owner’s Handbook for details, which include length considerations and bending radii.

hsb2 Cable

The number of hsb2 (PLUS) display units that can be connected is limited by the total cable length.

For example:
10 units	Max. total cable length - 40 m
8 units	Max. total cable length - 60 m

Note: If you have fewer displays, it may be possible to have more than 60 me- tres of cable and conversely, if your total cable length is less than 40 metres, it may be possible to connect more hsb2 displays. Contact you authorized Ray- marine dealer for further details.

CAUTION:

Do not cut nor rejoin the HSB cable - this will result in signal degradation.
