power cable. For further details on the master display power cable length refer
to the
Pathfinder Plus Radar Scanner Owner’s Handbook.
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 mm
2
.
Note: For repeater displays, the power cable may be extended by up to 20 m
using a wire gauge of 1.5 mm
2
(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.

Cable
The number of
hsb
2
(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

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.
