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 guage of 1.5 mm
2
(AWG 16) or greater, irrespective of the inter-
unit cable length.
Inter-Unit Cable
The inter-unit 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 Radar Scanner
Owner’s Handbook for details, which include length considerations and
bending radii.
Note: If your color LCD display part of a system with a 10.4" LCD/10” CRT
display, the radar scanner must be connected to the 10.4" LCD/10” CRT dis-
play to enable the MARPA functionality.
