8-12 SL72 & SL72RC PLUS Pathfinder Radar & Radar/Chartplotter
Inter-Unit Scanner
Cable
Note: If you have an 18" radome scanner, and the wire gauge required for
your extended power cable is unacceptably large, you should replace the sup-
plied light (2 power core) inter-unit cable with the 25 m heavy (4 power core)
inter-unit cable assembly (see table).
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.
CAUTION:
The display connector on the inter-unit cable is a moulded plug that
cannot be replaced. DO NOT remove this moulded plug.
The inter-unit cable, for connecting the scanner to the display unit, depends on
your scanner package as follows
