Raymarine Radar Scanner - Manual (Page 24)

16 Pathfinder Radar Scanners
Open array scanner cables
Inter-unit cable
Heavy duty cables are available in 15 m and 25 m lengths which
should be sufficient to complete the cable run required on most small
vessels. For longer runs, 5 m and 10 m extension cables are available,
both have 4 power cores to minimize voltage drops over the cable run
and incorporate in-line moulded plugs.
The maximum inter-unit cable length is limited by the minimum
supply voltage and the scanner type.
CAUTION:
10 kW scanner systems cannot be used directly with 12 V
systems; they require a 12 V to 24 V converter rated to 180 W.
Contact your authorized Raytheon dealer or distributor for
details.
12 V Systems (4 kW scanners only)
For vessels with 12 V power systems, the recommended cable(s) for
different run lengths are given in the following table, which assumes
a minimum supply voltage of 10.7 V (the lowest voltage likely to be
reached by a 12 V battery in normal marine use). Do not use cable
combinations that are not included in the table.
Refer to the packing list in Section 1.2 for cable part numbers
24 V and 32 V Systems - 4 kW scanners
For vessels with 24 V and 32 V power systems, any combination of
inter-unit cable up to a maximum length of 35 m can be used.
