Raymarine Radar Scanner manual Open array scanner cables, Systems 4 kW scanners only

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.
