Open array scanner cables for Pathfinder displays
Inter-unit cable
The Pathfinder display inter-unit cables have a connector plug at one end for
connecting to the display unit or extension cable; the other end is prepared ready
to fit to the power and signal connectors (see
Section 2.2 ).
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 Raymarine 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.
