Radome scanner cables

Inter-unit cable

The radome inter-unit cable is fitted with an 8-way plug and power cores (covered
by a clear protective sleeve) for connecting to the scanner.
The length of the supplied cable should be sufficient to complete the cable run
required on most small vessels. For longer runs, additional or replacement cables
are available, which have 4 power cores to minimize voltage drops over the
longer cable run: these optional cables include 5 m and 10 m extension cables,
and a 25 m replacement cable.
The maximum inter-unit cable length is limited by the minimum supply voltage,
the scanner type (18" or 24" radome), and the cable type (2 or 4 power cores): if
a mix of light and heavy cables is used, only 2 power cores are connected through.
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.
Notes: (1)
can be used.
This table applies to systems using the standard 1.5 m power cable. If you
(2)
extend the power cable you may need to select different inter-unit cable(s),
as discussed in the following section Power Cable.
