Radome scanner cables

Inter-unit cable

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" radome 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.

Note: For vessels with 24 V power systems, any combination of inter- unit cables can be used.

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

Note: This table applies to systems using the standard 1.5 m power cable. If you extend the power cable you may need to select different inter-unit cable(s), as discussed in the following section Power Ca- ble.
