Inter-Unit Cable

2D (US) 10m light (2 power cores)

2DE (European) 15m light (2 power cores)

4D 15m heavy (4 power cores)

The minimum bends permitted are:

Minimum bend, light cable 60 mm (~2.5 in) radius

Minimum bend, heavy cable 82 mm (~3.75 in) radius

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 minimise voltage drops over

the longer cable run: these optional cables include 5m and 10m extension

cables, and a 25m 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 24V power systems, any combination of inter-unit

cables can be used.

For vessels with 12V power systems, the recommended cable(s) for different

run lengths are given in the following table, which assumes a minimum supply

voltage of 10.7V (the lowest voltage likely to be reached by a 12V battery in

normal marine use). Do not use cable combinations that are not included in

the table.
