The connection of the apparatus is of the unpolarised type.
The use of conductors with characteristics other than those
prescribed does not guarantee certain system distances being reached or the good quality of the video signal, therefore only
use the cables described in the tables below.

In case of multipaired cable, it is advisable to use one pair only for the system. If necessary to reduce voltage drop, due to long distances,
it is possible to use a pair as a single core.
**
In case of multicore cable, it is necessary to use only two of the available wires. We recommend not to double up on the conductors.
