6/5-wire cabling
In case of limited systems, a 5-wire cabling suffices. In that case, the M terminal does
not have to be wired. All jumpers then have to be set to 5-wire cabling.

Image quality - amplification
TIP: Preferably adjust the image clarity with 2 people: one to control the controller and
one to check the image quality on the video internal units.
Note: Due to signal attenuation in the video bus (V1, V2) after splitting, the brightness of
the image can decrease. Turn the control by means of a screwdriver to adjust the image
