4. TROUBLESHOOTING
In case of problems, always first check with a multimeter whether the following voltages are present:
• Between b and a: approx. +24VDC
• Between b and P: approx. +24VDC
• Between M and P: approx. +24VDC
• Between M and V1 or V2: approx. + 5VDC
A list of possible problems with their causes and remedies is given below.
Problem
The image on the video internal unit is not hori-
zontal.
The image on the video internal unit is not clear. Conductors V1 and V2 have been reversed.
No image on the video internal unit. The other
functions work OK.

Cause
The orientation of the camera is not set cor-
rectly.
Cable is unsuitable:
• Cable distance is too great.
• Cable is eroded;
• Cable cross-section too small;
• Cable is not a twisted pair cable.
The gain on the splitters is not set correctly.
Wiring is not connected correctly:
• M or P missing
• V1 or V2 not connected
