Between terminals ...
b and a
b and P
M and P
B and V1 or V2
2. If the problem with the unit is not solved, then go through the following list of possible problems:

The following voltage must be present
± 24 Vdc
± 24 Vdc
± 24 Vdc
± 5 Vdc
Cause
adjusted.
The wires on terminals V1 and V2 have been
reversed.
Incorrect cable:
The cable distance is too big
•
• The cable is eroded;
•
The cable cross-section is too small
•
It is not a twisted cable.
•
The gain on the splitters is not set correctly.
There is too much backlight.
The wiring is not correct:
Terminal M or P is not connected.
•
Terminal V1 or V2 is not connected.
•
Solution
Rotate the camera until the image is horizontal.
Connect the wires correctly to terminals V1 and V2.
Replace the current cable with a suitable cable.
Adjust the gain on the splitters with the
potentiometers.
Adjust the camera settings (in the menu).
Check the wiring against the wiring diagram.
