Diagram G – Videophone Local Power Wiring
Where more than one extension video unit is required to provide "auto display" then
additional power supplies will be required
Note. For each cable run :-
Only one unit must be Master (Recommend the first unit)
Extension video units must be "daisy chain" wired to preserve video quality
The last (or only) video unit on the cable requires the Video Terminator "ON"
all other video units must have the Video Terminator "OFF"
