Re: [CAD_CAM_EDM_DRO] Re: Thanks all for the information on the Allen Bradley Monitor

I have no idea what this monitor looks like, but if it's a generic type
older monitor it would have;
+15V (12 to 15V)
Video (1V p-p)
H sync (TTL)
V sync (TTL)
Gnd

You really need a scope to see what's what. If you can find a single
connector on the board with signals as above, you should be on your way.
Trying to replace just the tube will be a complete nightmare. The coil
voltages will not match, and you'll have to match the HV, focus, and
brightness.
Older monocrome monitors generally have a driver board as part of the steel
frame, with signal inputs as described at top. Since the video signals are
being generated by the machine right there, I really doubt that the system
will be generating composite video, only to have to immediately decode it
again.

On the other hand, if there a reasonable seperation between hardware and the
monitor, and there is Coax used, then it is likely to be a composite video
signal.
