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

I looked at my old Balls monitor in the shed. Yes, the connections match
Keith's pinouts. I have two of them, but I am in south Africa.

I do have the circuit diagram somwhere if you need it. But i'll have to do
some searching, so let me know.

Regards
Roland
