Re: [CAD_CAM_EDM_DRO] New to group and need some info

I have no idea how i blew the optos.
When I sent them in for repair some months ago, Mariss wasnt specific as to how they were blown.So, I just assumed that it was some type of error on my part.
Not that running the +5Vdc from the power supply is a problem. I remember seeing something to the effect of using common ground as the opto source, and didnt know if I could do it with a G201 or not.
Thanks to all of you for the kind , helpful insight.

If it's working, why change it? There is a G901 rate multiplier (?)
board for the G201's that turn them into G210's. There are jumpers to
allow this "common" change. Also ask Dan M. about it. Rumors have it
that he has a solution also.

How'd you blow out the opto's? Just curious.
