Re: [CAD_CAM_EDM_DRO] Pinout for Cheap DROs

James,
I ended up building a couple of these. When they are connected to my serial
port, I can issue commands and communicate with them fine. But as soon as I
connect a DRO to it, I get jibberish on the screen...

Don't suppose you've built one ot these, and gotten it to function?
