Re: [CAD_CAM_EDM_DRO] Gecko 201a

Hi Art,

Not sure what you mean by "bi-directional". The parallel port can be
bi-directional. The opto-isolators pass a "signal" in a single
direction, as I'm sure you know.

Do you mean common-ground vs. common +5VDC? The G201A's do not support
that option.

the G210 is a G201 with a "step pulse multiplier" board installed. The
Gecko's, in either case, need +5 referenced to the PC's signals. What
we would rather NOT do is get this voltage (with a regulator) from the
motor's +24 - 80v supply; NO isolation!

Hope this is clear! Gecko's library and data sheets should tell more!
