Yes. Depending on which Gecko you have they have a terminal marked common. Contrary to logic this was often a common 5V rather than common as in common ground. That's why you have to read the manual carefully.
Also check in on the Yahoo Gecko group or
http://groups.yahoo.com/group/DIY-CNC/
or
http://groups.yahoo.com/group/CAD_CAM_EDM_DRO/
Someone there can assist you with how to wire a Gecko.
Since the Gecko's were designed to be driven directly from a PC parallel port, I think the ports pull the Gecko inputs to ground sinking current through the opto isolator. But don't quote me on that. The manual or the Gecko support can better answer those questions
