Does anyone have any experience/comments on attaching 2 optical devices to 1 input on an optipac?
I'd like to hook up two single axis inputs to just one input (eg X axis P1 rotary) on the optipac. The controls would never be used simultaneously, but I was wondering if there would be a grounding issue. Would I connect the grounds on each device to the ground on the optipac?
Or should I just make a USB mouse hack for the extra device - I have other usb devices and am worried about devices swithing id's on rebooting.
any comments welcome.
