Whoops - I have one with a "parallel port" on it - I missed the USB bit - I should know better than to do emailing before coffee…
I got mine from cnc4pc.com - have a peek there to see what I was thinking about wrt the parallel port "stuff". (the C22 pendant interface, and the MPG-2 pendant is what I picked up from CNC4PC. It all went together very well, and plugs into a parallel port. the E-Stop function is tied into hardware, no software required for the EStop to work with the "parallel" port pendant - I wonder if the USB version uses "unused" pins on the usb interface for hardware E-Stop ??)
