I assume that the F/T motherboard is the same. Basically, when you change the interface board to serial, 2K serial, or IEEE (or anything else) you put this jumper wire onto a large pin on the interface. I assume, however, that you could rig up a switch...but I've never tried it...so don't blame me for that little puddle of beige plastic... Hope this helps, Jonathan
