Well, I built the cable/interface last night (probably too late last night..) and it seems I may have done something wrong, as I can't seem to get any data displaying through Software One. It detects the port, and it also notices when I unplug the cable from the accessory port (gives a Not Connected message) so I know at the very least it is picking up the device and the port. The display on my V1 goes blank, as it should when the concealed display is connected (or in my case, the 4k resistor loop is in place), but there doesn't appear to be any data getting to the port.
