With Express Scribe Foot Pedal Control Setup Wizard running, I played around with a short jumper wire and shorted pin 4 with each of the other pins (on the back of the computer) until Express Scribe would play. I then wired into that pin.
Yes, there appears to be a bug in the setup wizard. If you only have two buttons, it makes your "play" button a "fastforward" button, no matter what you do. You have to configure the pedal as three-button, with a dummy fastforward, in order to get a functional play and rewind.
For those of us converting two-button pedals, there are a few ways to go:
1: Leave two bare wires hanging out of the connector, and manually short them when the setup wizard asks for the fastforward pedal. Then use the regular pedals for play and rewind. This is Alex580's technique, more or less.
2: Drill and mount a third button into the pedal, even if it's somewhat awkwardly placed, it'll be fastforward and seldom used (really, only used during the setup wizard) so it won't matter.
3: Manually edit the registry. You're looking for HKCU\Software\NCH Swift Sound\Scribe\Settings\
The registry key names are pretty self-explanatory. Change the values of "pedalsleft", "pedalsmid", and "pedalsright" according to the following:
pin value signal function
1 8 DCD play
4 n/a DTR common
6 2 DSR rewind
8 1 CTS fastforward
9 4 RING optional
So to make my two-button pedal work, I've got pedalsleft=2, pedalsmid=1, pedalsright=8. Don't use pin 9 (ring indicator) if you can help it, as some computers reassign it. (I've got a Toughbook here that puts +5v on pin 9 for powering external peripherals, for example. And I've used serial GPS units that expect power on pin 9, so in general, stay away from it.)
Incidentally, the number of pedals you select in the pulldown menu doesn't change anything except the number of prompts you get when you run the setup wizard.
