Olympus foot pedals are generally not supported by InqScribe (nor any other non-Olympus transcription software).
The issue is that Olympus uses a proprietary method of communicating with their foot pedals. As yet, we have been unable to obtain the technical specifications needed to build support for the Olympus pedals into InqScribe. Olympus is just not cooperating.
As of writing, this includes: RS-23, RS-24, RS-25, and RS-26 pedals packaged with the AS-3000 and AS-4000 dictation systems.
Oddly, we have had some reports that InqScribe works with the RS-27H pedal, but we have not confirmed this ourselves. Enter at your own risk!
