I've got hold of a secondhand Sanyo FS-53 two button foot pedal and woudl like to try and convert it to make it useable on my PC. The thing is it has a 6-pin DIN connecter (not a 6-pin mini-DIN or PS/2) and not a nine pin serial connecter, The wiring instructions given on the NCH website don't seem to include this type of conversion. So, what I'm interested in knowing is has anyone tried to convert a pedal like this, do you have have any instructions and what type of connection can it be converted to?
