I recently purchased a 3-switch foot pedal on Ebay. The seller said it is a Sanyo FS92 but it is not marked. I cut the end off and wired a DB9 serial connector. I could not get the diagram listed on Technical Specifications of Pedal Wiring to work.
I brought out the old RS232 breakout box to see what works. This is my diagram:
_______ Common _____ DTR Pin 4 (or RTS Pin 7 should work)
|
|__ \__ Rewind ____ DSR Pin 6
|__ \__ Forward ____ CTS Pin 8
|__ \__ Play _______ RI Pin 9
