Did you ever figure out the correct wiring for your foot switch? Mine was two weeks old and my wife comes in while I'm recording and says hurry we have a problem in the laundry room. I got up with the cord wrapped around my foot, yanked the plug and ruined it. I purchased a plug from an online retailer but the plug is molded plastic so I would have to slit it with a utility knife to see if I can figure out which posts each wire is connected to. Very disappointed with Tascam, messaged their customer service asking about it and explained I bought the DP-24SD and foot switch two weeks earlier. Spent $550 on their gear and they won't even answer a simple question. Hoping that you're still a member and see this as I notice your post was made a year and a half ago.
