Hello, I'm am looking into doing away with the wireless remote confusion in out office gym and going to something like what hospitals use, pillow speaker remotes that are wired. I am hoping not to have to Hospital grade tv's for the pillow speaker option but use the rs232 port on residential tv's. As of yet I have not found any wired control interfaces that would fit my low end spec of 5 buttons and a head phone jack. Volume control channel control and power. CC would be the 6th button if possible. Anybody with any experience wiring individual tv's to excercise machines?
