This sounds like basically just an automatic switch: Perhaps something like these? http://www.bb-elec.com/product_f...milyId=102 They look a lot more complicated than what I had in mind; they look like intelligent serial port expanders for PCs - looks like some PC software is involved? I was just thinking of a simple A-B switch, where the switching occurs automatically when activity is detected on A or B... Like this: http://www.campbellsci.com/sds122 ("OTT" = "Over The Top") |
