Skip,
? Yup that got a lotta lotta good info in it......and? yes Spectras, A/S, MCS/MTS, and a lot more speak SB9600. To fully appreciate the coms you need to hook up your Spectra to your PC via you RIB and run a proggy called Mototools, the push some buttons etc on your Spectra and see the SB9600 coms in action. Casey prolly has that proggy handy for U/L. I'd have to search a few offline USB devices.........
I'm compiling some Q's regarding the ESP.....
