I am looking for technical information that I can use to educate myself and my employees regarding the theory of operation behind multiswitches, and specifically, what is electronically different between a cascadable and non-cascadable ones. We fried a cascadable multiswitch by connecting a non-cascadable one to it, and I just want to understand why that presented the cascadable multiswitch with a "short".

Thanks,

Cascadable models emit a 22Khz tone on the Sat-B inputs. Everything else is the same.

It sounds like there was a problem with one of the switches. If you are going to connect a pair of switches you should probably do it in parallel with some high frequency, DC-blocked (on one leg) splitters.
