The SWM (pronounced SWiM) Single Wire Multiswitch allows one to run a single cable which is shared via a splitter by up to 8 receivers. The SWM modulates the selected bands from the LNBs onto 8 channels, one for each receiver. The band/pol selection from each receiver is put onto it's particular channel allowing up to 8 decoders to split off the same coaxial cable. Multiple SWMs can be cascaded for more receivers, but normaly there is one coax run for each 8 receivers.
The SWM compatible DirecTV decoders signal the multisitch using DiSecq, 13V, 18V and 22KHz tone to tell the SWM which satellite and which pol and it wants to watch. The SWM then modulates the required satellite and pol onto the coax on that receivers carrier that has been assigned by the SWM module.
