Hi,
Is there such thing as a powerline FSK comms system where multiple points along a long cable (bus) are
supplied power by the cable, but also the cable is literally shorted/opened at a certain frequency so as to give an
FSK powerline comms system? All the load circuitry doesn't get affected by the bus getting shorted because the loads
are supplied by capacitor banks which are downstream of high resistances connected to the bus so that the capacitor bank is
effectively "isolated" from the bus.
Obviously there just needs to be some initiation time so that the capacitors can get charged up at power up time.
