Nope, totally different protocol and pinout. The PropPlug is just a USB to serial converter like the USB2SER. You can use it to connect to an I/O pin of the SX chip to send/receive serial data from a PC.
You'll need either the SX-Blitz or USB SX-Key for programming the SX. It's a one time expense which you can use to program any of the SX chips.
