Thanks, Dave.

Aratti, with the interface PBP is designed to work with (TW 523 or equal), the transmitter is a simple physical interface to the mains. However, the reception goes thru' a processor that outputs a string PBP can recognise.

I am not familiar with the TR-2A, and could not find a schematic, but page 4 of the pdf suggests that the reception is also a simple physical interface that translates 120khz bursts to '1'; no processing is done, just the raw data received is sent to the host at TTL levels. In which case, XIN will not work. You will have to decode the bits manually, which s incidentally not too complex given all the X10 documentation on the web.
