As it was already late here are some additional informations:

For years i'm using PBP but never used Xin xOut.

I have the following questions/problems

I just want to switch on and off a module with adres B 2
the zerocros pin looks ok with a scoop, I see TXdata, and when receiving from another X-10 transimitter
I see RX data, so I may assume that the X-10 to TTL converter is working properly except for Logic inversion see Question 3)

1) Is there any difference in timing or parameters (define) for 60hz or 50Hz operation ? (Europe 50Hz)
2) I found in the latest on-line documentation a define: DEFINE XOUTXLAT_ OFF 1 but dont find any additional explication
3) I use the XM-10 TTL interface optocoupled (european version of the 2 way TW-523) what about logic inversion ?
they suggest to invert the TXdata as showed here: http://www.marmitek.com/en/pdf/8942.pdf
4) are there any other code examples ? and any X-10 European users ?
