Need help using MEL command "Xout" with an X-10 PCS-05 bidir pwr-line interface

Hi Anand,

This one pdf includes 5 views of my Picoscope model 2306 screenshots (so you don't have to load the picoscope viewer software): 1st is the wide view of what looks like 4 pulse-groups, all on the screen at once [presumably 2 sets of pairs of pulse-groups, with a wider gap in between the pairs]; 2nd is a screenshot of a zoom in on the 1st of 4 sets of pulse-groups; 3rd is a zoom of the 2nd of 4 sets; 4th is the 3rd set of zoomed pulse-groups; and 5th is the 4th set of zoomed pulses in the last group.

Notice that these are all positive pulses with respect to ground. When there is no data traffic, then the PIC output to the psc05's opto-isolator is low (not pulling led current inside the opto-isolator). It seems to me that this is the way it should be, rather than inverted and pulling current without data traffic. If so, then the inverter, shown by x10pro, between the OEM equipment and the input of the psc05 really should not be there. But still, this does not activate any X-10 devices. I bought 3 psc05's, so I am about to build another identical circuit to eavesdrop on the other and compare what a real x10 remote sends to activate/deactivate house-1, module-1. Then, I can see the differences between my signal and the actual x10 remote signals, from the view of another x10 psc05's receive line.

Thanks very much,
G
