Two number codes get confused by something

[Brian H]

I doubt it. Just extra on commands at different times.
I was interested in if two commands where timed at the same time. It sounds like is not the case.
The only thing I can think of. What is the difference between sending a command by time or by buttons.
My only thought would be the timer sends the address and then the command.
Tests this morning with  MT13A showed my theory of using the manual buttons was different.
It is not different. I was thinking of the Maxi-Controller with a separate function and address buttons.
Though it did show something. The MT13A has a defective display and half of the digits are not there.

Another thought.
The XPS2 is a 220VAC module.
So the X10 commands on each leg maybe the opposite polarity.
Since most setups would have a different level on each line.
They probably would not cancel the signal but maybe off chance get modified and look different to the XPS2.
