OK, Help!
I have a Pronto TSU 2000 which I have had for a long time and love.
I recently got an IR543AH. I'm having trouble controlling x10 stuff from the pronto.
I downloaded the ir543ah-x10.zip from the files section and tried to use it.
It only seems to turn something on and off if it's the last thing I turned on by some other means (what the heck does that mean).
If I use some other x10 remote to turn "C1 on", now the pronto codes will turn that device on and off no matter if I press different unit code.

I think it's probably some "sequence" of buttons.
On the above ccf, I would press the "C" code, then the "6" unit, then the "On" code.
One would hope that would turn C6 on, but it turns whatever the last unit in the house used to "on"
How / what would I transmit to for example send "C6 On"
Thanks a lot
