Jomar,
Do you have any manual transmitters. You
didn't say if the modules work with them.
I don't use computer interfaces (altho I've
bought and tried several) for a number of
reasons: I found them unreliable; they
failed; and altho some macros would be nice,
I find them not worth the trouble. I do use
an XC-262 Clock Timer by X10 USA, made in
Hong Kong - it's not as old as the ultra
sound remote control I still have, but it's
old, and still works great. It's battery
backed too, fairly easy to program
(instructions permanently printed inside dust
cover), and I use the clock every day.
