ok, finally got everything moved down to the basement and was trying to show off the X-10 switches with my Pronto...Signals were not working...Figured it was my codes...So I tried sending the signals through the IR543 with the top buttons and it kept locking up...Both red lights(top and side) just light up and the switches won't respond...
Any one run into this?

I also have the Maxi controller, but that works fine if I play with the switches from it.

Thanks very much in advance!
