i just received a IR543AH from Automated Outlet. First thing I notice is that there is no AH on the model number...just IR543. But the box has IR543AH. Upon plugging it in the red light flashes 4 times and stops. None of the buttons on the top of the unit function.
When I use my remote to operate the unit here is what I get:
Press housecode -1 red blip
Press Unit Number -2 red blips
Press the On or Off -2 red blips
Then nothing happens.

I also have the IR543 which sucessfully transmits the x10 codes from my iPronto tsi6400. Can anyone tell me if the buttons on top of the IR543AH are suppose to work and if your IR543AH blips the same when using the remote.
Is there a special setting on the IR543AH I need to set?
Do I need to find a new set of x10 codes for my iPronto tsi6400
Thanks
