The UX17A Whole-House RF to IR converter works with the Firecracker Computer Interface. The FireCracker sends RF commands from your PC to the UX17A. The UX17A converts the RF commands to IR commands to control your TV, VCR, DVD player, etc. You set up the X10 Commander software to send the commands for your particular brands of TV, VCR, etc. You can then control all your Audio/Video products anywhere in your home at the click of a button from your PC.
