Thanks for this! I'm not having much success with the RS232 IR Blaster (from irblaster.info), though. This configuration works, but the transmission is iffy; a sent code actually affects the Pace DTA only one time in 10.

I have the blaster right over the Pace's IR receiver, and I've tried moving it around and different angles. I've tried different Transmitter settings, but only the defaults work. Nothing helps. (BTW, I'm using WinLIRC on Win XP.)

Far as I can tell, that transmitter is simply underpowered, not putting out enough IR light. Anyone else having the same problems? Or NOT having these problems with the same device?
