That will depend on the IR distribution system you are using (if you have one) and the device being controlled. For the Xantech gear that I use, the exact same mono 1/8" mini-plug cables that are recommended for use with the 1070's trigger output would work for the IR input (which can be had at Radio Shack for a few dollars). If I didn't have that Xantech system, though, I could use a mono cable to connect the 1070's IR output to the input of my OPPO HM-31 switch to control the switch. I might even be able to use a Xantech emitter with the 1070's IR output, although I never tried that when I had a 950 (which had IR input/output like the 1070). That connection would not work with some devices with IR inputs, though: both the 990 and my Pace Micro and Scientific Atlanta cable boxes require an interface module to accept a signal like this.
