Use two of these to control a projector from a global cache device so i can turn things on by voice. I was concerned with the longer run (40 ish ft) but works exactly as expected.

*by W***X on Reviewed in the United States on 22 July 2017*

Use the same brand to match the other end. I had to use a bull modem adapter because I was to lazy to look at the wiring diagram and adjust my terminations.
