Nice guy that I am I made a quick drawing for connecting it all up. So that’s where I come in.įortunately the wiring is pretty basic and the pins are clearly marked on the back side of the circuit boards. You’d be hard pressed to find much useful on line as well. One of the gotchas of this device though is it comes with ABSOLUTELY NO DOCUMENTATION WHATSOEVER. It performs extremely well in a home environment and has great specs. A decent transmitter receiver kit will set you back a whopping $10 or so.
