Re: TI-H: Radio/Infrared/Laser Communications
You've never built a transmitter or receiver before? There are plenty of
schematics on the web for them, but IS the TI-xx bi directional?
I thought there was only one data line, and if you hooked up a t/r to
it, then it would get an infinite loop of signals... I am not exactly
sure about the TI part...
