Hi All,
··· I have 2 BS2's communicating on PIN 8. What I would like to do is put a LED on the line to see when traffic is being sent. Is this possible and if so can you tell me the connections I need to make?

Thanks,
·· Ken

    I think it should just be as simple as hooking up a resistor (470-Ohm or more would be fine) and the LED (in line of course) to ground.
    I've done this, and it is shown that way for pulsout in one of the Parallax books I read, so serial should be the same.
    If you want to put less load on the serial line, you could run it through a transistor.

    I will give that a try. Thanks
