Hi Boxed, I'm using a serial interface, 9 pin. I got my keyboard to work, but still no luck with the transmitter. I've reset the channels to zero, then redid them. Nothing. Question, What are the inv and exp boxes that you put checks in? Anyway, I hit calibrate, moves sticks, nothing. I have it set up for comport 1, nothing. I know that this comp is channel 1, other things work when plugged in it. I've changed the compport, still nothing. I've taken oxon/oxoff off then on, nothing. Any suggestions? perplexed, saturn
