Hi,
  I know there was some discussion recently about a RS232 to DMX
converter. I did find some good info on how to transmit DMX data, but I
need to build a device that could read DMX data and perform a task based
on the channel and 8-bit data value it receives.
  I'm guessing that the PIC chip would have to constantly analyze the DMX
bus, but I need some more info on whether I have to use a RS488
transceiver as is done with a transmitter. Does anyone have more info on
this or links to web sites?
  Thanks,
  Dennis
