    DMX physical layer questions (building a DMX receiver using an FPGA)

    Thank you for your answers! Oh, you mean just convert RS-485 to TTL and feed it directly to one of the FPGAs general purpose I/O pins, instead of going the long way via RS-232! That's genius :grin:, i like that! Having a look at MAX3485 (since my FPGA inputs are 3.3V), looks pretty...
