  • DMX input to the BRX

    Please confirm that I need the BX-SERIO module to send or receive DMX.

    Can I use the RS485 POM or the built-in serial port? They don't appear to be available options in Do-More Designer, V.2.5.2



    Thanks,

    Ryan Poethke

    Yes, you need the BX-SERIO module for DMX512 (master or slave). Also, make sure your BRX PLC is at least Do-more Technology Version 2.5 or later. FYI, the latest version of Designer and DmT is 2.6.2, but 2.5 should work.
    There are 10 kinds of people in this world, those who know binary, and those who do not.

      We considered it, but DMX512 requires more precise timing than was practical from the PLC's onboard port. In the SERIO we have absolute control of the timing.
