    Up until recently, I had been searching high and low for a good solution to working with DMX over USB. There's a lot of information, but it mostly seems to center around Artnet or a no-longer-available external (for Catalina) on It took me quite a while to figure it all out, so here's the simple solution I wish I would have found at first. I hope this pops up early in the search results! It seemed to me that DMX should be simple with the serial object, since DMX is basic serial commands. I found some information on Peter Elsea's site at which was close, but seemed a bit confusing on how it organized the data. I eventually stumbled on a git hub repo that essentially recreates the DMXUSBpro external in a serial-based abstraction: Here's the abstraction reposted here with some additional clean up and notes for posterity:
    Here's a nice patch to create a umenu of serial ports for easy selection:
    Here's a link - - to the mfg site for the USB DMX solution I bought on Amazon. It uses the same FTDI serial chip as the Enttec, so it's compatible. Thanks Thomas Ouellet Fredericks for your patch!
