3 Output RS-232 DMX Engine With DMX Input Monitoring
Here’s another in our series of ‘There’s Only One of These in the Whole World’ designs.
A client needed a modification to our very popular RS-232 DMX Engine. They were using a PLC to drive a series of very remote DMX light fixtures. This is a very common use case, and many of our customers who work in industrial control have done similar things.
However, this group needed three separate data outputs instead of one. And further, their PLC needed to monitor several channels of a DMX stream which was generated by other equipment. They asked if we could help.
Of course!
It took an afternoon to edit our regular circuit board design to include the new features. Our across-town vendor can fabricate short runs of circuit boards in five business days*, so the files were emailed to them. Once the boards came back, they were loaded with components, programmed and tested. Per the customer’s request, we added a command to the firmware which allows the state of any or all of the incoming DMX channels to be queried at any time.
It took most of an afternoon to generate and fabricate the chassis design, including a few test cuts in thin card stock.

If you need something similar, or if you’ve searched the entire Internet and can’t find the precise thing you’re looking for, let us know. There’s a good chance we can help.
* They can move quickly, too. It’s stop-your-heart expensive, but we’ve done four hour turn times with these guys before. Pretty neat.
