SKU: 70304

The first choice of lighting professionals

Products don’t become an industry standard for no reason. Used on a daily basis by countless lighting designers and installers across the world, the DMX USB converter has proven for many years that it’s a reliable and robust product that excels at so many fundamental applications. It allows for USB 2.0 support through its USB-B connection to send or receive a physical DMX512 signal from PCs, Macs and Linux devices running through a vast array of third-party software that supports our DMX USB Pro software API.

This DMX USB converter features an internal frame buffer for consistently generating DMX frames when outputting, ensuring a reliable flow of data and always giving you a stable data stream, regardless of your PC’s workload.

You can also view the activity of the DMX USB Pro quickly via its LED status indicator. Use ENTTEC’s EMU software to test, update and configure your DMX USB converter alongside other products in the ENTTEC range. You can even change the firmware to support your exacting requirement (RDM or Non-RDM). It is compatible with an enormous range of commercial and free software.

So no matter what software you choose, you know you can rely on ENTTEC DMX USB PRO to do the job.

Widely compatible

Designed for simple USB connections across Windows, Mac and Linux, this device is compatible with an enormous range of commercial and free software.

Windows, Mac and Linux

Industry Standard USB 2.0 support on Windows PC and MacOS, and popular Linux flavours. Thanks to FTDI drivers, which enable the USB communication between your computer and the DMX USB Pro, it’s compatible with the majority of computers. Even Raspberry Pi is supported, for the hobbyist within you!

DMX Input or output

The DMX USB converter supports either DMX Input or DMX Output mode and comes RDM-enabled too (when running correct firmware). When outputting DMX, the Pro makes use of its internal frame buffer for steady DMX generation way ahead of the competition. No matter what project you have, this is the perfect device to accompany your computer and software to provide a cost-effective, reliable DMX connection every time.

Isolated to protect

With industry standard-5 pin input and output connections as well as 1500V full isolation for both data and power lines, you can rest assured that your computer will be protected from any stray voltage or faults that may occur on the DMX line.

Perfect timing

This DMX USB converter features an internal frame buffer for consistent DMX generation when outputting. This means it isn’t dependent on your computer’s processor to regulate a steady, reliable flow of data. Put simply, once your lighting software sends a new frame, the DMX USB Pro will grab it and keep outputting consistently until the software sends the next frame.

Change it as you please

Refresh rate is fully configurable from 1 to 40 fps. Break time is configurable from 96uS to 1.3mS, and MaB is configurable from 10.6uS to 1.3mS. You can even change the firmware to support your requirement. Two interchangeable versions of firmware (RDM and non-RDM) have been created to allow quick changing between settings using our free EMU software tool.

It’s this flexibility that makes us sure that the DMX USB Pro will simply work with your fixtures straight out of the box.
