ENTTEC DMX USB PRO Reviews

Used with CHINLY wireless

By Edgardo

You'll need a Male 5pin DMX to Female 3pin DMX adapter to work with a Chinly Wireless DMX transmitter. I also bought a USB B to USB C Printer Cable to connect directly to my Macbook Air. Works flawlessly with Show Buddy Active.

The ENTTEC are my Go to.

The ENTTEC DMX Pro are my go-to for a DMX device. B&H is my go-to source for all things Synology, and UniFi and anything else that is in their inventory that I need. I love it when B&H carries products that I am purchasing due to Price, Customer Service and Shipping. All around a GREAT Company.

I purchased this and used a Kopul DMX53PA-S 5-Pin Male to 3-Pin Female DMX Adapter Cable (6") BH #KODMX53PAS to go out to my 3 pin DMX lights and it worked fine.
