A simple DMX interface based on a cheap USB-RS485 converter board. Since DMX is based on the common RS-485 protocol, the simple adapter board can be used.

material:

• USB-RS485 converter board (i used this one)
• XLR female socket

connections

USB-RS485 module	DMX socket	Name
GND	1	GND
A	3	Data+ / A
P	2	Data- / B

I also added some wires to the LEDs on the USB-RS485 board to make them visible form outside the case. But this is only optional.

softwares

• DMXControl 3: https://www.dmxcontrol.de/en/
• QLC Plus: https://www.qlcplus.org/

Setup: Select as input device „Enttech Open DMX“ in your DMX-Software.
