The DMX protocol is exactly the same as the RS485 protocol, so we can use any RS485 USB converter to control DMX devices. DMX controllers are usually not that cheap, using this guide, you save money for possibly a hardware midi controller for your lighting software.

– Soldering Ion + Tin
– A spare Network cable.
– USB RS485 network interface :
!!You need an RS485 adapter, an ethernet adapter will NEVER work!!
-Other confirmed working adapters:
*UNITEK Y-1081 USB 2.0 to RS485 RS-485 DB9 Serial Adapter Converter
– Female XLR Plug:
*Any Female XLR will work. Dealextreme has cheap / Decent quality plugs.
Take your network cable and cut one RJ45 connector off:
Then strip the end of your open wire :
Now cut off all wires EXCEPT Orange, Orange-White, and Brown-White :
Now take apart your XLR Plug :
Take your cable and slide the last 2 parts over your cable, This cannot be done once your cable is soldered!
This will be the 3 wires we will be soldering to our XLR plug :
1: GND => Brown-White
2: Data- => Orange
3: Data+ => Orange-White
Solder the connections, screw your plug together, Your cable is now done.
USB Ethernet adapter Pinout :
Now in settings choose the interface “Enttec open DMX”.. this device is based on an RS485 and works with any RS485 device.
Now click save, add your fixtures and start programming your show.
Are you sure you used a “Straight” network cable?
? – What is the maximum length?
I’m not sure but network cable has a maximum length of 100meters, i only tried 15meters and had no problems.
The FTPI chip should work without manual driver installation, if for some reason you want to install drivers manually or you are using Windows XP or older, download these drivers :
