QLC+ is a feee software package for controlling DMX-512 systems. You can connect it to your system via a number of different interfaces: USB-to-DMX adapters, DMX-to-Ethernet adapters, WiFi, Ethernet, and more.
After installing QLC+ and launching the application, you will see the window shown in Figure 1. Select
Q Light Controller Plus.
Figure 1. QLC+ intro screen
QLC+ is able to act as a router, acceptings a variety of different control inputs (such as Arduino-based lighting controllers) and outputting on a number of different lighting control protocols (DMX, ArtNet, Streaming-ACN, etc.) To set up an Input or Output, first select the “Inputs / Outputs” tab on the bottom bar of the window. Figure 2 shows the QLC+ inputs and outputs panel. These are all the interfaces that the program can use to talk to our DMX devices.
Figure 2. QLC+ Inputs/outputs panel.
To create a Streaming-ACN (also known sACN or as E1.31) output from the “Inputs / Outputs” panel, first click the
Output radio button next to
E1.31. Note that there are two
E1.31 Plugins. One of them should list
127.0.0.1 (your computer’s localhost address) as the device. The other should list your computer’s IP on the local network (usually
192.168.X.XXX on a home network or
172.XX.XX.XX on an enterprise network such as NYU). Click the “Output” radio button on the second
E1.31 option (the one on your local network).
Then, double click on this connection and you will be presented with a configuration screen which looks like this:
Figure 3 shows the configuration panel for one of the I/O interfaces, spefifically your WiFi interface.

By default, sACN (
E1.31) systems assume you’re operating over a dedicated subnet with no other devices other than your controller and the DMX devices you want to control. As a result, the default network setting is to send packets to the multicast address on the subnet, which is
XX.XX.XX.255. If you’re sending sACN messages on a shared network, or worse, the internet at large, you definitely don’t want to multicast. Instead, send to a specific address. To connect to a specific output device accepting
E1.31 as an input, uncheck the
Multicast radio button and enter the IP address and port of your device.
Finally, switch over to the “Simple Desk” tab at the bottom of the screen to use QLC+’s lighting board. This will now allow you to send lighting control to the E1.31 (Streaming-ACN) output we specified in the “Inputs / Outputs” tab.
Figure 4 shows the simple light control desk.
