DMXKing’s eDMX1 Pro interface is an Ethernet-to-DMX adapter which can communicate via sACN or ArtNet. This tutorial shows how to configure it in TouchDesigner and in QLC+ to control regular DMX fixtures.
This has been tested on MacOS Mojave.
Power the eDMXPro via its USB connector. You can power it from a wall socket using a regular USB charging adapter, as long as the adapter can supply at least 150 milliamps. Connect the DMX connector of the unit to your DMX fixture, or to the first of your fixtures if you’ve got a chain of lights. Make sure you’ve set the starting addresses for all of your fixtures appropriately. If you’re just using one fixture, starting address 1 will be fine.
Connect the eDMX1 Pro to your computer via Ethernet. You can either connect both your computer and the eDMX1 Pro to the same router, or with many computers, you can connect them directly. For example, when you plug an eDMX1 Pro into a USB-to-Ethernet adapter on a Mac, the eDMX Pro1 assigns itself an IP address in the 169.254.x.x range, as shown in Figure 1. At that time, your computer also assigns itself an address in the same range. Open your system control panel and note the IP address of your Ethernet connection when the eDMX1 Pro is plugged in.

Note: If your eDMX1 Pro is not self-assigning you may need to use the DMXKing DMXKing eDMX1 Pro Configuration Utility to configure your eDMX1 Pro’s address. The eDMX1 Pro is factory-configured to set itself to a static IP address in the 192.168.0.x range, yet most Ethernet interfaces are configured to set themselves to an address in the 169.254.x.x range when there’s no router present. If your eDMX1 Pro is not showing up when you Node Scan, try the following with WiFi turned OFF so that the configuration utility only scans on the USB-to-Ethernet interface:

Now open TouchDesigner and add a DMX Out CHOP. In the DMX tab of the CHOP, set the interface to sACN. Then set the Universe to 1. In the Network tab, click the arrow of the Interface option menu and you should see the 169.254.x.x address that your computer self-assigned in the list. Pick that, or enter it manually. Now the DMX Out CHOP will communicate with the LeDMX Pro.

If you’re using QLC+, open the application and click the Inputs/Outputs tab. You’ll see a list of input and output interfaces, as shown in Figure 5. One of them will have the self-assigned IP address beginning with 169.254.x.x. This is the eDMX1 Pro. Choose this as your output.
Next, click the Simple Desk tab. You’ll have a row of sliders. Slide any of them to control the corresponding DMX channel coming out of your eDMX1 Pro.

This touchDesigner program will control channels 1 through 4 of a DMX universe.
