I have this converter right now. The manufacturer provided him with a driver and software board.
I use it under the program as the boys wrote FreeStyler above. After installing you enter Setup. You will see 2 headings, one from the settings and the choice of the converter and the other from the fixture. You choose the first one and you are looking for a driver called '' Enttec Open DMX USB ''. Once accepted, the red LED on the device should flash.
You know what you connect behind the devices, you search in the program, if there are none there are 2 options. Either a familiar fixture will do for you or you can buy it on the Freestyler website. You add as many devices as you have and you can go ahead. If you have questions, write, I am happy to help.
best regards
