Hello Krzysztof,
Another customer had the same issues and we provided him with the method below, which solved the issues. Will you please check if the light is turned on when sending any other numbers than 0 to CH 13?
More specifically, please select the values below in the DMX Direct Control in PERFORMANCE mode.
After selecting the values, click the red-circled button to enable DMX Direct Control.
After clicking the button, make sure that you see the button surrounded by the blue line as shown below.
Please see if any difference is made.
