[dad68]

The firmware of my interface is : 1.19

Suddenly the interface no longer works.
The LEDs flash one after the other.
Can not use sunlite. (same in stand alone, The LEDs flash slowly one after the other )
I used the application tool, then it working.
I do not know why

Now i can use the inteface ? what happened ?
Do you think i have a problem with the interface

( yesterday I changed the timing dmx)

Hi, download the latest version of the software you use and write the firmware included with this. Also try to re-write the default DMX timings.
