Hello Fausto,
We did test DT9804 on Windows 10 with DT Open Layers (OEM) v. 7.8.9 software without any success. Computer recognizes the DT9804 board, but gives no signal at all. I should mention, that we have DT9834 board that we tested in the same settings as DT9804, and works fine every time on all computers. Are we running out of options at this point?
The question now - is DT9804 repairable? And is it worth to repair it?
Thank you, Olga
