Hello,
So with the new 3.0 version I thought I would try to get rid of the annoying warning message on logon again.
I followed the steps in the guide: https://support.etcconnect.com/ETC/Networking/Gadget_and_Gadget_II/How_to_update_Gadget_IO_firmware_on_an_Eos_Family_console
As our console has a telephone plug I followed that part of the guide.
The firmware update was succesfull!
How ever, the console stopped outputting dmx on the regular 5 pin xlr outputs.
So I went back to version 1.3.0.9.0.5 and dmx was enabled again.
The logon message.
If anyone has a solution, thanks in advance :)
