DX5401 ATEN/ATSE

Hi all!

I'm trying to make some changes to the bootloader of the DX5401-B0, but I cannot set the debug flag to 1.
When I type ATSE DX5401_B0, it gives me this code: 2501000E090013009C030490330691452269
Which code can I use to run ATEN 1 command and enable debug mode?

Thank you for your help!
