Hey,
Could you check the pin define of it?
Maybe the pin of it incorrect.You can try to swap 180^ then test it.

Do you have a multimeter?
I suggest you check the pin of the motherboard "EXT".
It should have the +5V and +12V output on the "EXT" port then use the multimeter check the adapter EXT1+EXT2: +5v and +12v pin work or not.
If the hardware is ok then you need to check the pin define on fw.

Mabye you can try to re-burn the bootloader then upload the fw.
