Hi @Gehringer,

Many thanks for the info. In particular I was looking for the pin assignments on the 'Front Panel Header F_PANEL (black)' similar to:

Hi @Gehringer ,

The motherboard is manufactured by ECS in China. I obtained information about the pin assignments from their website for the 

B450AM4-M motherboard which is similar in appearance to the B550A4-EM in the Akoya. I connected as in the diagram I posted and it all seems to work.
