Yes, you can only use AES or ADAT, not both simultaneously.
You will need to use LoopSync to clock the H9000 to the PTHD card. In your first image, you can see the clock is unlocked, and this setting will not work correctly.
I would suggest using Word Clock for the clock source. The PTHD card will sync to the H9000 clock.
You may want to change “interface mode” to 32 channel if you’d like to access all 32 channels of the PTHD card.
