The H9000 uses TASCAM standard for all of its pinouts – https://tascam.com/content/downloads/products/220/DB-25_Pinout.pdf
When connecting the H9000 to another device via the AES-EBU connector, you must use the correct AES-EBU DB-25 cable. If the other piece of equipment uses Yamaha Standard pinout, you must use an AES-EBU TASCAM to Yamaha crossover cable.
