dS3484 how to activate it with ETH8020?

[bayensf]

Hello, I bought a dS3484 board and want to set it up to create a wired alarm system. My current wired Bosch alarm is old and I want to integrate my existing PIRs in Domotics and Dashticz. I found the ETH8020 hardware device, when selecting it I see the error "Error: ETH8020: Error connecting to: http://192.168.0.**". I tried a lot of settings in the setup of the board, no success. It works with the android telephone app and I see it in the internet browser. I am not a genius with programming, but I know how to edit web pages and have good knowledge about electronics.
Anyone out there whom can help me me? I am Dutch, so if it helps PM me in Dutch. I will keep everybody informed about my journey with this project. Promissed!
