I am not finding the X-NET device on the Botex website. Can you explain what the product is? Is it an Art-Net to DMX device? Do you have a link to the specs?
Looking at the specs, it is an artnet box. To make this work with the Hog 3, you would need a DP8000 spitting out artnet into the system. The X-Net could then take the artnet and convert it back to 5-pin DMX where needed.
