Artnet setup on ION console

Here's my situation. I'm taking over a lighting setup on a feature film where the previous board op was using the Grand MA and artnet. We will be switching from the Grand to the ION V and using the dmx output 1 port for universe 1, Artnet setup for universe 2-3. I matched my patch on the ION from his patch on the Grand to keep all the fixtures the same without starting from scratch. What do I need to configure in the shell network area to make this happen? I have limited time in the morning to troubleshoot and want to have all the settings correct ahead of time. Thank you!
