Hi there Eva,
Like @Woland already showed us, you can use the ArtNet actors to communicate with this device.
A few things regarding Networked devices (if you decide to use ArtNet)Normally Lighting equipment is set to 10.x.x.x range or 2.x.x.x range.All devices should be set to sub-net mask 255.0.0.0 on the Network (else they can't find each other)All the devices in the network need an UNIQUE IP ADDRESS. So you can't have two devices that say 'Hey, I'm 10.0.0.1" for example.Always use an Ethernet switch or router in between your setup. (You can also do this without, but that requires an deeper understanding on Network settings)
This is what I would suggest;2x Ethernet cable1x Switch1x Net-2/31x Laptop (or Computer) with Isadora 3.x + The ArtNet send and receive actors that you can download at our Add-ons section
