I'm using 2 of these units as a stagebox combination (direct connection, no switch in between), removing complexity of a lot of cabeling. It does add latency, but as long as everything has latency it's not a big issue in my opinion. I did have to change the audio ingestion to one of the camera's. A time safer.
2110 protocol is terrible to network for, it's really for pro use only, however combining two of these units directly is really simple.
