Another device with the IP address 192.168.1.55 could not talk to them. In the example above, the two Eos family consoles can talk to each other because they share the 10.101.
If the sound software can only output in the format "/cue/1/go", but the lighting console can only understand in the format "/lights/cue/1/fire", we have a problem.
Part of the trick in getting different devices to talk to each other is to have them speak each other's language. Other devices implement OSC in different ways for example, QLab would understand the incoming command "/cue/1/start".
For example, Eos can understand commands like "/eos/chan/1/out", which would turn off channel 1, or "/eos/cue/1/fire" to run Cue 1. OSC is an open protocol which allows the sending and receiving of human-readable messages between sound, lighting and other entertainment technology systems.
