Just an update to my previous post
The IP address the message is being sent to
In a typical Vision.Net system, Vision.Net commands trigger multiple different devices on the network simultaneously. It is therefore best practice to send UDP broadcast messages, that all “receivers” on the network can listen to.
Using unicast is fine where there is just the one Lighting Board, as you only have a single Vision.Net “receiver”.
So I prefer to specify the actual address of my LeapFrog so that the message is notpicked up by any other device on the network.
With regard to the IP Address of the sending PC ZerOS dosent actually use this so it can be any value at all eg 02 02 02 02
Finally you dont need quite as many trailing Nulls you can reduce that to 24 Nulls
