3.4 Multicast Setup
A single multicast address is employed by NEO for the purpose of updating consoles of changes in the Relays and
Inputs.
Figure 4 - Multicast Port Number Setup
NEO sends out a single packet each time either a Relay is changed by any console or when an input changes due to external event. The Multicast Address is any address in the range of 224.0.0.0 to 239.255.255.254. A specific unicast address can also be used if only a single console is to be utilized. The Port number is a unique port to which the multicast packet will be sent. Channel Hops is the number of routers that the packet will penetrate before being stopped and allowed to propagate no further.
The Multicast Address and Port Number must match those set within the console. It is Okay to use the same Multicast Address and Port number in multiple NEO devices. The base IP address is used to differentiate the source of the I/O update. See the console documentation for more information on setting up NEO relays.
As in the case of all other web pages, the Submit button must be pressed to send the changes to the NEO under configuration.
