Master Ip Local Port Send_Commands; Udpsendto - AMX NX-1200 Webconsole And Programming Manual

Master IP Local Port SEND_COMMANDs

These commands are specific to the Master and not the Controller. These commands are sent to the DPS 0:1:0 (the Master). A
device must first be defined in the NetLinx programming language with values for the Device: Port: System.
In these programming examples, <DEV> = Device. The term <D:P:S> = Device:Port:System.
