For a Crestron module to work with CueServer, the module must issue commands to the CueServer over one of the following:
Commands issued to cueserver via RS-232, Telnet or UDP should be CueScript, which you can learn more about in the CueServer Manual.
Commands via UDP must be unicast to the CueServer's IP address or multicast to the group address 220.127.116.11 over port 52737.
Commands through HTTP should be issued in accordance with the CueServer CGI API, which you can find more information about here.
Commands may be initiated from CueServer using the CueScript command WRITE. To learn about the Write command, click here.
