The Client Config dialog looks like the image below:
☑ Connect To Single Server - If you enable this option you will be allowed to configure only one client and only the first IP Address row will be active. All four players will then send their outputs to this address.
In the IP Address field enter the address of the desired output server. From the Output drop-down list select the output from which player to be used, where Output 1 corresponds to Player 1 and so on.
NOTE: You can use the same output more than once and connect it to different servers.
Use the Port Is Preview option if you would like to connect one of the Players to one of your preview screens. This is done via the MultiPlayer option.
In the Media Extensions field you can list the desired file formats, which you would like to be displayed in the File Media Browser.
