Some networks have special security settings that block the screen either from connecting locally or communicating correctly with the server. In these cases there will be a network administrator who has implemented these restrictions and should therefore know how to lift or modify them. The following information about how our hardware communicates with our server should help lift or modify the appropriate restrictions:
Ports and Protocols
The following ports are required to be open both ways for complete communication with the CMS server:
| Port | Protocol | Function; |
| 80 (8088 can be used if port 80 is blocked) | HTTP | Download media and configuration files |
| 4701 | TCP | Log in to server and register heartbeat |
| 4700 | UDP | Remote control commands (stop, play, screenshots etc.) |
| 16732 | UDP | Local synchronization (multi-cast) |
| 16733 | UDP | Local synchronization (multi-cast) |
Static IP:
If your device needs to be given a static IP it can be assigned to the screen.
