In Widget Designer 4.7, I would add a projector control node and add in the IP and Port number and click connect. It would then connect and the Output Values will show "Connected = 1".
However in Widget Designer 6, I would do the same and I cannot connect to any projector I have on the network.
These are PJLINK projectors and the usernames are "admin" and have no password.
Using port "4352".
Installed on Windows 10 Professional 64bit.
I also went in TCP Connections and added in the connection as a client and it is able to connect.
