Callback connection allows to initiate a connection from the USB server side. To connect shared USB devices from your USB Server computer to the remote USB Client computer you need to create callback connection to this computer.
1) Select Remote Control > Create Callback Connection to USB Client menu item.
2) Enter remote computer's host name or IP address. Also you need to specify TCP port on which you will connect to the remote computer.
3) If connection was successful you will see the connection in the main window:
4) If connection attempt fails, it can happen in the following cases:
•Remote computer is turned off.
•Firewall on remote computer is blocking incoming connections.
•USB Redirector versions are different.
•Remote computer has refused the connection because of its IP Filters settings.
In any case you'll see the icon with an exclamation mark, which says that the connection to the remote computer is not established yet!
USB Redirector will automatically retry the connection attempts until the connection can be established.
