Enable Concurrency VNC Focus | When the check box is active, every client can request the focus at any time. The focus owner does not need to give away the focus before to enable that. When a client requests the focus, a pop-up window opens for all clients. If no client objects to the request within the pre-set period of time, the focus changes after the defined time limit. Only if the Enabling VNC focus check box is enabled |
Timeout Concurrency VNC Focus | Period of time after requesting the focus during which the focus owner can object to the focus change (at most 60 seconds). This period of time is set by moving a slider. When a client requests the focus, a pop-up window opens for all clients. If no client objects to the request within the pre-set period of time, the focus changes after the defined time limit. Only if the Enabling VNC focus check box is enabled |
Select the Enabling VNC focus check box only in connection with HEIDENHAIN devices provided especially for this purpose (e.g., ITC industrial computers).

Refer to your machine manual.
