Menu Bar Toggle Hot Key:
This field can be used to select a function key for displaying or hiding the toolbar in the VNC Viewer. Click on
the arrow buttons to cycle between the available selections, being careful not to select a key that needs to be
passed to host computers or switches. For instance, if the unit is connected to a KVM switch which uses F5 to
cause some event, F5 should not be selected as the Menu Bar Toggle Hot Key. The VNC Viewer will use the
key to toggle the menu bar, and will not pass it on to the KVM switch.
Encryption – Always On, Prefer Off, Prefer On:
The Encryption field specifies whether connections between VNC Viewer and UL2-DVI must be encrypted.
Data transmission takes about 10% longer when encryption is used, but the connection is much more secure.
Clicking on the arrow buttons cycles between the three options - Always On, Prefer Off and Prefer On. As
discussed in the VNC Viewer Connection Settings topic in the Operation section, Always On causes encryption
to be used unconditionally, whereas Prefer On and Prefer Off will defer to the setting in the VNC Viewer.
Number of simultaneous VNC Users:
This setting allows the administrator to reduce the number of users allowed to simultaneously access the unit
from the default value of 4 concurrent connections.
VNC Viewer Hot Key Sequence:
This field is used to select a hot key sequence for switching between hosts, and also to display the Host
selection dropdown menu. Click the arrow buttons to select the hot key sequence used by a connected KVM
switch to trigger switching. For example, the Vista DVI Plus 4-port KVM Switch uses the Ctrl+Alt hot key
combination plus the port number to switch between to a computer. When the keys Ctrl+Alt+3 are pressed, the
VNC Viewer recognizes it as a command to be passed to the KVM switch to cause it to switch to the computer
connected at KVM port 3.
For further configuration of the unit including modifying the stored EDID table or other advanced configuration,
click the EDID Configuration or Advanced Unit Configuration buttons. These screens are described below.
EDID Configuration:
Clicking on the EDID Configuration button in the Unit Configuration Screen displays the Advanced EDID
Configuration Screen, where the EDID table stored in the UL2-DVI can be viewed and modified.
