UltraLink 2 DVI Operation
Operation of the UL2-DVI involves connecting to the unit through a Viewer and working on the host computer
from a remote location. Up to four remote users can simultaneously access and work with the host computer
as if they were in front of the host computer itself.
In order to optimize the unit’s performance, the administrator can modify its functioning in several ways. These
include modifying the Viewer Connection Options and performing operations through the Viewer window’s
toolbar. These functions are described in greater detail in the sections below.
Viewer Connection Options
With the UL2-DVI network settings configured for its network of use, connect the unit to a computer and to the
network.

As mentioned in the Installation section, there are two options to connect to the unit - using the built-in Java
VNC Viewer, and using the RealVNC Viewer downloaded from the unit or from the RealVNC website.
While both viewers are almost identical, the Java Viewer is more limited than the VNC Viewer in two ways. The
first limitation of the Java Viewer is that solo 'modifier' keys are not passed by the operating system to Java
applets. That is, when "Ctrl", "Alt" or "Shift" are pressed with no other keys, a Java applet doesn't receive those
key presses. This makes it impossible for a Java Viewer to pass those keys on to a host. The other limitation is
that Java Applets cannot access a computer’s file system. This makes the Java Viewer unable to use the
Virtual Media function. As a result of these limitations, the Java Viewer is good for quick viewing of a host
computer when it is not desirable to download a VNC Viewer to the remote computer. In all other instances,
use of the VNC Viewer is recommended.
VNC Viewer Connection Options
If the VNC Viewer has not been downloaded to the remote computer, launch it from the browser by selecting
the “Download Windows VNC Viewer from unit” option. If the VNC Viewer has been downloaded to the
computer, it can be launched clicking on the VNC Viewer icon shown below.
