UltraLink 2 DVI Installation and Operation Manual 25
Click on the desired menu item with the left mouse button to add or remove it from the toolbar. A check mark
next to the menu item indicates that the equivalent button will appear in the toolbar. The Reset To Default
menu item will return all the buttons to the toolbar.
The actions performed by the toolbar buttons are described in greater detail below.
Re-Sync Mouse Button
Clicking on the Re-Sync Mouse Button will synchronize the host and connecting computer’s cursors. This is
useful if there is a drift between the two cursors, so that the gap between them can be closed. This operation
can also be performed from the Controls Menu.

When the UL2-DVI is connected to a number of computers through a KVM switch, the mouse cursor on the
host and the mouse cursor on the connecting computer may not be in the same location immediately after
switching. This is more likely if the operating systems on the two computers are not the same. Re-Sync Mouse
is often helpful in this situation. If the mouse cursors continue to drift apart, it may be necessary to perform
mouse calibration. This is described in the next section.
Auto Calibrate Button
The Auto Calibrate function is used to calibrate mouse motion for the UL2-DVI. This is usually required when
connecting to a host computer for the first time. During calibration, the unit will move the mouse and measure
mouse motion to determine the method the Operating System on the host computer uses to compute mouse
location and motion. This function is only available when the mouse is in Relative Mouse Mode.

When switching to a host where calibration is required, the Auto Calibrate button turns red and blinks indicating
a need to perform calibration. When the button is clicked, the Calibrate screen is displayed.

More information on calibrating for different Operating Systems is given in the Advanced Mouse Configuration
section of the Controls menu. Calibration generally needs to be done only at the first connection to a host
computer. Mouse calibration results are saved in UltraLink 2 DVI, and used in subsequent switching between
the host computers using the Hosts button.
Send Ctrl+Alt+Del Button
This button sends Ctrl+Alt+Del keystrokes to the host computer. By default, a typed Ctrl+Alt+Del key sequence
is handled by the connecting computer.
