6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 50
Auto Video Adjustment
The left side of the target computer screen must be aligned with the left side of the Remote
Console viewport so that the tops align as well. If not, the local and remote cursors will always
have a fixed offset of that amount, even if the USB interface is used. Clicking the Auto Video
Adjustment one or more times typically cures any offset.
Screen Display Adjustments
Three features are added to the toolbar to facilitate Screen display changes:
A—Full Screen Mode (Ctrl+F10).
S—Full Screen Stretch Mode (Ctrl+F10 to return to regular mode).
R—Full Screen Mode with Changing Client Monitor Resolution (Ctrl+F10 to return to regular
mode).
Fast Sync and Intelligent Sync
The Spider device uses two different algorithms for re-synchronizing local and remote cursors.
Use the Fast Sync button on the toolbar to correct a fixed skew.
Intelligent Sync uses a different algorithm and is useful when the mouse settings have changed on
the remote system or when Fast Sync does not work. It is accessed through the Options > Mouse
Handling drop-down menu. The Sync button on the toolbar usually performs a Fast Sync, but will
perform an Intelligent Sync if the video format has recently changed.
Single and Double Mouse Modes
Continuous synchronization of local and remote cursors may not be feasible. The Spider device
provides a mode where only one cursor is visible when operating in the active Remote Console
viewport. Click the Single/Double button on the toolbar to activate Single Mouse Mode. This is
indicated by a single arrow in the Single/Double button. When in this mode, the Java KVM
console “grabs” the local cursor after clicking within the viewport and will not release it until a
“release-cursor” hot key sequence is given (Alt+F12 by default). As there is only one cursor, and
that one is confined to the active viewport, there is no issue with local to remote cursor tracking.
There also is no local cursor; Alt+F12 is required to free the cursor to move the focus from the
active viewport. Clicking when the local cursor is within the viewport will re-grab the cursor. Single
Mouse Mode may be exited by clicking on the Single/Double button.
If at some point the cursor seems to disappear, click Alt+F12 or check the Single/Double Button
as Single Mouse Mode may have been entered in error.
Note: Single Mouse Mode requires Sun Java 1.4 or higher
Local Cursor
The Spider device has an option to change the appearance of the local cursor when the focus is
on the remote computer. Select Options > Local Cursor and select one of the following cursor
options:
Default—the local cursor maintains its appearance regardless of the focus location
Transparent—the local cursor is invisible when the focus is on the remote computer. This is
similar to Single Mouse Mode except the cursor is not “grabbed” and will reappear when
moved outside of the active viewport.
