Basic Remote Console Operation - Lantronix SecureLinx Spider User Manual

Basic Remote Console Operation

The "focus" of the client computer is the location of where the cursor is pointed. When
the Remote Console window is open, there are three zones where the focus may be
pointed:
1. Outside the Remote Console window, interaction is with the local computer's
operating system or applications.
2. Inside the Remote Console window's viewport, interaction is with the target
computer.
3. Inside the Remote Console window but outside the viewport, interaction is with the
Remote Console control functions such as the toolbar or scroll bars.
Within the Remote Console viewport, interaction with the remote computer is generally
the same as if there were a direct connection (with a minor lag due to network latency).
Windows may be opened, applications run, settings changed, maintenance functions
performed, even system reboots performed. Powering down the target computer results
in powering down the Spider as well (unless the redundant supply is used).
Mouse/Cursor Synchronization and Operation
Typically, mouse to cursor synchronization is an issue with digital KVM interfaces. Use of
the USB mouse interface solves the problem, however many systems rely on a PS/2
interface. Spider provides several methods to fix the de-sychronization of local and
remote cursors.
Auto Video Adjustment
The left side of the target computer's screen must be aligned with the left side of the
Remote Console viewport and 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.
Fast Sync and Intelligent Sync
The Spider 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 pull-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
provides a mode where only one cursor is visible when operating in the active Remote
Console viewport. Click on 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 applet "grabs" the local cursor after clicking within the viewport and
won't 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
