1.3 Keyboard, Mouse and Video configuration
Between the IP console and the host, there are two interfaces available for transmitting
keyboard and mouse data: USB and PS/2. The correct operation of the remote mouse depends
on several settings which will be discussed in the following subsections.
1.3.1 IP Console Keyboard Settings
The IP console settings for the host's keyboard type have to be corrected in order to make the
remote keyboard work properly. Check the settings in the IP console Web front-end. See
section 3.5.2 for details.
1.3.2 Remote Mouse Settings
A common seen problem with KVM devices is the synchronization between the local and
remote mouse cursors. The IP console addresses this situation with an intelligent
synchronization algorithm. There are two mouse modes available on the IP console:
• Auto mouse speed: the automatic mouse speed mode tries to detect the speed and
acceleration settings of the host system automatically. See section 1.3.3 for a more detailed
explanation.
• Fixed mouse speed: this mode just translates the mouse movements from the Remote
Console (see Section 2.3) in a way that one pixel move will result in n-pixel moves on the
remote system. This parameter n is adjustable with the scaling. Please note that this works
only when mouse acceleration is turned off on the remote system.
1.3.3 Automatic mouse speed and mouse synchronization
The automatic mouse speed mode performs the speed detection during mouse synchronization.
Whenever the local and remote mouse cursors move synchronously or not, there are two ways
for re-synchronizing local and remote mouse cursors:
• Fast Sync: the fast synchronization is used to correct a temporary, but fixed skew. Choose
the option using the Remote Console options menu (see section 2.4.1) or press the mouse
synchronization hotkey sequence in case you defined one.
• Intelligent Sync: If the fast sync does not work or the mouse settings have been changed
on the host system, use the intelligent resynchronization. This method takes more time than
the fast one and can be accessed with the appropriate item in the Remote Console option
menu (see section 2.4.1). The intelligent synchronization requires a correctly adjusted
picture. Use the auto adjustment function to setup the picture, and make sure that there are
no windows at the top left corner of the remote desktop that are able to change the mouse
cursor shape from the normal state. The Sync mouse button on top of the Remote Console
can behave differently, depending on the current state of mouse synchronization. Usually
pressing this button leads to a fast sync, except in situations where the KVM port or the
video mode changed recently.
Note: At first start, if the local mouse pointer is not synchronized with the remote mouse pointer,
press the Auto Adjust button once.
