Mouse Synchronization At Console Side - QUANTA QSSC-980 User Manual

Keyboard and Mouse redirection
Once the Remote KVM function is launched, Java RSM emulates USB 2.0 keyboard and mouse devices. As a re-
sult, the managed server's BIOS or OS will detect the USB keyboard and mouse attached, and loads their drivers
to service them.
Keyboard and mouse redirection architecture is described in the following illustration.
The Java RSM captures keyboard input and mouse movement/click events and sends them to BMC. The KVM
service receives and packs them in USB HID format then transmits the packet to the managed server through the
USB interface and protocol.

Mouse Synchronization at Console Side

When the Remote KVM application is launched on the console PC, the mouse position of the remote server and
the console are automatically synchronized to the top-left of the screen. However, once the managed server mouse
is moved locally, the console PC mouse position is different from the redirected managed server mouse.
In order to re-synchronize the mouse, click the Mouse Synchronization button on the toolbar.
Note:
If the mouse is asynchronous after clicking mouse synchronization, ensure that
mouse acceleration is turned off.
To turn off the mouse acceleration function:
•
In Solaris or Linux at the command prompt:
xset m 1 1
•
In Windows XP and Windows 2003:
Click Control Panel
•
In Windows 2000:

Mouse Control Mode Selection
Two types of USB mouse cursor axis movement are supported: Relative mode and Absolute mode.
Relative mode—a common USB mouse type, mouse axis movement is measured according to x and y coordi-
nates and then compared to the last axis position to calculate the current mouse position. If the resolution of the
physical mouse device is low, causing the mouse cursor to move slowly, the operating system provides the mouse
