Fixed mouse speed -

Use a direct translation of mouse movements between the local and

the remote pointer.

You may also set a fixed scaling which determines the pixel-amount of the remote

mouse pointer movement when the local mouse pointer is moved by one pixel. This

option is used to manually control the remote mouse speed and only works when the

mouse settings on the host are linear. This means mouse acceleration of OS should be

disabled, and the intelligent mouse synchronization of IP-KVM is not functioning under

this setting.

Absolute mouse scaling for MAC server

- Use this option for MAC server.

Miscellaneous Video Settings:

Noise filter

This option defines how the IP-KVM reacts to small changes in the video input

signal. Turning on the noise filter can help reduce video flickering that is often caused

by distortions, as well as lowering unnecessary bandwidth consumption. A large filter

setting needs less network traffic and leads to a faster video display, but small changes

in some display regions may not be recognized immediately. A small filter displays all

changes instantly but may lead to a constant amount of network traffic even if the

display content is not really changing (depending on the quality of the video input

signal). All in all the default setting should be suitable for most situations.

Force Composite Sync (Required for Sun Computers)

When connecting the device

directly to legacy Sun computer (with composite sync as the video output, it may be

possible that IP-KVM don’t recognize the composite sync automatically. To support

signal transmission from a Sun machine, enable this option. If not enabled the picture

of the remote console will not be visible.
