Low Bandwidth KVM Settings

Following are the settings that Raritan recommends in order to achieve
optimum performance when using KVM over low bandwidth speeds
typical of DSL connections. This information applies to both virtual KVM
and MPC.

Setting

To achieve optimum performance:

Connection speed

Select Connections > Properties.

Set the Connection Speed to a value that
best matches the client-to-server connection.
This ranges from 384 Kb (for lower DSL
speeds) to >1MB.

Color depth

Select Connections > Properties.

Reduce the Color Depth as far as possible.
The lower this is set, the better the video
refresh response on the target will be.

The impact is noticeable when opening and
moving folders on the target desktop.
Specifically, the display is updated much
quicker, improving the overall usability of the
connection.

Noise filter

Select Video > Video Settings.

The Noise Filter should be set to 7 (the
highest value). At this setting, less bandwidth
will be used for target screen changes,
resulting in improved local and remote
mouse synchronization.

Note: Setting the color depth to low and the noise filter to high will
cause a degradation in how the video is displayed. However, this
tradeoff is offset by the overall improved usability due to better mouse
synchronization and video update.

Smoothing

Select Connections > Properties.

Set Smoothing to high. This will improve the
appearance of target video by reducing the
video noise that is displayed.

Auto color calibration

Select Video > Auto-sense Video Settings

Deselect the Automatic Color Calibration
checkbox to disable the option.

Quick sense video
mode

Select Video > Video Settings to open the
Settings dialog.

Select the "Quick sense video mode" radio to
