CHAPTER 3: RARITAN REMOTE CLIENT 25
Connection and Video Properties
UST-IP's dynamic video compression algorithms maintain KVM console usability under varying
bandwidth constraints. Unlike competitive solutions, UST-IP optimizes its KVM output for not only LAN
utilization, but also via the WAN and dial-up. By dynamically adjusting color depth and limiting video
output, UST-IP offers the optimal balance between video quality and system responsiveness in any
bandwidth constraint.
Power users of RRC should understand the following adjustable parameters in the Connection Properties
and Video Settings dialog boxes, and familiarize themselves with the effects of each setting – in different
operating environments; they can be optimized to your requirements.

Opens Modify Connection Properties dialog box to manually

Color Depth, etc.).
To access the Connection Properties dialog box, either select Connection → Connection Properties from
the RRC Menu Bar, or click the Connection Properties shortcut button in the RRC Toolbar.
Connection Speed
The Connection Speed selection box allows users to manually constrain UST-IP from using more than a
designated amount of network bandwidth. While UST-IP normally automatically detects available
bandwidth, users can use the Connection Speed setting to manually inform UST-IP of a bandwidth
constraint – whereby UST-IP adapts its behavior and simply refrains from even attempting to consume
more than the available bandwidth.
Color Depth
For most administrative tasks (server monitoring, reconfiguring, etc.), server administrators do not require
the full 24-bit or 32-bit color spectrum made available by most modern video graphics cards. Attempting
to transmit such high color depths, then, would waste an enormous amount of precious network bandwidth.
Instead, UST-IP can dynamically adapt the color depth transmitted to remote users, in order to maximize
usability in all bandwidth constraints.
• Progressive Update option: The extremely innovative UST-IP feature of Progressive Update can
enormously increase usability in constrained bandwidth environments. When Progressive Update is
enabled, UST-IP first sends an image of the remote desktop at lower color depths, and then provides
higher color depth images as bandwidth allows.
This option is very similar in philosophy as the common World Wide Web notion of "interlaced
GIF" files.
Note: When Color Depth is set to Auto Select Color (default), Progressive Update is automated. UST-IP
will enable/disable Progressive Update as needed, disabling it for fast connections and enabling it for slow
connections.
