Chapter 2: Overview
2.5 How to Use This Guide
This guide describes the installation and configuration of the DVI-D/-I CATx/Fiber – Extender Series. Although the connection and
operation of the system is relatively straightforward, you should consider the following before getting started:

Connection and Compatibility
If you have purchased an Extender Kit, this will contain all the cables required to connect the local unit to your PC or KVM switch.

DDC information
Normally it is not necessary to make any adjustments to the DVI-D/-I CATx/Fiber- Extender. However, in some circumstances, it
may be necessary to redefine the source of DDC information for the CPU. By default, the DVI-D/-I CATx/Fiber KVM-Extender uses
its own internal DDC table. If this setting does not satisfy your requirements, the DDC table can either be switched to the locally
attached screen or could be downloaded from a remotely located screen and stored in the internal DDC table.

To modify the DDC setup, see 4.0 Service Setup.
Selecting the moment of switching to the next frame
The transmission of screen data is not synchronous to the screen change of the graphics card. Normally, the transmission is
terminated during displaying a frame on the screen. If the device switches to the new frame during the displaying period of the
old frame (somewhere on the screen), it’s possible, and that you can see horizontal screen breaks in the moment of switching
(default). On the other hand, the device must idle, until the actual frame is displayed completely (until VSYNC) -> the number of
frames per second transmitted sinks.

To modify the switching behavior, see 4.0 Service Setup.
Selection of color reduction for transfer acceleration
You can select, whether always 24-bit colors (=full color depth) are transmitted or whether the compression algorithm
automatically switches between 16- and 24-bit colors to accelerate the data transfer (default). Normally the difference between
24-bit and 16-bit is not recognizable but under some special circumstances, e.g. in photo processing installations, there might be
disturbing color aberrations. However, the automatic color switching enhances the frame count transmitted per second; fixed
24-bit color depth gives smooth color grades under all circumstances. Choose the one that’s best for your application.
