DVI-D FIBER KVM-EXTENDER

2.6 How to Use This Guide

This guide describes the installation and configuration of the DVI-D Fiber – Extender Series. Although the connection and operation of the system is relatively straightforward, you should consider the following before getting started:

Connection & 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. Please see also: Package Contents (page 15)

For information about connection and installation, see Interconnection Cable Requirements, page 17.

DDC Information

Normally it is not necessary to make any adjustments to the DVI-D Fiber KVM-Extender. However, in some circumstances, it may be necessary to redefine the source of DDC Information for the CPU. By default, the DVI-D 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 remotely located screen and stored in the internal DDC table.

To modify the DDC-Setup, see Service Setup (page 31).

Selecting the moment of switching to the next frame

The transmission of screen data in not synchronous to the screen change of the graphic 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, 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 behaviour, see Service Setup (page 31).

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. However, the automatic color switching enhances the count of frames, transmitted per second, fixed 24 Bit color depth gives smooth color grades under all circumstances. Please select to you choice the better mode.

To modify the color depth, see Service Setup (page 31).

Compatibility

Devices with PS2 connectors are NOT compatible to devices with USB connectors.
