2.7 How to Use This Guide
This guide describes the installation and configuration of the CATX DVI-D Switch. Although
the connection and operation of the system is relatively straightforward, you should consider
the following before getting started:
Connection & Compatibility
The individual CATX DVI-D Switch components consist of:
•
CATX DVI-D Switch for CATx: includes the device and power supply.
•
CATX DVI-D- KVM Local Unit: includes the device, power supply and all the cable
required to connect the CATX DVI-D- KVM/ Media Local Unit to your CPU/ Signal
source.
•
CATX DVI-D- KVM Remote Unit: includes the device and power supply
Please see also Package Contents (Page 19).
For information about connection and installation, see page 21.
DDC Information
Normally it is not necessary to make any adjustments to the CATX DVI-D- KVM/ Media
device. However, in some circumstances, it may be necessary to redefine the source of DDC
information for the CPU. By default, the CATX DVI-D- KVM/ Media 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 can be downloaded from the remotely located
screen and stored in the internal DDC table.
To modify the DDC-Setup, see Setup at the Local Unit (Page 45).
Selecting the moment of switching to the next frame
The transmission of screen data is not synchronous to the screen changes of the graphic card.
Normally, the transmission is terminated during the display of a frame on the screen (at the
remote unit). If the device switches to the new frame during the displaying period of the old
frame (somewhere on the screen), it is possible that you will see horizontal screen breaks at
the moment of switching (default). On the other hand, if the device idles until the actual
frame is displayed completely (until VSYNC) then the number of frames per second
transmitted reduces.
To modify the switching behaviour, see Setup at the Remote Unit (Page 48).
