Transmitting DDC information

It is only possible to output the video signal on the monitors that are connected to 

the 

DVISplitter2

 video extender if the video signal 

and

 the DDC information are 

transmitted.

Transmitting DDC information transparently

Saving and providing DDC information

If the DDC information is not transmitted over the whole distance, due to a low 

DDC graphics card interface, for example, no image appears on the monitor or the 

desired resolution possibly cannot be adjusted correctly.

In this case, the monitor’s DDC information can be saved in the 

DVISplitter2

 video 

extender and be provided to the computer. For this, proceed as follows:

In the default setting of the 

DVISplitter2 

video extender

, 

the

DIP swit-

ches are arranged in the pictured settings (1-OFF, 2-OFF, 3-OFF, 

4-OFF).

In this mode, the DDC information of the monitor connected to the 

DVI Out 1

 interface is transmitted to the 

DVI CPU

 interface.

1. Remove all cables and the power pack connected to the 

DVISplitter2 

video

extender.

2. Change the DIP switch’s positions on the device’s back panel

according to the figure on the right.

Switch setting: 1-OFF, 2-ON, 3-ON, 4-ON

3. Connect the power pack to the 

12VDC

 interface.

The fast blinking of the 

Clock

-LED signals that the DDC learning mode has

been activated.

4. Connect the monitor whose DDC information you want to save in the

DVISplitter2

 video extender to the 

DVI Out 1

 interface.

After the monitor’s DDC information have been successfully read out, the yel-

low 

Clock

-LED is blinking slower.

5. Remove the power pack and change the DIP switch’s setting to

provide the saved DDC information at the 

DVI CPU 

interface.

Switch setting: 1-ON, 2-OFF, 3-ON, 4-ON

6. Proceed as described in the chapter 

Installation

 on page 3 to connect all devices

to the 

DVISplitter2 

video extender.
