SERVICE SETUP DVI-D EXTENDER

1. Service Setup
For most applications, you shouldn't need not to make any adjustments to set up your
DVXi/LC KVM-Extender. Under some special circumstances it could be necessary to setup
configuration specials.
For some applications, you may need to open the Local Unit and/or the Remote Unit.
Unscrew the Philips-type screws at both sides at the bottom of the device. Carefully displace
the lower and upper shells of the case.
The diagnostice LED ‘Video OK’ is located at the local unit between the both DVI
connectors
The diagnostice LED ‘Video OK’ is located near to the CATx- /fiber connectors

1.1 Setup at the Local Unit
After unscrewing and opening the upper shell, please place the device in this orientation: with
the CATx/fiber connectors to the right and the electrical connectors to the left.
The main PCB then will look like this:
Use the diagram to locate jumpers.
DDC
You can select, whether the DDC is taken from internal DDC table or from local monitor or
the DDC information could be downloaded from remote monitor and stored into internal
table.
DDC JP1 JP2 JP3
From internal Table
(default)
From local Monitor
Loading the DDC Information from the
Remote Monitor into the internal DDC
Table (see also below: Loading the DDC
Information from the Remote Monitor into
the internal DDC Table)
Reset of the internal DDC Table to
Default-Values (see also below: Reset of
the internal DDC Table to Default-Values)
JP1, JP2, JP3

Loading the DDC Information from the Remote Monitor into the
internal DDC Table
To load the DDC Information from the Remote Monitor into the internal DDC Table,
please proceed the following steps:
•Switch off the Local Unit and the Remote Unit, unplug the Video-Cable to the Remote
Monitor (Dualhead devices: BOTH Monitors!)
•Open the Local Unit like described above
•Unplug Jumper JP1 and plug it to Position JP3 (Dualhead devices: jumper setting on
BOTH PCB’s!)
•Switch on the Local and Remote Unit (Please ensure, the interconnect cable – CATx or
fiber is connected - Dualhead devices: BOTH interconnect cables!)
•Wait until the LINK-LED is illuminated (see above)
•Plug the Video-Cable of the Remote Monitor into the remote unit (switch on the Monitor
before plugging if swiched off - Dualhead devices: BOTH Monitors!))
•The DDC Information of the Remote Monitors is read automatically, transfered to the
Local Unit and stored into the DDC-EPROM
•After a successful programming of the DDC EPROM, the ‚Video-OK’ LED at the
Local Unit is blinking rapidly for approx. 1 second
•Switch off the Local Unit and the Remote Unit
•Unplug Jumper JP3 and plug it to Position JP1 (Dualhead devices: jumper setting on
BOTH PCB’s!)
•Close the Local Unit like described above
•Switch on the Local Unit and the Remote Unit
•Done

Reset of the internal DDC Table to Default-Values
If you have loaded several DDC Configurations and got no satisfying result, you can
restore the original (default) DDC Table. To do this, please proceed the followin steps:
•Switch off the Local Unit
•Open the Local Unit like described above
•Unplug Jumper JP1 (all Jumpers JP1, JP2 and JP3 are now open - Dualhead devices:
jumper setting on BOTH PCB’s!)
•Switch on the Local Unit
•After a successful reprogramming of the DDC EPROM, the ‚Video-OK’ LED at the
Local Unit is blinking rapidly for approx. 1 second
•Switch off the Local Unit
•Replug Jumper JP1 (Dualhead devices: jumper setting on BOTH PCB’s!)
•Close the Local Unit like described above
•Switch on the Local Unit
•Done

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. 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.
Moment to switch JP3 behaviour
Switching during HSYNC
(default)
Higher framerate but (possibly) horizontal breaks
detectable
Switching during VSYNC
Lower framerate no horizontal breaks detectable but
(possibly) stepping pictures
