3.1 Application

The KVM Extender is used to increase the distance between a source
(computer, CPU) and its console (keyboard, mouse, and other peripheral
devices).

The KVM Extender is designed for use with Cat X (Twisted Pair)
interconnect cables or fiber interconnect cables.

The KVM Extender with Cat X interconnect cables is unsuitable for
connection between buildings where a fiber optic based product should be
used instead.

The KVM Extender with fiber interconnect cables can also be used with
applications in environments which are difficult in electromagnetical
aspects. Electromagnetical interference can limit the maximum distance
und reliability.

6.1 Download of DDC Information

By default, data from the internal DDC list is reported to the source
(computer, CPU). If these settings do not lead to a satisfying result, the
DDC information of the console monitor can be downloaded and stored
internally. The devices have to be configured accordingly (see
Chapter 5.2, Page 18).

On all KVM Extenders with USB-HID support, the user can load the DDC
information of the console monitor via keyboard command under operating
conditions.

1. Enter Command Mode with the 'Hot Key' (see Chapter 5.2, Page 18).

2. Press the key <a> to download the DDC information of the console
monitor.

The screen goes black for a short time.
At the same time Command Mode is closed and the keyboard LEDs

return to previous status.
The video mode has been readjusted. Screen quality should be

optimal. The CPU should now show the console monitor as the
current screen, together with the available video resolutions.

The DDC information of the console monitor was loaded once.
Reloading is possible by repeating the operation.

Our devices with USB-HID interface support a maximum of two devices
with USB-HID protocol. Each USB-HID port provides a maximum current
of 100 mA.

Keyboard

Compatible with most USB keyboards. Certain keyboards with additional
functions may require custom firmware to operate. Keyboards with an
integral USB Hub (Mac keyboards e.g.) are also supported.

Mouse

Compatible with most 2-button, 3-button and scroll mice.

Other USB-HID devices

The proprietary USB emulation also supports certain other USB-HID
devices, such as specific touch screens, graphic tablets, barcode
scanners or special keyboards. Support cannot be guaranteed, however,
for every USB-HID device.

Only two USB-HID devices are supported concurrently, such as keyboard
and mouse or keyboard and touch screen. A hub is allowed, but it does
not increase the number of HID devices allowed.

To support other USB 'non-HID' devices, such as scanners, web cams or
memory devices, choose our devices with transparent USB support.

7.3.1 USB-HID Devices

The KVM Extender will support most USB-HID devices, including the vast
majority of keyboards and mice currently on the market. Many other kinds
of HID devices such as bar-code scanners and touch screens may also be
compatible

It is not possible to guarantee support for all available USB-HID devices.
In certain cases, custom firmware may be required.

USB-HID (and other) devices that are not supported as standard will
normally operate with our devices featuring transparent USB support.

Please note that concurrent operation of more than two USB-HID devices
is not possible even if you use a USB hub.
