6.2 Download of DDC Information

By default, the factory preset DDC information is sent to the source
(computer, CPU). In some cases the factory preset DDC information may
not be appropriate, so the option exits to read the actual DDC information
from the attached monitor. The DIP switches have to be set correctly (see
Chapter 5.2, Page 24).

There are two ways to read DDC information from the attached monitor:
 Via keyboard command during operation (see Chapter 6.2.1,

Page 28).



Reconnecting the monitor cable at the CON Unit (see Chapter 6.2.2,
Page 28).

6.2.1 Download DDC via Keyboard Command

Use the following command sequence to read DDC information from the
attached monitor (except for model K473-SST).

1. Enter Command Mode (default: 2x <Left Shift>; see Chapter 5.4,

Page 26).

2.

Press the keys <2>, <Enter> to read the DDC information from the
console monitor.

The screen will blank for a short time.
The KVM Extender will exit Command Mode.
The CPU will now be able to read the actual monitor DDC information

and so allow the required video resolution to be selected.

3. Enter Command Mode (default: 2x <Left Shift>).

4. Press the keys <1>, <Enter>.

The KVM Extender will exit Command Mode.
The DDC information has been updated once. Further updates are

only possible by repeating all the steps listed above or by re-attaching
the monitor cable (see Chapter 6.2.2, Page 28).

6.2.2 Download DDC via DVI Cable

1. Move DIP switch 3 on the CON Unit to the upper position.

2. Please make sure that the monitor is on (both monitors in case of

Dual-Head devices).

3. Disconnect the monitor cable from the CON Unit and connect the

monitor cable again (In the case of Dual-Head devices, disconnect
and connect monitor cables successively).

The DDC information will be read from the console monitor,
transmitted to the CPU Unit and stored there internally.

To show successful reprogramming the LED Video OK flashes at
both CON Unit and CPU Unit for about one second.

The CPU will now be able to read the actual monitor DDC information
and so allow the required video resolution to be selected.

4. Move DIP switch 3 on the CON Unit to the down position.

Accidental download of DDC information can thus be avoided.

7.1.1 DVI-D Single Link

The video interface supports the DVI-D protocol. All signals that comply to
DVI-D Single Link norm can be transmitted. This includes e.g. monitor
resolutions such as 1920x1200@60Hz, Full HD (1080p) or 2K HD (up to
2048x1152). Data rate is limited to 165 MPixel/s.

7.1.2 USB-HID

Transmission of interlaced video signals, such as 1920x1080i, cannot be
guaranteed.

Our devices with an USB-HID interface support a maximum of two devices
compliant with the 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.
