6.1 Download of DDC Information

1. Please make sure that the monitor is on (both monitors in case of
Dual-Head devices).

2. 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.

6.2 Switchting Function (option)

If your KVM Extender has a built in switching function as an option, two
sources (computer, CPU) can be connected to the CPU unit. You can
switch at the CON unit between two sources (Computer, CPU) via
keyboard command.

1. By executing the 'Hot Key', the KVM Extender is set into command
mode.

2. If you want to switch the console to of one of both CPUs that are
available, you will have to enter the port number of the respective
CPU (1 or 2). Afterwards you have to confirm the switching with the
<Enter> key. The console is now switched to the respective CPU.

7.1.6 Serial Interface

The serial interface option supports a full-duplex transmission with a real
hardware handshake up to a Baud rate of 19,200 Baud.

The CON Unit is cabled as DTE (Data Terminal Equipment, like CPU
output) and can be connected directly to DCE devices (Data
Communication Equipment).

 A touch screen can be connected directly to the CON Unit.
 To connect to a serial printer (or any other DTE instead of DCE

device), you need a null modem cable (crossed cable) between CON
Unit and the device.

Specifications

2011-06-01 43

Operation of several devices:

The serial interface transmits 6 signals (3 for each direction). Normally,

4 of the 6 signals are handshake signals (in addition to RxD and TxD).

The following configurations, however, can be realized using special
adapter splitting cables:

 Three single 2-wire transmissions
 Two transmissions with a handshake signal
 A serial mouse and a single 2-wire transmission.

In this case, choose X-ON / X-OFF software handshake for traffic control
at printer and PC.

7.1.7 Analog Audio Interface

The Analog Audio option supports a bidirectional stereo audio

transmission, in nearly CD quality.
The audio interface is a 'line level' interface and it is designed to transmit

the signals of a sound card (or another 'line level' device) as well as to
allow the connection of active speakers to the CON Unit.

Stereo audio can be transmitted bidirectionally at the same time.

Connection of a microphone:

Connect the microphone to the 'audio' input of the CON Unit. There are
two ways to establish this connection:

 The output of the CPU Unit is connected with the microphone input of

the sound card (red). Adjust the sound card to provide an additional
amplification (20 dB).

 The output of the CPU Unit is connected to the audio input of the

sound card (blue). Choose this connection if the microphone has its
own pre-amplifier.

The CON Unit can do the pre-amplification of the microphone as well.
Open the CON Unit, locate the 'MIC' jumper on the audio board and close
the pins.
