4. DDC Information Download
By default, data from the internal DDC list is reported
to the source (computer, CPU). If these settings do not
work properly, you can download and store the
console monitor’s DDC information internally. The
devices must be configured accordingly.
On all KVM Extenders with USB-HID support, users
can load the console monitor’s DDC information by
using keyboard commands.
1. Enter Command Mode with the “hotkey.”
2. Press the <a> key to download the console
monitor’s DDC information.
The screen will go black for a short time.
Command Mode is now closed, and the keyboard
LEDs return to previous status.
This re-adjusts the video mode and should give you
optimal screen quality. 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.
To re-load the DDC information, repeat the operation.
During DDC transfer, the status LEDs on both CON
and CPU units flash while reading (CON module) and
copying (CPU module) information.

2. System Setup
NOTE: I f you are a first-time user, we recommend that
you set up the system with the CPU Module
and the CON Module in the same room as a
test setup. This will enable you to identify and
solve any cabling problems, and experiment
with your system more conveniently.
NOTE: Verify that interconnect cables, interfaces, and
handling of the devices comply with the
requirements (see the user’s manual).
2.1 Basic Module Setup
1. Switch off all devices.
CON Module Installation
2. Connect your monitor(s), keyboard, and mouse to
the CON Module.
3. Connect the CON Module with the interconnect
cable(s).
4. Connect the 5-VDC power supply to the CON
Module.
CPU Module Installation
5. Connect the source (computer, CPU) with the
supplied cables to the CPU Module. Make sure the
cables are not strained.
6. Connect the CPU Module to the interconnect
cable(s).
7. Connect the 5-VDC power supply to the CPU
Module.
8. Power up the system.
NOTE: To power up the system, the following
sequence is recommended: Monitor – CON Module –
CPU Module – source.
NOTE: The basic module with VGA/DVI-I input is
connected as mentioned above. For a complete
and detailed description of the setup and
configuration of the VGA option, see the
Media/DVI Converter (ACS411A-R2) manual.
2.2 Setup of Upgrade Modules
You can hot-plug the modules.
Upgrade Module Analog Audio/Serial:
1. Connect the audio source with the CPU Module (for
example, CPU audio output with audio input, CPU
audio input with audio output).
2. Connect the audio output at the CON Module with
headphones or suitable speakers.
3. Connect the audio input at the CON Module with a
suitable microphone.
Upgrade Module Digital Audio:
1. Connect the digital audio source with the suitable
audio input of the CPU module.
2. Connect the audio output of the CON Module with
suitable speakers or audio amplifiers.
NOTE: If several active sources are connected, Mini-
XLR input takes priority. The audio signal is
available at all outputs.
Upgrade Module USB-HID:
1. Connect the CPU with the CPU Module (USB-HID 2).
2. Connect the USB-HID devices with the CON Module
(Connect to USB-HID device 2).
