Installation
NOTICE
Please verify that interconnect cables, interfaces, and handling of the devices comply with the
requirements (see chapter 0, page 48).
First-time users are recommended to set up the system in a test environment that is limited to a single
room. This makes it easier to identify and solve any cabling problems, and experiment with your system
more conveniently.
5.1 Setting up the System
5.1.1 Setting up the U-Switch
1. Switch off all devices.
2. Connect the USB cables to the CPUs (or CON Units when using a KVM matrix system) and to the U-
Switch.
3. Connect mouse and keyboard to the U-Switch.
4. Connect the 5 V DC power supply unit to the U-Switch.
5. Power up the system.
When powering the U-Switch, a boot process will be enabled (duration approx. 30 s).
Only after completion of the boot process, the U-Switch can be used, and keyboard and mouse will be
enabled.
5.1.2 Setting up the GPIO Interface (optional)
The GPIO interface can be hot plugged.
The GPIO interface is configured via DIP switches. In the delivery states, all DIP switches are set to the
bottom = input. The DIP switches belong to the pins listed below:
Pin 1
Pin2
Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Pin 9

To set up the GPIO add-on module for an external keypad with up to four buttons and one associated LED
each, proceed as follows:
Move the DIP switches of the pins up (ON = output) to which you want to connect LEDs.
