2 Safety instructions
To ensure reliable and safe long-term operation of your device, please note the following guidelines:
Read this user manual carefully.
Only use the device according to this user manual. Failure to follow the instructions described can
damage the device or endanger the security of your data.
Take any required ESD precautions.
WARNING
Risk of electric shock or bruising, abrasions or severing due to an opened chassis
If the housing is opened while power is supplied to the device, electric shock may occur if the internal
wiring is touched. If a running fan is touched, bruising, abrasions or severing of fingers may occur.
There are no necessary maintenance procedures that require opening the case.
Do NOT remove the cover of the chassis.
Do NOT install the device in environments where children are likely to be present.
CAUTION
Risk of burns due to tremendously heated chassis surface after a long period of operation
When the chassis is fully equipped, the surface of the chassis can become very warm after a long period
of operation. If the chassis surface is touched after a long period of operation, this can cause skin burns.
Protective gloves must be worn to transport a fully equipped housing after a long period of operation.
Ensure that there is sufficient distance from the operator, e.g., for mounting under a table.
Do NOT install the device in environments where children are likely to be present.
Installation Location
While operating the device and the power supply units can get warm. Damage to the device can occur in a
damp environment.
Use the device only in dry, indoor environments.
Use the device only in a room with adequate ventilation.
For rack-mount installations, at least 0.5 RU (rack unit) is required above the device for ventilation.
Do not place the power supply units directly on top of the device.
Existing ventilation openings on the device must always be free.
If installing the device under the table, place the device at a sufficient distance from the operator.
Place all power sockets including the sockets for the supplied external power supply units easily
accessible and directly next to each other.
Connection
Check the device and the power supply units for visible damage before connecting it.
Only connect the device if the device and the ports are not damaged.
Only use power supply units originally supplied with the product or manufacturer-approved
replacements.
Only use power supply units without any visible damage at the chassis or the cable.
Connect all power supply units to grounded outlets.
Ensure that the ground connection is maintained from the outlet socket through to the power supply's
AC power input.
Only connect the device to KVM devices using the interconnect cable - not to other devices, particularly
not to telecommunications or network devices

Disconnect the Device from the Circuit
NOTICE
The cable plugs on the device side can contain a lock. In the event of a necessary quick and complete
disconnection from external electric circuits:
remove all corresponding cable plugs from the socket,
or set the power switch of the power outlets (if available) to the “Off” position.

4 Description
4.1 Intended Use
The U-Switch product line is designed to seamlessly control multiple sources (computer, CPU) as one
using just a single set of keyboard and mouse while the sources (computer, CPU) video outputs are
connected straight to the monitors.
Keyboard and mouse control then is being switched amongst the attached sources (computer, CPU) by
simply moving the mouse over the boarders of the displays according to their predefined arrangement.
The U-Switch is designed to be operated as a stand-alone device as well as in combination with the
complete Draco KVM extender and switch family.
To use an external switching solution via push button or dry-contact, the U-Switch can be used with the
optional GPIO module R474-BGX which offers an interface to switch the USB-HID signal and to indicate
the switching status (see chapter 9.1.4, page 43).
NOTICE
Interferences when the immunity limit values are exceeded
If the limit values listed in EN55024 are exceeded by the customers environment, reliable and fault-free
functioning of the devices cannot be guaranteed.
NOTICE
Possible radio interference in a domestic environment
This is a Class A product. In a domestic environment, this product may cause radio interference in which
case the user may be required to take adequate measures.
Follow the safety and installation instructions given in this manual.
Use connection cables according to the specifications for the length and type given in this manual.

Too low power supply
With Draco vario chassis 474-BODY6R-R1 a redundant power supply is possible up to a current of
maximum 5 A (extenders inclusive connected periphery). If the power supply of the internal power supply
unit fails, the device's power supply is secured via the 5 V external power supply unit.
If there is no redundant power supply and the current is above 5 A, the device is not supplied with
sufficient power and fails.
Note the maximum power consumption of the chassis (see from chapter 9.3, page 45).
With a current of more than 5 A, use an external power supply unit. In this case, redundancy is
inapplicable
