Standard Thin Client Ex connection
Standard Thin Client Ex connection
The standard application of the Thin Client Ex system is a direct Ethernet connection via the
KVM box to the host PC.
To enable you to establish this connection quickly and correctly, the following section deals with
the necessary connections.

2.1
For further information, please also refer to Section 3.2 Standard application Thin Client
Ex system.
Thin Client Ex connection to the KVM box
The Thin Client Ex station is connected to the KVM box via an Ethernet connection which can
consist of copper (Tx) or optical fiber (Fx).
2.1.1
Ethernet Tx connection
Cable and connector assignment:

If the wiring version shown here (cross-link connection) should prove to be problematic,
you can use a one-to-one pin assignment.

Ethernet Fx connection
Host PC connection to the KVM box
Several connections are required from host PC to the KVM box so that the Thin Client Ex
station can display the screen contents of the host PC and operate it, too. In addition to the
voltage supply of the KVM box, these include the signal lines for video, mouse and keyboard
signals. All these connections are located at the black connector sockets.
2.2.1
Standard connection via DVI and USB

2.2.2
Standard Thin Client Ex connection
Connection via DVI and PS/2
As an alternative, if the host PC has no USB support for pointer devices and keyboard, the PS/2
connection of the KVM box can be used for the connection of these.
2.2.3
Connection via VGA
If the host computer has no DVI video signal, the KVM box can also be connected via a VGA
video signal and cable. In this case, however, each host PC resolution used requires a video
calibration of the KVM box.
A VGA-DVI-I adapter is also required, since the KVM box only has a DVI-I connector. The KVM
box's scope of delivery includes such a VGA-DVI-I cable for this purpose.

2.3
Standard Thin Client Ex connection
Connection of local operating unit to KVM box
If the option of locally operating the host PC is also required, it is possible to connect the
mouse, keyboard and monitor to the KVM box for such a local operation. For this, the KVMA
connection field called "Lokal" (named MOUSE/KEYBOARD/MONITOR/SPEAKER on the KVM
box itself) is used.

For further information on the connections to the KVM box, please also refer to Sections
6.6 Connection Options and 6.6.5 KVMA connection field "Lokal".

Mouse and keyboard connections to the "Lokal" KVMA connection field have to be the
same as the mouse and keyboard connections from the KVM box to the host PC.
If the host PC is connected to the KVM box via the USB connection, keyboard and mouse
connections at the "Lokal" KVMA connection field also have to be via USB. If the host PC
is connected to the KVM box via PS/2, however, keyboard and mouse connections at the
"Lokal" KVMA connection field have to be via PS/2.

Instead of the DVI connection the analog VGA version can be used to connect the screen.
The type of connection from the local monitor (DVI or VGA) is independent from the type
of video connection between the KVM box and the host PC.
For this, please note that the KVM box only has a DVI-I interface, so that a VGA-DVI-I
adapter or the VGA-DVI-I cable must be used for the VGA option.

System Function and Description
System Function and Description
The Thin Client Ex devices are remote stations used for operation and visualization, where the
PC that is operated is located in the safe area.
The versatility of the Thin Client Ex system means that it can be adapted to suit a large variety
of applications. Regardless of whether
you want to monitor or to operate, too,
the host computer has PS/2 or USB interfaces,
the video signal is analog (VGA) or digital (DVI),
the Thin Client Ex system can be used in all of these cases.

3.1
For system functionality, please also refer to the information on the KVM box in
Chapter 6.
Conditions for the host computer
The Thin Client Ex system can support all kinds of host computers, but these have to fulfill
certain minimum requirements:
These are:
The host computer should support USB pointer devices. As an alternative, the PS/2
interface can be used.
The screen resolution of the host must not exceed that of the Thin Client Ex station. This
would mean 1024x768 pixels for the 38 cm (15") Thin Client Ex device and 1280 x 1024
pixels for the 48 cm (19") device.
The DVI or VGA video output of the host computer has to correspond to one of the VESA
standard resolutions listed in the table below. For an optimum image quality the host
computer's resolution should be the same as that of the Thin Client Ex station.
VESA resolution (pixels)
640 X 480
800 x 600
1024 x 768
1152 X 864

3.2
System Function and Description
Standard application Thin Client Ex system
The standard application of the Thin Client Ex system is a direct Ethernet connection via the
KVM box to the host PC. In turn, this host PC is connected to the KVM box (5x6-KVM-digital)
via a DVI cable for the video signal and a USB cable for mouse and keyboard function.
If all components have been properly connected, the Thin Client Ex station will display the
screen contents of the host PC automatically after having been switched on. The (virtual)
keyboard, any pointer devices connected to the Thin Client Ex device and the touch screen
(after calibration) of the Thin Client Ex device will also work immediately. No further settings are
required for this standard application.
If the host computer has no DVI video signal, the KVM box can also be connected via a VGA
video signal. In this case, however, each host PC resolution used requires a video calibration of
the KVM box.
As an alternative, if the host PC has no USB support for pointer devices and keyboard, the PS/2
connection of the KVM box can be used for the connection of these.
If the "local" functionality of the KVM box should also be used with pointer device and keyboard,
this needs to be connected via the PS/2 interface.


Software Thin Client Ex
Functional expansion of the Thin Client Ex system
The Thin Client Ex systems standard application can be expanded in functionality by adding
various options. This is possible for all connection versions with the KVM box.
Functional expansions are:
Local operation of the host computer
Audio support
Remote media connection
3.3.1
Local operation of the host computer
As an alternative to operating the host computer via the Thin Client Ex station this can also be
done locally. For this, connect the screen, pointer device and keyboard in question to the KVMA
connection field called "Lokal"
(name on the KVM box: MOUSE/KEYBOARD/MONITOR/SPEAKER).

For the connection of devices to the "Lokal" KVMA connection field of the KVM box,
please also refer to Section 6.6.5 KVMA connection field "Lokal".
The keyboard connected to the local KVMA connection field of the KVM box can also be used
to call up the configuration menu of the KVM box. This is only necessary for configurations that
differ from the standard (e.g. for setting the IP address of the KVM box).
3.3.2
Remote media connection
A USB Flash-Drive (max. 2GB) can be connected to the Thin Client Ex station, making data
available directly on the host PC in the hazardous area. This requires a USB connection
between the KVM box and the host PC.
The Thin Client Ex device can be fitted with an additional USB cable (VB-USB-Plug), providing it
with an external USB(i) plug to which this USB Flash-Drive can be connected.
Pleae note that in hazardous areas you may only use an intrinsically safe USB FlashDrives !

For more information, please refer to Section 6.6.4 Remote USB-Medium.

Do not connect any CATx interfaces with RJ-45 connectors to other epuipment which
does not correspond to its associated function, such as telecommunications equipment.
The KVM box is not connected to earth and may therefore not be used for applications
that require this or a galvanic connection.
Do not attempt to repair the KVM box yourself.
Both the KVM box and the associated power supply unit warm up during operating !
Please ensure sufficient air can circulate around the components.
Caution !
The power supply unit contains conducting parts.
There are no parts that require servicing inside the power supply unit. Do not remove the
housing !
Connect the power supply unit to a socket close to the KVM box.
The power supply unit may only be replaced by equivalent units tested by the
manufacturer !
You must stop using the power supply unit as soon as you notice any damage to the
housing or when it is no longer working properly !
Wherever possible avoid parallel wiring of communication and live cables.
Use screened cables for communication lines to prevent electromagnetic interference.

Assembly and disassembly
The KVM box can be installed as a table-top unit. Four rubber feet can be glued to the bottom of
the KVM box for table-top mounting.

Please ensure that there is sufficient extra space for cabling.

While the LOC LED is flashing the operation from the Thin Client Ex station is disabled.
After an interval of 3 seconds this is re-enabled.
While the REM LED is flashing, the operation from the local host PC is disabled. After an
interval of 3 seconds this is re-enabled.
If more than one Thin Client Ex station is connected to this KVM box, the VNC LED will
only go out when the last Thin Client Ex station is no longer connected.

Connection options
The KVM box has two connection fields: one for the connection to the host PC, and one for the
connection of the local operating unit.
For the connection to the host PC, use the KVMA connection field called "Host-PC" (name
on the KVM box: TO LOCAL COMPUTER) (red field no. 1).
For the connection to the local operating unit, use the KVMA connection field called
"Lokal" (named MOUSE/KEYBOARD/MONITOR/SPEAKER on the KVM box itself) (red
field no. 2).
The two Sub-D connectors of the KVM box have no function and are not required.
Numbered view:
6.6.1
Video connection
The video socket (blue no. 4) can be used for both analog (VGA) and digital (DVI) video
connections. The digital video signals of the host PC are fed into the KVM box via the existing
DVI-I socket.

To establish this connection, use the video cables included in the delivery.

Mouse and keyboard
A USB connection betwee the kexboard/mouse socket (blue no. 5) and the host PC is required
for the transfer of mouse and keyboard signals from the Thin Client Ex station to the host PC. A
standard USB cable type A-B can be used for this.
As an alternative to this USB connection you can also use a PS/2 connection for mouse (blue
no. 6) and keyboard (blue no. 7) Here, too, you can use standard, commercially available PS/2
cables.
This PS/2 alternative should only be used if the host computer does not support USB keyboards
and mouses, because the PS/2 connection has certain disadvantages.
These are:
An initial mouse calibration at the Thin Client Ex station is required for each host
screen resolution used to operate the touch screen, because the PS/2 protocol does
not support absolute positioning.
If the Thin Client Ex station is operated in touch screen mode, the cursor needs to be
re-synchronised. This is particularly important if other pointer devices are also
connected directly to the host computer. This constellation should be avoided.
6.6.3
Remote USB medium
The KVM box can virtualize USB Flash-Drives connected to the Thin Client Ex station and make
them available to the host computer as if they were attached to it. This works with USB FlashDrives with a maximum memory of 2 GB.
The manufacturer provides an explosion-proof USB Flash-Drive for hazardous areas. Apart
from these, standard USB Flash-Drives may be used.
If the virtual medium function is required, the virtual medium interface (blue no. 9) of the KVM
box must be connected to an unused USB interface at the host computer. A standard USB
cable type A-B can be used for this.
6.6.4
KVMA connection field "Lokal"
Use the "Lokal" KVMA connection field (named MOUSE/KEYBOARD/MONITOR/SPEAKER on
the KVM box itself) (red field no. 2) for the connection of components (monitor, keyboard,
mouse and speakers) for the local operation of the host computer in addition to the remote
access. For this, connect the components to their corresponding interfaces.
Please note the following:
Mouse and keyboard connections to the "Lokal" KVMA connection field have to be the
same as the mouse and keyboard connections from the KVM box to the host PC.
All connections have to be either via USB or via PS/2.
The connection type of the local monitor can be chosen regardless of the type of video
connection of the KVM box to the host computer.
Local and remote control of the host PC are mutually exclusive so that they cannot be
used simultaneously.
6.6.5
Purely visual connection
Establishing a connection that merely enables the visual display of the host PC's screen
contents at the Thin Client Ex device is the simplest connection version. In addition to the power
supply, this only requires the Ethernet connection to the Thin Client Ex station and the video
connection to the host PC.
