1.1.6 FIBER SFP TYPE LC (INTERCONNECT)
Communication of fiber devices is performed via Gigabit SFPs that are connected to suitable fibers fitted with connectors type LC.
NOTE: The correct function of the device can only be guaranteed with SFPs provided by Black Box.
CAUTION: SFP modules can be damaged by electrostatic discharge (ESD). Please consider ESD handling specifications.
1.1.7 SERIAL INTERFACE
The serial interface option supports a full-duplex transmission with a real hardware handshake up to a Baud rate of 115,200 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 touchscreen can be connected directly to the CON Unit.
To connect to a serial printer (or any other DTE instead of a DCE device), you need a null-modem cable (crossed cable) between CON Unit
and the device.
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.

1.1.9 ANALOG AUDIO INTERFACE
The analog audio option supports a bidirectional stereo audio transmission, in near-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 to 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.
NOTE: The CON Unit can also provide pre-amplification of a microphone. Open the CON Unit, locate the MIC jumper on the audio board and
close the pins.

1.1.10 DIGITAL AUDIO INTERFACE
The digital audio option supports the unidirectional transmission of digital audio data.
Up to three sources can be connected to the CPU Unit. The active source is transmitted. If several sources are active, the XLR signal takes
priority, otherwise the first active signal.
The three connectors on the CON Unit provide concurrent digital audio.
KVM Extenders with the digital audio option include an built-in sample rate converter that provides predefined sample frequencies at the
output of the CON Unit.
The user can set directly the following parameters by using a configuration file:
Activate or deactivate sample rate converter in the Config.txt file on the flash drive of the KVM Extender.
If the sample rate converter is activated, the following characteristics are valid: 140 dB dynamic range and -120 dB total harmonic distortion +
noise.
Set sample frequency of the sample rate converter by writing the parameter in a new line. The following sample frequencies are available:
– 32.0 kHz (write SRC32000 in Config.txt file of the CPU unit)
– 44.1 kHz (write SRC44100 in Config.txt file of the CPU unit)
– 48.0 kHz (write SRC48000 in Config.txt file of the CPU unit)
– 96.0 kHz (write SRC96000 in Config.txt file of the CPU unit)
You can use a delay for converting the sample rate. The time is set in milliseconds and separated from the parameter for the sample rate by
a semicolon (e.g. SRC44100;12). You can set the following delays for the sample rates:
– 32.0 kHz: 3 - 60 ms
– 44.1 kHz: 2 - 44 ms
– 48.0 kHz: 2 - 40 ms
– 96.0 kHz: 1 - 20 ms
To deactivate the sample rate converter, write SRC_NONE in the Config.txt file of the CPU unit.

1.3 SUPPORTED PERIPHERALS
1.3.1 USB-HID DEVICES
The KVM Extender will support most USB-HID devices, including the vast majority of keyboards and mice currently on the market. Many
other kinds of HID devices such as bar-code scanners and touch screens may also be compatible.
It is not possible to guarantee support for all available USB-HID devices. In certain cases, custom firmware may be required.
USB-HID (and other) devices that are not supported as standard will normally operate with our devices featuring transparent USB
support.
NOTE: Concurrent operation of more than two USB-HID devices is not possible even if you use a USB hub.
1.3.2 USB 2.0 DE VICES
KVM Extender models featuring a transparent USB 2.0 connection use Extreme USB Technology.
This technology supports all types of USB 2.0 devices, however, we cannot guarantee compatibility with every device on the market.
Contact Black Box Technical Support at 877-877-2269 or [email protected] if any issues are found.

CHAPTER 2: INTRODUCTION
2. INTRODUCTION
This manual describes how to install your KVM Extender, how to operate it, and how to perform troubleshooting.
2.1 DESCRIPTION
The KVM Extender is used to increase the distance between a source (computer, CPU) and its console (keyboard, mouse, and other
peripheral devices). The Extender is designed for use with CATx (Twisted Pair) interconnect cables or fiber interconnect cables.
The KVM Extender with CATx interconnect cables is unsuitable for connection between buildings where a fiber optic based
product should be used instead. You can use the KVM Extender with fiber interconnect cables in environments that are subject to
electromagnetic interference. Electromagnetic interference can limit the maximum distance and reliability of operation.
2.2 SYSTEM OVERVIEW
The KVM Extender consists of at least one CPU module and one CON module. The various modules install in a 2-, 4-. or 6-slot chassis at
the CPU site and at the CON site (CPU and CON Unit).
The CPU module connects directly to the source (computer, CPU) using the supplied cables.
The CON module connects to the console (monitor, keyboard and mouse).
The CPU Unit and the CON modules communicate with each other through the interconnect cables.

CHAPTER 4: CONFIGURATION
4. CONFIGURATION
4.1 TRANSMISSION PARAMETERS
The device operates with a proprietary compression method.
In the default configuration, the device adapts dynamically to monitor resolution and image content. This configuration is suitable for
almost all conditions and should only be modified if image quality is not fully satisfactory. In exceptional cases the displayed video image
may exhibit “frame dropping” (loss of single pictures) or color effects.
4.2 DDC SETTINGS
By default, the device transmits the factory preset DDC information to the CPU. This information is suitable in most cases.
Downloading of the DDC information of the console monitor can be performed during normal operation.
For special requirements, DDC information can be retrieved and uploaded as a binary file to both the CPU Unit and the CON Unit.
Connect your computer with a USB mini cable to the service port of the CPU Unit or CON Unit.
The data area of the unit is now accessible as a flash drive “Extender.”
Uploading DDC Information
Copy the binary file containing your specific DDC information to the flash drive of the CPU Unit or CON Unit.
The current DDC information is replaced.
Retrieving DDC Information
Copy the file “DDC-EDID.bin” on the flash drive of the CPU Unit to your computer.
To open the binary file, you have to install a suitable software, e.g. WinDDCwrite, on your computer. Contact your dealer for this purpose.
Reset to Factory DDC Information
Delete the file called “DDC-EDID.bin” on the flash drive of the CPU Unit. By deleting this file, the factory DDC Information is restored.

4.3 COMMAND MODE
During normal use, the console keyboard functions in the usual manner. However, for all KVM Extenders with USB-HID support, you can
set the keyboard into a Command Mode by using a specific Hotkey sequence. While in Command Mode, several functions are performed
via keyboard commands. To exit Command Mode, press <Esc>.
While in Command Mode, the Shift and Scroll LEDs on the console keyboard will flash.
NOTE: In Command Mode normal keyboard and mouse operation will cease. Only selected keyboard commands are available.
If no keyboard command is executed within 10 s after activating Command Mode, it will be automatically deactivated.
The following table lists the keyboard commands to enter and to exit Command Mode and to change the Hotkey sequence.

Reset Hotkey
To set a Hotkey back to default settings of the extender, press the key combination <Right Shift> + <Del> within 5 s after plugging in a
keyboard.
4.4 USB-HID GHOSTING
This function allows specific keyboard and mice descriptors (device descriptions) to be permanently stored in the CPU unit. This eliminates
the need to register and deregister the keyboard and mouse on an operating system each time there is a shared use of a source (computer,
CPU) by two or more consoles within a KVM matrix.
The next table lists the keyboard commands for the configuration of USB-HID Ghosting.

4.5 CONFIGURATION FILE
The KVM Extender contains a configuration file (Config.txt) to set specific parameters and to read out device and video information. You
can find it on the flash drive of the KVM Extender. The flash drive can be opened by a mini USB connection to a computer.
The configuration file can be edited with all common text editors.
NOTE: After setting a parameter, the KVM Extender needs to be restarted.
NOTE: To ensure correct identification and acceptance of the parameters, the start command #CFG has to be written into the first line of
the Config.txt file.

5. OPERATION
5.1 DOWNLOAD OF DDC INFORMATION
By default, data from the internal DDC list is reported to the source (computer, CPU). If these are not optimal settings for the display
device, the DDC information of the console monitor can be downloaded and stored internally. The devices have to be configured
accordingly.
On all KVM Extenders with USB-HID support, the user can load the DDC information of the console monitor via keyboard command under
operating conditions.
1. Enter Command Mode with the Hotkey.
2. Press the <a> key to download the DDC information of the console monitor.
The screen will go black for a short time.
At the same time Command Mode is closed and the keyboard LEDs return to previous status.
3. Restart the corresponding source (computer, CPU).
The video mode has been readjusted. Screen quality should be optimal. 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. Reloading is possible by repeating the operation.
5.2 PARALLEL OPERATION OF REDUNDANT CPU UNITS
CPU Units with a redundant connector for interconnect cables offer the possibility for a competing control by two connected CON Units.
Taking over control is performed using a keyboard and/or mouse. The release timer function determines the release time of the input
devices at one of the CON Units after that control can be taken over from the second CON Unit.
To configure a redundant CPU Unit for the operation with two parallel controlling CON Units, proceed as follows:
1. Connect a redundant CPU Unit to any source (computer, CPU) by using a mini USB connection.
2. Open the file “Config.txt” that is located on the appearing flash drive of the extender.
3. Activate the release timer by writing the parameter RELEASETIME=n into the second line. The variable “n” defines the time in seconds
and has to be replaced by the numbers 0 to 9 (e.g. RELEASETIME=5). If this parameter is not activated at all, the release time is set to 2
seconds by default. The parameter RELEASETIME=X deactivates the shared operation.
4. Save your changes.
5. Reboot the CPU Unit.
