1.1.4 USB 2.0 (TRANSPARENT)

KVM Extender models with transparent USB 2.0 support allow the connection of all types of USB 2.0 devices (without restriction). USB 2.0 data transfer is supported, depending on the upgrade module, with USB high speed (max. 480 Mbit/s) or USB embedded (max. 36/100/480 Mbits, depending on extender type).

Each USB embedded port provides a maximum current of 500 mA (high power). When using a USB high speed interface with 4 USB ports, respectively 2 connectors provides a maximum of 500 mA (high power) and 2 connectors a maximum of 100 mA.

1.1.5 RJ-45 (INTERCONNECT)

Communication between CATx devices requires a 1000BASE-T connection.

Connector wiring must comply with EIA/TIA-568-B (1000BASE-T), with RJ-45 connectors at both ends. All four cable wire pairs are used.

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.

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.

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.

3.4 OVERVIEW UPGRADE MODULES

Section 2.3.4 lists available upgrade modules for the KVM Extender.

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 .

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 + 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.

CONFIGURATION COMMANDS FOR USB-HID GHOSTING

FUNCTION KEYBOARD COMMAND

Writes the device descriptions of the input devices connected to the CON Unit into the CPU Unit. Activating the emulation in the CPU Unit.
Activates the emulation of already stored device descriptions in the CPU Unit
Deactivates the emulation of active device descriptions in the CPU Unit. The input devices connected to the CON Unit will be now passed transparently to the source (computer, CPU).
Deactivates the emulation of active device descriptions in the CPU Unit. Deletes the descriptions out of the CPU Unit. The input devices connected to the CON Unit will be now passed transparently to the source (computer, CPU).

NOTE: When using a USB combo device as a USB-HID input device, switching to a CPU Unit with activated USB-HID Ghosting may cause limited functionality.

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 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.

1. 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.

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.

NOTE: When using redundant CPU Units in combination with a KVM matrix, the function of competing control will be automatically deactivated in the extender and will have to be performed by the KVM matrix.
