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.

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.

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 DEVICES
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 [e-mail] 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.

1 Source (computer, CPU)
2 KVM Extender CPU Unit
3 Interconnect cable
4 KVM Extender CON Unit
5 Console (monitor, keyboard, mouse)
6 Second monitor (option, only with Dual-Head devices)
