Chapter 1: Specifications

1. Specifications

1.1 Interfaces

1.1.1 DVI-D Single Link

The video interface supports the DVI-D protocol. All signals that comply with the DVI-D Single-Link specification can be
transmitted. This includes, for example, monitor resolutions such as 1920 x 1200 @ 60 Hz, Full HD (1080p), or 2K HD (up to
2048 x 1152). Data rate is limited to 165 Megapixels per second (MPixel/s).

1.1.2 DVI-I Single Link

The video interface supports the DVI-I protocol. All analog (VGA) or digital (DVI) signals that comply with the DVI-I Single-Link

specification can be transmitted. This includes monitor resolutions for VGA up to 1920 x 1200 @ 60 Hz, and monitor resolutions

for DVI-I up to Full HD (1080p) or for DVI-D 2K HD (up to 2048 x 1152). Data rate is limited to 165 MPixel/s.

NOTE: Transmission of interlaced video signals, such as 1920 x 1080i, cannot be guaranteed.

1.1.3 USB-HID

Our devices with an USB-HID interface support a maximum of two devices compliant with the USB-HID protocol. Each USB-HID
port provides a maximum current of 100 mA.

Keyboard

Compatible with most USB keyboards. Certain keyboards with additional functions may require custom firmware to operate.
Keyboards with an integral USB hub (such as Mac® keyboards) are also supported.

Mouse

Compatible with most 2-button, 3-button, and scroll mice.

Other USB-HID devices

The proprietary USB emulation also supports certain other USB-HID devices, such as specific touch screens, graphics tablets,
barcode scanners or special keyboards. Support cannot be guaranteed, however, for every USB-HID device.

NOTE: Only two USB-HID devices are supported concurrently, such as keyboard and mouse or keyboard and touch screen. A hub

is allowed, but it does not increase the number of HID devices allowed. You can also use Extenders with an addiitonal HID
channel.

To support other USB ”non-HID” devices, such as scanners, Web cams, or memory devices, choose our devices with transparent
USB support.

1.1.4 USB 2.0 (transparent)

DKM Modular 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 with high-speed USB (max. 480 Mbps).

Each USB 2.0 port provides a maximum current of 500 mA (high power).

1.1.5 RJ-45 (Interconnect)

For CATx device communications, the extender 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.

NOTE: DKM Extenders do not support TCP/IP protocol: Do not run the extenders through network equipment such as routers,

switches, or hubs.

Page 8

724-746-5500 | blackbox.com

AC X1T

Chapter 1: Specifications

1.1.6 Fiber SFP Type LC (Interconnect)

The communication of fiber devices is performed via Gigabit SFPs that have to be connected to suitable fibers fitted with type LC
connectors (see Chapter 1.2.2).

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).

When handling, take care not to damage devices.

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 19,200.

The CON Unit is cabled as DTE (Data Terminal Equipment, such as CPU output) and can be connected directly to DCE (Data
Communication Equipment) devices.

• A touch screen can be connected directly to the CON Unit.

• To connect to a serial printer (or any other DTE instead of DCE device), you need a null-modem cable (cross-over cable)

between the CON Unit and the device.

Operation of several devices:

The serial interface transmits six signals (three for each direction). Normally, four of the six signals are handshake signals (in
addition to RxD and TxD). The following configurations, however, are possible 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 the printer and PC.

Table 1-1. Serial interface specifications.

Specification Description

Connection Format DTE (Data Terminal Equipment)

Speed Up to 19,200 baud

Data Format Format independent

Data Transmission

Traffic Control

• RxD (Receive Data)

• TxD (Transmit Data)

The following signals are transmitted (hardware handshake):

• RTS (Request to Send)

• CTS (Clear to Send)

• DTR ( Data Terminal Ready)

• DSR ( Data Set Ready)

1.1.8 Analog Audio Interface

The Analog Audio option supports a bidirectional stereo audio transmission, in nearly 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.

AC X1T

724-746-5500 | blackbox.com

Page 9

724-746-5500 | blackbox.com

Chapter 1: Specifications

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 with 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 do the pre-amplification of the microphone as well. Open the CON Unit, locate the “MIC” jumper on

the audio board and close the pins.

Table 1-2. Analog audio specifications.

Specification Description

Transmission Format Digitized virtually CD quality audio (16-bit, 38.4 kHz)

Signal Level Line-level (5-volt pk-pk maximum)

Input Impedance 47 kOhm

Connections CPU Unit (2) 3.5-mm stereo audio plug (audio in and audio out)

Connections CON Unit (2) 3.5-mm stereo audio plug (audio in and audio out)

1.1.9 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.

Up to three sinks can be connected to the CON Unit. The signal is available at all outputs concurrently.

DKM Compact Extenders with digital audio option include a built-in sample rate converter that provides predefined sample
frequencies at the CON unit’s output.

The user can set the following parameters directly via a configuration file:

• Activate or deactivate sample rate converter

• Set sample frequency of the sample rate converter. The following sample frequencies are available:

– 32.0 kHz

– 44.1 kHz

– 48.0 kHz

– 96.0 kHz

• Avoid routing CATx cables along power cables.

• If the site has 3-phase AC power, make sure that CPU Unit and CON Unit are on the same phase.

CAUTION: To maintain regulatory EMC compliance, you must use correctly installed shielded CATx cable throughout the

interconnection link. Also, all CATx cables need to carry ferrites on both cable ends close to the device.

Type of Interconnect Cable

The DKM Compact Extender requires interconnect cabling specified for Gigabit Ethernet (1000BASE-T). The use of solid-core
(24 AWG), shielded, CAT5e (or better) is recommended.

Table 1-4. CATx interconnect cable specifications.

Parameter Description

1.3 Supported Peripherals

1.3.1 USB-HID Devices

The DKM Modular 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 touchscreens may also be compatible.

It is not possible to guarantee support for all available USB-HID devices. In certain cases, you may need custom firmware.

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

DKM Modular 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. Please

contact Black Box Technical Support at 724-746-5500 or [e-mail] if any issues are found.
