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.

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 Megapixels per second.

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 touchscreens, graphics tablets,
bar-code 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 touchscreen. A hub

is allowed, but it does not increase the number of HID devices allowed.

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 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.

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).

Page 8

724-746-5500 | blackbox.com

AC X1MT

Chapter 1: Specifications

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

• A touchscreen can be connected directly to the CON module.

• 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 module 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 module.

Stereo audio can be transmitted bidirectionally at the same time.

Connection of a microphone:

Connect the microphone to the “audio” input of the CON module. There are two ways to establish this connection:

• The output of the CPU module is connected with the microphone input of the sound card (red). Adjust the sound card to

provide an additional amplification (20 dB).

AC X1MT

724-746-5500 | blackbox.com

Page 9

724-746-5500 | blackbox.com

Chapter 1: Specifications

• The output of the CPU module 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 module can do the pre-amplification of the microphone as well. Open the CON module, 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 peak-peak 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 module. 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 module. The signal is available at all outputs concurrently.

DKM Modular Extender with digital audio option includes a built-in sample rate converter that provides predefined sample
frequencies at the CON module’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

Chapter 2: Overview

2. Overview

2.1 Application

The DKM Modular Extender is used to increase the distance between a source (computer, CPU) and its console (keyboard, mouse,
and other peripheral devices). It’s designed for use with CATx (twisted-pair) interconnect cables or fiber interconnect cables.

The DKM Modular Extender with CATx interconnect cables won’t work between buildings where you should use a fiber optic
based product instead.

The DKM Modular Extender with fiber interconnect cables also works with applications in environments with a great deal of
electromagnetical interference. Electromagnetical interference can limit the maximum distance und reliability.

The DKM Modular Extender is fully compatible with the DKM Compact Extender (ACX1T/ACX1R series).

It’s designed to work in point-to-point applications as well as through a ServSwitch DKM or ServSwitch DKM FX crosspoint
switch.

2.2 System Overview

The DKM Modular Extender consists of at least one CPU module and one console (CON) module. A 2-, 4-, or 6-slot modular
case holds the modules. The DKM Modular cases (2-slot, 4-slot, or 6-slot) are installed at the CPU (transmitter) and CON (receiver)
site.

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 module and the CON modules communicate with each other through the
interconnect cables. Figure 2-1 shows a typical system application. Table 2-1 describes the components shown in the diagram.

Chapter 4: Configuration

4. Configuration

4.1 Transmission Parameters

The device operates with a proprietary compression method. In its default configuration, the device adapts dynamically to monitor
resolution and image content. This configuration works in almost all conditions. Modify it only if image quality is not fully
satisfactory.

NOTE: In exceptional cases, detached "frame droppings" (loss of single pictures) or color effects can appear.

4.2 DDC Settings

By default, the device sends the factory preset DDC information to the CPU. This information works in most cases.

During normal operation , you can downoad the console monitor’s DDC information (see Chapter 5).

For special requirements, DDC information can be retrieved and uploaded as a binary file at both the CPU module and the CON
module.

Connect your computer with a USB Mini cable to the CPU module’s or CON module’s service port.

You can now access the data area of the unit as a flash drive “Extender.”

Uploading DDC Information

Copy the binary file containing your specific DDC information to the flash drive of the CPU module or CON module.

The current DDC information is replaced.

Retrieving DDC Information

Copy the file "DDC-EDID.bin" on the flash drive of the CPU module to your computer.

To open the binary file, you have to install a suitable software, for example, WinDDCwrite (Download), on your computer.

Reset to Factory DDC Information

Delete the file called “DDC-EDID.bin” on the flash drive of the CPU module. 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 LEDs
Shift and Scroll on the console keyboard will flash.

NOTE: In Command Mode, normal keyboard and mouse operation will cease. Only selected keyboard commands are available.

Table 4-1 lists the keyboard commands to enter and to exit Command Mode and to change the hotkey sequence.

Table 4-1. Keyboard commands.

Function Keyboard Command

Enter Command Mode 2x <Left-Shift>/Hotkey

Chapter 5: Operation

5. Operation

Download of DDC Information

By default, data from the internal DDC list is reported to the source (computer, CPU). If these settings do not lead to a satisfying
result, you can download and store the console monitor’s DDC information internally. The devices must be configured accordingly
(see Section 4.2).

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” (see Section 4.2).

2. Press the <a> key to download the DDC information of the console monitor.

The screen goes black for a short time. Status LEDs on both CON and then CPU modules will flash to indicate the copy and store
process.

At the same time Command Mode is closed and the keyboard LEDs return to previous status.

This re-adjusts the video mode. You should have optimal screen quality. 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.

To re-load the DDC information, repeat the operation.
