2. Product Overview
2.1 Features and Benefits
The ServSwitch DTX5000 provides users with a full computer desktop experience from
anywhere on the corporate TCP/IP network, while maintaining the computers securely
housed in a corporate data center. This desktop experience includes access for the desktop
user to keyboard, mouse, video, audio and USB mass storage devices.
The ServSwitch DTX5000 system consists of:
• The DTX5000-T that connects externally to the remote computer
• The DTX5000-R that is located at the user’s desk
Figure 2-1. ServSwitch DTX5000 Basic System
DTX5000-T (Transmitter)
The DTX5000-T connects to the video, audio and USB ports of the computer and is
available as a Transmitter that attaches externally to the remote computer.
The Transmitter is attached directly to the remote computer and draws its power directly
from two USB ports on the remote computer. This removes the need for additional power
supply connections at the rack.
NOTE:
If the remote computer cannot supply the required power or if two USB connections are not available, an
external power supply can be obtained from Black Box.
The Transmitter captures, compresses and encrypts the computer’s media streams and
transmits them to the DTX5000-R (Receiver) over a standard TCP/IP network.

SERVSWITCH DTX5000 USER GUIDE
12
DTX5000-R (Receiver)
The Receiver enables the desktop user’s keyboard, mouse, video, audio and mass storage
devices to connect to the ServSwitch DTX5000 system. It is available as a desktop user
station.
Automatic Connection
When the Receiver is powered up, a connection is automatically established with the
remote computer via the Transmitter. No intervention is required from the user. See
“Accessing the System” on page 21.
Ethernet addressing
The Receiver and the Transmitter are IP-addressable devices; this gives you the flexibility
to locate back-racked computers anywhere within your enterprise and at any distance from
your desktop users. The Receiver and the Transmitter use standard network protocols to
transfer data streams between the remote computer and the peripheral devices located at
the user’s desk. The ServSwitch DTX5000 system can operate on a network connection of
10 Mbps, 100 Mbps or 1 Gbps. For optimum performance a 1 Gbps connection is
recommended. For more information see Chapter 3.
Multiplatform support
The Transmitter is connected to the remote computer via USB connectors. This enables
the ServSwitch DTX5000 system to interoperate seamlessly with PC, Sun and Macintosh
target computers. PC, Sun and Macintosh USB keyboards can be connected to the
Receiver. PS/2 keyboards and mice can also be used.
You can attach the ServSwitch DTX5000 system to computers running the following
operating systems:
• Microsoft Windows
• Redhat Linux
•Solaris
•MacOS
The default keyboard drivers for these operating systems are fully supported by the
ServSwitch DTX5000 system.
Flexible installation
The Receiver can be desk mounted or mounted on the back of a monitor. Installation
requires no new drivers or software. Standard UTP cabling makes installation simple and
keeps costs low.
Security
The ServSwitch DTX5000 system supports Secure Sockets Layer (SSL) over a TCP/IP
connection. All media streams transmitted between the Receiver and the Transmitter are
encrypted. In addition, password protection is provided to control access to all
administration functions. For example, network configuration information, see “Access
Control” on page 29.
OSD
The Receiver includes an On-Screen Display (OSD) that allows you to view information
about the configuration of your ServSwitch DTX5000 system. See “The OSD” on
page 22.

CHAPTER 2: PRODUCT OVERVIEW
13
Operations administration and maintenance
The Receiver incorporates a Serial Interface menu that allows you to perform
administration and maintenance tasks for both the Receiver and the Transmitter. Examples
of tasks you can perform include, configuration of network settings and firmware Flash
upgrades. See “The Serial Interface” on page 23.
Flash upgradeable
Upgrade your firmware at any time using the XMODEM or HTTP protocols to ensure that
your ServSwitch DTX5000 system is always running the most current version available.
Both the Transmitter and the Receiver are Flash upgradeable. See “Flash Upgrading your
ServSwitch DTX5000 System” on page 33.
Support for keyboards and mice
USB and PS/2 keyboards and mice are fully supported by the ServSwitch DTX5000
system. The system also allows for mix and match of USB and PS/2 peripherals. For
example, it is possible to use a USB keyboard in conjunction with a PS/2 mouse. The
default keyboard and mouse drivers of the remote computer are fully supported. This
enables the ServSwitch DTX5000 system to support 2-, 3- and 5-button mice with scroll-
and tilt-wheel capability. Composite mouse and keyboard devices are also supported.
USB support
The ServSwitch DTX5000 system is compatible with the USB 2.0 standard, and provides
support for low-, full- and high-speed USB devices. The Receiver provides four USB 2.0
compliant ports that can be used to access USB removable drives and CD-ROM drives,
keyboards, mice and USB hubs. Hot plugging of USB devices is supported.
NOTE:
A hub cannot be used to expand the number of USB ports available.
Virtual media
Mass storage devices, such as removable drives and external CD-ROM drives, can be
attached to the Receiver and will function as if they are directly connected to the remote
computer. Data can be both read from and written to these mass storage devices. You can
connect both a removable drive and an external drive at any one time to the Receiver.
NOTE:
It is not possible to connect two mass storage devices of the same type to the Receiver at any one time.
For example, you cannot connect two removable drives to the Receiver.
The transfer speed between the mass storage device and the remote computer is dependant
on the Ethernet network. A 1 Gbps connection is required for high-performance virtual
media transfer. The system is capable, however, of operating over a 100 Mbps Ethernet
connection. By default, 20 per cent of the available connection bandwidth is allocated to
virtual-media transfer.
The following mass storage devices are supported:
• Removable drives
• External USB hard drives
• External USB CD-ROM drives
Hot plugging of USB mass storage devices is supported.

SERVSWITCH DTX5000 USER GUIDE
14
NOTE:
The ServSwitch DTX5000 system supports the default drivers for mass storage devices.
Audio
The ServSwitch DTX5000 system supports CD-quality stereo from the remote computer
to peripheral speakers, and mono-quality audio from a peripheral microphone to the
remote computer.
Video
Video of 24-bit color depth up to a resolution of 1280 x 1024 at 60 Hz is supported by the
ServSwitch DTX5000 system. Both CRT and flat-panel LCD monitors are supported, and
can be connected to the ServSwitch DTX5000 system via a DVI-I video connector. VGA
monitors can be attached to the system by using a DVI to VGA adaptor. The system
supports DDC version 2B.
Reduced Total Cost of Ownership (TCO)
The ServSwitch DTX5000 system delivers significantly lower TCO when compared to
traditional distributed computer systems. Centralized maintenance enables greater security
and convenience as well as reduced workplace disruption and down-time. IT
administration costs are also significantly reduced by housing all PCs in one central
location. Relocating the computer away from the user frees up valuable office space and
reduces desktop power and heating, ventilation and air conditioning (HVAC)
requirements.
2.2 Safety Precautions
To avoid potential video and/or keyboard problems when using Black Box products:
• If the building has 3-phase AC power, ensure that the computer and monitor are on
the same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe
the following precautions:
• Do not use a 2-wire extension cord in any Black Box product configuration.
• Test AC outlets at the computer and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the computer and monitor. When using a
backup Uninterruptible Power Supply (UPS), power the computer and the
Transmitter off the same supply.
NOTE:
The AC inlet is the main disconnect.
