ServSwitch Brand DVI-D USB KVM-over-Fiber Extender
2. Overview
2.1 Introduction
The DVI-D USB KVM over Fiber Optic Extender consists of a console unit and a
computer unit. It enables you to remotely access and control a computer or KVM
switch up to 6400 feet (2000 m) away from using only fiber optic cable.
The extender optimizes the digital display up to a maximum resolution of Full HD
(1920 x 1080)/WUXGA (1920 x 1200)/UXGA (1600 x 1200). For cascaded applica-
tions, the dedicated Mask Hotkey switch masks the master KVM extender level,
enabling users to directly configure the slave level KVM switch as if the user were
sitting in front the slave KVM switch. This saves time, prevents errors, and makes
the hotkey configuration more predictable.
This KVM extender includes dual-user access, the ability to control multiple
computers through cascading with a KVM switch, push button for switching
control, front-panel LED for status indication, hotkey control and mask hotkey
switch for easy computer access, serial interface for instant data transfer, HDCP
compliance, Blu-ray display support, and audio jack (speaker + microphone)
for broadcasting. Besides, it is fully compatible with most popular monitor screen
resolutions such as XGA, SXGA, UXGA, WSXGA all the way to Full HD, WUXGA
system.
Ideal for transmission security, the extender eliminates electromagnetic radiation
emission. Use it for a variety of KVM extension applications, including in medical,
military, industrial, and high electromagnetic interference (EMI)/radio frequency
interference (RFI) environments where real-time, high-resolution audio/video
transmission is essential. The extender also enables you to secure the computers
and valuable data or manage them both in remote and local sites. No software
or DIP switches are required, just plug and play.

Chapter 3: Installation
3. Installation
3.1 Using Fiber Optic Cable
1. Use multimode fiber optic cable (50/125 and 62.5/125) terminated with SC
connectors to link the computer unit and the console unit. Table 3-1 lists
applicable specifications.
Table 3-1. Fiber optic cable specifications.
Cable Diameter 50/125 µm 62.5/125 µm
Video Signal 1080i 1080p 1080i 1080p
Maximum Cable Length 6400 ft./ 3200 ft./ 2240 ft./ 1120 ft./
2000 m 1000 m 700 m 350 m
2. Use different cable lengths according to the application environment; however,
the maximum cable length should be less than 6400 feet (2000 meters).
Otherwise, the video resolution signal might degrade.
3. Check the cable length to make sure the cable being pulled is long enough for
the run to prevent having to splice fiber. Try to complete the installation in one
pull. Before installation, assess the route carefully to determine the methods of
installation and obstacles likely to be encountered.
4. Do not exceed the cable bend radius. Fiber optic cable can be broken when
kinked or bent too tightly, especially during pulling.
5. Do not twist the cable. Twisting the cable can stress the fibers. Tension on the
cable and pulling ropes can cause twisting.
6. Don’t look into the ends of any fiber optic cables. Invisible laser radiation might
damage your eyes.
7. Connector and splice loss is caused by a number of factors. Loss will be mini-
mized when the number of connections and splices is reduced, the two fiber
cores are identical and perfectly aligned, the connectors or splices are properly
finished, and no dirt is present.
8. Although most fiber optic cables are not conductive, any metallic hardware
used in fiber optic cabling systems (such as wall-mounted termination boxes,
racks, and patch panels) must be grounded.

Page 16 724-746-5500 | blackbox.com
ServSwitch Brand DVI-D USB KVM-over-Fiber Extender
9. Conductive cables require proper grounding and bonding for applicable
conductors.
10. Carefully inspect all fiber optic components for damage and test it for continu-
ity or loss if you suspect damage.
11. Move small, lightweight spools of fiber optic cable by hand. Move larger reels
with appropriate lifting equipment or use two or more installers skilled in the
moving operation.
12. Follow the cable manufacturer's recommendations. Fiber optic cable is often
custom designed for the installation and the manufacturer may have specific
instructions on its installation.
3.2 Before Installation
NOTE: See Figure 2-5 for a sample installation.
1. Make sure that all the devices you will connect are properly grounded.
2. Before installation, make sure that all the devices you will connect to this
system are powered off.
3. The KVM Extender is HDCP compliant. Use an HDCP-compliant display when

ServSwitch Brand DVI-D USB KVM-over-Fiber Extender
4.2 Selecting Computers Using Push Buttons
The Computer Unit and the Console Unit’s front panels each have a push button.
Push these buttons in sequence to switch between operation modes.
4.2.1 Push Button on the Console Unit
The button on the front panel of the Console Unit can be used to switch modes
by following the sequence below:
Local On—>Remote On—>Local On—>Remote On
Local On: The Local LED lights to indicate that the console unit is taking control of
its local computer.
Remote On: The Remote LED lights to indicate that the console unit is remotely
taking control of the Computer Unit.
4.2.2 Push Button on the Computer Unit
Through pressing the button, three modes will be generated in the sequence as
shown below:
Auto—>Local On—>Remote On—>Auto—>Local On—>Remote On
Auto:
1. The Remote and Local LEDs flash alternately.
2. The system is now waiting for the Console or the Computer Unit to take
control. The control priority is on a first-come, first-served basis.
For example, once the keyboard or mouse of the Computer Unit is active, the
Local LED will light and the Remote LED will go off. This status indicates that the
Computer Unit is now taking control on its local computer or KVM switch, and
vice versa for the Console Unit. In Auto mode, you can preset the duration of
latch time for taking control to 5, 15, 30, or 60 seconds via hotkeys, which
enables the Computer or Console Unit to resume control again via any keystroke
or mouse activity if the latch time is due and the status returns to the “Auto”
mode.
In “Auto” mode whenever the Computer Unit or Console Unit detects any activity
from the keyboard, mouse buttons, or mouse’s scroll wheel, the Computer Unit or
Console Unit immediately takes control of the system.
Local: The Local LED lights when the computer unit is taking control on its local
computer or KVM switch. In this case, the user in Console Unit can identify this
status from the flashing of 3 LEDs (Num, Caps, and Scroll Lock) on the keyboard.
Remote: The Remote LED lights when the system is remotely controlled by the
Console Unit.

Chapter 4: Operation
4.3 Selecting Computers Using Keyboard Hotkey Commands
A hotkey command is a short key sequence that selects a computer, activates a
computer scan, etc. The KVM extender interprets keystrokes for hotkeys all the
time no matter what the connection pattern is.
Standard Mode is defined as the state of the KVM extender without any
connection to any KVM switch.
Compatibility Mode is defined as the state of the KVM extender with
connection(s) to KVM switch(es).
In Command for Switch Mode, users can switch modes between Standard and
Compatibility by pressing the hotkey command [left-Ctrl + left-Ctrl + Alt+E]. The
unit then generates one beep to confirm Standard Mode or two beeps to confirm
Compatibility Mode.
Leading Code
In Standard Mode, a hotkey command starts with the leading code
[left-Ctrl + left-Ctrl] followed by one or two more keystrokes.
In Compatibility Mode, a hotkey command starts with the leading code
[left-Ctrl + left-Ctrl + E] followed by one or two more keystrokes.
The built-in buzzer generates either a high-pitched beep for a correct hotkey
command or one short and one long beep for a bad command. The bad key
command won’t be sent to the selected computer.
Mask Hotkey Switch
The hotkey commands differ depending on the model. Errors or unpredictable
results might occur between the Extender Unit and mixed KVM switch types that
connect to each other. A shortcut for cascade hotkey configuration, the Mask
Hotkey Switch, allows users to bypass the Extender Unit and directly apply the
cascaded KVM switch’s built-in hotkey commands on the Extender Unit. This fea-
ture will be described in more detail in Section 4.3.1.
Alternate Hotkey Approach
You can press the front-panel push button and one keystroke as an alternate
hotkey for a specific hotkey feature set to the user’s preference. The KVM
extender can not conduct any hotkey controls when its hotkey function is masked
(Hotkey Mask Switch “ON”); this alternate approach is especially useful in this
state. See Section 4.3.2 for more information.
