Introduction
Thank your for choosing the Black Box®ServSwitch MultiVideo™.
The ServSwitch MultiVideo represents the latest technology in single user
KVM switching for CPUs with multi-video outputs. The ServSwitch
MultiVideo is the result of our commitment to providing state-of-the-art
switching solutions for today’s demanding workplace. The ServSwitch
MultiVideo has proven to be a valuable and dependable investment for
users that have the need to switch multiple video images from 2, 4, or 8
computers.
There are several modelsavailable. The SW0xxxA series supports PC/Unix
systems and the KV0xxxA series supports PC, Apple, Sun, and Unix
systems.
Switching to a connected computer can be done by simple keyboard
commands, selecting the computer from the front panel, or through the
RS/232 port.
All ServSwitch MultiVideomodels can easily be expanded by chaining the
units together and configuring the system. Using the 2 port chassis, you
can expand the system to 4 computers. The 4 port chassis can expand to
16 computers, and the 8 port chassis can expand to 64 computers.
Before performing any installation or configuration, please refer to the
safety section of this manual.

System overview
The ServSwitch MultiVideo is designed to provide seamless, trouble-free
switching from a single KVM station to any connected computer. You can
switch to any of the connected computers by simple keyboard commands,
the front panel –or + buttons, or from a computer terminal or standalone
PC connected to the RS/232 serial port (not connected to a CPU port).
If your system demands are greater than a single unit can provide, the
ServSwitch MultiVideo can be easily expanded to connect up to 64
computers by chaining units together with expansion cables.
KVM station
A KVM station consisting of a keyboard, monitors, and mouse connects to
the rear panel DB25F connector labeled KVM1.
CPU connection
All CPU connectors on the ServSwitch MultiVideo are DB25F. The CPUs
are connected using a CPU cable designed to interface with the CPU
keyboard, mouse, and monitor ports. A CPU cable is needed for each
connected computer.
VIDEO connection
Video’s 2-4 are DB25F connectors. A DB25 to HD15 cable is needed for
each video output from a CPU.

Cables
(See Appendix B for cable part numbers)
ServSwitch MultiVideo to KVM station cables
The KVM cable connects a keyboard, video monitor, and mouse to the
ServSwitch MultiVideo. The KVM cable is configured with a DB25M
connector on one end and a connector for the keyboard, video, and mouse
cables on the other end. These KVM cable connectors should be
compatible with the types of connectors that are on your KVM stations
keyboard, monitor, and mouse cables.
ServSwitch MultiVideo to CPU cables
A CPU cable is used to connect each computer to the ServSwitch
MultiVideo. The CPU cable connects from the DB25F CPU ports on the
ServSwitch MultiVideo to the keyboard, video, and mouse ports on each
CPU. This cable is configured with a DB25M connector on one end and a
connector for the keyboard, video, and mouse on the other end. These
CPU cable connectors should be compatible with each CPUs keyboard,
video, and mouse port.
ServSwitch MultiVideo Master to Slave unit cables
In systems needing access to additional CPUs, the ServSwitch MultiVideo
can be cascaded to other units. To cascade a ServSwitch MultiVideo to
other “Slave” units, you will need one DB25M to DB25M, switch-to-switch
cable for each expansion unit.

Keyboard command usage
When using keyboard commands to enter information to the ServSwitch
MultiVideo, please observe the following guidelines to avoid entering
incorrect values or no values.
1. All commands start with a press and release of the left control key.
2. Commands following the press and release of the left control key must
be entered within 2 seconds or the command is aborted and the
additional keystrokes will be sent to the selected computer and not the
ServSwitchMultiVideo.
3. Use only the numeric keys above the keyboard and not the numeric
keypad.
4. Letter commands such as <Ctrl> M are not case sensitive and are only
shown in uppercase for clarity. Do not use the shift key to enter letter
commands.
5. To connect to the previous or next computer, the keyboard command is
<Ctrl> -or <Ctrl> +. The plus and minus keys on the keypad will
connect to the next or previous computer. The -and + keys on the
keyboard, next to the backspace key vary from country to country as to
their usage. These keys can still be used to connect to the next or
previous computer.

Configuration Menus

Main configuration menu
Figure 3. Main Menu
The ServSwitch MultiVideo uses a special command to establish
communication to the Unit and not a CPU. This command input is a press
and release of the left control <Ctrl> key, then the command. The
command must be entered within 2 seconds of pressing and releasing the
left control key or the ServSwitch MultiVideo re-establishes communication
with the connected CPU.
The main configuration menu is accessed from the keyboard by pressing
and releasing the left control <Ctrl> key and within 2 seconds pressing the
F12 key. The main configuration menu will display on the KVM monitor.
From this menu, you can configure the system, configure the connected
computers, the appearance or overlay of the displayed menus, and assign
unique passwords for accessing the configuration menus and a password
for accessing the connected computers. Use the up/down arrow keys to
select which section menu to configure and press enter.

Expansion
If your system consists of cascaded units, the expansion section of the
Configure System menu must be properly configured to provide the needed
information to manage the slave units.
It is recommended that all slave units have the same number of CPU ports.
To change the “Maximum computers”, “Expansion width”, and “Expansion
units”, use the up/down arrow keys and select the item and press enter. An
input box will display for a new value.
Maximum computers
This setting configures the total number of computers that are connected
and provides a wrap around value for scanning and the plus/minus
commands. Switching commands are validated against this value for a
valid port number. The “Maximum computers” value is the Expansion width
value times the number of slave units plus the CPU ports on the master unit
that are not used for expansion. Enter the number of connected computers
and press enter. Valid entries are 2 to 256.
Expansion width
The “Expansion width” setting determines how many computers are
connected to a slave unit. If the slave units are 4 port units, the width value
would be 4. If they are 8 port units, the expansion width value would be 8. If
the expansion units are a mixture of 4, 8, and/or 16 port units, the
“Expansion width” value is the number of CPU ports on the expansion unit
with the greatest number of ports.
Expansion units
The “Expansion units” setting is the number of slave units that are
connected to the master unit. This value determines which computer
number is associated with which physical connector.
If no expansion units are used, this number should be set to zero.
Scan settings
The scan settings section determines the amount of time in seconds that a
computer’s video is displayed before automatically switching to the next
sequential computer. The scan mode can be turned on or off and set to
automatically scan the computers when the ServSwitch MultiVideo is
powered up.
Scan time (seconds)
To change the scan time, highlight “Scan time” and press enter. An input
box will display for a new value. Enter the new scan time in seconds and
press enter. Valid entries are 1 to 999.

SERVSWITCH MULTIVIDEO INSTALLATION AND OPERATIONS MANUAL 13
Scan mode
This value turns scanning on or off. To change this value, select “Scan
mode” and press enter. An input box will appear. Select “On” or “Off” and
hit enter.
Power on scan
Setting this value to “On” will enable scanning when the ServSwitch
MultiVideo is powered on. To change this value, select “Power on scan”
and hit enter. Use the up/down arrow keys to select “OFF” or “ON” and
press enter.
Keyboard settings
The keyboard setting section of the configure system menu is used to
change the typematic rate and delay for PC keyboards and also to set the
language type for Sun keyboards.
Rate (keys/sec)
To change the rate value, highlight “Rate (keys/sec)” and press enter. An
input box will appear. Choose the rate value from table 5 that represents
the Rate keys/sec needed and press enter.
Delay
This setting is for PC keyboards only. It is used to adjust how long, after a
key is depressed and held, that key starts to repeat. To change the delay
value, select “Delay” and press enter. A list box will display showing the
choices available. Use the up/down arrow keys to select the delay rate
wanted and press enter.
