8-Port DVI USB Module
2. Overview
2.1 Introduction
The 8-Port DVI USB Module allows you to control up to eight servers or
computers with DVI monitors and USB keyboards and mice from a single
KVT517A-WIDE. The module is not designed to be used by itself. It functions in
the same way as a ServSwitch™does when used with a ServTray™.
Using the module is an efficient way to manage multiple computers in server
rooms where space is at a premium. The on-screen display (OSD) features
computer naming, computer selection, status indication, AutoScan, and more.
The module has one DVI connector and one USB for each computer connection.
Use the OSD interface, hotkeys, or ServTray buttons to control the KVM switch.
Navigate through the OSD menus using function keys (see Section 4.2 for details).
Using a hotkey command sequence (see Section 4.3 for details), you can control
the KVM switch. The module beeps to confirm that it’s in hotkey mode.
The AutoScan function enables you to automatically scan and monitor all
computers, one by one, that are connected to the module. And the module
works with most common Windows®operating systems.
The module supports video resolutions of up to 2048 x 1152.

Chapter 4: Operation
4. Operation
4.1 Powering Up the System
Once all cables have been connected and all computers have been powered on,
the module emulates mouse and keyboard signals on each port, allowing your
computer to boot normally. The module is now ready for use. You can configure
the module in two ways: by activating the On-Screen Display (OSD) window or by
typing hotkey commands.
4.2 Selecting Computers Using On-Screen Display (OSD)
The module can operate via an on-screen display (OSD). To use this option, press
the Left-Ctrl key twice within two seconds to see the hotkey menu (an OSD
option) if it is enabled. Press the Left-Ctrl key three times within two seconds, and
a ServSwitch menu screen appears showing a list of the computers with corre-
sponding port numbers, names, and statuses. See Figure 4-1.

In Figures 4-1 and 4-2, the color of a device name is green if it has power and is
ready for operation, or the color is white if it has no power. The OSD menu
updates the color when the device’s power is activated.
Press the up-arrow, down-arrow, or 1–8 keys to highlight a computer, then press
the Enter key to select it. Or, press Esc to exit OSD and remove the OSD menu
from the display. The status window then returns to the display and indicates the
currently selected computer or operating status.
An eyemark to the right of a name (see Figure 4-2) indicates that computer is
selected and monitored in Scan mode. In the OSD, this mark can be switched on
or off by pressing the F2 key.
Press the Esc key to exit OSD and to return to the port/PC screen that you were
previously connected to.
The Function and Escape keys work as follows:
The F1 key allows you to edit a computer or slave’s name entry with up to 14
characters. First highlight a port, then press F1 and type the name. Valid charac-
ters are A–Z, 0–9, and the dash character. If you type lowercase letters, they will
be converted to uppercase ones. Press the Backspace key to delete a letter one at
a time. Non-volatile memory stores all name entries until you change them, even
if the unit is powered down.
8-Port DVI USB Module
Page 14 724-746-5500 | blackbox.com

The F2 key allows you to switch a computer’s eyemark on or off. First, use the up-
arrow and down-arrow keys to highlight a computer, then press F2 to switch its
eyemark on or off. If Scan Type (described on the following page) is Ready PC +
eyemark, only the powered-on and eyemark-selected computers will be displayed
sequentially in Scan mode. If Scan Type is Eyemark only, only the eyemark-selected
computers will be displayed sequentially in Scan mode.
The F3 key enables you to lock a computer to prevent unauthorized access by
highlighting it and then pressing F3. Now, for the new password, type in up to
four characters (A–Z, 0–9, and “-”) and press the Enter key. A security-enabled
computer is marked with a lock symbol following its port number. To permanently
disable the security function from a locked computer, highlight it, press F3 and
then type in the password.
If you want to access the locked computer temporarily, simply highlight it and
press the Enter key (instead of the F3 key), then the OSD will ask you for the pass-
word. After typing in the correct password, you are allowed to use the computer.
This computer is automatically re-locked once you switch to another port. During
Scan mode, the OSD skips the password-protected computers.
The F4 key enables more functions, including AutoScan, Manual Scan, Scan Type,
Scan Rate, Hotkey Menu, CH Display, and Position. A new screen pops up display-
ing these functions as described on the next two pages. Most of them are
marked with a triangle, indicating there are options to choose from. Use the up-
arrow or down-arrow key to select the functions, and then press the Enter key.
Available options will be shown in the middle of the screen. Again, use the up-
arrow or down-arrow keys to view each option, and then press the Enter key to
select it.
Press the Esc key to exit the OSD at any time and return to the port/PC screen
that you were previously connected to.
AutoScan
In this mode, the module automatically switches from one powered-on computer
to the next one, sequentially in a fixed interval. During AutoScan mode, the OSD
displays the name of the selected computer. When AutoScan detects any key-
board or mouse activity, it suspends the scanning until activity stops; it then
resumes with the next computer in sequence. To abort the AutoScan mode, press
the left Ctrl key twice, or press any front-panel button. Scan Type and Scan Rate
set the scan pattern. Scan Type (press F4, then select More\Scan Type) determines
if scanned computers must also be eyemark selected. Scan Rate (press F4, then
select More\Scan Rate) sets the duration a computer is displayed before selecting
the next one.
