seconds, the LED will blink red. When the LED turns green, the device is ready to
use.

4.2 Menu Settings

To enter the menu, press the ScrollLock key on the attached keyboard five times
quickly.

The on-screen display (OSD) menu appears on the attached display (see Figure 4-1).
You can access sub-menus by pressing the appropriate key. The currently installed
firmware version is displayed below the menu.

4. 2.1. Menu Item “U” — Update Flash FW

This option is used to update the firmware. Download the latest version of the
firmware from blackbox.com. Go to blackbox.com, type in the part number
"ACX300", and navigate to the proper device. Once on the product page of the
device you need firmware for, click on the "Resources" tab to view all available
firmware. Each update includes a detailed description of the update process.

4.2.2 Menu Item “M” – Option Overview

This option displays the extender’s activated options. The status is indicated by the
colors green (activated), and red (not activated).

If the memory option on the extender is activated, this can be enabled or disabled
at any point in this menu.

724-746-5500 | blackbox.com Page 19

Figure 4-1. OSD menu.

Chapter 4: Operation

Figure 4-2. Options Overview menu.

The menu displays the device ID.

1. Contact Black Box Technical Support at 724-746-5500 or [e-mail] to

get the activation code for the option you want to use. Compile a list of all
Request Keys/Device IDs from each ACX300 Receiver unit. The request key/
device ID is found in the Option Overview menu (M). Once you have the list of
request keys/device IDs, determine which license you need (switching:
ACX300-SW/storage devices: ACX300-U2). Once you have determined which
license you need, contact Black Box at 724-746-5500, or send an email to
[e-mail]. Include all of the Request Keys, Device IDs, and the license
you would like to purchase so that the proper activation codes can be generated.

2. Enter this activation code by pressing the “M” key. This will not alter options that

have already been activated.

3. Press “Esc” to return to the main menu.

4.2.3 Menu Item “D” – DDC Option

In this menu, you can define the DDC information used by the PC.

RS-232) take you to more menus, while the other four toggle on and off when you
press the marked key.

Figure 4-4. Extender Settings menu.

724-746-5500 | blackbox.com Page 21

Chapter 4: Operation

Menu Item “S” – Show Last Image

When this option is enabled, the console extender will not show a black screen
when it is no longer connected to a PC extender. Instead it will keep the last image
that it received. To indicate that this image is no longer current, the edges of the
screen will flash red.

Menu Item “I” – Monitor Sync

You can turn the monitor synchronization on or off. When enabled, the refresh rate
of the graphics card of the PC and that of the remote monitor are adjusted to match
one another. This ensures smooth transmission when the screen content changes
rapidly (e.g, when using multimedia applications).

Not all monitors support this method, so by default this option is disabled. If the
monitor starts to flicker, then it does not support this feature and should be disabled
again.

Menu Item “L” – Lock Menu

You can lock the extender OSD menu from this menu. When enabled, access to the
menu will be locked 5 minutes after start up. This prevents unauthorized access to
the extender menu. To enter the main menu again, restart the extender (turn the
power supply off and on).

Figure 4-5. Lock menu.

To enable or disable the menu from this screen, by press “0“ or “1“ respectively. To
return to the main menu, press “ESC.“

Page 22

724-746-5500 | blackbox.com

Chapter 4: Operation

Menu Item “P” – Power Save

When in power saving mode, the remote extender will turn its video off when it
receives no video for more than a minute. This enables the monitor to enter sleep
mode if supported. To wake, press any key on keyboard.

Menu Item “N” – Noise Filter

This feature improves video performance in very specific circumstances: when
viewing moving video with very high levels of noise (particularly along the horizontal
axis) then the frame rate of the extender will drop below a critical level, and artifacts
may begin appearing in the image.

When this feature is enabled, a filter will be activated whenever the frame rate falls
below the critical frame rate, and deactivated once the frame rate is sufficiently
high. This filter applies a blur to the image to reduce the noise, enabling the frame
rate to rise above the critical level.

We recommend enabling monitor synchronization when using this feature with a
compatible monitor.

4.2.6 Menu Item “K” — Keyboard Locale

Select between layouts for navigating the OSD. Choose from French (Azerty),
English (Qwerty), and German (Qwertz).

4.2.7 Menu Item “Q”

To close the extender menu, press the “Q” key.

724-746-5500 | blackbox.com Page 23

Each console starts disconnected and displays the log in screen. The switching menu
and switching hot keys are not available. The admin must configure each user to
have a specific PC bound to them. When a user logs on they will be automatically
connected to their bound PC. If another user wishes to use the console, the first
user must disconnect and logout with the key combination Ctrl-Alt-F11.

724-746-5500 | blackbox.com Page 25

Chapter 5: Switching Menu Guide/Settings

The rights control access to the Network Settings menu (only ADMIN), and which
users may interrupt the connection of which other users.

Admin: May interrupt connections of Masters and Users. If an Admin interrupts the
connection of another Admin, the interrupted Admin can reclaim the original
connection. Private connections can’t be interrupted.

Master: May interrupt connections of Users. If a Master interrupts the connection of
another Master, the interrupted Master can reclaim the original connection. Admins
and private connections can’t be interrupted.

User: If a User interrupts the connection of another User, the interrupted User may
reclaim the original connection. Admins, Masters ,and private connections can’t be
interrupted.

Groups: Each user can join up to 8 user groups. Each computer is defined as
belonging to one user group. By default, all computers are in the same user group.
This system makes it possible to allow or deny different users access to a computer.
The user’s group access is set by pressing the buttons 1–8.

5.8.5 Master View Item “H” – Multi-Head Config

If you use multiple monitors with a PC, then you can group individual local and
remote extenders together with the Multi-Head settings, making them switch as a
single unit.

To simplify the following steps, we recommend that you first name every extender
via the PC Extender List and Console Extender List menu items. To help identify the
extenders, when in these menus, the selected extender will start blinking red-green.

We recommend that, before performing the final installation, you first bring all the
extenders to a single location, connect them all to a single switch, and configure the
network.

This configuration setup requires a monitor, a keyboard, and a network switch.

listed as “conn’d”.

(Remote Extender). The status is listed as “in use.”

Green indicates a computer in the switching network that isn’t connected to any
workstation (Remote Extender). The status is listed as “free."

Red indicates a computer that was once in the switching network but isn’t currently
available. This usually indicates that the Extender has been disconnected from the
network. In this case, you can remove the computer from the switching menu with
the “delete” key.
