Introduction
Overview
The AcroGear series, fully compatible with USB specification, are the
combination of USB KVM (keyboard/Video/mouse) switch and USB
peripherals sharing device. You can easily operate up to 4 PCs, G3/G4 Macs,
or Mac Pros respectively from 1 USB keyboard, 1 USB mouse, and 1 DVI
monitor saving you space, time, equipment and money. Its peripheral sharing
function enables you to share more USB peripherals among all computers.
The “FUNC” button for selecting the audio and adjusting the video signal
strength. Yet, the AcroGear series support the audio function (Speaker + MIC)
as well. Users can switch among four media sources and enjoy the output on

System Requirements
Console side
One / Two DVI monitor (Two for dual display type)
One USB Keyboard
One USB mouse
Computer side
Each USB-enabled computer must be connected to the DAAG-114 /
DADG-124 by
One DVI cable for monitor, as shown below
One USB A-B cable with Type-A and Type-B plug for USB devices, as
shown below

Installation
PC BIOS Notice
The following BIOS setup changes are necessary for PC users and not
necessary for Mac users:
1. In STANDARD CMOS, set HALT ON ERROR to ALL BUT KEYBOARD.
2. In PNP AND PCI SETUP, set PNP OS INSTALLED to YES and set USB
IRQ to ENABLED.
Note: The AcroGear series are applicable for USB keyboard and mouse
switching from one computer to the other. If you plan to share other
peripherals such as a CCD camera, printer or scanner, it is required to
shut down the driver of the computer before switching to another
computer. Because port switching is equivalent to unplugging the
USB cable from one computer and plugging it to another one, some USB
drivers check attached USB peripherals all the time and do not accept
plug-n-play function.

Console Connection
Before installation, make sure all devices and computers to be connected to
the unit have been turned off.
Plug a monitor to the Console's DVI port; plug a USB keyboard and a USB
mouse to any two of the Console's USB ports as shown below.

Computer Connection
Use a male-to-male cable to connect from a computer's DVI port to DAAG-114
/ DADG-124 DVI port of PC side.
Use a USB A-B Cable to connect from the DAAG-114 / DADG-124 USB port (B
connector, square connector) to the USB port on the corresponding computer
(A connector, flat connector), as shown below.

Operations
Front Panel
1. On-line LED & Selected LED
When the LED turns green, the connected computer is powered-on. When
a computer is selected, its corresponding red LED illuminates.
2. Pushbuttons
Each computer has a button associated with it on the front panel for
selection.

simultaneously. The port LED flashes during Auto Scan. Auto Scan is
effective for powered-on computers only. To exit the Auto Scan mode, just tap
any one of the pushbuttons.
Note: keyboard and mouse are not operable duri ng Auto Scan.
Scan Time
It sets the scan interval for Auto Scan. The Scan Time options are 3, 8, 15
and 30 seconds.
To change the Scan Time interval, press both front panel buttons "1" and "2"
simultaneously. The DAAG-114 / DADG-124 beep 1, 2, 3 or 4 times for Scan
Time of 3, 8, 15 or 30 seconds respectively.
Note: Scan Time is automatically set to the default of 3 seconds when the units
loses power.

Adjust the Video Signal
To adjust the optimal video signal strength corresponding to the length or
quality of DVI cable, the user can press “FUNC” button combining with the
other pushbuttons.
Step 1. Press “FUNC” button three times, the LED of
“FUNC” will flash one time per second.
Step 2.
Press pushbutton “1” one or two times for adjusting the equalization of
selected port input video strength with one beep (normal) or two beeps
(enhance) respectively.
or
Press pushbutton “3” one or two times for adjusting the output current of
selected port with one beep (normal) or two beeps (enhance)
respectively.

can press “FUNC” button combining with the other pushbuttons.
Step 1. Press and hold “FUNC” button. Either all of 4 green LEDs light up or
just one green LED lights up. All of 4 green LEDs light up means the
audio port and the selected computer port are the same; we call it as
“tracking mode”. On the other hand, just one green LED lights up (the
selected audio port) means the audio port is different from the
selected computer port; we call it as “non-tracking mode”.
Step 2.

Hotkey Commands
The Hot-key command is a short keyboard sequence to select a computer, to
activate computer scan, etc. KVM Switch interprets keystrokes for hot-keys
all the time. A hot-key sequence starts with two left Ctrl keystrokes ( in
0.2 seconds ) followed by one or two more keystrokes. A built-in buzzer
generates a high-pitch beep for correct hot-key command; otherwise, one
low-pitch beep for error and the bad key sequence will not be forwarded to the
selected computer.
NOTE: By pressing left Shift + Num Lock + Num Lock + left Ctrl users can
enable/ disable the hotkey commands.
To select a computer:
Left Ctrl + Left Ctrl + 1
Selects the computer at port 1.
Left Ctrl + Left Ctrl + 2
Selects the computer at port 2
Do not use the keypad at the right of the keyboard.
To start Auto Scan, automatically scan power- on computers one by one at a
fixed interval:
8
Left Ctrl + Left Ctrl + F1
To abort the Auto Scan mode, press the left Ctrl key twice. When Auto
Scan detects any keyboard or mouse activity, it suspends the scanning till
the activity stops; it then resumes with the next computer in sequence.
The length of the Auto Scan interval (Scan Rate) is adjustable, see below.
Manual Scan enables you to manually switch back and forth between
power-on
computers.
Left Ctrl + Left Ctrl + F2
Press Ï or Ð to select the previous or the next computer in sequence.
And, press any other key to abort the Manual Scan.
To adjust Scan Rate, this sets the duration before switching to the next
computer in Auto Scan:
