Introduction
Overview
The ATEN CL3884NW LCD KVM Switch offers a space-saving, streamlined
approach to KVM switch technology by integrating a keyboard, 18.5" LED-
backlit LCD monitor, and a touchpad in a 1U rack-mountable slide housing.
The dual rail design enables the LCD monitor, keyboard and touchpad to
operate independently of each other. To maximize space utilization, the
keyboard and touchpad modules can slide back to "hideaway" when not in use,
while the LCD monitor rotates back, flush against the rack, to allow convenient
monitoring of computer activity.
The CL3884NW offers dual console outputs that guarantees users real-time
monitoring functionality. You can control both outputs to display the following
display modes: Quad View, Picture in Picture (PiP), Picture by Picture (PbP),
and Picture on Picture (PoP). The display modes have different layout options
to allow you to customize which sources are being displayed. In addition, being
able to cascade up to 2 levels, the CL3884NW can reach up to a maximum of
16 video sources that can be simultaneously displayed and controlled with
independent keyboard and mouse.
Featuring Boundless Switching, the CL3884NW allows users to switch control
to another computer by simply moving the mouse cursor across a screen border
and onto the target computer display without limitations. With patented ATEN
technology – Video DynaSync™, users can enjoy better display resolutions
and faster switching between systems. What’s more, the EDID modes are
available for smooth power-up, high-quality display that eliminates monitor
compatibility issue.
For added convenience, users can choose to manage the computer from an
external console. The CL3884NW features a USB peripheral port on the unit’s
front panel, ports for the external KVM console (USB keyboard/mouse and
HDMI monitor) on the rear panel, and audio ports for connecting audio
speakers.
As a feature-rich LCD KVM Switch, the CL3884NW is aimed not just to
achieve but exceed the requirements for space utility optimization, superior
video quality, adaptive deployment, and operational versatility, and is
especially ideal for control rooms in any industry that seeks effective and
efficient use of space.

Auto Scan Mode
The Auto Scan feature automatically cycles the KVM focus through the
computer ports at regular intervals. This allows you to monitor the computer
activity without having to switch from port to port manually. Although the
video focus switches from port to port, the keyboard, mouse, and USB focus
do not switch. They stay with the port they were on when Auto Scanning
started.
While Auto Scan Mode is in effect, ordinary keyboard and mouse functions are
suspended – only Auto Scan Mode keystrokes and mouse clicks can be input.
You must exit Auto Scan Mode in order to regain normal control of the
console.
Auto Scanning - Display Modes
Auto scan can be invoked with Full Screen, PiP Dual, PiP Triple, PbP Dual,
and PbP Triple modes. When you start auto scan with PiP Dual or PiP Triple
one of the secondary windows (channels) is used to auto scan two or three
computers.
Auto Scan mode does not work with the Quad View, PiP Quad, or PoP mode
as these modes already display all computers on the screen. (see Display
Modes, page 34).
Invoking Auto Scan:
To start Auto Scan, key in the following Hotkey combination:
1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12]
combination.
2. Press [A]. After you press A, then [Enter], you automatically exit hotkey
mode, and enter Auto Scan mode.
While you are in Auto Scan mode, you can pause the scanning in order
to keep the focus on a particular computer either by pressing P or with
a left click of the mouse. During the time that auto-scanning is paused,
the command line displays: Auto Scan: Paused.
Pausing when you want to keep the focus on a particular computer is
more convenient than exiting Auto Scan mode because when you
resume scanning, you start from where you left off. If, on the other
hand, you exited and restarted, scanning would start over from the very
first computer on the installation.
