Introduction
Overview
The ATEN CL3884NW LCD KVM Switch offers a space-saving, streamlined
approach to KVM switch technology by integrating a keyboard, 18.5" LEDbacklit 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 LC D monitor ro tates 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.

Port ID Numbering & Port Selection
Port ID Numbering
Port ID number: This number is assigned according to the port that the
computer is connected to on the rear of the CL3884NW. For example, a
computer connected to port 1 is assigned port ID 1.
Device name: By default, the computer connected to port 1 is named PC 1, the
computer connected to port 2 is named PC 2, and so forth. To change the device
name, go to System Settings > Port Configuration, see Port Configuration,
page 57 for details.
Port Selection
You can directly access any computer on any level of the installation by
specifying the Port ID that the computer is connected to.
Using the CPU Selection Pushbuttons (see CPU Port Selection
Pushbutton / LEDs, page 6).
Using the OSD (see OSD Operation, page 47).
Using the Hotkey Port Selection method (see Keyboard Port Operation,
page 63).
Using the RS-232 Commands (see RS-232 Operation, page 75).
If you connect a KVM switch (CM1164A / CM1284) to the CL3884NW, Port
ID numbering and Port Selection follow the method used by the connected
KVM switch. Consult your KVM switch’s user manual for details.
Note: In a cascade setup, a port ID number of “1-3” indicates that the video
source comes from the third port of the secondary CM1164A / CM1284
connected to port 1 of the primary CL3884NW.

All hotkey operations begin by invoking the Hotkey mode. There are three
methods to invoke the Hotkey mode: Dedicated Invocation Key – by pressing
the dedicated invocation key on the keyboard module, and two Keystroke
Sequences – by entering the correct keystroke sequence, though only one can
be operational at any given time.
Note: Make sure that the Hotkey Command Mode function is enabled and that
you key in the appropriate Hotkey. See page 68 for details.
Dedicated Invocation Key
A dedicated key is provided on the keyboard module to make it easy to invoke
the Hotkey Mode (as shown in the diagram below):

Select the Active Port
Each KVM port is assigned a port ID (see Port ID Numbering, page 40). You
can directly access any computer on the installation with a hotkey combination
that specifies the port ID of the KVM port that a computer is connected to. To
access a computer using hotkeys:
1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12]
combination.
2. Key in the port ID.
The port ID numbers display on the command line as you key them in. If
you make a mistake, use [Backspace] to erase the wrong number.
3. Press [Enter].
After you press [Enter], the KVM focus switches to the designated
computer and you automatically exit hotkey mode.
Note: In hotkey mode, KVM focus will not switch to a port if an invalid
switch or port number is entered. The hotkey command line will
continue to display on the screen until you enter a valid switch and port
number combination, or exit hotkey mode.

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.
