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.

up, down, left, or right– off one screen and onto another to switch keyboard/

mouse control to the adjacent computer. The audio and USB hub focus is also

switched to the new computer. The mouse cursor can also move across displays

even when they are cascaded.

Before using the Boundless Switching, the users must turn off mouse

acceleration in the operation system. The Boundless Switching can only work

with either the touch pad or the USB mouse connected to the second console.

The default setting is touch pad, you can toggle between the two to perform the

boundless switching, see Hotkey Summary Table, page 68 for details.

To change the keys for invoking the HSM, see HSM, page 54.

Pressing [Esc] exits Hotkey mode.

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.

Chapter 5. Keyboard Port Operation

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.
