User Precautions

The manufacturer has the right to modify and alter the information, documentation and specifications
contained in this manual without prior notice. Manufactures makes no warranty, express, implied or statutory,
disclaims or specifically disclaims its possibility of sale and applicability for a particular purpose. The same
applies to any sold and authorized manufacturer's software described in this manual. If the Software Program
is found to be defective after purchase, the purchaser (and any non-manufacturer, its distributor or its
purchaser) will be responsible for all necessary service, repair and any incidental or consequential damages
resulting from the Software defect. The manufacturer is not responsible for any unauthorized interference

Please be sure that the voltage has been set correctly before use.

A typical LCD (liquid crystal display) has millions of pixels. A dead pixel is a defective pixel that does not display
the correct color. On the screen, it usually looks like a tiny black or white dot, which can also be any other
color. In the manufacturing process, even if a pixel on the tiny dust particles, or in the course of a slight impact
during transport, may have a dead pixel. In the ISO 13406-2 specification, four categories of acceptable screen
dead pixels are defined: the first is the best product, and the fourth is the worst. Almost all manufacturers use
the second level as a guarantee of the product, allowing a certain number of dead pixels exist, such as more
than the tolerance will change the screen. Since the manufacturer is of the opinion that this screen is
permitted by the ISO specification, we are not responsible for the replacement or warranty of the TFT LCD
panel.

USB expansion port, you can easily add an external USB mouse operation. It support two-level cascade,
enable a Single console to manage up to 256 computers.

In addition, according to the needs of users to expand the function, to KVM OVER IP transmission control
mode, only need to add the product in the expansion card slot IP KVM module card (DS-51000-1), you can
upgrade to remote network management digital KVM management device, user-friendly environment
does not change the existing circumstances quickly and quickly upgrade the advanced control mode
applications.

There are four convenient ways to switch the computer in the installation: (1) Use the Port Select button
on the front panel of the switch; (2) Enter the hotkey combination from the keyboard; (3) From the
On-Screen Display (OSD) select. The auto-scan feature provides automatic scanning and monitors the
computers in the installation architecture one by one. (4) Through the expansion of the IP module of the
network port for remote network control operation.

This product is very fast and easy to install, just simply connect the cable to the appropriate connection
Port, no software settings, no cumbersome installation procedures, and there will be no incompatibility
issues. As the device can directly access the keyboard input data, it can operate in a variety of operating
platforms (compatible PC, Mac, Sun, etc.).

As it allows a single console to manage the many computers, a set of KVM installations,(1) eliminates the
cost of individual keyboards, monitors, and mice for each computer; and (2) saves the cost of additional
equipment that can be used by the additional devices. This allows for the installation of a set of KVMs that
can be managed from a single console space; (3) to save energy costs; (4) to avoid moving back and forth
between the various computers inconvenience and waste. (5) The rapid upgrade to IP control mode
