INTRODUCTION
The XTENDEX Series CAT5 Extender (XTENDEX) is designed to enable one CPU to be controlled by two users, one local and
one remote. Extended components may include a standard monitor (or touchscreen monitor when RS232 is supported), PS/2
keyboard, and PS/2 mouse. The remote user can be located as much as 1000 feet away from a PS/2 CPU via Category 5/5e/6
unshielded twisted-pair cable. The local user will be located near the CPU.
The XTENDEX Series Extender is extremely simple to install and has been thoroughly tested to insure reliable performance.
Through the use of Category 5 cable it is possible to economically increase the flexibility of a computer system. Here are some of
the features and ways this can benefit any workplace:
Allows the placement of computer peripherals (monitor, keyboard, and mouse) in a location where
only these parts are needed without having the CPU there too, taking up valuable space
Allows a PS/2 CPU to be accessed by both a local and remote user (up to 1000 feet away)
Compatible with XGA, VGA, and SVGA systems
Provides crisp and clear resolution up to 1920 x 1200 @ 1000 feet (see page 13 for more details)
Compatible with all NTI switches and splitters, enabling the joining of products to create a system that
satisfies all networking needs
Video quality adjustment, for varying lengths of cable, is automatic (see page 11) providing optimum image quality
Built-in surge protection

LIMITATIONS
Hot-plugging of devices is supported provided devices were originally connected at power-up.
In order for two users to share a PS/2 CPU, the user in control must pause for at least 3 seconds before another user can
take control. After the 3 second pause, either user can take control of the CPU.
For model with RS232 support:
The RS232 ports on the Local and Remote Units will support serial devices other than touchscreen monitors as follows:
2 simple devices (i.e. mice) connected to each unit, or
1 complex device (i.e. serial modem, RS232 command port on an NTI switch) connected to
either the Remote or Local Unit.
The RS232 port supports all baud rates up to 57.6K bits per second and the attached CPU must be configured accordingly.
PREPARATION FOR INSTALLATION
Locations should be chosen for the monitors, mice, and keyboards that also have space to connect the Remote and Local
Units within the distance provided by the cables. If extension cables are needed, contact NTI for the cables required.
The CAT5 cables must be run to the locations where the Remote and Local Units will be connected. Be careful to route the
cables away from any sources of magnetic fields or electrical interference that might reduce the quality of the video signal
(i.e. AC motors, welding equipment, etc.).
All cables should be installed in such a way that they do not cause stress on their connections to the equipment. Extended
lengths of cable hanging from a connection may interfere with the quality of that connection. Secure cables as needed to
minimize this.
Properly shut down and disconnect the power from the CPU and monitors to be separated. If other equipment is involved
whose connections are being interrupted, be sure to refer to the instruction manuals for that equipment for proper
disconnection and re-connection procedures before proceeding.
Note: CAT5 connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series products
should not be run underground, outdoors or between buildings.
WARNING: Outdoor or underground runs of CAT5 cable could be dangerous and will void the warranty.
WARNING: The CATx connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series
products must be wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc.) The use of a CROSSOVER CABLE will
damage the extender and void your warranty.

VIDEO ADJUSTMENTS
Automatic Video Quality Adjustment
Video quality is broken down into “general video quality” for brightness and sharpness of the images, and “color skew” for how the
colors align with each other on the monitor. Both general video quality and color skew adjustments are done automatically. The
automatic video adjustments are calibrated for unshielded twisted pair cable. For shielded cable fine adjustment may be
necessary and this can be done from keyboard keys using Command Mode. Video Quality Adjustment settings are automatically
stored in the XTENDEX. Settings will be restored each time the XTENDEX is powered-ON. Test patterns for color skew
adjustment are provided (see link below).
Note: If the cable is changed after making manual video adjustments, the XTENDEX will restore these settings to factory
default and fine adjustments with the new cable may be necessary.
Test Patterns for Color Skew Adjustment
To verify the need for and effect of color skew adjustment using a test pattern specifically designed for your
display setting, go to http://www.networktechinc.com/usbkvm.html#tab-5 and click on the “test-pattern-
nXm.pdf” file that matches your current video resolution. Follow the instructions below to make
adjustments as needed.
Fine Video Quality Adjustment
These extenders are enabled with a Command Mode feature to perform the following:
fine adjustment of the general video quality
fine adjustment of color skew (alignment of red, green, and blue signals on the monitor)
update DDC information between the monitor(s) and CPU
Most of the video quality adjustment is automatic at power ON, but if some adjustment is necessary, this can be done using only
the keyboard attached to the Remote Unit.
Enter Command Mode
The user can enter Command Mode using any of three different methods;
Method 1
1. Press and hold the left <Shift> key
2. Press the right <Shift> key
3. Release both keys
Method 2
Press and release the <Scroll Lock> key twice fast (press twice within 1 second)
Method 3
Press and release the left <Shift> key twice fast, then press and release the <Esc> key once , all within 2
seconds
The three keyboard LEDs (NumLock, CapsLock, and ScrollLock) will blink at the same time to indicate entrance into Command
Mode.
General Video Quality Adjustment
Command Mode opens into General Video Quality Adjustment mode. To fine tune the general video quality, press the <Left
Arrow> or <Right Arrow> keys until the desired improvement in the display has been achieved.
Color Skew Adjustment
If a specific color appears to be skewed and is in need of fine adjustment, the user can switch to Red, Green, or Blue Skew
Adjustment mode by pressing <R>, <G> or <B> respectively. The keyboard LEDs will identify the mode as indicated in the table on
page 14. Press the < Left Arrow> or <Right Arrow> keys until the desired improvement in the color alignment has been
achieved. Press <V> to return to General Video Quality Adjustment mode.

General Video Quality Blink Blink Blink
Red Skew Blink Solid Solid
Green Skew Solid Blink Solid
Blue Skew Solid Solid Blink
DDC OFF Solid OFF
Reset Defaults
Press the<A> key (while in Command Mode) to reset the fine tuning to default settings. Once settings have been reset, the user
will automatically return to General Video Quality Adjustment mode.
Exit Command Mode
Press the <Esc> key to exit Command Mode and return to normal operation. All keyboard LEDs will return to current keyboard
LED state.
FYI: Video quality will be limited by several factors. Some factors include the quality and type of CAT5 cable being
used, the length of cable run, the quality of the monitor, the resolution setting of the monitor, and the quality of the video
card used in the video source. If the desired level of image clarity cannot be achieved by making the adjustments
described in this section, consider the following possible adjustments that can be made:
Improve the quality of cable used -CAT5,5e,or 6 (CAT5e unshielded (UTP) cable will provide the best
performance)
Use unshielded cable (UTP) instead of shielded cable (STP)
Shorten the length of the cable between the remote and local
Reduce the resolution setting on the monitor used
Use a higher quality video card in the video source
