PREPARATION FOR INSTALLATION

• A location should be chosen for the monitor, mouse, and keyboard that also has space to mount the Remote Unit within the
distance provided by the cables from the monitor, mouse, and keyboard. If extension cables are needed, contact NTI for the
cables required. If a local user will be connected, a proper location must be chosen for these devices too.

• The CAT5 cable(s) must be run to the locations where the Remote and Local Units will be placed. 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.). NOTE: If CAT5 cable is already installed in the wall and there are RJ45 wall
outlets, it will be necessary to obtain male-to-male straight through connection cables long enough to reach from the wall
outlets to the mounting locations of the Remote and Local Units.

• A properly grounded, polarized, and preferably surge-protected 120V or 240V electrical outlet (de pending on the AC adapter
being used) must be installed close enough to the mounting location of the Remote Unit and monitor to plug them into.

• All cables should be installed in a fashion that will avoid 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 ne eded to prevent this.

• Properly shut down and disconnect the power of the CPU and monitor. Disconnect the monitor, keyboard, and mouse. 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 proce eding.

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.

Adjust Brightness

The brightness of the extended image can be increased or decreased by pressing the <Up Arrow> or <Down Arrow>
(respectively) while in Command Mode. This adjustment is in addition to any adjustments made possible by controls on your
monitor.

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 any
time the XTENDEX is powered ON or if the CATx cable is disconnected and then reconnected. T hese adjustments can also be
forced by pressing the <A> key while in Command Mode.

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 on the CD.

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.

10

Fine Video Quality Adjustment

General Video Quality Adjustment

Command Mode opens into General Video Quality Adjustment mode. To fine tune the general video qualit y, 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
below. 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.

Test Patterns

To verify the need for and effect of color skew adjustment using a test pattern specifically designed for your display setting,
browse the CD this manual was found on and click on the “test-pattern-nXm.pdf” file that matches your current video resolution.
Follow the instructions above to make adjustments as needed.

Note: For additional quality adjustment, it may be necessary to adjust the brightness and con trast settings of the
monitor.

Update DDC

DDC information allows the CPU to automatically select the optimal resolution for your monitor. The procedure to u pdate DDC
information (below) must be performed only once at initial setup through Command Mode (provided the monitor is not changed).
Both the Local and Remote Units must be powered in order to update the DDC information. The DDC information will be based
on the monitor connected to the Remote Unit.

To update DDC information (from Command Mode);

1. press <D> to enter DDC Update mode. (See chart above for LED indications.)

2. press the < Left Arrow> + <Right Arrow> keys simultaneously to cause DDC information to be updated

When the update is complete (less than one second), the three keyboard LEDs will blink at the same time.

3. press <V> to return to General Video Quality Adjustment mode.

4. press <Esc> to exit Command Mode

5. Restart the CPU.

Note: It is recommended that the monitors connected to the Remote and Local units be of the same make and model.

Attention: Some graphics cards will not send a video signal to the monitor until it has received the DDC information from the

monitor. In this case, the monitor may not display anything until the DDC information is read. This may occur if this is the first
time the monitor is being connected to the XTENDEX. The DDC information must be updated in the XTENDEX to achieve video
using the procedure outlined above.

If the monitor is changed to a different model than was initially installed, the update procedure must be repeated through
Command Mode.

11

Toggle MAC Mode

MAC Mode enables the user to connect the Local Unit to a MAC CPU. MAC Mode configures the Local Unit for passing mouse
information to the MAC CPU. This is useful when the user wants to use mouse drivers provided by the mouse vendor, which
allows the use of programmable functions for each mouse button. The Local Unit can be configured whenever n ecessary.

In the default setting (non-MAC Mode), the XTENDEX is configured for connection to a SUN or Windo ws CPU. To toggle
between non-MAC Mode and MAC Mode, press <M> while in Command Mode. The “MAC Mode” LED on the Remote Unit will
illuminate when the XTENDEX is in MAC Mode.

NOTE: When the port is connected to a PC or SUN CPU, MAC Mode (and the MAC Mode LED) should be OFF.

To do this;

1. Enter Command Mode. (Simultaneousl y pr ess the left and right <Shift> keys on the keyboard connected to the Remote

Unit. The keyboard LEDs will illuminate. )

2. If a MAC CPU is connected, press the <M> key. The keyboard LEDs will momentarily flash and the “MAC” LED on the

Remote Unit will illuminate to indicate MAC Mode is ON. (See Error! Reference source not found.)

To reconnect the XTENDEX to a SUN or Windows CPU (the default setting) , press the <W> key and the “MAC” LED will go OFF.

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

FIRMWARE UPGRADE PROCEDURE

This procedure describes how to upgrade the firmware in this XTENDEX. Only models with Additional USB Support can be
upgraded. If you are not certain whether this XTENDEX has the most up-to-date firmware available, simply download the latest
version and follow the upgrade procedure. All versions of firmware can be downloaded from

http://www.networktechinc.com/usbkvm.html

The XTENDEX has 3 types of micro-controllers:

1. Local Controller – the Local Controller will be upgraded with a binary file named c5usbvu-lcsx-x.bin. (where x-x is the rev
number)

2. Local Port Controller – the Loc al Port Controller will be upgraded with a hex file named c5usbvu-lcpx-x.hex.

3. Remote Controller – the Remote Controller will be upgraded with a bin file named uc5usbvu-rcsx-x.bin.

The XTENDEX firmware has a bootloader which can be used for firmware upgrades. T he bootloader resides in a protected ar ea
of Flash memory, so that if the upgrade fails for any r eason, the bootloader will still be available to be used to r e-program the
entire unit.

Upgrades are made to the Local Controller, Loca l Port Controller, or Remote Controller separately. Not all Controller firmware is
updated with each revision, however it is highly recommended that if you upgrade one piece of firmware, you upgrade each
controller segment to make sure your Local and Remote are both at current versions.

.

Requirements

¾ CAT5 Patch Cable (supplied with XTENDEX)
¾ RJ45-DB9 or DB25 Adapter (supplied with XTENDEX)
¾ Computer with a Terminal Console (for example, HyperTerminal in Windows, or any similar program able to send files using

Xmodem protocol)

¾ Firmware files for the XTENDEX on the computer with the Terminal Console.
