INTRODUCTION

The ST-C5USBV-300 USB Extender (XTENDEX) is designed to enable the relocation of a monitor, USB keyboard, and USB
mouse from a USB CPU or NTI USB KVM switch by as much as 300 feet via CAT5 cable in addition to having a monitor, USB
keyboard, and USB mouse connected locally. It is extremely simple to install and has been thoroughly tested to insure reliable
performance. Through the use of Category 5 shielded or unshielded twisted-pair cable (STP/UTP) or Category 6 unshielded
twisted-pair cable (UTP), it is possible to economically increase the flexibility of a computer system.

Options:

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.).
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 (depending 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 needed 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 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.

NOTE: If CAT5 cable is already installed in the wall and there are RJ45 wall

Plug-in and Boot Up

1. Plug the power cord(s) from the monitor(s) into power outlet(s).

2. Connect the AC adapter power connectors to the 9VDC ports on the Remote and Local Units. (AC adapter shown in Fig. 9)

3. Plug the AC adapters into power outlets. The “Power” LED (Green) on the CAT5 connector of each unit should illuminate,
indicating that a proper power connection has been made.

4. Turn ON the CPU and monitor(s). The CPU and monitor(s) should each react as if they were directly connected to each
other. The yellow communication LEDs on the Remote and Local Units (see Fig. 8) should blink indicating there is proper
communication between them.

Note: A loss of signal (blank screen) may be
experienced for an instant during the auto­compensation process after powering-up (ST­C5USBVA model only). This may also occur if the
XTENDEX senses a loss of or weak signal connection
in the CAT5 cable.

COMMAND MODE

The XTENDEX has two areas of user control that can be used as needed. The user can adjust video quality (described
below) , or enable/disable MAC mode (see page 11) These controls are accessed by entering Command Mode.

To enter Command Mode, simultaneously press the left and right <Shift> keys on the keyboard connected to the Remote
Unit. The keyboard LEDs will illuminate.

To exit Command Mode, press <Esc>.

Automatic Video Quality Adjustment (ST-C5USBVA-300 only)

Video quality adjustment is done automatically to assure the image is as clear as possible.

Note: If a different type of cable is used (i.e. shielded cable) and the image is not crisp and clear, there may be a need for
fine adjustment.. For fine adjustment, follow the same procedure as described under “Manual Video Quality Adjustment”
below.

Manual Video Quality Adjustment (ST-C5USBV-300 only)

It is possible that on initial startup the image on the monitor will not be as crisp as the image normally is. This is due to the

frequency characteristics of the CAT5 cable. It may be necessary to enter Command Mode (described above) and press
the ▲ (up arrow) or ▼(down arrow) keys on the remote keyboard until the image is crisp and clear.

• Press ▲ (up arrow) key if the image is not crisp and clear enough.

• Press the ▼(down arrow) key if the image has been over-corrected (such that horizontal lines appear to trail or

shadow at the edge of an open window).

• A momentary press of either key will make a minor change in the image.

Ultimately, the image quality should improve to a satisfactory level. Once the adjustment is made, it should not be necessary to
change it again, as the new settings are stored in memory and become the default settings with each startup. To exit Command
Mode, press <Esc>.

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

Note: The video quality adjustment procedure can only be performed from the keyboard connected to the Remote Unit.

14

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 necessary.

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

To do this;

1. Enter Command Mode. (Simultaneously press 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 Fig. 10)

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

go OFF.

Figure 16- MAC LED

After setting, the configuration is stored in memory and will be retrieved whenever the XTENDEX is powered ON.

Note: MAC Mode can only be enabled from the keyboard connected to the Remote Unit.

DDC SUPPORT

DDC information allows the CPU to automatically detect the video capability of your monitor. The DDC information is updated
automatically at initial power-ON of the ST-C5USBV-300 Extender or whenever a different monitor is connected to the Extender.
DDC is only supported for the monitor connected to the Local Extender and it is recommended that the monitor connected to the
remote be the same model. The Local Extender and the monitor must both be powered ON prior to the CPU in order to update
the DDC information.
