INTRODUCTION
The XTENDEX®DVI Extender via Fiber Optic Cable locates a single link digital DVI-D display up to 3,280 feet (1,000 meters)
from a computer using a single SC multimode (50-micron or 62.5-micron) fiber optic strand. Each extender consists of a
transmitter that connects to a computer and a receiver that connects to a monitor.
Complies with DVI 1.0 standards.
Signal transmission via one strand multimode (50-micron or 62.5-micron) SC fiber optic cable –no RF interference.
Small form factor –for easy connection and placement.
Cables can be installed in conduit prior to extender installation.
Built-in default EDID table can be programmed to support any DVI display device..
Low RFI/EMI for sensitive applications.
No software to install.
The DVI Optical Extender is the ideal solution for a wide range of applications. Examples include:
oRemote DVI display monitoring for medical, military, aerospace, industrial and traffic control applications.
oDigital Flat Panel Displays (FPD), Plasma Display Panels (PDP) and projectors in conference rooms and
auditoriums.
oKiosks with digital FPDs.
oColor LED signboards, FPDs and PDPs for information display at stadiums.
Use in conjunction with a FIBER-1X4-SMSC to extend up to 4 DVI monitors from a single video source up to 3280 feet
(1000 meters) away. (See page 5 for details.)

System Requirements
Hardware requirements
Graphic controller with a DVI port in your PC, SUN or Mac systems. It should support the maximum graphic
resolution of displays to be connected.
No special requirements for memory size, CPU speed and chipsets, if you’ve already properly installed your
DVI graphic controllers.
AC/DC Power Adapter Technical Advisory
The transmitter (Tx) module of the ST-1FODVI-SC is intended to be powered by your graphic card, depending on the
power supply capability of the graphic card you are using. If this is not possible, a separate power supply can be
ordered from NTI.
However, the receiver (Rx) module must be powered by the supplied AC power adapter.
Note: In general, most laptops or desktop PCs with PCI Express graphic card require using a separate 5VDC
power adapter for the transmitter.
INSTALLATION
Important: Please use the installation procedure below. Improper or no operation may result if the start-up sequence is
not correctly followed.
1. Carefully unpack the material included.
2. Check if the maximum resolution of the display is UXGA (1600x1200). Otherwise, follow the instructions for Self-EDID
Programming Procedure on page 6.
3. Plug the included 5VDC power adapter into an AC outlet. Plug the 5V power adapter to the power jack of the receiver.
Ensure the red LED is illuminated.

4. Connect simplex optical fiber (not supplied) between the transmitter and the receiver as shown in Figure 3
Figure 3- Connection of optical fibers
5. Plug the transmitter to the DVI receptacle of the DVI source (such as a PC).
Figure 4- Connection of the transmitter to the DVI source
Note: We recommend NOT to use any intermediate cable or adapter between the transmitter and the DVI source to avoid
undesirable performance degradation.

7. Power ON the PC and the display.
Caution: When you touch the surface of modules, the surface of modules may be
hot. This is normal.
TIP: If you want to display a video source on multiple monitors via fiber optics, install an NTI FIBER-1X4-
SMSC splitter.

Self-EDID Programming Procedure
The video source generally requires communication of display information (EDID). Display information (EDID) contains resolution
and timing information for your display.
ST-1FODVI-SC supports Self-EDID programming. Self-EDID programming means that the EDID from the display is stored in the
Transmitter. Use the Self-EDID programming feature if the resolution of the display is not WUXGA(1920x1200) because the
default resolution setting of the ST-1FODVI-SC is preset at 1920x1200, 60Hz. Follow these steps to record the EDID of the display
into the Transmitter unit.
Note1 : If you know that EDID is not required by the video source, Self-EDID programming is not necessary.
Note2 : The default EDID setting of the ST-1FODVI-SC is the VESA standard WUXGA (1920x1200) 60Hz.
1. Power ON the display.
Note: The Transmitter should not be connected to the display when the display is powered ON.
2. Connect the transmitter to the display.
3. Plug the included 5VDC power adapter into an AC outlet. Insert the 5VDC power adapter into the Transmitter.
4. The Self-EDID LED will blink rapidly for a few seconds and then be solid ON. If this does not happen, disconnect the 5VDC
power from the Transmitter, wait 10 seconds, reconnect the power, and try again.
Figure 7- Position of EDID LED
5. Disconnect the Transmitter from the display.
6. Disconnect power from the Transmitter, and connect the Transmitter to the video source.
7. Connect the Receiver to the display, and then power to the Receiver .
8. Connect a multimode optical fiber between the Receiver and Transmitter.
9. Reboot the PC.
If the Transmitter's LED does not illuminate, then disconnect the AC adapter from the Receiver and connect it to the
Transmitter instead. If the LED illuminates, then a second AC adapter will be needed. Contact NTI to place your
order for a PS4169 (US Plug).

TROUBLESHOOTING
The monitor displays only black screen.
Ensure that all plugs and jacks used by external power supplies are firmly connected. Ensure the blue LED is illuminated.
Ensure that the DVI ports are firmly plugged-in to the PC and display.
Ensure that the transmitter and receiver modules are connected correctly to the PC and display, respectively.
Check if the PC and display are powered ON and properly booted.
Reset the system by un-plugging and re-plugging the transmitter DVI port or receiver DVI port, or by un-plugging and re-
plugging the power cord plugs of the transmitter and receiver modules.
Re-boot up the system while connecting the optical DVI extension module.
Screen is distorted or displays noises.
Check if the graphic resolution is properly set. Go to the display properties of Windows and check the settings.
Ensure that the resolution is set to no greater than 1920x1200 at 60Hz refresh ratio.
Reset the system. Disconnect and reconnect the optical DVI cables or 5V power adapters.
