Black Box DVI-D USB Fiber Extender Single-Mode with Audio specifications Overview, Installation

Chapter 4: Operation/Chapter 5: Application Diagram

4. Operation

The LEDs on the Extender Units show the real-time status indicating the linking and communication between the Console Unit and Computer Unit. Users can identify the present status through the LED indicator on the top. See Figures 2-3 and 2-6 and Tables 2-1 and 2-2.

The quality of the output signal will depend largely upon the quality of video source, cable, and display device used. Low-quality cables degrade the output signal causing elevated noise levels. Use the proper cable and make sure the display device can handle the resolution and refresh rate selected.

Chapter 3: Installation

3. Installation

•Power off all devices that will be connected to this system.

•Make sure that all devices you will connect are properly grounded.

•Place units away from fluorescent lights, air conditioners, and machines that are likely to generate electrical noise.

•Determine where the Console Unit and the Computer Unit will be located.

•Use SC to SC duplex single-mode fiber optic cable (8–10 µm) for the interconnection between Console Unit and Computer Unit.

•Make sure that the fiber cable length is long enough for the connection between the Console Unit and the Computer Unit to prevent having to splice fiber.

•Never attempt to disassemble or reassemble the enclosure for any purpose. This may cause personal injury and/or property damage.

Considerations for Duplex Optical Fiber Installation

1.Users may need to order appropriate cable lengths conforming to the application environment; however, the maximum cable length should not exceed 3200 ft. (1000 meters). Otherwise, the video resolution signal may degrade.

2.Do not exceed the cable bend radius. Fiber optic cable can break when kinked or bent too tightly, especially during pulling.

3.Do not twist the cable. Twisting the cable can stress the fibers. Tension on the cable and pulling ropes can cause twisting.

CAUTION: Do not look into the ends of any fiber optic cables. You might be exposed to harmful invisible laser radiation.

4.Follow the cable manufacturer's recommendations. Fiber optic cable is often custom designed for the installation, and the manufacturer may have specific instructions on its installation.

Installing the Extender

Users can connect the video source and keyboard and mouse ports to the Computer Unit; connect the keyboard, mouse, and monitor to the Console Unit; and use an SC to SC duplex fiber optic cable for the SC-SC fiber port connection between the Console Unit and the Computer Unit. After all device connections are completed, connect the provided power cord into an appropriate power source and plug the opposite end into the power connector on the Unit to power up.
