1.0 System Overview
The DVI Fiberlynx from Lightwave Communications is a fiber optic extension
system for computers requiring high-resolution TMDS-interface video for flat
screen monitors and other digital high-resolution DVI-D devices. A user may be
located up to 1500 feet from the CPU and have complete interaction with the
CPU through keyboard, mouse, serial, video, and audio devices.
DVI Fiberlynx Receiver (top) and Transmitter (bottom) and Fiber Optic Cable
The DVI Fiberlynx system consists of a matched pair of units: a Transmitter and
a Receiver. The transmitter is located with the CPU, while the receiver is located
with the user peripherals (keyboard, mouse, monitor, etc.).
The DVI Fiberlynx provides the following connections:
•DVI-D (digital only) Input from the Host CPU
•Local DVI-D (digital) Video Output at CPU End
•Remote DVI-D (digital) Video Output (primary DVI output) at User end
•Auxiliary DVI-D (digital) Video Output (identical to primary) at User end
•DB9 Serial Interface (female on Transmitter, male on Receiver)
•3.5mm Stereo Microphone audio
•3.5mm Stereo Line-level audio
•DVI Keyboard and Mouse Personality Modules:
PS/2 format (two MiniDIN6), USB format, or SUN (one MiniDIN8) format
•Local Keyboard and Mouse connections (optional) at Transmitter end
•Universal AC Power Input using IEC cordset
•Six-strand fiber optic using ST connectors

Lightwave Communications DVI Fiberlynx

The DVI Fiberlynx system provides keyboard emulation and carries the keyboard
and mouse signals through the Transmitter to the Receiver end. The Personality
Modules must be used as a matched set (e.g., PS/2 on both ends, or USB on
both ends, etc.). No 'breaks' are sent to the CPU (which might cause the CPU to
reset), even if the DVI Fiberlynx units lose power, as long as the keyboard cable
remains connected to the Transmitter.
The DVI video record (DDC) is maintained in the event the DVI Fiberlynx is
powered off, as long as the DVI input cable remains connected to the
Transmitter. The CPU, or its video output, does not need to be restarted in this
case.
2.0 Installation
Installation of the DVI Fiberlynx is simple and requires only simple hand tools.
Each Fiberlynx transmitter or receiver can be mounted in a standard 19-inch
rack, or may be placed on a bench or table.
The DVI Fiberlynx has been classified a CLASS 1 LASER Product in accordance
with standards IEC 60825-1 and IEC 60825-2. Always operate the product in
accordance with these instructions.
Do not open the DVI Fiberlynx cases; there are no adjustments or user-
serviceable parts inside.

2.1 Site Preparation
1. Shutdown the CPU and disconnect the user peripherals (keyboard,
mouse, monitor, etc.).
2. Move the CPU and the user devices to their respective operating
locations. Standard cable kits provide 6 feet of copper cable length
between the CPU and the Transmitter unit; other lengths are available.
3. Run a 6-strand fiber optic cable with ST connectors between the CPU
location and user station. Fiber optic cable is available in custom and
standard lengths from Lightwave Communications.
Caution: Do NOT look at the LASER outputs through your fiber optic cable
or through reflection off a shiny surface. The LASER light can be harmful to
your vision.
4. Provide AC power connections for the DVI Fiberlynx units at each
location, as well as power for the CPU and any powered user peripherals
(such as a monitor and speakers). The DVI Fiberlynx uses a universal
power supply.
2.2 Connecting Fiber Optic Cable
1. Install the Transmitter and Receiver units close to their final locations. If
not already in place, run the fiber optic cable to these locations with
enough slack to prevent strain from damaging the cable.

(i.e., red on Transmitter to red on Receiver, blue to blue, green to green,
etc.). Data Out on the Transmitter is connected to Data In on the
Receiver, and vice-versa. Try to use the strand with the color indicated on
the connector; note any substitutions to avoid confusion.
Data 0, Data 1, Data 2 and CLK provide the video signal over the fiber.
Data Out and Data In provide the Keyboard, Mouse, Serial data and
Audio signal path over fiber.
3. Use the provided strain relief device to prevent damage to the fiber optic
cable. Secure the fiber optic cable using a tie-wrap, or using the provided
T-nut and a clamp, or both, depending on what works best for your site.
Dress the cable so it will not be disturbed.

2. Install the Personality Module, if not already in place. The Transmitter
Personality Module is used in the DVI Fiberlynx Transmitter. To install it,
remove the Personality Module blank cover (two screws), slide the
Transmitter Personality Module in, and secure it in place with its two
screws (finger tight is adequate).
3. Connect the keyboard and mouse ports from the CPU to the keyboard and
mouse ports labeled "TO CPU" on the personality module in the DVI
Fiberlynx transmitter. Use the PS/2 cables provided in the Cable Kit.
4. Connect the CPU audio ports to the transmitter using the provided 3.5 mm
stereo audio cables. The port marked “MIC IN” on the transmitter connects
to the microphone port on the CPU, while the “LINE OUT” port on the
transmitter connects to the speaker port on the CPU.
5. Connect the CPU serial port to the transmitter SERIAL port (DB9F on
Transmitter chassis) using the provided male-to-female serial cable.

4. Connect the digital video output of the CPU to the DVI IN connector of the
transmitter using the provided DVI-D cable. A monitor may be attached to
the DVI OUT connector to view the video output of the CPU locally.
Note: The DVI Fiberlynx interface uses DVI-I connectors for compatibility with all
DVI-type cables (DVI-D and DVI-I). The system configuration supports
Digital DVI (DVI-D) only. The analog leads are not supported.

7. Plug in the AC cordset into the rear of the DVI Fiberlynx. Connect the cord
to AC power and turn on the power switch. The two status LEDs found on
the front panel of the unit should light.
8. (Optional) If using a local keyboard and mouse for testing or during setup,
you may connect a Keyboard and Mouse to the Transmitter's personality
module's 'LOCAL' connectors. Connect your DVI monitor to the DVI OUT
connector on the Transmitter.
Note: The DDC video record must be established by the Video Source (your
CPU's video card) before any video signal will be present. To get the
signal, the DVI Fiberlynx must be turned on, the Monitor must be turned
on and connected, and then the CPU must be turned on (or video
restarted by some other method). See Section 3.1 for more information.
If the DVI Fiberlynx Transmitter is connected to the Receiver, the video
record will be generated from the Monitor connected to the Receiver unit.
If the Receiver is not connected, the video record will be generated from
the Monitor attached to the DVI OUT connector on the Transmitter.

5. Connect the Receiver to AC power and turn on the switch. The status
LEDs found on the front of the unit should light. The Monitor and the CPU
may be powered up at this time.
2.5 Power Up the Equipment
The video signal from your DVI video source requires that the DVI monitor is
connected and turned on before the signal will start. If the signal is lost (cable is
unplugged, etc.) the signal will be discontinued and will not recover; the video
source must be restarted. This often means that your CPU must be restarted.
Power Up your equipment in this order (after all wiring connections are done):
1. Power Up your Monitor
2. Power Up the DVI Fiberlynx Receiver and Transmitter units
3. Power Up your CPU.
During power-up of your CPU, the video card generates a video record
depending on the DVI monitor that it senses is connected to its output. See
section 3.1 for more information relating to the video record.

Lightwave Communications DVI Fiberlynx
www.lightwavecom.com November 200112
3.0 Operation
Once the CPU is operating, the DVI Fiberlynx is transparent to the user. It will
appear as though the user peripherals are directly attached to the CPU. There
are no user adjustments relating to the DVI Fiberlynx.
Both the transmitter and receiver may be powered off while the CPU is on. As
long as all cables remain connected between the CPU and transmitter, the CPU
will continue to operate without error due to hardware disconnection.
If there is no Data In / Data Out signal to the receiver (i.e., if the transmitter has
no power or there is no communication between the two units), the three
keyboard status lights (Num Lock, Caps Lock, and Scroll Lock) will flash together
to indicate an loss of data signal to the user.
If the DVI IN signal (between the CPU and the DVI Fiberlynx Transmitter) is
broken at any time, the DVI signal will be discontinued by the CPU, and will not
automatically restore. To restore the signal, reboot your CPU.
3.1 Video Record
During initial power-up of the CPU, a video record is established for the DVI
monitor connected to your CPU. The video record complies with VESA Display
Data Channel (DDC) specification DDC2B. The video record determines the
operational characteristics of video output from the digital video interface.
If more than one monitor is connected, the DVI Monitor connected to the DVI
OUT of the DVI Fiberlynx Receiver is the first priority in establishing that video
record. The monitor connected to the DVI OUT of the Transmitter unit is the
second priority (used only if a Monitor is not connected to DVI OUT on the
Receiver).
A DVI Monitor on the DVI AUX port cannot be used to set up the video record.
3.2 Video Resolution
The DVI Fiberlynx supports resolutions from 640x480 (VGA) to 1600x1200
(UXGA).
3.3 Front Panel LEDs
The front panel LEDs indicate the status of the DVI Fiberlynx. The transmitter
and receiver lights indicate status as marked on the front panel. The tables below
outline the light status and possible solutions to the status abnormalities. Note
that any flashing or blinking LEDs will not flash in step; all LEDs will flash at
separate rates.

Lightwave Communications DVI Fiberlynx
