1-9 Regulatory Statements

Welcome!

Congratulations on your purchase of the PureLink OLC II Optical DVI (Digital
Visual Interface) Extension Module. This manual contains information that will
assist you in installing and operating the product.

Product Description

The OLC II optical DVI module transmits four (4) optical data, Red, Green,
Blue and clock and can be extended up to 2,000 meters (6,500ft) over two LC
multi or single-mode fiber at WUXGA (1920x1200) at 60Hz vertical refresh
rate. The EDID (Extended Display Identification Data) in a display can be read
and restored by just plugging once transmitter to the display. This Self-EDID
management feature makes the installation of OLC II more easy and flexile
at any variable resolution display systems. For your convenience, WUXGA
EDID would have been done before shipment as a factory default.

1-8 Warranty Information

System Requirements for Setup

 Hardware requirements

 You have to have a DVI graphic controller or card having a DVI

port in your PC, SUN or Mac systems. It should support the
maximum graphic resolution feature 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 or cards.

 Software requirements

 No special restrictions, if you’ve already properly installed your

DVI graphic controller in your OS.

 AC/DC Power Adapter Technical Advisory

The transmitter (Tx) module of OLC II is designed for power
protection circuit from conflict of power supply between the external
DC power adapter and your graphic card through the DVI pin. It offers
an option of whether to use an AC/DC power adapter depending on
power supply capability of the graphic card through the +5V pin, you
are using.

However, the receiver (Rx) module should be supplied by an AC/DC

power adapter.

Note 1: In general, most of laptops or desktop PCs with PCI Express

graphic card require using an AC/DC power adapter for the transmitter
module.

Note 2: If you use laptop or Desktop PC with PCI Express graphic card,
we recommend using 5V power adapter for the transmitter.

Troubleshooting

The display displays only black screen.

- Ensure that all plugs and jacks used by external power supplies (both
Dtrovision and others) are firmly connected. Ensure the blue LED ON.

- Ensure that the DVI ports are firmly plugged in to the PC and display.

- Ensure that the transmitter and receiver modules plugged correctly to the
PC and display, respectively.

- Check if the PC and display are powered on and properly booted.

- Reset the system by de-plugging and re-plugging the transmitter DVI port or
receiver DVI port, or by de-plugging and re-plugging the power cord plugs of
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 tap the settings.

- Ensure that the resolution sets less than WUXGA (1920x1200) at 60Hz
refresh ratio.

- Reset the system. Disconnect and reconnect the optical DVI cables or 5V
power adapters.

Maintenance

No special maintenance is required for the optical DVI module and power
adapters. Ensure that the DVI modules and power adapters are stored or
used in a benign environment free from liquid or dirt contamination.

There are no user serviceable parts. Refer all service and repair issues to
Dtrovision.

1-6 Troubleshooting, Maintenance, Technical Support

Installation

Important: Please use the installation procedure below. Improper or no
operation may result if the start-up sequence is not correctly followed.

Step 1

Carefully unpack the contents of the shipping group.

Step 2

Plug the 5V power adapter to the power jack of the transmitter. Ensure the
blue LED ON after blinking two times.

Figure 2 – Connection of power adapter to the transmitter

Note: You don’t need to connect the power adapter to the transmitter if the

graphic source provides enough power to operate the transmitter. Please,
refer to AC/DC Power Adapter Technical Advisory on page 1-2.

Step 3

Please, check if the maximum resolution of the display is UXGA (1600
x1200). Otherwise, follow the instructions for Self-EDID Programming

Procedure on page 1-5.
Step 4
Plug the 5V power adapter to the power jack of the receiver. Ensure the blue

LED ON.

Figure 3 – Connection of power adapter to the receiver

1-3 Installation

Step 5

Connect LC optical fiber between the transmitter and the receiver as shown in
figure 4.

Figure 4 – Connection of optical fibers

Note: Both of single-mode and multi-mode fiber are applicable to OLC II up to

500meters. In the case of longer than 500meters, you have to use single-mode
fibers.

Step 6

Plug the transmitter to the DVI receptacle of the DVI source such as PC.

Figure 5 – Connection of the transmitter to the DVI source

Note: Be recommended NOT to use any intermediate cable or adapter between
them to avoid undesirable performance degradation.

Step 7

Plug the receiver to the DVI receptacle of the display.

Figure 6 – Connection of the transmitter to the display

Step 8

Make the PC and the display power ON.
Note: You can replace any DVI cable into an OLC II by following the Step1 to 7,

while all powers of PC and display are ON.

1-4 Installation

Self-EDID Programming Procedure

The graphic source equipment generally requires communication of display information
(EDID). Display information (EDID) contains resolution and timing information for your
display.

OLC II supports Self-EDID programming. Self-EDID programming means that the
EDID from the display is stored in the transmitter. You should use Self-EDID
programming feature if the resolution of the display is not UXGA(1600x1200). 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 source, Self-EDID
programming is not necessary.

Note2 : The factory default EDID setting is programmed in the VESA standard of
UXGA (1600x1200) 60Hz.

Step 1

Power on the display.

Step 2

Apply the 5V DC power adapter to the transmitter.

Step 3

Push the EDID PRGM. button of the transmitter with a pointy pin. Hold down
the button for 3 sec and release it.

Self-EDID LED EDID-PRGM. button

Figure 7 – Position of EDID-PRGM. button and Self-EDID LED

Step 4
Connect the transmitter to the display while turned on, not to the PC. The

LED on the transmitter will begin to blink once. Blinking indicates reading the
EDID.

Step 5

Disconnect the transmitter from the display.
