DVI 104 TX/RX • User Guide
Features
Power supply — Separate power supplies are provided for both the transmitter and receiver.
Power LEDs — The LEDs are on the top and bottom panels of both the receiver and transmitter. They illuminate green when the unit is receiving power.
No mounting hardware required — The units plug directly into the source device (transmitter) or output device (receiver) and take up very little space.
EDID Minder — The DVI 104 transmitter is able to capture and store the resolution and refresh rate of the display device, which ensures that the source boots up with the correct resolution.
Long cable runs — The DVI 104 Tx/Rx uses four fiber optic cables to extend video signals up to 500 meters (1,640 feet). The cables must be either 62.5/125 multimode cable or 50/125 multimode cable.
High resolution signal transmission — The units transmit signals at resolutions up to 1920 x 1200 or 1080p @ 60 Hz.
High rate of data transfer — The units can transmit signals at up to 1.65 Gbps

Power input — The transmitter and receiver both have plugs for a 3.5 mm jack to provide
5 VDC to the unit.
The center pin of the jack carries +5 VDC; the outer shell of the jack is the negative rail.
NOTES:
• If the source device is able to provide 5 VDC on pin 14 of its DVI output, the transmitter can draw power from the source device. If the source is a laptop or a
PC using a PCI-E graphics card, it will not be able to provide enough power and the transmitter must be powered with a separate external power supply.
• The receiver must be powered by an external power supply through the power input plug.
b
LC jacks — Four fiber optic cables connect the transmitter to the receiver. The cables connect to the four female LC jacks in each of the units.
A label on the top panel identifies the unit as the transmitter or receiver and identifies the fiber optic port numbers and the power input.
NOTES:
• For the transmitter, port 1 is closest to the power input and port 4 is furthest away. For the receiver, port 4 is closest to the power input and port 1 is furthest away.
• Although the orientation is reversed, ports with the same number must be connected by the same cable, so that port 1 on the receiver is connected to port 1 on the transmitter, and so forth.
Insert the end of the fiber optic cable into the appropriate plug on the transmitter or receiver. The locking catch should snap into the slot and hold the cable securely in place.
Locking catch
If the cable is loose or slips out of the slot easily, move the release catch from its normal position above the locking catch, to the adjusted position under the locking catch (see the figure above right). This provides the extra leverage required to keep the locking catch in place and hold the cable securely.

EDID Minder storage button (transmitter only) — A recessed switch activates the transmitter to capture and store EDID information from the display device. This allows the source device to provide a signal with a resolution and refresh rate matching the needs of the display device (see “

Setup and Operation
When using the DVI 104 Tx/Rx for the first time or if the display device is changed, it is essential to set up the EDID Minder. The setup process places EDID information on a EEPROM chip in the transmitter, which allows the video source to boot up correctly. This process is described below in steps 1-6. If you have already set up the EDID Minder, proceed to step 7.
1. Ensure that the source, the display, the transmitter, and the receiver are all powered off and that the fiber optic cables are unplugged from the transmitter and the receiver.
2. Apply power to the transmitter by inserting the cable from the external power supply into the input jack. The LEDs should illuminate a solid green.
3
DVI 104 TX/RX • User Guide
3. Press and release the EDID Minder programming button by gently inserting a pointed device, such as a paper clip, into the recess on the side of the transmitter. The green LED should blink twice and turn off, although power is still connected. The transmitter is ready to capture EDID information from the display device.
4. Power on the display device.
5. Connect the transmitter directly to the DVI input of the display device. The green LEDs on the transmitter blink rapidly for a few seconds to indicate that it is reading and storing EDID information from the display device.
When the information has been captured and stored, the green LEDs stop blinking. They may light a solid green or they may turn off, depending on the display device.
NOTE: The transmitter must remain connected to both the display device and the power supply for the entire time that the
EDID capture is taking place.
6. Once the capture and storage are complete and the green LEDs are no longer blinking, disconnect the transmitter from both the power and the display device.
NOTES:
• Once the transmitter has captured the EDID information from the display device, the information is stored on an EEPROM chip in the transmitter. Therefore, this calibration needs to be performed only once, as long as the display device is not changed.
• If the display device is changed, repeat steps 1-6 to capture and store the EDID information for the new device.
7. Apply power to the receiver by inserting the cable from the external power supply into the input jack. The LEDs should illuminate a solid green.
8. Ensure that the display device is still powered on, connect the receiver directly to the DVI input, and tighten the thumbscrews.
9. Ensure that the PC or source is powered off, connect the transmitter directly to the DVI input, and tighten the thumbscrews.
10. If required, apply power to the transmitter by inserting the cable from the external power supply into the input jack. The LEDs should illuminate a steady green.
NOTE: If the PC or source is able to provide 5 VDC on pin 14 of its DVI output, the transmitter can draw power from the source device. If the source is a laptop or a PC using a PCI-E graphics card, the source device cannot provide enough power and the transmitter must be powered with a separate external power supply.
11. Connect all four fiber optic cables between the transmitter and receiver. Pay attention to the orientation of the LC connectors and ensure that each cable joins ports with the same number (port 1 of the transmitter must be connected to port 1 of the receiver, and so forth).

• Ensure that all plugs and jacks used by the external power supplies are firmly
Locking catch connected.
If the cable is loose or slips out of the slot easily, move the release catch from its normal position above the locking catch, to the adjusted position under the locking catch (see the figure at right). This provides the extra leverage required to keep the locking catch in place and hold the cable securely.
• Ensure that the green LEDs for both the transmitter and receiver are on.

Normal Position
• Ensure that the correct EDID information has been stored on the transmitter’s
EDID Minder. When using the DVI 104 Tx/Rx for the first time or if the display device is changed, it is essential to set up the EDID Minder as described in
steps 1-6 of “ Setup and Operation
” on page 3 of this guide.
Adjusted Position
• Ensure that the source device and output device are powered on and have booted correctly.
• Ensure that the fiber optic cables are connecting the correct ports. A port on the transmitter must be connected to the same numbered port on the receiver. For example, port 1 of the transmitter must be connected to port 1 of the receiver.
• Ensure that the fiber optic cable jacks are securely seated.
• Ensure that the transmitter is firmly plugged into the source device and the receiver is firmly plugged into the output device.
• Try resetting the system by unplugging and reconnecting the DVI connectors or the power jacks.
• Try rebooting the computer.
Screen is distorted or displays noise
• Ensure that the cable length does not exceed 500 meters (1,640 feet).
• Ensure that the cables are high quality multimode cable and are terminated with securely fitting plugs.
•
Ensure that the graphic resolution is correctly set (see “ Setup and Operation
”).
• View the “Display Properties” of the source device to check the output resolution. The resolution and refresh rate must match the capabilities of the display device and must not exceed 1920 x 1200 at 60 Hz.
• Try resetting the system by unplugging and reconnecting the DVI connectors or the power jacks.
