DVI 104 Tx/Rx • Setup Guide

Description

The Extron DVI 104 Tx and DVI 104 Rx are fiber optic transmitter and receiver
units that extend DVI signals up to 500 meters (1,640 feet) using four multimode
fiber optic cables.

The transmitter plugs directly into the source device and the receiver plugs
directly into the display device.

The transmitter/receiver pair can handle DVI video signals with resolutions
up to 1920 x 1200 or 1080p at 60 Hz.

Optional four-fiber multimode cables are available in varying lengths.

Power input — The transmitter and receiver both have plugs for a

Up to 500 meters (1640 feet)

1 2

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.

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.

both sides that light green when the unit is receiving power.
The LEDs on the transmitter also function as a status
indicator for the EDID minder feature (see “Setup and

Operation”).

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”).

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 ber 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 light a solid green.

3. Gently press and release the EDID Minder storage button, using a pointed device, such as a

paper clip. Both LEDs should blink twice and turn off, although power is still connected.

4. Power on the display device.

5. Connect the transmitter directly to the DVI input of the display device. The 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 LEDs stop blinking. They may light
steadily 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

5

6. Once the capture and storage are complete and the 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.
