Extron electronics DVI 104 Rx Manuale utente

Description

The Extron DVI 104 Tx and DVI 104 Rx are ﬁber optic transmitter/

receiver units that extend DVI signals up to 1,640' (500 m) 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.

aPower 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.

N 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.

bLC 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.

N 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, etcetera.

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.

Top panel features

cLED — Both the transmitter and

receiver have LEDs on both sides

that light blue 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”).

dThumbscrews — Use the

thumbscrews to secure the

transmitter or receiver to its

connector.

Side panel features (transmitter only)

eEDID 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. (For more information, see the next

section, “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 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 light a solid

blue.

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.

NThe 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 LEDs are no

longer blinking, disconnect the transmitter from both the power

and the display device.

NOnce 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. The LEDs illuminate steadily.

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 source’s DVI input, and tighten the

thumbscrews.

10. If required, apply power to the transmitter. The LEDs illuminate

steadily.

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,

etcetera.)

12. Turn on the source device. The source device reads the

information stored in the transmitter and boots up to that

resolution and refresh rate.

Troubleshooting

Display does not show an image

Ensure that all plugs and jacks used by the external power•

supplies are ﬁrmly connected.

Ensure that the LEDs for both the transmitter and receiver are lit.•

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.

Ensure that the source device and output device are powered on•

and have booted up 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.•

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 below).

This provides the extra leverage required to keep the locking catch

in place and hold the cable securely.

Adjusted Position

Locking catch Release catch

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• 1,640' (500 m).

Ensure• that the cables are high quality multimode cable and are

terminated with securely ﬁtting plugs.

Ensure that the resolution is correctly set, using the EDID Minder•

(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.
