Frequently Asked Questions - DVI DL 201 Tx Extron

What is the maximum resolution supported by the DVI DL 201 Tx?

The DVI DL 201 Tx supports resolutions up to 2560x1600 @ 60 Hz in dual link mode. In single link mode, it supports up to 1920x1200 @ 60 Hz.

How many CAT cables are needed to connect the transmitter and receiver?

Three CAT 5/5e/6/7 twisted pair cables are required for dual link operation. For single link, only two cables (ports 1 and 2) are needed.

Can I use UTP cables instead of STP?

Yes, both UTP and STP cables work. However, STP cables are required to ensure FCC Class A and CE compliance, and for optimal performance.

How does the EDID Minder work?

The EDID Minder captures the EDID from a locally connected display and stores it. When the source boots, it reads the stored EDID, ensuring correct resolution even if the remote display is off.

Can the receiver be powered without its own power supply?

Yes, the receiver can be remotely powered by the transmitter via the twisted pair cable. A single power supply connected to the transmitter can power both units.

What is the maximum distance for 1920x1200 resolution?

With Extron DTP26 cable, up to 150 ft (45 m); with UTP, up to 100 ft (30 m). With STP, up to 125 ft (38 m).

How do I pass RS-232 control signals through the extender?

Connect the RS-232 control device to the 3-pole captive screw connector on the transmitter (Tx, Rx, GND). The signals pass through to the receiver's similar connector, which connects to the display.

What should I do if there is no video signal?

Check that the front panel LEDs are amber (power) and then green (signal). Ensure all three CAT cables are firmly seated and correctly connected. Verify DDC switch settings and power order: display on before source.

Is the DVI DL 201 Tx compatible with HDCP?

The extender is compatible with HDCP signals only when the EDID Minder is disabled. HDCP can be passed to only one display (local or remote) at a time.

Can I mount the transmitter in a rack?

Yes, using an optional 1U rack shelf kit (e.g., RSF 123 or RSU 126). The transmitter is 1U high and half rack wide.

Introduction

This user guide contains information about the Extron® DVI DL 201 Tx/Rx signal transmitter and receiver, with information on how to mount, install, and operate these units.

In this guide, unless otherwise specified, the terms "DVI DL 201" and "DVI DL 201 Tx/Rx" refer to both the transmitter (DVI DL 201 Tx) and the receiver (DVI DL 201 Rx). The term "transmitter" refers to the DVI DL 201 Tx, and "receiver" refers to the DVI DL 201 Rx.

About the DVI DL 201 Tx/Rx

The DVI DL 201 Tx and DVI DL 201 Rx are dual link DVI transmitter/receiver units. They can be purchased as a pair or as individual units.

Each purchased pair and each individual unit is shipped with a single external desktop 12 VDC power supply. A single power supply, connected to the transmitter, is able to power both devices.

Using three CAT 5/5e/6/7 twisted pair cables, DVI-D signals can be extended up to 100 feet (30 m) at resolutions up to 2560x1600 @ 60 Hz. This is significantly further than the 15 feet (5 m) specified for standard dual link DVI cables.

NOTES: The DVI DL 201 Tx/Rx works with unshielded twisted pair (UTP) cable or shielded twisted pair (STP) cable. However, STP cables are required to ensure FCC Class A and CE compliance.

Do not use skew-free cable. Extron strongly recommends DTP26 cable, especially when using high resolutions such as 1920x1200, 1600x1200, or 2560x1600. DTP26 cable is available as non-plenum (part number 22-214-03) or plenum (part number 22-215-03).

Twisted Pair Output and Input

Terminating shielded cable

CAT 5/5e/6/7 twisted pair cable is not provided with the transmitter/receiver pair. You may purchase cables that have been precut to the required length and terminated to the T586A or T586B standard (see the table on the next page).

Alternatively, purchase bulk cable and use the RJ-45 connectors (provided) to prepare your own terminated cables as described below.

NOTE: The transmitter and receiver pair works with unshielded twisted pair (UTP) or shielded twisted pair (STP) cables. To ensure FCC Class A and CE compliance, and for optimum performance, STP cables are recommended.

Do not use skew-free cable. Extron strongly recommends DTP26 cable, especially when using high resolutions such as 1920x1200, 1600x1200, or 2560x1600. DTP26 cable is available as non-plenum (part number 22-214-03) or plenum (part number 22-215-03).

1. Cut the cables to the required length. All three cables should be the same length.
2. Remove about 7/8 inch (2.2 cm) of the outer coat. If using STP cable, peel back the shielding and fold it over the top of the outer coat.

1. Cut away and discard the clear cellophane inner wrapper that extends beyond the folded back shielding.
2. Cut a piece of self-adhesive shielded aluminum tape (provided), remove the backing, and wrap it around the folded back shielding.

1. Separate the individual wires, and arrange them so that all eight wires are side by side in the same order as the T586A or T586B standard shown at the top of the next page. Both ends of a cable must be wired to the same standard (T586A or T586B).

1. Feed the wires into the RJ-45 connector.

1. Crimp the cable in the normal manner (see the figure below), folding the tangs of the connector over the shielded tape.

Diagram of a crimped connector with labeled parts (no text or symbols beyond label)

Connections

Use RJ-45 connectors to link the output from the transmitter to the appropriate input on the receiver. Three CAT 5/5e/6/7 twisted pair (TP) cables connect the transmitter with the receiver.

NOTE: The transmitter and receiver pair works with unshielded twisted pair (UTP) or shielded twisted pair (STP) cables. To ensure FCC Class A and CE compliance, and for optimum performance, STP cables are recommended.

Connect the output from the transmitter to the input of the receiver that has the same number:

• Transmitter port 1 connects to receiver port 1.
• Transmitter port 2 connects to receiver port 2.
• Transmitter port 3 connects to receiver port 3.

NOTE: Do not use skew-free cable. Extron strongly recommends DTP26 cable, especially when using high resolutions such as 1920x1200, 1600x1200, or 2560x1600. DTP26 cable is available as non-plenum (part number 22-214-03) or plenum (part number 22-215-03).

Single link/dual link DVI

Dual link DVI carries signals at resolutions up to 2560x1600 @ 60 Hz. Single link DVI carries signals at resolutions up to 1920x1200 @ 60 Hz.

Video Resolution (60 Hz)	Single Link Mode Dual Link Mode
	UTP STP/DTP	26 UTP STP/DTP26
1024x768	200 feet(60 m)	200 feet(60 m)	200 feet(60 m)	200 feet(60 m)
720p
1080i
1920x1200	100 feet(30 m)	125 feet(38 m)	100 feet(30 m)	150 feet(45 m)
1600x1200
1080p
2560x1600 N/A N/A	100 feet		(30 m)	150 feet(45 m)

NOTE: The transmission distance varies greatly depending on signal resolution and on the type of cable, graphic card, and display used in the system.

To operate in dual link mode, all three TP cables are required and both the source and display devices must support dual link DVI signals.

To operate in single link mode, only TP cables 1 and 2 are required. Dual link DVI is backwards compatible with single link DVI.

The DVI/HDMI 201 (single link) receivers can be used with the DVI DL 201 transmitter, in single link mode (using only TP cables 1 and 2).

DDC Switches

When the DVI-D source device boots up, it uses the Display Data Channel (DDC), a two-way communication protocol, to obtain Extended Display Identification Data (EDID) from the display device. This allows the source to output a resolution that matches the capabilities of the display.

A bank of three switches allows the user to determine how the source device will obtain the EDID. The EDID can be obtained directly from the display device, or from the internal memory within. The three switches are:

EDID Minder — This switch must be on for the EDID Minder function to be enabled. The factory default for this switch is the off position.

Default EDID — When the Default EDID switch is on (factory default; see figure at right), an EDID showing a typical dual link DVI display resolution of 2560x1600 @ 60 Hz is passed to the source device. The EDID Minder switch must also be on for the Default EDID switch to function.

Remote DDC — When this switch is off, the DDC is routed to the local monitor. When the switch is on, the DDC is routed to the remote display device.

See page 13 for more information about configuring these switches to provide the source device with the correct EDID.

Control Pass-through

The DVI DL 201 Tx/Rx cannot be controlled by RS-232 or IR controls. However, they are able to pass signals from a control device to a remote device that is controlled by those signals.

NOTE: The RS-232 and IR communications are via a passive pass-through only; the transmitter and receiver neither generate nor respond to these signals.

Use the three-pole, 3.5 mm captive screw connector on the transmitter to input RS-232 or IR signals from a control device. Use the corresponding connector on the receiver to pass signals to the output display.

NOTE: The ideal length of exposed wire in the stripping process is 3/16 inch (5 mm). If longer than 3/16 inch, the exposed wires may touch, causing a short circuit. If shorter than 3/16 inch, the wires can be easily pulled out even if tightly fastened.

Do not tin the wires. Tinned wire does not hold its shape and comes loose over time.

RS-232 signals

RS-232 signals are bidirectional — signals pass from the control device and replies return from the remote device. To connect the control device to the transmitter, or the receiver to the remote device, make the following connections, as shown at right:

• Tx to Tx
• Rx to Rx
  • ±(ground) to ±

DVI DL 201 Transmitter or Receiver

RS-232 Control or Display Device

NOTE: For information about controlling display devices with RS-232 commands, please refer to the user guide of that device.

IR signals

IR signals are one-way (from control device to the IR emitter that broadcasts the IR signal remotely). There are no responses and no requirement for a reverse pathway. To connect the control device to the transmitter or the receiver to the IR emitter, make the following connections, as shown at right:

• The Signal (S), from the control device to Tx of the transmitter.
• The ground (G) of the control device is connected to the ground ( ) of the transmitter.
• The Tx of the receiver to the S of the IR emitter.
• The ground ( ± ) of the receiver to the ground (G) of the IR emitter.

Power Input

1. Connect the captive screw connector from the supplied 12 VDC power supply into the power receptacle.

CAUTION: Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product. Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The power supply is to be located within the same vicinity as the Extron A/V processing equipment in an ordinary location, Pollution Degree 2, secured to the equipment rack within the dedicated closet, podium or desk. The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently fixed to building structure or similar structure.

Twisted pair cable 2, pin 5 carries a 12 VDC power signal. This remote powering feature allows a single power supply, connected to the transmitter, to power both the transmitter and receiver.

CAUTION: Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply, the transmitter, and/or the receiver. Identify the ground ( 12 lead by the ridges on the side of the cord (see the figure below).

Figure 6. Connecting Power to DVI DL 201 Tx/Rx

NOTE: See the second note on page 10 for important information about wiring captive screw connectors.

1. Connect the AC power cord of the power supply unit to a 110 or 220 VAC electrical source.

2. When the transmitter or receiver is getting power, either directly from the power supply or indirectly through the remote powering feature (receiver), the front panel LED lights amber.

Configuration

Using the EDID Minder to Read and Store EDID from a Display

During boot up, the DVI-D source device uses Display Data Channel (DDC) to obtain Extended Display Identification Data (EDID) from the display device. This allows the output signal to match the resolution and refresh rate of the display device.

The DVI DL 201 Tx/Rx uses the Extron EDID Minder, which allows the user to store and use EDID from any display device. To use this feature, follow these steps:

1. Disconnect all devices and cables from the transmitter and receiver.
2. Connect the desired display to the Local Monitor output of the transmitter. For best results, the cable for this connection should be 15 feet (4.5 m) or shorter.
3. Apply power to the transmitter and the display device. If necessary, connect the power supply to the transmitter.
4. Set the EDID Minder switch on the transmitter to the on (up) position (see the figure at right).
5. Set the Default EDID switch to the off (down) position (see the figure at right).
6. Set the Remote DDC to the off (down) position to allow DDC routing to go to the local monitor (see the figure at right).

NOTE: The EDID Minder extracts information only from the local monitor, not from the remote display.

1. Press and release the EDID Minder Store button. The LED next to the switch turns from green to amber. This indicates that the transmitter is reading and extracting the EDID from the display connected to the local monitor output.

When the information has been successfully extracted and stored in non-volatile memory, the LED returns to green.

1. Turn off the display and disconnect it from the transmitter.
2. Connect the transmitter to the receiver with the three twisted pair cables.

• Transmitter port 1 connects to receiver port 1.
• Transmitter port 2 connects to receiver port 2.
• Transmitter port 3 connects to receiver port 3.

1. Power up the transmitter and the receiver. A single power supply, connected to the transmitter can provide power to both units through the remote power connection.
2. Connect the remote display to the receiver output. A local monitor display can also be connected to the transmitter output at this time.
3. Connect the DVI source to the transmitter input.
4. Check that the transmitter switches are in the positions described in steps 4 to 6.
5. Power on the DVI source device. The source device reads and uses the EDID information stored in the transmitter memory and boots up with that resolution.
6. Power on the remote (and local) display device(s).

NOTE: All display devices must be capable of handling resolutions equal to or greater than that of the device used to set the EDID.

1. Set the EDID Minder switch to the on (up) position and the Default EDID switch to the on (up) position (see the figure at right). The position of the Remote DDC switch is not relevant.
2. Connect the source device to the transmitter input.
3. Connect the display device to the receiver output and, if required, the local monitor to the transmitter output.
4. Connect the transmitter to the receiver with the three twisted pair cables.

• Transmitter port 1 connects to receiver port 1.
• Transmitter port 2 connects to receiver port 2.
• Transmitter port 3 connects to receiver port 3.

1. Power on all devices.

2. The source boots using EDID showing a native resolution of 2560x1600, regardless of the display device.

NOTE: All display devices must be capable of handling resolutions equal to or greater than that of the device used to set the EDID.

Using Pass-through Mode with DDC Routed to a Local Monitor

1. Set the EDID Minder switch to the off (down) position and the Default EDID switch to the off (down) position (see the figure at right). The position of the Remote DDC switch is not relevant.
2. Connect the source device to the transmitter input.

1. Power on the local monitor, if required.

NOTE: The remote display device must be capable of handling a resolution equal to or greater than that of the local monitor.

Setup and Operation

1. Determine which source will be used for the EDID information and configure the DDC switches appropriately (see pages 13 to 16). If necessary, use the EDID Minder to read and store information from a display (see pages 13 to 14).
2. Prepare twisted pair cables (see "Terminating shielded cable").
3. Connect the transmitter to the receiver (see "Connections")
4. Connect the source device to the transmitter (see "DVI-D input"). Do not power on the source device at this time.
5. Connect the display device to the receiver (see "DVI-D output"). If required, connect a local monitor to the transmitter.
6. If required, connect any RS-232 or IR control devices (see "Control pass-through").
7. Connect the power supply to the transmitter (see "Power input").

CAUTION: Read all the Cautions in the "Power Input" section.

1. Power on the display device.
2. Power on and boot up the source device.

Troubleshooting

If the DVI DL 201 Tx/Rx does not provide a high quality output signal, check the following possibilities before contacting your Extron representative (see the back cover for contact information). Be sure to read all the suggestions as many of the issues have several possible solutions.

No output signal — Check that the front panel LEDs for both the transmitter and receiver are on (lit amber). If they are not, check the power supply connections to the units.

If a single power supply is being used to power both units, it must be connected to the transmitter.

NOTE: Do not try to power both units with a single power supply connected to the receiver as that will not provide adequate power to the transmitter.

There are some circumstances, particularly with longer Unshielded Twisted Pair (UTP) cable runs, where the receiver may not get adequate power. Under these circumstances, it may be necessary to use two separate power supplies, one for the transmitter and one for the receiver.

Insure all three twisted pair cables are firmly seated in the correct receptacles.

No output signal or poor quality signal — Check the integrity of the UTP or STP cables between the transmitter and the receiver.

NOTES: The transmitter and receiver pair works with unshielded twisted pair (UTP) or shielded twisted pair (STP) cables. To ensure FCC Class A and CE compliance, and for optimum performance, STP cables are recommended.

Do not use skew-free cable. Extron strongly recommends DTP26 cable, especially when using high resolutions such as 1920x1200, 1600x1200, or 2560x1600. DTP26 cable is available as non-plenum (part number 22-214-03) or plenum (part number 22-215-03).

• Ensure that the twisted pair cables are terminated correctly and to the same standard at both ends (see "Terminating shielded cable").
• Ensure that each RJ-45 connector is firmly seated in its receptacle and that each transmitter port is connected to the correct receiver port (see "Connections").
• Ensure that the length of the twisted pair cable does not exceed the guidelines for single link or dual link connections (see "Single link/dual link DVI").

Image loss or jitter — DVI signals run at very high frequency and are especially susceptible to bad video connections, too many adapters, or cables that are too long. To avoid loss of an image or introduction of image jitter:

• The DVI cable on the input to the transmitter or the output from the receiver should not exceed 10 feet (3 m).
• Use only cable designed for DVI signals.
• Limit or avoid the use of adapters, patch panels, or couplers with the input DVI cables, the output DVI cables, and/or the twisted pair cables. Additional links in the chain reduce signal integrity and overall cable length performance.
• Always turn on the display before the DVI video source in order for the source to retrieve the DDC from the display.

No video signal or incorrect resolution or refresh rate — If the source device is not able to obtain EDID information when it is being powered on, it may not be able to send a video signal or the signal may have the wrong resolution or refresh rate.

• Ensure that the DDC DIP switches are set correctly for the EDID source (see "Configuration").
• The source device must be powered on after the display device providing the EDID source has been powered on.

Incorrect color or tint — Ensure that the twisted pair cables are terminated correctly and to the same standard on both ends of the cable (see "Terminating Shielded Cable").

Display device shows a flashing black or blue screen, snow, or other distortion — A device that is not High-Bandwidth Digital Content Protection (HDCP) compliant may be receiving HDCP-encrypted signals.

The DVI DL 201 Tx/Rx is compatible with HDCP signals only when the EDID Minder is disabled. HDCP signals can be passed through to only one display (remote or local) and only that display shows the signal correctly.

Signal on local monitor but not on remote display — Check that both output devices (local and remote) can handle resolutions equal to or greater than the EDID source.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:

1. Elevated operating ambient temperature — If the unit is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma: +122 °F, +50 °C) specified by Extron.

2. Reduced air flow — Install the equipment in the rack so that the equipment gets adequate air flow for safe operation.

3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of the equipment nameplate ratings should be used when addressing this concern.

5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).
