DVI DA2 and DVI DA4 Features

• External power supply — The DVI DA2 and DVI DA4 are powered by an external 12 VDC power supply (provided with the units).
• DVI-D input — Both distribution amplifiers accept one single link DVI-D input with a range of resolutions up to 1920 x 1200 or 1080p @ 60 Hz.
• Input equalization — Input Equalization (EQ) conditions the input signals to ensure the integrity of the signals delivered to the output devices.
  • DVI-D outputs — The units drive two (DVI DA2) or four (DVI DA4) single link DVI-D output signals.

- DDC routing to the local monitor — Output 1 is used as a DDC reference and is labeled "Local Monitor" for easy reference. The video source uses the bidirectional DDC to communicate with the local monitor, which allows the source to determine the resolution and refresh rate of the signal that it sends.

NOTES:

• Since output 1 is used as the reference, all other display devices must be capable of handling resolutions equal to or greater than that of the local monitor.
• The actual signal transmission distance can vary greatly and depends on signal resolution, cable type, cable quality, graphics card, and the display used in the system.

- Versatile mounting options — Both units are 1U high, 3 inches (7.62 cm) deep, and 1/2 rack (8.7 inches or 22.1 cm) wide, allowing them to be conveniently mounted in a rack, mounted under a desk, or set on a tabletop.

Installation Overview

Both distribution amplifiers can be placed on tabletops, or mounted under furniture or in racks by following these steps:

1. Turn off all electrical equipment. Make sure that the input sources, the DA and the output display(s) are all turned off and all power sources and signal cables are disconnected.
2. Mount the unit (see Mounting page 5).
3. Connect the cables (see DVI Connections on page 3).
4. Plug in the power supply (see page 3), then turn on the display devices and input devices.

② Input connector
③ Output connector
④ Local Monitor connector

① Power input — Connect the provided power supply to the 3.5 mm, captive screw power receptacle.

NOTES:

• The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inch (5 mm).
• If the exposed section is longer, the exposed wires may touch, causing a short circuit between them.
• If it is shorter, the wires can be easily pulled out, even if tightly fastened by the captive screws.
• Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.

Figure 4. Power Connection

ATTENTION:

• This product is intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS,” rated 12 VDC, maximum 1.0 A. Always use a power supply supplied 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 AV 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.

DVI Connections

② Input connector — Connect the input signal to the female DVI connector. The DVI input signal is equalized to ensure integrity.

③ Output connectors — Connect up to two (DVI DA2) or four (DVI DA4) DVI-D outputs to display devices, using the female DVI connectors.

NOTE: The outputs are not HDCP compatible.

④ Local Monitor connector — Output 1 (Local Monitor) is used as a Hotplug Detect, a DDC clock, and a DDC data reference. For the input device to provide a signal at the correct resolution and refresh rate, there must be a display device connected to output 1.

NOTE: Although the source device, local monitor, and remote display devices all connect to the distribution amplifiers through DVI-I connectors, the DVI DA2 and DVI DA4 are compatible only with single-link DVI-D video signals.

To enable the units to accept sources providing HDMI signals or to provide signals to displays that accept HDMI signals, use a HDMI to DVI adapter or cable, such as the Extron HDMIF-DVIDM female HDMI to male DVI-D adapter or the Extron HDMI M-DVI-D M series of male HDMI to male DVI cables.

The input signal is one single link DVI-D with a resolution range up to 1920x1200 or 1080p @ 60 Hz.

Input EQ conditions input signals to ensure the integrity of the signals delivered to the output devices.

NOTES:

• The actual signal transmission distance can vary and depends on the signal resolution, cable quality, graphics card, and display used in the system.
• To ensure proper operation, display devices connected to outputs 2 through 4 must be able to handle resolutions equal or greater than that of the local monitor on output 1.

DVI Connector Pin Assignments

The illustration below shows the pin assignments for the male and female DVI-I connectors.

NOTE: Although DVI-I dual link connectors are used, the DVI DA2 and DVI DA4 are compatible only with single-link DVI-D video signals.

Operation

To operate the unit (see figure 3 on page 2 and figure 4 on page 3):

1. Connect the power supply.
2. Connect and power on the Local Monitor.
3. Connect and power on any other output displays.
4. Connect and power on the source device.

NOTE: Output 1 (Local Monitor) is used as a DDC reference and must be connected to the distribution amplifier before the source device is powered on. If the source device cannot communicate with the local monitor 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.

If there are any problems, consult the Troubleshooting section below.

Troubleshooting

• No output signal — Check that the front panel LED is lit. If it is not, check the power supply connections to the unit (see page 4).
• No output signal or poor quality signal — Check the integrity of the cabling to output 1 (Local Monitor) and ensure that output 1 is connected to the distribution amplifier before powering on the source device.

If the source device cannot communicate with output 1 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.

- No output signal or poor quality signal — Check the input and output cabling (page 3). DVI signals run at very high frequency and poor connections can cause degradation or loss of the signal, or jitter. To avoid this:

• Use only cable that is designed for DVI signals.
- Limit or avoid the use of adapters.

- Display device shows a flashing black or blue screen, snow or other distortion — A device that is not HDCP compliant may be receiving HDCP-encrypted signals.

The DVI DA2 and DVI DA4 are not High-Bandwidth Digital Content Protection (HDCP) compliant. They will pass HDCP-encrypted signals only to the local output device.

- Signal on local monitor but not on other displays — Check that all output devices (monitors or projectors) can handle resolutions equal to or greater than that of the local monitor.

Mounting

Attach the four provided rubber feet to the bottom of the unit and place it in any convenient location.
