Description
The D/2 DA4 DVI Direct Digital Distribution Amplifier (DA) accepts a
Digital Visual Interface (DVI) signal or a Digital Flat Panel (DFP) signal
(with a DFP-to-DVI adapter) from a computer or other device that
outputs digital video. The D/2 DA4 DVI outputs four independently
buffered signals. The D/2 DA4 DVI is rack mountable and has an
internal switching power supply.
Installation
1. Power off the computer and its local monitor.
2. For optional rack mounting, mount the D/2 DA4 DVI on the left
or right side of a 19" 1U Universal Rack Shelf (Extron
part #60-190-01) (figure 1).

remove them.
b. Mount the D/2 DA4 DVI on the rack shelf, using two
4-40 x 1/8 screws in opposite (diagonal) corners to secure the
case to the shelf.
3. Connect the D/2 DA4 DVI input cable (figure 2) to the DVI video
output port the of the computer (figure 3).

4. Connect the computer monitor to the Local Monitor output of the
D/2 DA4 DVI.
The maximum permissible length of the DVI input and output
cables is 16.4 feet (5 meters). Ensure that the cables do not exceed
the maximum permissible length, otherwise images may be
distorted or missing. Extron does not guarantee signal integrity
beyond 16.4 feet.

Operation
Troubleshooting Specifications
Operation
After the D/2 DA4 DVI and its connected devices are powered up, the
system is fully operational. If any problems are encountered, verify that
the cables are routed and connected properly, and that all display
devices have identical resolutions and refresh rates.
The direct digital video output is tailored for a specific monitor
resolution and refresh rate. Ensure that all display devices have
identical resolutions and refresh rates, otherwise images may be
distorted or missing.
Ensure that the computer and primary monitor are connected to
the D/2 DA4 DVI, and the D/2 DA4 DVI and monitor have power
applied, before applying power to the computer. If the other
devices are not turned on before the computer is, the image will
not appear.

DVI/DFP signals run at a very high frequency and are especially
susceptible to bad video connections, too many adapters, or too long
cables. To avoid the loss of an image or image jitter, follow these
guidelines:
• Do not exceed 16.4 feet (5 meters) on the output of the DA.
• Use only cable designed for DVI signals.
• Limit or avoid the use of adapters.
• Use only approved DVI/DFP connectors.
