DVI DA Plus Series • Setup Guide

Overview

These instructions provide a quick setup guide for the Extron DVI DA Plus Series distribution ampliﬁers. Installation and

service must be performed only by experienced installers. More complete instructions can be found in the DVI DA Plus Series

User Guide, which can be found online at www.extron.com.

Installation

Mounting

Install the distribution ampliﬁer on a desk, under a desk, or in a rack.

DVI Cable Connections

A typical application is shown in the ﬁgure at right. Connect these

cables, but do not power on the equipment yet:

zConnect a DVI cable from the Input connector to the video

source device.

zConnect aDVI cables from the distribution ampliﬁer to the

desired display devices.

Power Cable Connections

Connect the 12 VDC power supply to the power receptacle of the unit. The ﬁgure below shows the 1 A power supply for the

DVI DA4 Plus. The DVI DA6 Plus and DVI DA8 Plus require a 3 A power supply.

CAUTION: See the Caution in the “Power Input” section of

the DVI DA Plus Series User Guide, for important

information about power supplies.

is critical. The ideal length is 3/16 inches (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.

Applying Power

In the following order:

1. Power on the display devices.

2. Power on the distribution ampliﬁer.

3. Power on the source input device.

EDID Minder®

The Extron EDID Minder feature maintains continuous EDID (Extended Display Identiﬁcation Data) communication with

the attached source and ensures that the DVI source powers up correctly and maintains a proper video output, even if the

display is off or when a new monitor is connected to the output.

When the distribution ampliﬁer is powered on, it automatically scans all detectable outputs, selects the device with the

lowest native resolution and passes the EDID information of that device to the input device. If no output displays are

connected, the distribution ampliﬁer provides the EDID information stored from the last display to which it was connected.

If no output device has previously been connected to the unit, or the unit has been set to the factory default, it uses the

factory default resolution (1024x768 @ 60 Hz).

Disabling the EDID Minder

Some applications require that the EDID Minder feature is disabled for speciﬁc outputs or are ignored during the automatic

scanning process. To prevent EDID being read from speciﬁc outputs:

1. Remove and keep the screws holding the cover to the base (seven screws for the DVI DA4 Plus, ten screws for the

DVI DA6 Plus and DVI DA8 Plus). Save the screws and set aside the cover.

2. Check the part number of the printed circuit board (outlined in the ﬁgure above left). The boards must have a part

number of 20-1496-01LF and higher (DVI DA4 Plus) or 20-1497-01LF and higher (DVI DA6 Plus or DVI DA8 Plus).

NOTE: If the part number of the board is lower than these values, you cannot deactivate the EDID Minder on your

model. Replace the cover as described in step 5.

3. Locate the EDID Minder Inactivation DIP switches. The DVI DA4 Plus has a single bank of four switches (see the ﬁgure

above left). Each switch regulates the correspondingly numbered output (1-4).

The DVI DA6 Plus and DVI DA8 Plus have two banks of four switches (see the ﬁgure above right). In bank 1, each switch

regulates the correspondingly numbered output (1-4). In bank 2, switches 1 and 2 correspond to outputs 5 and 6 for the

DVI DA6 Plus; switches 1-4 correspond to outputs 5-8 for the DVI DA8 Plus.

4. By default the switches are in the off/down position, allowing the EDID information to be read from the corresponding

output. To deactivate EDID Minder for one or more outputs, move the switch for that output to the on/up position.

5. Replace the cover, using the screws that were removed in step 1.

EDID Lock and Pre-emphasis

By default, EDID information stored at the input is lost when the unit goes through a power cycle or a new output display is

connected to the device. EDID Lock maintains speciﬁc EDID information so that it is not lost after these events.

Pre-emphasis compensates for poor signals delivered to output devices.

To enable EDID Lock or Pre-emphasis:

1. Remove the cover and locate the part numbers as described in steps 1 and 2 of the previous section.

2. Locate the EDID Lock and Pre-emphasis DIP switches (outlined in the ﬁgure above left). For all three models, the

EDID Lock DIP switch is labeled EDID Mode; the Pre-emphasis DIP switch is labeled Preemph.

3. By default, the EDID Mode and Pre-emphasis DIP switches are in the down (disabled) position. To enable either feature,

toggle the appropriate switch to the up position.

NOTE: Before enabling the EDID Lock feature, be sure the desired EDID is currently being used.

4. Replace the cover, using the screws that were removed in step 1.
