Introduction About this Guide This user guide describes the installation, operation, and specifications of the Extron® DVI DA4 Plus, DVI DA6 Plus, and DVI DA8 Plus Distribution Amplifiers. Unless stated otherwise, all references to the “distribution amplifier,” “DA,” or “DVI DA Plus Series” in this guide refer to the features or operation of all three models.
Features EDID Minder — The EDID Minder maintains continuous EDID (Extended Display Identification Data) communication with the attached source to ensure that the DVI source powers up correctly and maintains a proper video output, even if the display is off. EDID Lock — The last recorded EDID is saved to the input and used after a power cycle or after displays have been changed. The EDID presented to the input is not affected by power cycles or changing the output displays (even with hot-plug changes).
Installation This section describes: • Installation Overview • Rear Panel Features Installation Overview All three distribution amplifiers can be mounted on tabletops, under furniture, and in racks by following these steps: 1. Ensure that the input sources, the distribution amplifier and the output displays are all turned off and all power sources and signal cables are disconnected. 2. Mount the unit as described in “Mounting” on page 15. 3. Connect the cables (see “Rear Panel Features” on page 4). 4.
Rear Panel Features The rear panels for the DVI DA4 Plus (top panel), the DVI DA6 Plus (middle panel), and DVI DA8 Plus (bottom panel) are shown below.

CAUTION: These products are intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS”, rated 12 VDC, maximum 1.0 A (DVI DA4 Plus) or maximum 3.0 A (DVI DA6 Plus and DVI DA8 Plus). 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.
DVI Connector Pin Assignments The illustration below shows the pin assignments for the DVI-I connectors. See the note under input connectors for information about DVI signal compatibility. NOTE: The DVI DA Plus series distribution amplifiers are not High-Bandwidth Digital Content Protection (HDCP) compliant.
Operation This section of the guide provides information on: • Front Panel Features • Operation • EDID Minder • Disabling the EDID Minder • Troubleshooting Front Panel Features Figure 4 shows the front panel for the DVI DA4 Plus (top) and the front panel for the DVI DA6 Plus/DVI DA8 Plus, which are identical (bottom).

EDID Minder When a DVI video source boots up, it normally communicates with the output device using the bidirectional Extended Display Identification Data (EDID) communication protocol. The source device then produces a signal with a resolution that is compatible with the output device.
3. Locate the DIP switches. There is a single bank of four switches for the DVI DA4 Plus (outlined in red in figure 5). Each switch regulates the correspondingly numbered output (1-4). Rear Panel Part Number EDID Lock and Pre-emphasis DIP Switches EDID Minder Inactivation DIP Switches Figure 5. Printed Circuit Board for the DVI DA4 Plus There are two banks of four switches for the DVI DA6 Plus (see figure 6) and the DVI DA8 Plus.
EDID Lock Some applications require the distribution amplifier to maintain specific EDID information. This information could be lost after power is cycled off and on or when a new output display is connected to the DVI DA Plus. By default the EDID Lock mode DIP switch is set to “Off”. In this position, when the distribution amplifier is powered off, the EDID information that was being used is erased.
4. By default, the EDID Mode DIP switch is in the down (disabled) position, allowing for normal operation. To enable the EDID Lock feature, toggle the switch to the up position. NOTE: Before enabling the EDID Lock feature, be sure the desired EDID is currently being used. 5. Replace the cover, using the screws that were removed in step 1. Pre-emphasis Pre-emphasis compensates for long cable runs, distortion, and pixelation on the distribution amplifier outputs. To enable pre-emphasis: 1.
Troubleshooting No output signal — Check that the front panel LED is lit (amber shows that the unit is receiving power, green shows that it is also receiving an input signal). If LED is not lit, check the power supply (page 4) and the video input connections (see page 5). No output signal or poor quality signal — Check the integrity of the cabling from the source device to the distribution amplifier and from the distribution amplifier to each of the display devices.

Extron® Warranty Extron Electronics warrants this product against defects in materials and workmanship for a period of three years from the date of purchase.
Installation Checklist Ensure that the input sources, the distribution amplifier and the output displays are all turned off and all power sources and signal cables are disconnected. Mount the unit as described in “Mounting”, (see page 15). Connect the cables (see “Rear Panel Features”, on page 4). If required, configure the internal DIP switches to disable EDID (see page 8) from certain outputs, to activate the EDID Lock mode (see page 10), or to enable pre-emphasis (see page 11).
