Introduction This guide describes the function, installation, and operation of the Extron HDMI DA2 distribution amplifier. Unless otherwise stated, the terms “distribution amplifier” or “DA” refer to the HDMI DA2. This section provides the following information: zz About the HDMI DA2 zz HDMI DA2 Features zz HDMI DA2 Application Diagram About the HDMI DA2 The Extron HDMI DA2 distribution amplifier distributes one HDMI input signal to two outputs simultaneously.
Output Compatibility Correction — The HDMI DA2 monitors the EDID of each connected display to ensure it is compatible with the current input signal. The following adjustments are made for each output independently: zz Interface format: If the connected display is DVI and the input signal is HDMI, the signal is reformatted to DVI. If the output is HDMI and the input is DVI, no reformatting is needed because HDMI is backwards compatible with DVI.
Installation This section of the guide describes the following topics concerned with the installation and setup of the HDMI DA2 distribution amplifier. zz Installation Overview zz Rear Panel Features zz Connecting the Power Supply zz Connecting the Input Source zz Connecting Output Displays zz Wiring for RS-232 Control zz Connecting to the USB Port Installation Overview To install and set up the HDMI DA2, follow these instructions: 1. Mount the HDMI DA2 in a suitable location (see page 25). 2.
Connecting the Power Supply Connect the provided 12 VDC, 1 A power supply to the HDMI DA2 by following these instructions: WARNING: Remove power before wiring. The two power cord wires must be kept separate while the power supply is plugged in. 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.
Connecting the Input Source Use an HDMI cable to connect the input source to the female HDMI socket on the rear panel (b in figure 2 on page 3). The connectors are fully HDCP compliant. With cables up to 25 feet (7.6 m) they support resolutions of up to 1080p @ 60 Hz with 12-bit color. With cables up to 50 feet (15.2 m) they support 1080p or 1920x1200 @ 60 Hz with 8-bit color.
If the source requires HDCP encryption and the display is not HDCP compliant, that output channel outputs a green screen. Both outputs carry +5 VDC and up to 250 mA on pin 18, regulated by a current limiting circuit. Wiring for RS-232 Control (Optional) RS-232 communication between the HDMI DA2 and a host PC can be used to update firmware or configure the distribution amplifier using SIS commands (see Command and Response Table for SIS Commands on page 17).
Connecting to the USB Port The mini Type B USB port is located on the HDMI DA2 front panel (b in figure 7 on page 10). It can be used to connect the distribution amplifier to a host computer to update firmware or for configuration using SIS commands. 1. Connect a USB A to mini B cable between the USB Config port on the front panel of the HDMI DA2 and the USB port of the PC.
Figure 5. Found New Hardware Wizard Welcome Screen zz Select Yes, this time only to connect the PC to Windows Update only this one time. zz Select Yes, now, and every time I connect a device to automatically connect to Windows Update every time the HDMI DA2 connects to this USB port. zz Select No, not this time if you do not want to connect to Windows Update (for example, if the driver is already on the PC). 3. Click Next. The next screen of the Wizard opens: Figure 6.
5. When the Completed screen appears, click Finish to close the wizard. NOTE: The wizard appears only on the first occasion you connect the HDMI DA2 to that USB port. The wizard reappears if you connect the HDMI DA2 to a different USB port or if you connect a different piece of equipment, requiring a different driver, to the same USB port. 6. Configure the HDMI DA2 as required (see Operation on page 10).
Operation This section of the manual provides information on: zz HDMI DA2 Front Panel Features zz EDID Minder HDMI DA2 Front Panel Features 3 CONFIG OUTPUTS 1 2 INPUT SIGNAL EDID HDCP HDMI DA2 1 2 Figure 7. a b c d e 4 5 HDMI DA2 Front Panel Power status LED USB Config port Signal LEDs HDCP LEDs EDID LED Power Status LED The power status LED lights green when power is applied to the unit. USB Config Port The USB Config port is used for SIS configuration, monitoring, and firmware updates.
Signal Status LEDs Input Signal LED The input signal LED lights green when a TMDS signal is detected on the HDMI input. If the source requires HDCP encryption, this LED may light only after the HDCP has been authenticated. Output Signal LEDs There are two output signal LEDs, one for output 1 and the other for output 2. The LEDs light green when a TMDS signal is being transmitted to a sink device on the corresponding HDMI output.
EDID Minder EDID Minder ensures that the connected source sees the EDID of a display, even if a display is not connected. Depending on the EDID mode selected (by SIS command), the EDID of a connected display can be stored automatically, or the user can manually select from the table of factory loaded EDID files. This EDID is stored on an EEPROM located at the HDMI input. By default, the HDMI DA2 is configured to store EDID from the display connected to output 1 automatically.

Footnotes for the EDID table (see page 13) The following footnotes apply to the EDID table on the previous page: 1 Rate Type zz PC: These are primarily VESA standard computer rates, based on the most commonly used native resolutions. They are designed to be used with computer sources. zz HDTV: These are video rates standardized by SMPTE and CEA. They are designed to be used with video and computer sources. 2 Video Format zz DVI: These are 128-byte EDID files, which specify a DVI sink.
SIS Commands This section provides information about the SIS commands that are used to configure the HDMI DA2. The following topics are discussed: zz Introduction to SIS zz Symbols Used in this Guide zz Command and Response Table for SIS Commands Introduction to SIS The HDMI DA2 accepts SIS commands from a host device such as a computer running the Extron DataViewer utility or other control system.
Symbols Used in this Guide When programming in the field, certain characters are most conveniently represented by their hexadecimal rather than their ASCII values. The table below shows the hexadecimal equivalent of each ASCII character: ASCII to HEX Conversion Table Space . Table 2.
