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:

About the HDMI DA2
The Extron HDMI DA2 distribution amplifier distributes one HDMI input signal to two outputs
simultaneously. It is fully High-bandwidth Digital Content Protection (HDCP) compliant.
The HDMI DA2 supports data rates up to 6.75 Gbps (2.25 Gbps per color) with up to 12-bit
deep color and uses the EDID Minder® feature for EDID management.
The automatic output compatibility correction feature scans each output device to ensure
that the output signal is compatible with the audio capabilities, color depth, and format
requirements of the device. Each output is adjusted independently.
HDMI DA2 Features
HDMI signal distribution — The HDMI DA2 accepts one HDMI input and provides two
HDMI outputs.
Key Minder® — Key Minder authenticates and maintains continuous HDCP encryption
between the input and output devices to enable simultaneous distribution of a single encrypted
source to two displays.
Signal Status LEDs — Front panel signal status LEDs indicate TMDS and HDCP status for the
input and each output.
EDID Minder — This feature allows the user to choose from a list of 46 factory-loaded EDID
files, to import EDID information from either of the display devices, or to import and save
an EDID file from a PC. EDID Minder has two modes of operation that can be selected and
configured using SIS commands:
z
Automatic: EDID from the display connected to output 1 is read and stored at the input
automatically (default mode). Use SIS commands to read and store EDID from output 2.
z
User assigned: EDID can be manually assigned from the internal factory EDID table,
which contains 46 unique EDID files categorized by native resolution and audio support.
Additionally, there are four user slots available to store and recall EDID from connected
displays.

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:
z
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.
z
Video color bit depth: If the connected output device does not support the color
bit depth of the input signal, it is truncated down to the next level that is supported
(12-bit > 10-bit > 8-bit). The signal can be forced to always truncate to 8-bit via Simple
Instruction Set (SIS™) commands, disabling deep color.
z
Audio: If the connected output device does not support the audio format of the input
signal, audio is muted.
NOTE: These adjustments do not affect the actual video or audio data (there is no video
scaling or audio decoding or mixing). It is up to the user or installer to ensure that
the connected display device is compatible with the video resolution of the input
signal.
Easy mounting options — The HDMI DA2 is a quarter rack wide, 1 inch high, and 3 inches
deep, which allows the unit to be conveniently mounted in a rack or under furniture.

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.
Input HDCP LED
The Input HDCP LED lights green when the source device requires HDCP encryption and it has
been authenticated with the HDMI input.
Output HDCP LEDs
There are two output HDCP LEDs, one for output 1 and the other for output 2. The LEDs light
green when HDCP has been authenticated between the HDMI output and the corresponding
sink device. This happens when the source device requires HDCP encryption and it has already
been authenticated on the HDMI input.
The LEDs do not light if the source does not require HDCP encryption or if the sink is not HDCP
compliant. If HDCP encryption is required but the sink device is not HDCP compliant, that
output channel outputs a green screen.
EDID LED
The EDID LED lights green when the EDID is successfully stored from the selected output device
(output 1 by default).
The LED lights amber if the internal, factory-installed EDID is used or if the EDID was not
successfully stored.

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. The unit reverts to this configuration after a factory reset.
Automatic Mode
In automatic mode, the HDMI DA2 automatically reads and stores EDID from output 1 (a
different output can be chosen using SIS commands). This EDID is retained until a different
display is connected or the unit is power-cycled. If no display is connected when the unit is
powered on, then a factory default EDID (720p @ 60 Hz, 2-Ch audio) is present.
User Assigned Mode
In user assigned mode, the user can select from 46 factory loaded EDID files, each catagorized
by rate type (PC or HDTV), video format (DVI or HDMI), audio type (2-Ch or Multi-Ch), and
native resolution. The unit retains this setting after a power cycle.
Additionally, four user-loaded slots are available to save the EDID of any connected display.
EDIDs saved to these slots are retained after a power cycle. Upon a factory reset, these EDIDs
revert to the factory default (720p @ 60 Hz, 2-Ch audio).
A table showing the factory loaded EDID options is shown on the following page. The EDID
memory location is labelled X$for consistency with the value in the SIS commands.

SIS Commands
This section provides information about the SIS commands that are used to configure the
HDMI DA2. The following topics are discussed:
z

z
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. The host device can be connected
to the 3-pin captive screw connector on the rear panel or to the config port on the front
panel. To connect to the config port, use the optional Extron 9-pin D female to 2.5 mm TRS
Configuration cable (part number 70-335-01).
The protocol is 9600 baud, 8 data bit, 1 stop bit, and no parity.
NOTES: • The wiring in the RS-232 cables crosses over so that the HDMI DA2 transmit (Tx)
wire connects with the control device receive (Rx) and vice versa.
• Only one serial port can be used at a time. If the front port is in use, the rear
captive screw connector must be disconnected from the computer or other
control device. Likewise, if the captive screw port is in use, the config port on the
front panel must be disconnected from the computer or other control device.
SIS commands consist of strings (one or more characters per command field). Unless otherwise
stated, upper and lower case characters can be used interchangeably. Commands do not
require any special characters to begin or end the command string. Each response from the
HDMI DA2 ends with a carriage return and a line feed (CR/LF = ]), which signals the end of
the response character string.
When the HDMI DA2 is first switched on, it sends the message:
(c)Copyright2012,ExtronElectronicsHDMIDASeries,Vx.xx,
60‑997‑01]where 60‑997‑01is the catalog part number and Vx.xxis the firmware
version number.

Rack Mounting
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of
these products in a rack:
1. Elevated operating ambient temperature — If the unit is installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient temperature (Tma: +122 °F, +50 °C)
specified by Extron.
2. Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Consider the equipment nameplate ratings when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections to
the branch circuit (such as the use of power strips).
Rack Mounting Procedure
The unit can be mounted on any of these optional rack systems, including:
