1. EMX-HD-AUD Windows™ Software Installation
1.1. General
The EMX-HD-AUD graphical user interface (GUI) is a software-based solution
capable of configuring any setting on one or more EMX-HD-AUD devices
connected to the Windows PC via a valid USB connection(s).
1.2. Installation Prerequisites
A compatible PC with Windows XP™ or later operating system with a USB
connection is required.
• Microsoft™ .NET Framework 2.0 or later.
• If .NET Framework 2.0 or later is not installed on your PC, the
Microsoft™ website has free downloads available.
1.3. Software Installation
• If software previously installed, UNINSTALL the program first from either
the Add/Remove Programs section of the control panel or by run the
previous installation SETUP.EXE and select “remove application”.
•
Install the software by executing the SETUP.EXE program from the
installation source directory
•
The typical user should be able to accept all the default settings; but the
default installation directory can change if desired.
Once the EMX-HD-AUD software installation has completed,
either click the desktop icon or navigate the Start Menu to…
Start -> Programs -> Hall Research -> EMX-HD-AUD Audio Extractor

2. Using the Software
2.1.
General
Most EMX-HD-AUD installations are setup solely from the devices front panel
push buttons.
The GUI software can control multiple devices from one computer, or used to
import/export EDID files to/from the device. Custom EDID data can also be
written to compatible output devices.
2.2. USB Device Detection
The EMX-HD-AUD AUDIO EXTRACTOR & EDID MGR GUI software
automatically configures as a HID (Human Interface Device) and does not
require any USB drivers installed by the end-user.
Once connected to a valid USB port, the Windows™ system will automatically
detect and identify the appropriate USB driver. There may be short delay while
this process occurs and a windows notification message may be shown.
This detection and driver installation only occurs when the EMX-HD-AUD
connects for the first time. Afterwards, reconnected devices
automatically configure themselves.
2.2.1. The GUI software scans the
EMX-HD-AUD settings at a
rate of 10 times per second to
provide quick response times
to the user.
2.2.2. The GUI software on-screen
fields are disabled until a valid
EMX-HD-AUD device is
attached to the system.
2.2.3. Only one instance of the GUI program can run at
a time. Executing the application more than once
will result in an error message.

2.3.3. TOOLS
Factory Defaults
Restore the device to factory default settings.
The user must confirm the action.
Import EDID
Import an EDID (256-byte binary or XML file) into the unit.
Export EDID
Save the current EDID as a 256-byte binary file
This file can be edited using third party software and reloaded using the
‘Import EDID’ tool selection.
Write EDID
Writes the current 256-byte EDID to the current
output device. This option is not available on
systems with older firmware.
The user must confirm the action and take all necessary precautions to
prevent loss of data. Hall Research is not responsible for any damage that
may occur from the user attempting to modify the EDID.
Firmware Update
Allows users to field upgrade the device application firmware. Application
firmware that does not support this function will disable this option. Only
valid firmware files can be uploaded into the EMX-HD-AUD.

User’s Manual
2.3.5. ABOUT
Displays screen with software versions,
website link, legal disclaimer and copyright
information. The Serial # information
displayed is a time/date stamp referenced to
GMT (Greenwich Mean Time) and has no
reference to the serial number sticker on the actual device.
2.4. Device Name
Assigns a descriptive name to the EMX-HD-AUD device that
is a maximum 8 characters long. The user is not allowed to
change the device name with multiple devices connected.
The FACTORY DEFAULT name is USBDEVHR.
2.5. Status Bar
The bottom bar of the screen shows the current USB status as follows:
“Scanning for Hardware…”
The GUI software is looking for EMX-HD-AUD devices.
Screen controls disable until a valid EMX-HD-AUD device
attached
“Connected – XX”
Where XX is the number of EMX-HD-AUD devices connected to the
PC.
2.6. CONTROLS
VIDEO EDID
Clicking these controls selects to either PASS-THRU or
EMULATE the EDID.
PASS-THRU uses the SINK EDID while EMULATE uses the
internal EDID saved in the EMX-HD-AUD.
PASS-THRU is the FACTORY DEFAULT setting.
Learn EDID
Clicking this control will extract the EDID from device
connected to the output connector and save it in the unit.
The user must confirm the action.

MODEL EMX-HD-AUD AUDIO EXTRACTOR & EDID MGR
AUDIO EDID
Clicking these controls selects either PASS-THRU, 2 CHN or
MULTI modes
MULTI – EDID from SINK is set for LPCM, DTS and Dolby
audio with multiple speakers.
This is the FACTORY DEFAULT setting.
2 CHN – EDID from SINK is set for 2 channel LPCM audio with 2 speakers.
PASS-THRU – EDID from SINK is used.
Misc
Toggle HPD
Clicking this control sends a 500 mS Hot Plug Detect
signal to the video source. This indicator is ‘filled’ when
the source is connected.
Mute HDMI
Clicking this control mutes the HDMI Audio.
FACTORY DEFAULT is not muted.
Mute LR/TOS
Clicking this control mutes the 3.5mm L/R and TOSLINK Audio.
FACTORY DEFAULT is not muted.
Disable/Enable DDC
Enabling this control will turn off the DDC communication with the SOURCE
device. The SOURCE will receive no response from any HDMI or EDID
requests. This effectively disables the SOURCE from displaying HDCP content.
FACTORY DEFAULT is not enabled (HDCP and EDID acceptable).
2.7. STATUS
Video Input
No Video
Indicates the system is not receiving an INPUT video
signal.
HDCP On
Indicates video received has HDCP Encryption enabled.
HDCP Off
Indicates video received has HDCP Encryption disabled.

User’s Manual
Audio Input
No Audio
Indicates no audio received (DVI mode)
Multi-Channel
Indicates HDMI audio received is not LPCM format.
2 Chn
Indicates HDMI audio received is LPCM format.
Video Output
Connected or Disconnected
Indicates the state of the device connected to the EMXHD-AUD OUTPUT.
2.8. EDID Data Display
The data shown in the EDID table is
periodically scanned to ensure that the
checksums for each block is valid.
When an invalid checksum is detected,
that byte (at the end of 128 bytes) is
highlighted in RED.
This is so invalid EDID checksum values can be easily identified
by the end user display devices that can cause connectivity
problems.
If the checksum bytes in the GUI display continually show RED,
the checksum is invalid.
If you perform an action that affects the EDID, it is possible for
the checksum to momentarily show ‘RED’ until the complete
EDID has been updated on the screen.
You can not “LEARN” an EDID that has an invalid checksum
from either the GUI nor from the front panel push buttons.
The GUI interface software WILL let you IMPORT EDID’s that
contain invalid checksum data for testing purposes.
No other checks are performed on the EDID to determine that it
is valid per the EDID standard.

2.9. EDID Mixing
At powerup, the default EDID stored within the device is loaded.
This could be either the factory default or a ‘Learned’ EDID.
If a functioning and valid SINK device is connected to the EMXHD-AUD ‘Output’ connector AND the VIDEO mode is set to
PASS-THRU, the EDID from the SINK will be read and loaded
into memory.
If the SINK EDID read is a simple 128 byte EDID (like a VGA
monitor), a CEA-861 extension block (2nd 128 bytes) will be
added to the EDID with a default native resolution of 480p and
with LPCM 2 channel audio.
If the SINK is disconnected from the EMX-HD-AUD connector,
the internally saved EDID will be presented to the SOURCE
mixed according to the AUDIO settings.
Each time the VIDEO or AUDIO pushbuttons or GUI controls are
pressed, the EDID presented to the SOURCE is as follows:
VIDEO MODE
AUDIO MODE
EDID EFFECT

AUDIO AND CEC ADDRESS MODIFICATION
CEC Address modification consists of taking the SINK or INTERNAL EDID and
modifying the address to insert the EMX-HD-AUD CEC Physical address into the
CEC chain. (The EMX-HD-AUD device does not understand any CEC
commands).
For example:
SINK EDID has CEC address of 0.0.0.0
EDID given to source will show the EMX-HD-AUD as CEC address 1.0.0.0 and
the display still with its original CEC address of 0.0.0.0

2.10.
CEC Physical Addressing
The EMX-HD-AUD automatically adjusts the CEC (consumer
electronic control) physical address of the device based on the
settings of the SINK EDID.
CEC commands are passed through to all downstream devices
without modification.
