1. EMX-AMP Windows™ Software Installation
1.1. General
The EMX-AMP is controllable via free Windows® based software available from the
Hall Research website.. All of the device features, and more, are accessible and
controllable from the GUI.
References in this manual to the model EMX-AMP also apply to LAN enabled model
EMX-I-AMP.
1.2. Software Installation Prerequisites
•A PC with Windows XP® OS or later
•USB port
•Microsoft® .NET Framework 2.0 or later (most recent OS including
Windows 8 and later include this software and no action is required). If the
.NET Framework 2.0 or later is not installed on your PC, the Microsoft™
website has free downloads available.
1.3. Software Installation
If an earlier version of this particular software was previously installed,
UNINSTALL the program first from either the Add/Remove Programs section of
the control panel or by running the previous installation’s SETUP.EXE and
selecting “remove application”.
•Install the software by executing the SETUP.EXE program from the
installation source directory
•Accept the default settings, but if you want to specify a particular
installation directory other than the default, you may do so.
•Once the EMX-AMP software installation has completed, either click the
desktop icon or navigate the Start Menu to
Start -> Programs -> Hall Research -> EMX-AMP Amplifier

2. Using the Software
2.1. General
In most installations the use of the
software GUI is not required as most
functions can be performed using the
front panel buttons on the product.
You can use the software to
import/export EDID files from the
device. Custom EDID data can also be
written to devices connected to the
output if they support that function.
It is possible to connect more than one EMX-AMP to the PC (using several
USB ports of the PC). The same software GUI detects all connected devices
and allows control from the same application.
2.2. USB Device Detection
The EMX-AMP software uses standard Windows® drivers, which automatically
configure the USB port after connection and do not require the installation of
any special USB drivers.
The first time you connect the EMX-AMP to the PC, you may experience a
short delay and a windows notification pop-up message may be shown.
2.2.1. The software GUI scans the EMX-AMP
settings continuously in real time, so all
device changes are immediately reflected
on the software GUI.
2.2.2. If no EMX-AMP device is attached to the
system, the on-screen fields are disabled
(grayed out).
2.2.3. Only one instance of the software GUI can run at
a time. Executing the application more than once
will result in a warning message.
The new device detection and driver auto installation typically only occurs
once. Thereafter, reconnected devices are detected with no delay or
message.

Function
The Function control field shows ON or OFF.
This field indicates which is being displayed or
configured.
Protocol
The Protocol control field shows either ‘Serial’ or ‘Delay’. This pertains to
whether the user is entering an RS232 command or a Time Delay into the
currently set ‘Function’.
Command (Protocol set for Serial)
The Command control field is where the user enters the desired RS232
string.
The RS232 values can be entered as ASCII text and/or hex byte values
formatted in a &hXX format.
Any extra spaces or other characters entered are transmitted.
Where “XX” is the desired HEX byte value.
Any character from 0 to 0xFF can be entered in this format.
Delay (sec) (Protocol set for Delay)
The Delay (sec) control field is where the
user enters the desired time delay in
seconds. The limit is from 1 to 6 seconds.
INSERT
The INSERT control is clicked to append the current ‘Serial’COMMAND or
TIME DELAY into the existing command.
The new command (either Serial or Delay) is appended to any existing
command and is displayed in the window.

the device to automatically send the pre-programmed RS232 strings
(ON or OFF) when a specific event occurs.
oNONE – NO action will occur
o+5 – When +5 vDC is received on the HDMI Input, the ON string
will be sent from Serial Port #2. When the +5 vDC is no longer
received, the OFF string will be sent from Serial Port #2.
oVideo – When video is received on the HDMI Input, the ON string
will be sent from Serial Port #2. When the video is no longer
received and after an optional time delay, the OFF string will be
sent from Serial Port #2.
oContact - When terminals CCW and GND are connected
(shorted), the ON string will be sent from Serial Port #2. When
CCW and GND are NOT connected (open), the OFF string will be
sent from Serial Port #2.
Video Auto Off Delay (min)
The Video Auto Off Delay (min) control field shows the device current Video
time delay value as well as being able to set that value. Factory Default is 0.
•When 0 and ‘Auto Detection’ is set for ‘Video’ the OFF string will be
sent immediately from Serial Port #2.
•When set to any value between 1 and 240 minutes, the OFF string will
be sent from Serial Port #2 after the delay has elapsed.
•NOTE, the actual time elapsed before the OFF string is sent from
Serial Port #2 can be +/- 5% of the time entered.

EDID Tab
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-AMP.
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.
EDID Data Display
The data shown in the EDID table is continually
scanned to ensure that the checksums for each
block is valid.
When wrong checksums are detected, the
invalid checksum byte is highlighted in RED.
If an action is performed that affects the EDID such as initiating a "learn"
process, The checksum field might momentarily flash ‘RED’ during the this
process, but should go back to normal once the entire table is updated.
NOTE
You cannot “LEARN” an EDID that has an invalid checksum. If you try to learn an EDID that has a
checksum error, the POWER and MUTE Button LEDs on the unit will alternately flash 5 times to
indicate the error.
No other checks are performed on the EDID to determine that it is valid per the EDID standard.
However, the GUI software can import and upload to the EMX-AMP, EDID’s that contain invalid
checksum for testing purposes.

Ducking
Threshold
The Threshold control shows the device
3.5mm LINE IN audio line-level
threshold. Factory default is 100%.
(Technically, this is ‘OFF’ since 100%
cannot be exceeded)
If the 3.5mm LINE IN audio level exceeds this amount, the HDMI/ARC volume
will be reduced by the given ‘Ratio’.
Ratio
The Ratio control shows the device ‘Ducking’ threshold ratio. This is the
percentage the HDMI/ARC volume is reduced when the ‘Threshold’ is
exceeded. Factory Default is 50%.
PageSense
Threshold
The Threshold control shows the device Paging Sensor voltage threshold.
Factory default is 100%. (Technically, this is ‘OFF’ since 100% cannot be
exceeded)
If the Paging Sensor input voltage exceeds this amount, the output volume will
be muted.
Note
The graphical displays only update if the Ducking or PageSense ‘Threshold’ level has actually
tripped.
To see a live display of the incoming signal, temporarily set the ‘Threshold’ level to a value
lower than the incoming signal.
Example
When the ducking threshold is exceeded, whatever volume level the HDMI/ARC is
currently set for will be reduced by the ‘Ratio’.
If the volume level is currently 75% and the ‘Ratio’ is set for 50%, when the Ducking is in
effect, the output volume level will be set for 75% * 50% = 37.5%.
