1. EMX-DVI Windows™ Software Installation
1.1. General
The EMX-DVI graphical user interface (GUI) is a software-based solution
capable of configuring any setting on one or more EMX-DVI devices connected
to the Windows PC via a valid USB connection(s).
All of the device features, and more, are accessible from the GUI. EDID files
can be exported or imported. The device is also capable of writing custom
EDID data back to compatible display devices.
1.2. Installation Prerequisites
A PC with Windows XP™ OS or later
USB port
Microsoft™ .NET Framework 2.0 or later (most recent OS including Windows 7
and 8 typically include this and no action is required). 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 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 VR-DVI software installation has completed, either
click the desktop icon or navigate the Start Menu to
Start -> Programs -> Hall Research -> EMX-DVI Extender

User’s Manual
2. Using the Software
2.1. General
In most installations the use of the software is not needed as most functions
can be performed using the push-buttons as described in the users manual.
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.
You can connect more than one VR-DVI to the PC (using several USB ports of
the PC). The same instance of the software detects all connected devices and
allows control from the same interface.
2.2. USB Device Detection
The EMX-DVI software uses standard Windows® drivers to automatically
configure the USB port after connection and does not require any special USB
drivers to be installed.
The first time you connect the extender to the PC, you may experience a short
delay and a windows notification pop-up message may be shown.
This detection and auto installation only occurs once. Thereafter, reconnected
devices are detected with no delay or message.
2
2.2.1. The software scans the EMX-DVI settings continuously in real time, so
all changes are immediately reflected on the screen.
2.2.2. If no EMX-DVI device is attached to the system,
the on-screen fields are disabled (grayed out)
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.

2.6. CONTROLS
VIDEO EDID
Clicking these controls selects to either PASS-THRU or

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.

2.7. STATUS
Video Input
Emulate
Indicates the system is using the internally stored EDID. In
this mode the HPD to the source is asserted since the
source should be able to read valid EDID from the EMX-DVI.
Pass-Thru
Indicates the system is using the connected SINK EDID. If nothing is
connected to the output, then the EMX-DVI will not assert its HDP to the
source. The color of the “Cycle HPD” button (under “Misc”) indicates the state
of HPD.
DVI LINK
Dual Link
Indicates Dual Link operation enabled
Single Link
Indicates Single Link operation enabled
Video Output
Connected or Disconnected
Indicates the state of the device connected to the EMX-DVI
OUTPUT. When a display is detected the button will be
green and the word Connected will be shown next to it. When no display is
detected (or the display is not sending an HPD signal), then the indicator on
the screen changes to a dark red color and the word Disconnected will be
shown next to it.

2.8. EDID Data Display
The data shown in the EDID table is periodically
scanned to ensure that the checksums for each
block are 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.
