1.2. Features
60 meter input cable compensation – Using 22AWG high quality DVI cable, the
input is automatically compensated for up to 60 meter cable length, which extends installation possibilities even on highest HDTV or computer resolutions. In case of lower pixel resolutions, this length can be even higher.
Advanced EDID Management – The user can emulate any EDID on the DA2DVI-
Pro’s input, read out and store any monitor's EDID (attached to Output 1) in 49 internal memory locations, upload and download EDID files using Matrix Control Software.
Supports all HDTV resolutions – 720p, 1080i and 1080p etc. without HDCP
encoding - Unencrypted HDTV signals up to 165 MHz pixel clock frequency regardless of the resolution passed through.
Pixel Accurate Reclocking – (removes jitter and skew caused by long cables)
each output has a clean, jitter free signal, eliminating signal instability and distortion caused by long cables or connector reflections.
Signal Present LED – Valid DVI signal is detected, when signal is applied to DVI
INPUT.
Source and Monitor Connected LEDs – Three LEDs indicate when a DVI source
and display diveces are connected to the DA2DVI-Pro.
Front and rear panel control – EDID Address selection with two decimal rotary
switches and Learn EDID button are available on the front panel. Advanced hardware settings can be made with DIP switch on the rear side of the DA2DVI-Pro.
Software control – Input status, output settings, EDID Management, Terminal
Window and hardware information can be accessed in Lightware Matrix Controller software using a USB connection.
Fiber cable support – Self powered DVI fiber cables using +5V from DVI sources
(VGA cards, etc.) usually consume more than 50 mA, which load is maximum allowed by DVI 1.0 standard. DA2DVI-Pro supports +5V 500 mA constant current output on each DVI OUTPUT to power long distance fiber optical cables.
Universal power adaptor – DA2DVI-Pro is equipped with a universal +5V power
adaptor, which accepts AC voltages from 100 to 240 Volts with 50 or 60 Hz line frequency.
Page 8
Page 8 / 43
1.3. Advanced EDID Management
Each DVI sink (e.g. monitors, projectors, plasma displays, and switcher inputs) must support the EDID data structure. Source BIOS and operating systems are likely to query the sink using DDC2B protocol to determine what pixel formats and interface are supported. DVI standard makes use of EDID data structure for the identification of the monitor type and capabilities. Most DVI sources (VGA cards, set top boxes, etc) will output DVI signal after accepting the connected sink’s EDID information. In case of EDID readout failure or missing EDID the source will not output DVI video signal.
DA2DVI-Pro provides Lightware’s Advanced EDID Management function which helps system integration. The built-in EDID Manager stores and emulates 100 EDID plus the EDID of the display device which is connected to DVI OUTPUT 1. Memory addresses from 01 to 50 are factory presets, while memories from 51 to 99 are user programmable. The DA2DVI-Pro stores the EDID of the monitor or projector connected to DVI OUTPUT 1 in a non-volatile memory.
The EDID emulated on the input can be copied from the DA2DVI-Pro's memory (static EDID emulation) or from the attached monitor (dynamic EDID emulation). For example, the DA2DVI-Pro can be set up to emulate the device, which is connected to DVI OUTPUT 1, and the EDID automatically changes, if the monitor is replaced with another display device (as long as it has a valid EDID).
Info The user is not required to disconnect the DVI cable to change an EDID as
opposed to other manufacturer’s products. EDID can be changed even if source is connected to the input and powered ON.
1.4. Pixel Accurate Reclocking
DA2DVI-Pro reclocks the signal on all outputs using Lightware’s sophisticated Pixel Accurate Reclocking technology. Signal reclocking is an essential important procedure in digital signal transmission. After passing the reclocking circuit, the signal becomes stable and jitter-free, and can be transmitted over more equipment like processors, or event controllers. Without reclocking, sparkles, noise and jaggies can be seen on the image.
The Pixel Accurate Reclocking circuit eliminates the following errors:
Intra-pair skew: skew between the + and - wires within a differential wire pair (e.g.
Data2- and Data2+). It’s caused by different wire lengths or slightly different wire construction (impedance mismatch) in DVI cable. It results in jitter.
Page 9
User’s Manual Rev. 1.3
Page 9 / 43
Inter-pair skew: skew between two differential wire pairs in a cable. It’s caused by
different wire pair lengths or different number of twists in the DVI cable. Too much inter-pair skew results in color shift in the picture or sync loss.
Jitter: signal instability in the time domain. The time difference between
two signal transitions should be a fix value, but noise and other effects cause variations.
Noise: electromagnetic interference between other electronic devices
such as mobile phones, motors, etc. and the DVI cable are coupled onto the signal. Too much noise results in increased jitter.
The Pixel Accurate Reclocking circuit completely regenerates the original video signal and outputs a strong, high-quality digital signal that conforms to the DVI specification.
Page 10
Page 10 / 43
1.5. Fiber Cable powering
As special feature DA2DVI-Pro is able to supply 500 mA current to power fiber optical transmitters like DVI-OPT-TX100 (Pin 14 on both DVI output connectors). Standard DVI outputs or VGA cards supply only 55 mA current on +5V output, thus unable to directly power a fiber optical cable.
Info DA2DVI-Pro does not check if the connected sink (monitor, projector or other
equipment) supports Hotplug or EDID signals but outputs the signal immediately after it has been applied to the input.
1.6. Cascading multiple DA2DVI-Pros
Thanks to the built-in cable equalizer and the Pixel Accurate Reclocking circuit, up to 8 DA2DVI-Pros can be cascaded. This feature is especially useful for digital signage applications. The distance between the display blocks may be up to 60 meters in case of HD 1080p resolution, or even higher for lower pixel numbers or interlaced scan 1080i.
If the display devices have different resolutions, please emulate the EDID of the display that has the lowest resolution, otherwise the displays with higher resolutions may not show the whole image, rescale the image or won’t display an image at all.

is connected to the DVI OUTPUT 1 connector and sends a valid Hot Plug Signal on Pin 16 through the DVI cable.
Monitor 2 hotplug LED Indicates if a display device (or matrix switcher, repeater, etc.)
is connected to the DVI OUTPUT 2 connector and sends a valid Hot Plug Signal on Pin 16 through the DVI cable.
EDID status LED Function 1: displays the firmware version of the device. For
more information, see chapter 2.1.
Function 2: after applying a Hot Plug signal to DVI OUTPUT 1,
this LED indicates that the unit is reading the EDID from the connected display device. If the LED is blinking green then the EDID is valid, if blinking red, then the EDID is invalid or missing.
Function 3: this LED indicates whether the selected EDID is
valid (continuous green = valid, continuous red = invalid or empty memory selected). EDID address selection can be done by front panel rotary switches or Matrix Controller software.
Learn EDID button Stores the EDID of the display device attached to DVI OUTPUT
1 in the selected memory address (51…99). To learn the EDID, select an appropriate address with the rotary switches and press and hold the Learn button for two seconds.
Power LED Indicates if the device is powered on. It does not indicate
whether the device is operating properly.
Address selection The rotary switches select one of 100 addresses. Addresses
1…50 are factory preset and 51…99 are user programmable. Use a flat head screwdriver that fits into the actuator. Avoid use of keys, coins, knives and other sharp objects because they might cause permanent damage to the rotary switches.

2. Operation
2.1. Power
When building an electronic system, make sure that all of the devices are powered down before connecting them. Powered on devices may have dangerous voltage levels that can damage sensitive electronic circuits.
1. After the system is complete, connect the the +5V Power Adaptor to the DA2DVI-Pro. The unit is immediately powered ON.
After the DA2DVI-Pro is initialized, the attached DVI source and monitor(s) can be powered on.
2. After being powered on, the DA2DVI-Pro displays its firmware version using the EDID Status LED.
The following example shows this process for a firmware version of 1.3.7
RED blinks once → Short pause → GREEN blinks three times → Short pause → GREEN blinks seven times → Short pause → The normal function of the LED is in effect.
3. After indicating the firmware version, the EDID STATUS LED turns green if the selected EDID is valid, or turns red, if the selected EDID is invalid.
4. If a display device is connected to DVI OUTPUT 1, the DA2DVI-Pro reads the EDID from the attached monitor’s EDID memory.
If the read process is successful, the GREEN LED blinks a few times then the EDID Status LED shows whether the selected EDID is valid (green) or not (red).
If the read process is unsuccessful, the RED LED blinks a few times then the EDID Status LED shows whether the selected EDID is valid (green) or not (red).
Info If none of the LEDs light up upon power-up, the unit is most likely damaged and
further use is not advised. Please contact [email protected]
2.2. Learning an EDID
The factory preset EDIDs cannot be changed by the user. Only addresses from 51 to 99 are user programmable.
1. After connecting the sink device to DVI OUT 1, use a screwdriver to select the desired memory address. EDID are stored in multiple programmable non-volatile memories.
If the EDID status LED is illuminated RED, then the memory slot is empty and ready to be programmed. If GREEN, the memory was already used before, but still available for programming.
2. Push the LEARN button on the front side of the DA2DVI-Pro and hold it down for approximately 3 seconds.
Once the button is pushed the EDID status LED goes dark. If the storing was successful, the GREEN EDID status LED blinks five times and stays illuminated. If the store process was unsuccessful, the RED EDID status LED blinks five times and stays illuminated either red or green, depending on the status of the selected EDID.
Page 16
Page 16 / 43
2.3. Switching the EDID
1. Use a screwdriver to change the memory address on the front side of the DA2DVI-Pro.
After either one of the rotary switches has been rotated the unit waits approximately 2 seconds before the selected EDID becomes active. If the EDID status is unchanged the EDID STATUS LED does not blink.
2. The address 00 (zero zero) has a special function. If a monitor is connected to DVI OUTPUT 1, then its EDID is copied to the DVI INPUT. If no monitor is connected to the Monitor output then the EDID provided on the DVI INPUT connector is the EDID of the last connected monitor.
Info If an invalid EDID is selected, the DA2DVI-Pro does NOT transmit a HOT PLUG
signal to the source connected to the DVI INPUT.
Info After every EDID change, DA2DVI-Pro toggles the HOT PLUG signal for
approximatley 1 second. Some graphic cards or DVD players do not sense the HOT PLUG signal, and even if EDID has been changed, the set resolution is not affected. In this case the source device must be restarted, or powered OFF and ON again.
2.4. Factory preset EDID list
Lightware factory preloaded EDID are specially provided to force graphic cards to output only the exact pixel resolution and refresh rate.
Universal EDID (address 49) allows multiple resolutions including all common VESA defined resolutions. In addition, it also features audio support. The use of universal EDID is advised for fast and easy system setup.

3. Front panel control - DIP switch settings
Advanced users can make adjustments using an 8 circuit DIP switch located on the rear panel of the DA2DVI-Pro (see chapter 1.7.2).
SW 1: defines whether the DA2DVI-Pro is controlled by the rotary switches and the DIP switch or the Lightware Matrix Controller software via USB connection.
SW 2-3: if the incoming signal has too much jitter resulting from a low quality source, then a higher TMDS PLL filter frequency may be necessary. The default value of 4 MHz should provide the best results in most cases. CAUTION! Setting a higher frequency slightly decreases the quality of the output signal.
SW 4-5-6: if the clock and pixel data are not perfectly aligned in the internal pixel signal, then there’s a possibility to add some skew between them in both directions. There is no widely accepted value, because it depends on the resolution and pixel clock. A default setting of -2 should provide the best results in most cases.
SW 7: it is recommended to enable the Pixel PLL at all times. If the quality of the incoming signal is too low and the other settings could not improve the quality, then disabling the Pixel PLL may be necessary.
SW 8: this is a coarse way to adjust the deskew value. This setting shifts the phase of the clock signal by 180 degrees.

4.3. EDID menu
4.3.1. EDID Router operation
By clicking on the EDID menu, the EDID router window appears.
When the user enters the menu for the first time, the software starts to download the whole EDID content from the DA2DVI-Pro. It may take about 10-20 seconds.
After the list is downloaded, the current status of the EDID list is shown in two windows (list window areas). In the drop-down menus above the two windows you can select which part of the EDID memory you want to see.
The Emulated EDID List window contains the resolution, manufacturer and vendor name of the EDID emulated or reported to the source. The source column displays the memory location that the current EDID was routed from.
The Last attached Monitor's EDID List window contains the resolution, manufacturer and vendor name of the display device connected to DVI OUTPUT 1.
The Factory EDID List window shows the fifty factory preprogrammed EDID.
The User EDID List shows the memory locations which can be used by the user to save EDID.
List window areas
Change emulated EDID at the input – Drag and Drop
The two main types of the emulation are the static and the dynamic:
Static EDID emulation: when an EDID from memories 1…100 is selected and
emulated at the input(s)
Dynamic EDID emulation: when an attached monitor’s EDID is emulated at
input(s), simply copying the data from the monitor. This EDID changes immediately and automatically, if a new monitor is attached to the output.
Page 21
User’s Manual Rev. 1.3
Page 21 / 43
The process of emulating an EDID is the following:
1. Select the Emulated EDID List in one of the list window areas in the drop-
down menu.
2. Select the desired EDID from one of the list windows.
3. Drag and drop the EDID to the desired location in the Emulated EDID list.
Info: If the monitor’s EDID was selected to be emulated (DVI OUTPUT 1) the currently
emulated EDID will be changed on the input every time a new monitor is connected. If the monitor is disconnected from the output, the last EDID remains active, it will not be deleted from the input. This feature helps especially rental technicians or system integrators to keep the source continuously transmitting the signal, and adopt the system for new incoming display devices.
Info: Power ON/OFF cycle will not affect the emulated EDID or other settings.
Info: EDID switch procedure causes a status change and hence it is reported back to
the CONTROL SOFTWARE within 2-3 seconds.
Learn EDID from attached display device
The system is able to learn the EDID from the connected display device and store it in one of the user programmable memory locations.
1. Select User Memory in one of the list window areas in the drop-down menu.
2. Select the EDID to be saved from the other list window.
3. Drag and drop the selected EDID to the desired User Memory location.
Load EDID from file to memory
The DA2DVI-Pro is able to learn and store EDID from a file located on the computer. EDID are stored in *.dat files.
1. Select the User Memory list window from one of the drop-down menus, and
right click on the desired memory location. Then select “Load from file” from the pop-up menu.
2. Browse your hard drive to find the EDID file in the pop-up window. The
software checks whether the selected file is a valid EDID file.
3. Click Open in the browser window. After the process finished, ”EDID Upload
completed” message appears.
Save EDID from memory to file
The control software is able to download EDID from the DA2DVI-Pro and to save it as an EDID file.
1. Right click on the EDID to be saved.
2. Click on Save to file in the pop-up window.
3. The Matrix Controller Software downloads the desired EDID and a save
dialog appears. It may take a few seconds to download the EDID. If the save dialog is shown, type in the file name, and press Save button. After the process was completed, an ”EDID saved!” message confirms the command.
Page 22
Page 22 / 43
Synchronize EDID
By clicking on Synchronize EDID List button the Lightware Matrix Controller software rereads all EDID information from the connected DA2DVI-Pro. During normal operation it is not necessary to use this menu function because the DA2DVI-Pro always reports every status change automatically. No status change is reported, if you emulate the same EDID on the input or connect the same display device to DVI OUTPUT 1.
Info: There is always a small delay in responses. So if a new monitor is connected to
DVI OUTPUT 1, its new EDID is not shown immediately but in 2-3 seconds!
4.3.2. Advanced EDID Editor
The Lightware Advanced EDID Editor is integrated into the Lightware Matrix Controller software. By clicking on the green arrow, the editor area rolls down.
When the user enters the menu for the first time, an empty EDID is loaded into the editor’s memory.
All EDID in the DA2DVI-Pro’s memory can be edited in the following way:
1. Right click on the desired EDID to be loaded to the EDID Editor.
2. In the pop-up menu, click on Edit EDID. The editor area automatically rolls down, and the EDID is loaded into the editor area.
For further information, see the user’s manual of Advanced EDID Editor.
4.4. Terminal menu
This general-purpose serial terminal is intended mainly for test and debug purposes. After a successful connection to the DA2DVI-Pro this terminal can be opened and used via the USB connection. All commands can be used here that are discussed in section 1.1 and can be typed directly.

Serial Parameters
PLL Bandwidth Adjusts the TMDS PLL filter bandwith. SW 2 and 3 of the
DIP switch also adjust this value on the rear panel of the DA2DVI-Pro. If the incoming signal has too much jitter resulting from a low quality source, then a higher PLL fileter bandwidth may be necessary. The default value of 4 MHz should provide the best results in most cases. CAUTION! Setting a higher frequency slightly decreases the quality of the output signal
Output strength Adjusts the internal clock or data drive strength. The
default setting of High should always be applied.
Polarity SW 8 of the DIP switch adjusts this setting on the rear
panel of the DA2DVI-Pro. This is a coarse adjustment of the deskew value. This setting shifts the phase of the internal clock signal by 180 degrees.
Parallel Parameters
De-skewing SW 4, 5 and 6 of the DIP switch adjust this value on the
rear panel of the DA2DVI-Pro. If the clock and pixel data are not perfectly aligned in the internal parallel signal, then there’s a possibility to add some skew between them in both directions. There right value may depend on the resolution and pixel clock. A default setting of -2 should provide the best result in most cases.
PLL Filter SW 7 of the DIP switch enables this setting on the rear
panel of the DA2DVI-Pro. It is recommended to turn on the Pixel PLL at all times. If the quality of the incoming signal is too low and the other settings could not improve the quality, then disabling the Pixel PLL may be necessary. Different values adjust the pixel PLL filter frequency. Using value 4 is strongly recommended.
Sync Always use the ON setting.
Output Signal This setting is used to mute the output signal.

Ethernet and available COM ports of the computer.
Info: You must wait until every device boots up completely before pressing FIND button.
Step 3. Double click on the COM port that the DA2DVI-Pro is connected to. The
bootloader cannot identify the devices on the COM ports so if you are unsure about which virtual COM port the DA2DVI-Pro is connected to, run the Matrix Controller software and check.
Page 34
Page 34 / 43
Step 4. After establishing the connection, the bootloader identifies the controller
types, hardware versions, bootloader versions and the firmware versions of the selected device. Click on the Browse New Firmware area in the appropriate row. Now you can browse for the new firmware file to upload.
Step 5. To enable the upgrade, you need to check the checkbox next to the
DA2DVI-Pro’s name. Now click on the UPGRADE SELECTED FIRMWARES button and select YES in the pop-up window.
Page 35
User’s Manual Rev. 1.3
Page 35 / 43
Step 6. If the upgrade was completed without errors, the bootloader displays an
Upgrade Successful message. After clicking on OK button, you can close the connection by exiting the bootloader or select another device to upgrade.
Step 7. After the firmware upgrade, please switch the device off and on again.

6. Troubleshooting
6.1. USB connection problems
Check the cable and software settings
Check whether your USB cable is properly connected. In most cases there are more COM ports present in the operating system. Please verify the connection settings of your software. The DA2DVI-Pro’s virtual COM port communicates with
9600 Baud, 8 data bit, No parity, 1 stop bit.
6.2. There is no picture
Check the cables
Due to the high data rates, the cables must fit very well. DVI connectors have to be locked with screws, no tensions or breaches are allowed. If your source or display has more connectors then make sure that the proper interface is selected.
Check the incoming signal
Check the Source Connected LED on the front panel of the DA2DVI-Pro. This LED indicates the presence of the +5V signal coming from the DVI source. If it is not illuminated, then your DVI source is not working properly. Please refer to the user’s manual of your DVI source.
Check the Signal Present LED on the front panel of the DA2DVI-Pro. This LED indicates the presence of an active incoming DVI clock signal. If it is not illuminated, then no DVI clock signal is present at the input connector of the DA2DVI-Pro. Please check whether your source is configured to output a video signal.
Run the control software and check whether a video signal is present at the input or not. If there is a video signal, then the input port number I1 has an orange background. If I1 has a white background, then there is no video signal, please continue at chapter 6.3.
Check the outgoing signal
Check the Monitor Hotplug 1/2 LED on the front panel of the DA2DVI-Pro. This LED indicates the presence of the Hotplug signal coming from the attached display device. If it is not illuminated, then your display is not powered or not configured properly.
Right click on the output number in the crosspoint area (O1 or O2) to open the DVI output settings window in the control software. Try reloading factory default settings to the output. If it doesn’t help, then try adjusting the different settings. You will find help for this in section 1.1.
Check EDID related problems
Check the EDID Status LED on the front panel of the DA2DVI-Pro. This LED indicates whether a valid EDID is selected. If it is illuminated RED, then an invalid EDID or an empty memory address is selected. Please select a valid EDID.
If the EDID Status LED is illuminated GREEN, then maybe your display device is not capable of receiving the sent video format. Try emulating your display device’s EDID to the source. You will find help to this process in section 1.1. If you get a picture now, you have an EDID related issue, please read chapter 1.3 for more details.
Page 37
User’s Manual Rev. 1.3
Page 37 / 43
6.3. There is no input signal
Check the source
Check whether your source is powered on and configured properly. If the source is a computer, then verify that the DVI output is selected and active. Try restarting your computer; if you get a picture during the booting process, you have to review the graphics card’s driver settings in the operating system.
Check the EDID
Maybe the data rate is too high for that type of cable. Try switching another EDID to the inputs with lower resolution. If the source is a computer and you are an expert user, you can try modifying the refresh rate, so you would be able to get it to work at higher resolutions over a noisy connection.
