2.4. Understanding EDID
2.4.1. Basics
EDID stands for Extended Display Identification Data. Simply put, EDID is the
passport of display devices (monitors, TV sets, projectors). It contains information
about the display’s capabilities, such as supported resolutions, refresh rates (these
are called Detailed Timings), the type and manufacturer of the display device, etc.
After connecting a DVI source to a DVI display, the source reads out the EDID to
determine the resolution and refresh rate of the image to be transmitted.
Most DVI computer displays have 128-byte long EDID structure. However, Digital
Televisions and HDMI capable displays may have another 128 bytes, which is
called E-EDID and defined by CEA (Consumer Electronics Association). This
extension contains information about additional Detailed Timings, audio
capabilities, speaker allocation and HDMI capabilities. It is important to know, that
all HDMI capable devices must have CEA extension, but not all devices are HDMI
capable which have the extension.
2.4.2. Common problems related to EDID
Problem: „My system consists of the following: a PC, then a Lightware DVI-TP-
TX200DL, a WQXGA (2560x1600) LCD as local monitor, then a DVITP-RX100DL connected to a QXGA (2048x1536) projector. I would like
to see the same image on the monitor and the projector. What EDID
should I chose on the DVI-TP-TX200DL?” (see typical application in
section 2.9)
Solution: If you want to see the image on both displays, you need to select the
resolution of the smaller display (in this case QXGA), otherwise the
smaller display may not show the higher resolution image.
Page 9
DVI-TP-TX200DL/RX100DL
User’s Manual Rev. 1.0
Page 9 / 29
Problem: „I turned the rotary switches on the DVI-TP-TX200DL to have a different
resolution but nothing happens.”
Solution: Some graphics cards and video sources read out the EDID only after
power-up and later they don’t sense that EDID has been changed. You
need to restart your source to make it read out the EDID again.
Problem: „I have a DVI-TP-TX200DL and I’m using a Lightware factory preset
EDID. I would like to be able to choose from different resolutions, but
my source allows only one resolution.”
Solution: Most Lightware factory preset EDID allow only one resolution, forcing
the sources to output only that particular signal. You need to select the
Universal EDID (address 49). It supports all common VESA resolutions.
Additionally it also features audio support.
2.5. Advanced EDID Management (DVI-TP-TX200DL)
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.
DVI-TP-TX200DL provides Lightware’s Advanced EDID Management function that
helps system integration. It stores and emulates 99 EDID plus the EDID of the
display device which is connected to Monitor Output. Memory addresses from 01 to
50 are factory presets, while memories from 51 to 99 are user programmable. DVITP-TX200DL stores the EDID of the monitor or projector connected to Monitor
Output in a non-volatile memory.
The EDID emulated on the input can be copied from the DVI-TP-TX200DL's
memory (static EDID emulation) or from the attached monitor (dynamic emulation).
For example, the DVI-TP-TX200DL can be set up to emulate the device, which is
connected to MONITOR OUTPUT, 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 a source
is connected to the input and it is powered ON.
2.6. TMDS Reclocking (DVI-TP-RX100DL)
DVI-TP-RX100DL reclocks the signal on its output using Lightware’s sophisticated
TMDS 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 and event controllers. When transmitting the signal through long
cables without reclocking on the receiver side, sparkles, noise and jaggies can be
seen on the image.
Info TMDS stands for Transition Minimized Differential Signaling. It is the electrical and
encoding specification used by the DVI standard for the transmission of the video
signal.
Page 10
Page 10 / 29
The TMDS 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.
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.
Info TMDS Recklocking technology does not eliminate Inter-pair skew.
2.7. Dual link DVI signal
The dual link DVI interface can operate in either single link or dual link mode. The
chosen mode depends on the pixel clock frequency of the signal and it is selected
by the hardware automatically. For pixel clock frequencies lower than 165 MHz,
single link mode is selected. For higher pixel clock frequencies (up to 330 MHz),
dual link mode is selected. It is important to know that pixel clock frequency is not
the same as TMDS clock frequency when it comes to dual link DVI.
The pixel clock frequency in single link transmission is a 10th part of the data rate.
The maximum data rate of single link transmission is 1.65 Gbps per TMDS channel
and the maximum pixel clock frequency is 165 MHz. In this case the pixel clock
frequency equals the TMDS clock frequency.
The pixel clock frequency in dual link transmission (when in dual link mode) is a 5
th
part of the data rate. The maximum data rate of dual link transmission is still
1.65 Gbps per TMDS channel but the maximum pixel clock frequency is 330 MHz.
In this case the pixel clock frequency is two times the TMDS clock frequency.
Page 11
DVI-TP-TX200DL/RX100DL
User’s Manual Rev. 1.0
Page 11 / 29
The DVI standard maximizes the data rate of the TMDS channels in 1.65 Gbps.
Dual link DVI interface enables a higher resolution compared to single link
transmission by doubling the number of wire pairs to transmit the video signal. In
single link cables 3 wire pairs carry the color information (red, green and blue) and
one wire pair carries the clock signal (TMDS clock). In dual link cables, 6 wire pairs
carry the color information next to the TMDS clock signal. One color component is
carried by two wire pairs, where one wire pair carries the odd pixels and the other
wire pair carries the even pixels.
Video lines of the single link interface
Video lines of the dual link interface
Info The colors of the wire pairs in the picture represent the color information they carry
and not the color of the actual wires inside the cable.
2.8. Fiber Cable powering
As a special feature, both DVI-TP-TX200DL (MONITOR OUTPUT) and DVI-TPRX100DL (DVI OUTPUT) are able to supply 500 mA current to power fiber optical
transmitters like Lightware DVI-OPT-TX100 (Pin 14 on DVI OUT connector).
Standard DVI outputs or VGA cards supply only 55 mA current on +5V output, thus
unable to directly power a fiber optical transmitter.
Info DVI-TP-TX200DL and DVI-TP-RX100DL do not check if the connected sink
(monitor, projector or other equipment) supports Hotplug or EDID signals but
outputs the input signal immediately after it has been applied to the input.

Address selection Status LEDs DVI Input connector
Learn EDID button
EDID Address The rotary switches select one of 100 addresses. Addresses
1…50 are factory preset and 51…99 are user programmable.
Address 00 enables transparent mode. For more information,
see chapter 3.3. Use a flat head screwdriver that fits into the
actuator. Avoid the use of keys, coins, knives and other sharp
objects because they might cause permanent damage to the
rotary switches.
Learn EDID button Stores the EDID of the display device attached to MONITOR
OUTPUT in the selected memory address between 51…99. To
learn the EDID, select an appropriate address with the rotary
switches and press and hold the Learn button for two seconds.
EDID status LEDs Function 1: display the firmware version of the device. For more
information, see chapter 3.1.
Function 2: after applying a Hot Plug signal to MONITOR
OUTPUT, these LEDs indicate that the unit is reading the EDID
from the connected display device. If the green LED is blinking
then the EDID is valid, if the red LED is blinking, then the EDID
is invalid or missing.
Function 3: (main function) these LEDs indicate whether the
selected EDID is valid (green = valid, red = invalid or empty
memory selected).
Function 4: after pressing the LEARN button, these LEDs
indicate whether the learn process was successful (green
blinking = successful, red blinking = unsuccessful). For more
information, see chapter 3.2.
Monitor LED Indicates if a display device (or matrix switcher, repeater, etc.)
is connected to the MONITOR OUTPUT connector and sends a
valid Hot Plug Signal on Pin 16 through the DVI cable.
SRC +5V LED Indicates if a DVI source is connected to the DVI-TP-TX200DL,
it is powered on and sends +5V signal to Pin 14 of the input DVI
connector.
DVI Input Connect one dual link DVI-D or DVI-I cable (only digital pins are
connected internally) between the DVI source and DVI-TPTX200DL.

clock frequency of 165 MHz, a single link cable can be used.
For more information, see chapter 2.7.
The output connector is able to supply 500 mA current on
pin 14 to power fiber optical DVI extenders like DVI-OPTTX100.
If a long DVI cable is connected then equalization and
reclocking may be necessary at the receiver end of the cable.
CAT A-B Outputs Connect two CAT5, CAT5e, CAT6a or CAT7 (recommended)
cables between DVI-TP-TX200DL and the receiver (DVI-TPRX100DL or Lightware Hybrid Matrix equipped with dual link
twisted pair input cards).
If a lower resolution image is transmitted, with a maximum pixel
clock frequency of 165 MHz, then only one CATx cable needs
to be connected to CAT-A output.
Accidental connection of the CAT-A output of the DVI-TP-
TX200DL to the CAT-B input of a Lightware dual link twisted
pair receiver (and vice versa) does not result in damage to the
unit but it may result in faulty behavior. Please turn off the
devices, disconnect the cables and connect the cables to the
appropriate connectors.
The DVI-TP-TX200DL does not have networking capabilities.
Do not connect the RJ45 output of the DVI-TP-TX200DL to a

EQ mode status LEDs Two LEDs indicate whether the DVI-TP-RX100DL is in auto or
manual equalization mode. Automatic mode usually gives a
good result, but at long distances, manual equalization may be
necessary. For more information, see chapter 4.2.
Signal Present LED Indicates if a valid DVI clock signal is present on CAT-A input
RJ45 connector. The CAT-A cable carries the clock signal,
therefore the unit can operate if only the CAT-A cable is
connected, but cannot operate if only the CAT-B cable is
connected. The presence of any video signal on the CAT-B
input is not indicated.
Monitor Hotplug LED Indicates if a display device (or matrix switcher, repeater, etc.)
is connected to the DVI OUTPUT connector and sends a valid
Hot Plug Signal on Pin 16 through the DVI cable.
EQ Mode button Toggles between automatic and manual EQ mode. The EQ
mode status LEDs indicate which mode is currently active.
EQ level adjust The 25-turn potenciometer can be used to precisely set the
right amount of equalization in manual EQ mode. The
potenciometer does not stop at the end positions, but rotates
indefinitely. After reaching the end position, a clicking sound
can be heard at every full turn of the knob.

3. Operation of DVI-TP-TX200DL
3.1. 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 output of the +5V Power Adaptor
to the DVI-TP-TX200DL (further on TX200DL) The unit is immediately
powered ON.
2. After being powered on, the TX200DL displays its firmware version using the
EDID Status LEDs.
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 red EDID status LED lights up for 23 seconds, then turns green if the selected EDID is valid, or remains red, if
the selected EDID is invalid (or the selected memory slot is empty).
After the TX200DL is initialized, the attached DVI source and monitor can be
powered on.
4. If a display device is connected to MONITOR OUT, the TX200DL reads the
EDID from the attached monitor’s EDID memory.
If the read process is successful, the GREEN LED blinks several times then
the EDID Status LEDs show whether the selected EDID is valid (green) or
not (red) on the DVI INPUT connector.
If the read process is unsuccessful, the RED LED blinks several times then
the EDID Status LEDs show whether the selected EDID is valid (green) or
not (red) on the DVI INPUT connector.
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]
3.2. Learning the 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 MONITOR OUT, use a screwdriver to
select an empty memory address. EDID are stored in a multiple
programmable non-volatile memory.
If the red EDID status LED is illuminated, then the memory slot is empty and
ready to be programmed. If the green EDID status LED is illuminated, the
memory was already used before, but still available for programming.
2. Push the LEARN button on the front side of the TX200DL and hold it down
for approximately 3 seconds.
Once the button is pushed the EDID status LEDs go dark. If the EDID storing
was successful, the green EDID status LED blinks five times and stays
illuminated. Now the stored EDID is automatically emulated.
If the storing was unsuccessful, the red EDID status LED blinks five times
and either the red or green EDID status LED becomes illuminated,
depending on the previous status of the selected EDID address.

3.3. Switching the EDID
1. Use a screwdriver to change the memory address on the front side of the
TX200DL.
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 LEDs do not blink, but stay
continuously lit.
2. The address 00 (zero zero) has a special function. If a monitor is connected
to MONITOR OUT, then its EDID is copied to the DVI INPUT connector. If
no monitor is connected to the output then the EDID transmitted to the DVI
INPUT connector is the EDID of the last connected monitor.
Info If an invalid EDID is selected, the TX200DL does NOT give a HOT PLUG signal to
the source connected to DVI INPUT.
Info After every EDID change, TX200DL toggles the HOT PLUG signal for approx. 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.
3.4. Factory preset EDID list
Lightware factory pre-loaded EDIDs 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 recommended for fast and easy system setup.

4. Operation of DVI-TP-RX100DL
4.1. 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 output of the +5V Power Adaptor
to the DVI-TP-RX100DL (further on RX100DL). The unit is immediately
powered ON.
2. After being powered on, the RX100DL displays its firmware version using the
EQ mode status LEDs.
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, either the red or green EQ mode status
LED stays continuously lit, depending on the last selected mode.
After the RX100DL is initialized, the attached monitor can be powered on.
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]
4.2. Adjusting the input equalization
The amplitude of high frequency signals decreases after they pass through long
distances in copper cables. To counter-act this phenomenon, RX100DL amplifies
the signal while maximizing the amplitude at a certain level, which is defined by the
DVI 1.0 standard. This process is called equalization.
The RX100DL offers two equalization modes: automatic and manual. Automatic
mode usually provides perfect transmission but at longer distances and higher
resolutions, manual equalization may be necessary.
1. Select the equalization mode by pressing and releasing the EQ mode
selection button once. The two EQ mode status LEDs show which mode is
currently active.
2. Use a 2-3 mm flat head screwdriver to manually adjust the equalization level.
Turning the knob clockwise increases the EQ level, turning it
counterclockwise decreases the EQ level. The knob of the potenciometer
does not stop at the end positions, but rotates indefinitely. After reaching the
end position, a clicking sound can be heard at every full turn of the knob.
IMPORTANT! When installing the RX100DL in a system, always check which
equalization mode is selected, because a previously set manual equalization level
may not be suitable for a different system. It is always advised to use the automatic
mode and only adjust the equalization manually if the auto mode does not give a
good result.

4.3. Maximum twisted pair distances
The following table shows the maximum twisted pair distances. The actual
achievable distances may differ, depending on the topology of the whole system.
Unshielded Twisted Pair (UTP) cables are susceptible to EMI coming from
surrounding devices (cables, mobile phones, motors, etc.). Noisy environments
substantially decrease the usable length of unshielded cables. Hence the use of
shielded Category 6 cables or Category 7 cables is always recommended.
Category 7 cables are screened and foiled by standard.

5. Troubleshooting
5.1. 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 if the CATx cables are connected properly between the transmitter and
receiver (CAT-A output to CAT-A input, CAT-B output to CAT-B input).
Accidental connection of the CAT-A output of the DVI-TP-TX200DL to the CAT-B
input of DVI-TP-RX100DL (and vice versa) does not result in damage to the unit
but it may result in faulty behavior. Please turn off the devices, disconnect the
cables and connect the cables to the appropriate connectors.
The length of the two CATx cables must match very closely. If the cable lengths
don’t match, then the picture may not display or may become noisy.
Check the source equipment
Check the Source Connected LED on the front side of the DVI-TP-TX200DL. 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.
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 driver settings.
Page 22
Page 22 / 29
Check the incoming signal
Check the Signal Present LED on the front side of the DVI-TP-RX100DL. 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 CAT-A input connector.
Make sure that the proper equalization mode is selected and if manual mode is
active, the right amount of equalization is set.
Check if there’s an outgoing signal on the Monitor Output connector of the DVI-TPTX200DL (also check the Monitor LED on the front panel). The input signal is
always routed to the DVI and RJ45 output connectors. If there is a signal on the
Monitor Output connector, then the problem is not EDID related. Check if the CATx
cables are connected properly.
Check the display status
Check the Monitor Hotplug LED on the front side of the DVI-TP-RX100DL. 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.
Check EDID related problems
Check the EDID Status LEDs on the front side of the DVI-TP-TX200DL. These
LEDs indicate whether a valid EDID is selected. If the red LED is illuminated, then
an invalid EDID or an empty memory address is selected. Please select a valid
EDID.
If the green EDID Status LED is illuminated, 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 3.3. If you get a
picture now, you have an EDID related issue, please read section 2.4 for more
details.
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.
