2.2. Transmitter features (DVI-TP-TX200 and TX300)
Advanced EDID Management – The user can emulate any EDID on the DVI-TP-
TX200/TX300’s input, read out and store any monitor's EDID
(attached to Monitor Output) in 49 internal memory locations.
Green and red EDID status LEDs show whether a valid address
is selected.
Supports all HDTV resolutions – 720p, 1080i and 1080p etc without HDCP
enoding. Unencrypted signals with up to 165 MHz pixel clock
frequency - regardless of the resolution - are passed through.
Source and Monitor Connected LEDs – Two LEDs indicate when a DVI source
and display device is connected to the DVI-TP-TX200/TX300:
the source is sending +5V signal and the display is sending Hot
Plug signal.
Local Monitor Output – The user can attach a local monitor to observe the video
signal sent through the CATx cables. The resolution and clock
frequency are the same on DVI and RJ45 connector(s), no
internal scaling or conversion is applied to the signal.
Dual CATx outputs (TX300 only) – A built-in distribution amplifier provides the
signal for two identical CATx outputs.
Front panel control – EDID Address selection with two decimal rotary switches
and Learn EDID button are available for Advanced EDID
Management.
Fiber cable support – Self powered DVI fiber cables using +5V from DVI sources
(VGA cards, etc.) usually consume more than 55 mA, which
load is the maximum allowed by DVI 1.0 standard. DVI-TPTX200/TX300 supports +5V/500 mA constant current output on
MONITOR OUTPUT to power fiber optical transmitters.

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-
TX200, a WUXGA (1920x1200) LCD as local monitor, then a DVI-TPRX100 connected to a SXGA (1280x1024) projector. I would like to see
the same image on the monitor and the projector. What EDID should I
chose on the DVI-TP-TX200?” (see typical application in section 2.8)
Solution: If you want to see the image on both displays, you need to select the
resolution of the smaller display (in this case SXGA), otherwise the
smaller display may not show the higher resolution image.
Page 9
DVI-TP-TX200/TX300/RX100
User’s Manual Rev. 1.0
Page 9 / 29
Problem: „I turned the rotary switches on the DVI-TP-TX200/TX300 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-TX200/TX300 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 EDIDs 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-TX200/TX300)
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-TX200/TX300 provides Lightware’s Advanced EDID Management function
that helps system integration. It stores and emulates 99 EDIDs 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. DVI-TP-TX200/TX300 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-TX200/TX300's
memory (static EDID emulation) or from the attached monitor (dynamic EDID
emulation). For example, the DVI-TP-TX200/TX300 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-RX100)
DVI-TP-RX100 reclocks the signal on its output using Lightware’s sophisticated
TMDS Reclocking technology. Signal reclocking is an essentially 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 to transmit 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 more than on bit of Inter-pair
skew.
2.7. Fiber Cable powering
As a special feature, DVI-TP-TX200/TX300 (MONITOR OUTPUT) and DVI-TPRX100 (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-TX200/TX300 and DVI-TP-RX100 do not check if the connected sink
(monitor, projector or other equipment) supports Hotplug or EDID signals but
output the input signal immediately after it has been applied to the input.

3. Operation of DVI-TP-TX200/TX300
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-TX200/TX300 (further on TX200/TX300) The unit is
immediately powered ON.
2. After being powered on, the TX200/TX300 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 is empty).
After the TX200/TX300 is initialized, the attached DVI source and monitor
can be powered on.
4. If a display device is connected to MONITOR OUT, the TX200/TX300 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. EDIDs 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 TX200/TX300 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.

User’s Manual Rev. 1.0
Page 19 / 29
3.3. Switching the EDID
1. Use a screwdriver to change the memory address on the front side of the
TX200/TX300.
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 TX200/TX300 does NOT give a HOT PLUG
signal to the source connected to DVI INPUT.
Info After every EDID change, TX200/TX300 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-RX100
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-RX100 (further on RX100). The unit is immediately powered
ON.
2. After being powered on, the RX100 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 RX100 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, RX100 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 RX100 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 RX100 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.
Check the source equipment
Check the Source Connected LED on the front side of the DVI-TP-TX200/TX300.
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.
Check the incoming signal
Check the Signal Present LED on the front side of the DVI-TP-RX100. 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 VIDEO 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-TPTX200/TX300 (also check the Monitor LED on the front panel). The input signal is
always routed to the DVI and RJ45 output connector(s). If there is a signal on the
Page 22
Page 22 / 29
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-RX100. 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-TX200/TX300. 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 chapter 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.
