Thank you for choosing Lightware’s DVI-OPT-110 series devices. In the first chapter we would like to introduce the device by highlighting the most important features in the sections listed below:
DVI-OPT-TX110 and DVI-OPT-RX110 pair is a DVI to fiber transmitter / receiver set for up to 2500 m distance transmission. Using Single Fiber Technology, the DVI-D signal is transmitted over only one multimode 50/125 fiber core. Sources and display devices are galvanically isolated against ground loops and hum effects, and no delay occurs in the signal, the video is transported without any frame latency.
About the Serial Number
Lightware devices contain a label indicating the unique serial number of the product. The structure is the following:
From 1st of October 2024, serial number format of Lightware devices is the following: the first two digits are of the year of manufacture, while the remaining digits make up the running sequence number.

2.2.1. Using the LEARN Button (Transmitter)
▪When the button is pressed, the EDID state LED turns off to indicate the button press.
▪If the button is released sooner than two seconds, the press will be ignored.
▪If the button is pressed for more than two seconds, the EDID learn mode gets activated for a period of 10 seconds.
▪If the button is pressed for more than 10 seconds and the unit is not connected to a display device, the factory default EDID will be restored.
2.2.2. Learning an EDID (Transmitter)
Step 1.Plug in the power adaptor to an electrical outlet, or plug in the enclosed USB power cable to a USB connector, and then connect the DC cable to the transmitter.
Step 2.The power and the EDID state LEDs light up.
Step 3.Press and hold down the LEARN button for two seconds. The EDID state LED goes dark, and then lights up orange to indicate that Learn mode is activated.
Step 4.Connect the transmitter to a display device; the learn mode is active for 10 seconds.
Step 5.The transmitter reads the EDID from the display device. Do not disconnect the device while it lights orange (approximately 10 seconds).
Step 6.Check if the learning succeeded:
=If the learning process was successful, the EDID state LED blinks green slowly for eight seconds. The stored EDID is changed.
=If the learning process failed, the EDID state LED blinks red slowly for eight seconds. The previously stored EDID remains in the memory.
=The EDID state LED changes to continuous green or red depending on the validity of the stored EDID.
Step 7.Disconnect the transmitter (if still connected) and the power supply. The stored EDID remains in the memory until it is overwritten. The unit is ready to be used for DVI signal extension.
2.2.3. Restoring the Factory Default EDID (Transmitter)
Step 1.Power up the transmitter by
=a) using one of the external power supplies
=b) connecting it to a DVI source.
Step 2.Press and keep pressing the LEARN button. The EDID state LED goes dark for two seconds, and then turns orange to indicate that learn mode is activated. (Do not connect the unit to a display device.)
Step 3.Keep the button pressed until the LED starts to blink orange (after approximately 10 seconds). Five blinks indicate the EDID restoration process.
Step 4.After the restoration process is finished, the LED blinks green slowly for eight seconds. The stored EDID is changed back to factory default (1920x1200@59.55Hz).
Step 5.The unit is ready to be used for DVI signal extension.

This chapter is about the installation of the device and connecting to other appliances:
Locking DC connector
The extenders are built with a locking 5V DC connector. Do not forget to turn the plug clockwise before disconnecting the power adaptor.
WARNING!Always use the supplied 5V power adaptor. Warranty void if damage occurs due to use of a different power source.
3.1.2. SC Fiber Optical Connector
HDMI-3D-OPT-DD series transmitter and receiver provide multimode SC fiber optical input and output connectors.
Maximum fiber cable distances can be found in the Maximum Fiber Cable Extensions section.
WARNING!Please do not look directly into the SC fiber optical connector if the cable is connected to the transmitter only and the laser is active.
29 pole DVI-I connectors only have digital pins internally connected. This way, users can plug in any DVI connector, but keep in mind that analog signals (such as VGA or RGBHV) are NOT available.
A 5V DC power adaptor supplied with the extender that is suitable to power the unit.
A special USB-A-DC cable with a 1.35/3.5 mm plug on the other end that is supplied with the extender and can be used to supply the unit with power.
3.2.3. DVI Connector (via +5V pin)
In case the unit is connected to a device (e.g. a matrix) that contains DVI outputs that are able to supply 500 mA current on DDC +5V output (pin 14 on output connectors) which is sufficient to supply power to hybrid fiber optical DVI cables. Standard DVI outputs usually supply only 55 mA current on +5V output, thus are unable to directly power a fiber optical cable.

Connect a multimode SC fiber cable to the SC MM IN connector on the DVI-OPT-RX110 unit. |
|
|
Connect the receiver to the DVI sink (e.g. monitor). |
|
|
Power on the DVI sink (monitor). |
|
|
Connect the other end of the multimode SC fiber cable to the SC MM OUT connector on the DVI-OPT-TX110 unit. |
|
|
Connect the transmitter to a DVI source (e.g. computer). |
|
|
Power on the DVI source (computer). It reads the EDID from the transmitter and outputs the video signal according to the set resolution. |
|
|
Check the LEDs on the transmitter: |
If both the Power LED and the EDID status LEDs are green, the transmitter is ready to use. |
|
|
If the Power LED does not light up, the DVI source does not send enough power through the DVI connector, so the external power adaptor or the special USB cable needs to be connected to the transmitter. |
||
|
If the EDID state LED lights red, an EDID needs to be learned. |
||

Usually, if the system seems not to transport the signal as expected, the best strategy for troubleshooting is to check signal integrity through the whole signal chain starting from source side and moving forward to receiver end:
At first, check front panel LEDs and take the necessary steps according to their states. For more information about front and rear panel LEDs of the devices, refer to Status LEDs sections.

4.2. How to Speed Up the Troubleshooting Process
Lightware’s technical support team is always working hard to provide the fastest support possible. Our team’s response time is one of the best in the industry, and in the toughest of cases we can directly consult with the hardware or software engineer who designed the product to get the information from the most reliable source.
However, the troubleshooting process can be even faster… with your help.
There are certain pieces of information that push us in the right direction to find the root cause of the problem. If we receive most of this information in the first e-mail, or it is gathered at the time when you call us, then there is a pretty high chance that we will be able to respond with the final solution right away. This information is the following:
▪Schematic (a pdf version is preferred, but a hand drawing is sufficient).
▪Serial number(s) of the device(s) (it is either printed somewhere on the box or you can query it in the Device Controller software or on the built-in website).
▪Firmware versions of the devices (please note that there may be multiple CPUs or controllers in the device and we need to know all of their firmware versions, a screenshot is the best option).
▪Cable lengths and types (in our experience, it’s usually the cable).
▪Patch panels, gender changers or anything else in the signal path that can affect the transmission.
▪Signal type (resolution, refresh rate, color space, deep color).
▪Emulated EDID(s) (please save them as a file and send it to us).
▪Actions to take in order to re-create the problem (if we cannot reproduce the problem, it is hard for us to find the cause).
▪Photo or video about the problem (‘image noise’ can mean many different things, it’s better if we see it too).
▪Error logs from the Device Controller software.
▪In the case of Event Manager issue, the event file and/or backup file from the Device Controller software.
▪The more of the information above you can give us, the better. Please send this information to the Lightware Support Team (support@lightware.com) to speed up the troubleshooting process.
