1. Introduction

Thank you for choosing Lightware’s DisplayPort Fiber Optical extender devices. In the first chapter we would like to introduce the device, highlighting the most important features in the sections listed below:

1.1. Description

DisplayPort is one of the newest video interface standards. Using DisplayPort, high resolution video and excellent quality audio can be transmitted. The interface’s 10.8 Gbps bandwidth is capable of transmitting 2560x1600@60Hz pixel resolution video with full support of content protection (HDCP). UHD and 4Kx2K resolution can be achieved up to 30Hz frame rate.

Intelligent HID Emulation is provided for two devices with full transparency. The special HID devices – including keyboard and mouse – are emulated by the extender and transparently transferred to the computer with the result that no extra drivers are required for the proper functionality, it’s as easy as Plug & Play. DP-OPT-TX150 has 2 extra local USB ports with a built-in HUB and can be connected to the PC/Mac with a single USB cable.

When connecting a DVI or HDMI display through an adaptor cable, Dual-mode DisplayPort graphic cards reconfigure their outputs to DVI or HDMI accordingly. Lightware DisplayPort extenders support Dual-mode port extension and adaptor cables.

Lightware’s DisplayPort extenders can be used with Thunderbolt sources and devices. The extender pair and the DisplayPort monitor have to be placed at the end of the Thunderbolt chain. Apple Thunderbolt Display is not supported.

Single Fiber Technology makes these units fully DisplayPort 1.1a and HDCP 1.1 compliant without the need of a second fiber cable or copper connections. To simplify cabling, the bidirectional communication - necessary for DisplayPort Link Training, HDCP handshaking and USB transfer - is performed on the same fiber core that transmits the video signal. Both receiver and transmitter are remotely configurable from either side through the mini USB connector.

1.2. Model Denomination

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.

3.3. Security slot

A Kensington-compatible security slot can be found on the side of the units for theft protection. (Security cable is not supplied with the extenders.)

3.4. Connecting Steps

	Connect the desired source to the DP input port of the transmitter.
	Connect the supplied USB cable between the transmitter and a computer to extend USB HID devices, to connect local USB devices, and/or to control the extenders by LDC.
	Connect the desired local USB devices to the Transmitter and USB HID devices to the Receiver for USB KVM extension.
	Connect a DP sink device to the Receiver by a DP cable or an HDMI sink device by an HDMI cable and a DP/HDMI adaptor cable.
	Connect a multimode fiber optical cable between the transmitter and the receiver.
	Connect the power adaptor to the DC input on the receiver first, then to the AC power socket, or use Lightware's rack-mountable Power Supply Units.

3.5. Powering On

ATTENTION!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, which can damage sensitive electronic circuits.

After the system is complete, connect the DC power cable to the extender unit and then to the power outlet. The unit is immediately powered ON.

After the extender units are initialized, the attached DP source and monitor can be powered on.

ATTENTION!If the power LED does not light up upon power-up, the unit is most likely damaged and further use is not advised. Please contact support@lightware.com.

INFO:The laser becomes enabled any time the transmitter is powered on. This is done to avoid accidental laser loss problems.

3.5.1. Setting up USB Devices

DP-OPT-RX150 handles USB HID devices (Human Interface Device), which are input devices like the mouse, keyboard, presenter, pointing device, etc. Even though USB HUBs are supported (like those keyboards, monitors that have built-in USB HUB), only two devices are available for extension at the same time.

When the transmitter is connected to the computer by the USB cable, it can be used as a local USB 2.0 HUB. To build the USB connection, do the following steps:

Step 1.Connect the supplied USB cable to the transmitter’s mini USB connector.

Step 2.Connect the other end of the USB cable into an empty USB slot on the computer.

Step 3.Connect the HID device(s) to the receiver.

INFO:If the previously used USB devices are connected through the extenders to the computer, they may be handled as new hardware by the operating system the first time.

3.6. USB Modes

Two channels are used for the USB communication between the extenders. Channel A1 is always transparent and one USB HID device is always operable. The other channel’s state can be set, which determines the current USB mode.

Transparent USB Mode

Both channels are available for USB HID devices connected to the receiver. The default setting is the transparent USB mode, which means both USB HID devices connected to the receiver are transparently transmitted to the source computer.

USB channels in Transparent mode

Configuration USB Mode

Configuration USB mode is an option where the USB settings of the extenders can be configured by using the Lightware Device Controller. One channel (A1) is available for a USB HID device, the other channel (A2) is reserved for communication.

USB channels in Configuration mode

INFO:The USB mode has an effect only on the state of the transmitter. Receiver is always in configuration mode. Setting the USB mode on the receiver affects only the transmitter.

3.6.1. Changing the USB Mode

The USB mode can be changed in the transmitter or in the receiver, but in the latter case make sure that the extenders are linked by the fiber cables.

ATTENTION!If the USB mode is changed in the receiver when the extenders are not connected by fiber cable, the setting is stored in the receiver and the USB mode will be changed after reconnecting.

Step 1.Power ON the extender(s) and locate the hidden function button on the bottom side.

Step 2.Press and keep pressing the button with a thin tool (e.g. paper clip) for about two seconds. Release the button before not more than five seconds.

Step 3.The current USB mode is visible on the front panel.

ATTENTION!When the configuration mode is active, only one USB HID device can be used: the one that was connected to the receiver first.

INFO:The default setting (transparent mode) is restored when the device is powered on.

3.7. HDCP Setting

When a non-HDCP compatible sink is connected to the receiver, the source can be forced to output non-encrypted signal if the content is not protected. For more information about the HDCP management, see the HDCP Management section.

HDCP is enabled as a default setting, but can be changed as follows:

Step 1.Locate the hidden function button on the bottom side of the extender (either on TX150 or RX150).

Step 2.Press and keep pressing the hidden function button with a thin tool (e.g. paper clip) for at least 10 seconds (pressing the button for a shorter period changes the USB mode instead). If the extenders are in HDMI mode, the ‘HDCP enable’ LED status is changed before releasing the button.

ATTENTION!The HDCP setting can be changed in DP mode, but in this case the ‘HDCP enable’ LED will not show the change. The setting will be effective only after switching to HDMI mode. In DP mode HDCP is always enabled.

INFO:The HDCP setting is available in both extenders.

3.8. DP Mode and HDMI Mode

The extenders work in two modes according to the connected display device:

DisplayPort Mode (DP-DP cable)

When the DP output port of the transmitter is connected to the DP input port of the display device, the extenders are in DP mode. In this case the source sends DP signal.

Display is Connected by a DVI/HDMI Passive Adaptor

When the DP output port of the transmitter is connected to the DVI/HDMI port of the display device through a passive adaptor, the extenders and the source are in HDMI mode. In this case the source sends DVI/HDMI signal. See more information about the Dual mode in the HDCP Setting section.

4. Software Control - Lightware Device Contoller

The extenders can be controlled by a computer through the USB port using Lightware Device Controller (LDC). The software can be installed on a Windows PC or macOS. The application can be downloaded from www.lightware.com. The Windows and the macOS versions have the same look and functionality.

4.3.1. Video and Link Panel

Basic information is displayed about the extenders and the video signal. If the extenders are linked by fiber cable, they can read information about each other and the display.

INFO:Source can be forced to send unencrypted signal (if the content allows) by unchecking the HDCP enable setting.

INFO:HDCP enable setting can be changed in DP and HDMI mode as well, but has an effect only when a DVI/HDMI adaptor is connected. When HDCP is changed in DP mode, the setting is stored and will be applied when an adaptor is connected.

4.3.2. Transmitter Panel

The Control menu

Two channels are used for the USB communication, which can be set as described in the USB Modes section. Channel 1 is always transparent, Channel 2 can be set to transparent or configuration mode.

Parameter	State and Description
USB host (computer)	Connected
USB Channel 1 mode	Transparent (always)
USB Channel 1 state	Active Not connected (it depends on the HID devices)
USB Channel 2 mode	Configuration Transparent
USB Channel 2 status	Active

ATTENTION!USB Channel 2 mode can be changed through a drop-down menu. When switched to transparent mode, the extender is disconnected from the LDC immediately.

4.3.3. Receiver Panel

The panel consists of the lists that are showing connected and blocked USB devices.

Connected USB Devices

The listed devices are connected to the receiver’s USB ports.

Parameters

Parameter	State and Description
Manufacturer, Product, Type	As coded in the USB device.
CH (Channel)	Channel A1 and A2 are used for USB communication. A1 is always transparent, A2 can be switched. The USB device on Channel A1 is the one that was connected to the receiver the earliest.
Status	Active: the device is ready to use in transparent mode. Supported: the device is supported, but not active (no channel is available for extension). Unsupported: the device is not USB HID (e.g. pen drive).
VID, PID	Vendor ID and Product ID as coded in the USB device.
Address	See the following section.

The Address of the Device

Address of the device plugged in = 1 and the device plugged in = 2. Since a USB HUB can be connected to the receiver, the addresses are determined as follows:

▪Address of the USB HUB: 100 (not visible)

▪Address of the USB device connected to the first port of the USB HUB: 104

The example above shows a mouse that is connected to the USB port (Ch A1, Addr 2). The other device is a keyboard, which is connected via an USB HUB – that is why its address is not 1 but 101. Since the extenders are in configuration mode, only one device can be used: the one on channel A1 (the mouse).

Even though USB HUBs are supported by the receiver, only two devices are active at the same time in transparent mode: the devices that are closest to the root address. If an active device is disconnected, the next valid device (that is the closest to the root) will be active.

INFO:Channel A1 and A2 are assigned to the devices automatically when a new device is connected.

Port Numbers

The port numbers of the USB HUB determines the priority of the devices. When more devices are connected to an USB HUB, the USB port number determines the priority of the connected devices: the lower the number, the higher the priority. This priority has an effect when the channels are assigned to the devices.

Blocked USB Devices

The USB blocking feature allows you to activate the desired devices when more than two USB HID devices are connected to the receiver (two channels are available for USB extension). A typical example is shown in the Example 3: Connecting three USB HID devices and a HUB section.

Blocking a Device

Step 1.Click on the Block manually button, or select a device from the Connected USB devices list and click on Block selected button.

Step 2.Check the fields in the appearing window (Device name, Vendor ID, Product ID) and click on the Save button. The ID is the number of the blocked device in the list.

Step 3.Click on the Apply button in the bottom of the window to save changes. The desired device is added to the Blocked USB devices list and next time when you connect it to the receiver, its status will be displayed as Blocked.

Removing blocked devices

Step 1.Select the device from the Blocked USB devices list.

Step 2.Click on the Remove button.

Step 3.Click on the Apply button on the bottom of the screen to save changes.

INFO:The Remove all button will empty the list of blocked devices.

4.4. Real-life examples (USB devices and modes)

The background of the USB modes, connected USB devices, displayed information can be understood easier by presenting examples.

Example 1: Connecting Two USB HID Devices

Shown in the LDC:

In a simple case a keyboard and a mouse are connected to the receiver.

In Transparent mode both devices are operable.

In Configuration mode only one of them is available (as seen on the screenshot), the keyboard on channel A1. The second row (the mouse) is blinking, showing that the device is not available.

Example 2: Connecting Two USB HID Devices via an USB HUB

Shown in LDC:

This case is similar to the first, but now the mouse and the keyboard are connected to a local USB HUB. The HUB (with 4 available USB ports) is built into the monitor and connected to the receiver (the address of the HUB is 200). The keyboard is connected to the 2nd port (Addr. 202) and the mouse is connected to the 4th port of the HUB (Addr. 204).

In Transparent mode both devices are operable.

In Configuration mode only one USB HID device is available (as seen on the screenshot), the keyboard on channel A1. The second row (the mouse) is blinking, showing that the device is out of operation currently due to the USB mode.

Example 3: Connecting three USB HID devices and a HUB

Shown in LDC:

On the third example three USB devices can be seen. A mouse and a keyboard are connected to the USB HUB that is connected to one of the receiver’s USB ports. A presenter device is connected to the other USB port (the presenter is listed as “Keyboard”).

In Transparent mode two devices are operable: the presenter (on channel A1) and the keyboard (on channel A2). The presenter was connected to the receiver the earliest, that is why channel A1 is assigned to the presenter. The address number of the keyboard is lower than the mouse, that is why channel A2 is assigned to the keyboard. If you want to use the mouse, you have to block the presenter or the keyboard (the other option is to disconnect one of them).

In Configuration mode only one device is operable: the presenter on channel A1. The second row (the keyboard) is blinking, showing the device is not available due to the USB mode.

INFO:Channel A1 and A2 are assigned to the devices automatically when a new device is connected; they cannot be changed manually.

INFO:The port numbers of the USB HUB determine the priority of the devices. When more devices are connected to a USB HUB, the USB port number determines the priority of the connected devices: the lower the number, the higher the priority. This priority has an effect when the channels are assigned to the devices.

Example 4: Using an Apple LED cinema display

Shown in LDC:

The last example shows a special layout, where an Apple LED cinema display (with built-in USB HUB), a mouse, a keyboard and another simple USB HUB are installed. The layout could cause headache, since the display contains three components which report themselves as HID devices. The result is that the keyboard’s address is lower than the components in the display device and the keyboard will be operable neither in configuration-, nor in transparent mode.

The solution in this case is to block the unnecessary devices, shown in the 2nd and 4th rows. (The device in the 3rd row is not supported, it is not necessary to block.) Block the two devices:

This way in Transparent mode the mouse and the keyboard will be operable.

In Configuration mode only the mouse is available, that is why the last row is blinking.

4.5. Terminal Menu

The general purpose of this serial terminal is intended mainly for testing and debugging purposes. Nevertheless, when the window is open, the automatically executed commands can be followed on the screen.

Generating a Custom Report File

INFO:This function is only for special troubleshooting cases.

Device Controller is able to send a custom command file to the extender. The command file can be generated by Lightware support. This is needed when some special commands need to be used for configuring or troubleshooting.

5. Firmware Update

The extenders can be updated using the Lightware Device Updater (LDU) software via the USB port. The application and the User manual can be downloaded from www.lightware.com. In order to get the firmware pack with the necessary components (*.lfp file) for your specific product, please contact support@lightware.com.

ATTENTION!While the firmware is being updated, the normal operation mode is suspended, as the receiver is switched to bootload mode. Signal processing is not performed. Do not interrupt the firmware update. If any problem occurs, reboot the receiver and restart the process.

5.1. About the Firmware Package (LFP File)

The firmware files are packed in an LFP package. You need only this file to do the update on your device.

▪The package contains all the necessary components, binary, and other files; You do not have to get further files.

▪There is a descriptor file in the package that contains each firmware with version number and a list showing the compatible devices. The descriptor is displayed after loading the LFP file in the LDU.

6. Troubleshooting

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.

6.1. Use Cases

Symptom	Root cause	Action
General video signal problems
Picture is not displayed or distorted	Video connectors are loose	Make sure the connectors fit well.
	Another port is selected in the source/display device	Select the desired/connected port.
	When adaptor cable is applied: the source port does not support the Dual-mode	Extend the picture to a DisplayPort capable display device.
	The monitor is not able to display the desired image resolution	Select another display device or reduce the image resolution.
	Protected image is extended to a non-HDCP capable device	If the monitor does not support displaying HDCP-encrypted image content, try to disable the HDCP (if the content allows).
	The fiber optical connector is unplugged or dirty	Check and clean the connectors carefully if necessary.

6.2. 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 an 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.

7. Technologies

The following sections contain descriptions and useful technical information on how the devices work in the background. The content is based on experiences and cases we met in the practice. These sections help to understand features and technical standards like the following:

7.1. HDCP Management

Lightware Visual Engineering is a legal HDCP adopter. Several functions have been developed that help solve HDCP related problems. Complex AV systems often have both HDCP and non-HDCP components. The matrix allows transmitting both HDCP encrypted and unencrypted signals. The devices will be still HDCP compliant, as they will never output an encrypted signal to a non-HDCP compliant display device. If an encrypted signal is switched to a non-compliant output, a red screen alert or muted screen will appear.

7.1.1. Protected and Unprotected Content

Many video sources send HDCP protected signal if they detect that the sink is HDCP capable – even if the content is not copyrighted. This can cause trouble if an HDCP capable device is connected between the source and the display. In this case, the content cannot be viewed on non-HDCP capable displays and interfaces like event controllers. Rental and staging technicians often complain about certain laptops that are always sending HDCP encrypted signals if the receiver device (display, matrix router, etc.) reports HDCP compliancy. Even though HDCP encryption is not required all the time (e.g. computer desktop image), certain laptops still do that.

To avoid unnecessary HDCP encryption, Lightware introduced the HDCP enabling/disabling function: the HDCP capability can be disabled in the Lightware device. If HDCP is disabled, the connected source will detect that the sink is not HDCP capable, and turn off authentication.

7.1.2. Disable Unnecessary Encryption

HDCP Compliant Sink

All the devices are HDCP-compliant, no manual setting is required, both protected and unprotected contents are transmitted and displayed on the sink.

Not HDCP-compliant Sink 1.

Not-HDCP compliant sink is connected to the matrix. Some sources (e.g. computers) always send HDCP encrypted signals if the receiver device reports HDCP compliancy, however, HDCP encryption is not required all the time (e.g. computer desktop image). If HDCP is enabled in the matrix, the image will not be displayed on the sink.

Setting the HDCP parameter to Auto on the output port and disable HDCP on the input port, the transmitted signal will not be encrypted if the content is not protected. Thus, non-HDCP compliant sinks will display non-encrypted signal.

Not HDCP-compliant Sink 2.

The layout is the same as in the previous case: non-HDCP compliant display device is connected to the matrix but the source would send protected content with encryption. If HDCP is enabled on the input port of the matrix, the source will send encrypted signal.

The sink is not HDCP compliant, thus it will not display the video signal, but blank screen is shown. If HDCP is disabled on the input port of the matrix, the source will not send the signal. The solution is to replace the display device with an HDCP-capable one.

7.2. DisplayPort

DisplayPort is a widely spread audio/video interface standard designed by VESA (Video Electronics Standard Association) in 2006. The aim was to create an interface that would be the connection between graphic cards and display devices. The standard is available and free, thus it can be implemented widely, which could help replace the previously used interfaces, such as VGA or DVI.

Lightware’s DP-OPT extenders are designed according to DisplayPort standard 1.1a. The maximum allowed bandwidth is 10.8 Gbps, which means e.g. 2560x1600 pixel resolution at 60 Hz or 4096x2400 pixels at 30 Hz. Color depth is up to 16 bits per color and 8-channel embedded LPCM audio is supported.

7.2.1. Dual Mode

The mentioned standard was designed to support HDMI/DVI display devices too. If the sink is assembled with DVI or HDMI input connector, it can be connected to a dual mode DisplayPort source by a passive adaptor (DP++). In this case the source switches to DVI/HDMI mode, and the signal is changed to be in line with DVI/HDMI requirements.

INFO:Most of the sources assembled with DisplayPort supports Dual mode, but if you are not sure, check the documentation of your device.

Passive adaptor

A display device with a HDMI or DVI connector can be connected by a passive DP-HDMI or DP-DVI adaptor to the source. The passive adaptor has two functions: sending a sign to the source if DVI or HDMI signal is required, and doing level shifting from +3.3V to +5V. The source switches to DVI/HDMI mode and sends the proper signal.

DP-DVI and DP-HDMI Passive Adaptors

INFO:More information about adaptors can be found in the VESA DisplayPort Interoperability Guideline (www.displayport.org).
