1. Introduction

Thank you for choosing MODEX, the Lightware Modular Extender family. The MODEX family is a hybrid, modular and multi-layer group of extenders supporting AV and broadcast

industry’s formats. Capable of extending digital and analog audio and video, USB KVM,

Ethernet and control signals like RS-232, RS-422 or Infrared.

1.2. Description

The technology built into the MODEX family breaks many standard limitations allowing 30 meters DVI cable on input, Advanced EDID Management, Pixel Accurate Reclocking, LAN and RS-232/RS-422 control.

The half unit extender allows one video & audio module and two interface modules (each can be the same or different type). The front panel has an additional 10/100 Mbps Ethernet port (with full functionality, but can be used as a control interface) and USB KVM connectors (transmitter has one USB-B for the computer; receiver has two USB-A connectors for a keyboard and a mouse). Keyboard and mouse functions are emulated by the extender and no USB enumeration occurs while operator switching.

MODEX includes a family of long distance transmitters and receivers for sending and receiving video, audio, RS-232 and IR control, USB KVM and Ethernet over a single fiber cable. Media connector, the heart of the MODEX determines the signal transportation type as well as the direction (the unit is a transmitter or receiver).

The MODEX is fully compatible with the 25G hybrid architecture.

Except the following media connectors: MODEX-CON-OPTS-NT-PCN and MODEX-CON-OPTM-NT-PCN.

For the following media connectors: MODEX-CON-OPTS-NT-PCN and MODEX-CON-OPTM-NT-PCN.

For the following modules: MODEX-IF-AUDIN and MODEX-IF-AUDOUT (1-1 pc.), MODEX-IF-AUD (2 pcs.)

For the following module: MODEX-IF-RS232-IR

1.3. Features5

 Front panel control – EDID emulation, Network settings, Preset handling and the most important

module settings are available on LCD-based menu with navigation buttons.

 Built-in web page – Easy access from a Web browser to control and configure the MODEX pair.  Built-in universal power supply – The extenders are equipped with a built-in universal power

supply, which accepts AC voltages from 100 to 240 Volts with 50 or 60 Hz line frequency.

 Front panel LEDs – Audio, Video, Optical Link and PSU LEDs to get immediate feedback about the

signals and link status.

 Pixel accurate reclocking – The video output on the receiver has a clean, jitter free signal,

eliminating signal instability and distortion caused by long cables or connector reflections.

 Advanced EDID Management – User can emulate any EDID on video input ports, read out and

store any monitor’s EDID.

 HDCP enable / disable – MODEX extenders are HDCP-capable ones. To display unprotected

content on a non-HDCP capable sink, HDCP can be disabled via the front panel menu or from a web browser by the built-in web page.

 Single fiber technology – MODEX-OPTS and -OPTM extenders give optical transmission over a

single or duplex fiber; equipped with a Neutrik OpticalCON or industrial grade connector but both can be used with LC fiber cable.

 USB K+M – Connected USB HID devices (e.g. keyboard, mouse) are extended from transmitter to

receiver thus a computer can be remote controlled.

2.6.10. Neutrik power connector

MODEX-CON-OPTS-NT-PCN and MODEX-CON-OPTM-NT-PCN media connectors are assembled with special Neutrik power connector, NAC3MPA-1 (Power In). It ensures a very rugged solution in combination with a locking device in order to guarantee a safe power connection.

Important! PowerCON is a connector without breaking capacity; it should not be connected or

disconnected under load or live!

After plugging it in, turn the plug clockwise; to disconnect, first pull the latch backward, turn the plug counterclockwise and unplug the connector.

Figure 2-4. Locking and unlocking Neutrik power connector

Supplied power cable

The cable is assembled with NAC3FCA Neutrik power connector (Power In) with white chuck that fits for thin cables (diameter between 6.0 and 11.0 mm). A black-colored chuck is also supplied that fits for thick cables (diameter between 9.5 and 15.0 mm).

Assembling

Important! Cable assembling can be only done by qualified person!

If the cable needs to be replaced, the following steps help when assembling:

Step 1. Put bushing and chuck onto the cable. Step 2. Prepare cable. Step 3. Insert the wire into the terminals and fasten the clamping device by a flat screw

driver.

Step 4. Push insert and chuck into housing (pay attention to the guiding keyway!) Step 5. Fasten bushing by means of a fork wrench 3/4”, min. Torque 2.5 Nm.

3.1. Understanding EDID

3.1.1. 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.

Figure 3-1. EDID communication

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 EEDID 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.

3.1.2. Common problems related to EDID

Problem: „I have changed to a different EDID on MODEX-OPTS-TX 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 MODEX-OPTS-TX 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 that supports all common VESA resolutions; see the factory EDID list in section 4.3.2 on page 24.

Page 20

Page 20 / 90 Section 3. Technologies

3.2. 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.

MODEX transmitters provide Lightware’s Advanced EDID Management function that helps system integration. The transmitter’s built-in EDID memory stores and emulates more than 100 EDID data (factory presets and user memory, the exact number depends on the firmware) plus the monitor's EDID that is connected to the receiver’s output connector. MODEX stores the EDID of the attached monitor or projector in a non-volatile memory. This way the EDID from a monitor is available when the monitor is unplugged, or switched off.

The EDID emulated on the DVI input can be copied from the transmitter's memory (static EDID emulation), or from the last attached monitors memory (dynamic EDID emulation). For example, the transmitter can be set up to emulate a device, which is connected to the receiver’s DVI output. In this case the EDID automatically changes, if the monitor is replaced with another display device (as long as it has a valid EDID).

Advanced EDID management can be controlled by the front panel’s control buttons and via the built-in webpage.

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.

Info: When EDID has been changed, the transmitter toggles the HOTPLUG signal for 2 seconds.

Some sources do not observe this signal, so in this case the change is not recognized by the source. In such cases the source device must be restarted or powered OFF and ON again.

3.3. HDCP management

Lightware Visual Engineering is a legal HDCP adopter, and has developed several functions that helps to solve HDCP related problems. Complex AV systems often have both HDCP and non-HDCP components. MODEX extenders allow to transmit 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 should be switched to a non-compliant output, it will show a red screen alert or will be muted.

3.3.1. 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 a HDCP capable device (e.g. an extender-pair) is connected between the source and the display. In this case the content can’t be viewed on non-HDCP capable displays and interfaces like event controllers.

Rental and staging technicians often complain about Apple laptops, who always send HDCP encrypted signals if the receiver device (display, matrix router, etc.) reports HDCP compliancy. However HDCP encryption is not required all the time (e.g. computer desktop image) MacBook and MacBook Pro still do that.

To avoid unnecessary HDCP encryption, Lightware introduced the HDCP enabling/disabling function: the HDCP capability can be disabled on the extenders. If HDCP is disabled, the connected source will detect that the sink is not HDCP capable, and turn off authentication. The source will not be able to communicate with any of the devices

(displays, repeaters, etc.) that are connected to the receiver’s output, therefore it could not

see if they are HDCP capable or not.

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

Non-HDCP-compliant sink (HDMI/DVI) 1.

Figure 3-3. Non-HDCP compliant sink displaying unprotected content

Non-HDCP compliant display device is connected to the receiver. 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 extenders, the image will not be displayed.

On MODEX extenders HDCP mode can be set to Auto. In this case the transmitted signal will not be encrypted if the content is not protected. Thus non-HDCP compliant sinks will display non-encrypted signal.

Non-HDCP-compliant sink (HDMI/DVI) 2.

Figure 3-4. Non-HDCP compliant sink and protected content

The layout is the same as in previous case: non-HDCP compliant display device is connected to the receiver. Now the difference is that the content is protected, thus the

source is sending encrypted signal. In this case the extenders’ HDCP setting has no effect:

the source sends encrypted signal, since the content is protected. The display device will show blank red, muted screen or pop up an error message that the sink is not HDCPcompliant. The solution is to replace the display device to a HDCP-capable one.

4.1. Module code sequence

Each MODEX unit has a 15-character-long code sequence which identifies the modules built in the frame. The code sequence consists of 5x3 blocks of characters. The 3-character-long blocks are the last three characters of a module’s part code (this code is also painted on the module/frame).

The following example represents the structure of the code sequence:

The module code – that is displayed in idle state – of above MODEX unit is:

103: (9161 0103) MODEX-OPTS-TX Frame 227: (9161 0227) MODEX-CON-NT-OPTS Media connector 410: (9161 0410) MODEX-AV-HDMI-DVI-4K-IM Video & Audio Module (B) 715: (9161 0715) MODEX-IF-RS232-IR Interface Module (E) 721: (9161 0721) MODEX-IF-AUD Interface Module (D)

Info: The order of the modules and codes are determined by Lightware.

4.2. Module layout

The layout of the modules is fixed so as the order of the module codes. B, D and E letters determine the module positions which help to identify them in LW3 protocol.

C means the physical module (PHY), which is integrated into the Core module in MODEX-OPT extenders.

The letters are also displayed in the built-in website in the Settings menu, Status submenu, see section

4.3. EDID memory (transmitter)1

EDID memory is non-volatile and consists of four blocks, each for different purposes:

 Factory preset EDIDs  User-saved EDIDs  Dynamic EDID (EDID of last connected sink on the output port)  Emulated EDIDs (EDID currently emulated on a specific input port)

EDIDs are numbered from 1 in each block. They can be referred as the first letter of the block name and the number of the desired EDID. This way F02 refers to the second factory preset EDID.

Dynamic and emulated EDID blocks’ size depends on the A/V modules. EDID memory structure is the following:

 F01..F119 .................................................................. Factory Preset EDIDs

 U01..U31 ..................................................... User programmable memories

 Dxx .................................................. Last attached monitor’s EDID (output)

 Exx ........................................................................... Emulated EDID (input)

Dynamic, factory and user EDIDs can be switched and emulated at the input(s).

Info: Factory EDIDs (Fxx) are factory preprogrammed and cannot be modified. These are the

most commonly used resolutions. Info: MODEX can handle both 128 Byte EDID and 256 Byte extended EDID structures. Info: Attached monitor’s EDID is stored automatically, until a new monitor is attached to that

particular output. In case of powering the unit off, last attached monitor’s EDID remains in

non-volatile memory even if the monitor is disconnected.

4.3.1. EDID types

Most of the factory preset EDIDs include only one resolution. This is to force the connected

source to give a signal with the needed resolution. However there are Universal EDIDs as

well which allow many resolutions.

Factory EDIDs are divided into groups regarding their type. Some EDIDs support DVI only,

some support HDMI and some are for analog VGA signals. Also there are EDIDs for Dual

Link DVI resolutions.

DVI EDIDs does not support audio. Universal DVI EDID indicates support for many PC

(VESA) resolutions.

HDMI EDIDs support embedded audio. These EDIDs have PCM stereo audio format

enabled. To allow other audio formats like Dolby and DTS, special EDIDs have to be used.

There are three Universal HDMI EDIDs which include the same resolutions but support

different capabilities:

EDID

Table 4-1. Universal HDMI EDIDs

Info: Analog EDIDs are for future developments.

Dual Link DVI EDIDs does not support audio. Use only for Dual Link ports.

The exact EDID memory size depends on the firmware and the installed A/V modules.

4.4. USB K+M

MODEX devices are able to extend two USB 1.1 and/or USB 2.0 devices from the

transmitter to the receiver that are compatible and in line with USB HID standard. Typical

supported USB devices are:

 USB mouse and keyboard,  Smart Card (reader).

Typical application is when a computer located at the transmitter is controlled at receiver’s

side by the connected keyboard and mouse via USB. Certain touch monitors fulfill the USB

HID standard, which can also be connected.

Below listed devices have been tested and found compatible by Lightware:

 Touch Revolution K17A-0101-A0 (VID:0x0EEf PID:0x72C4),  Dell ST2220T (VID:0x1FD2 PID:0x0064),  LG 23ET83V (VID:0x0457 PID:0x1030) – currently one point touch is supported,  ZYTRONIC (VID:0x14C8 PID:0x0005) and  Wacom intous5 tablet.

5.1. Connecting devices

When building an electronic system, make sure that all devices are powered down before

connecting them. Powered on devices may have dangerous voltage levels that can

damage sensitive electronic circuits. After the system is complete, connect the power

cables to the extenders and to the power outlet; the units are immediately powered ON.

Info: Do not connect more than one port of a MODEX to the same LAN to avoid loops. In the

same way; if a MODEX transmitter and a receiver are linked by fiber optical cable, do not

connect both to the same LAN, only one of them.

Figure 5-1. Connecting devices

Step 1. Connect the transmitter and the receiver by a multi- or single mode fiber cable.

Connect channel A on transmitter to channel B on receiver.

Step 2. Connect a DVI or HDMI source (e.g. computer) to the transmitter's DVI or HDMI

INPUT connector.

Step 3. Connect a DVI or HDMI sink (e.g. projector) to the receiver's DVI or HDMI output.

Step 4. Optionally connect the transmitter or the receiver to a Local Area Network in order

to control the devices by the built-in Web page. More information about establishing the connection can be found in section 7 on page 36.

5.2. Serial devices

5.2.1. General information about serial communication

There are two kind of devices in general serial communication from our aspect:

Data Terminal Equipment (DTE)

DTE is an end-instrument that converts user information into signals or reconverts received

signals. Typical DTE devices: computers, LCD touch panels, control systems.

Data Circuit-terminating Equipment (DCE)

DCE is device that sits between the DTE and a data transmission circuit. It also called data

communication equipment and data carrier equipment. Typical DCE devices: projectors,

industrial monitors and amplifiers.

Among others the pin assignment is different between DTE and DCE and different type of

serial cables have to be used between the serial devices.

7. Web control – Using the built-in website

MODEX extenders have several configuration options. More settings are available using the built-in website than on the front panel. Connection can be established to the website through any Ethernet connector of the MODEX.

Network structure

MODEX extenders have a front panel Ethernet port. Additional rear-side Ethernet connectors are available on MODEX-IF-ETH interface module. All the connectors and the controller entity belong to the same network inside the MODEX. Ethernet link is also transferred to the connected pair via physical layer link. Connect any RJ45 connector of the transmitter or the receiver to a LAN and you can control both units.

Info: Do not connect more than one port of a MODEX to the same LAN to avoid loops. In the

same way; if a MODEX transmitter and a receiver are linked by fiber optical cable, do not connect both to the same LAN, only one of them.

7.1. IP settings

Before you connect to a MODEX extender using a Web browser the IP address must be set. The Ethernet port can be configured on the front panel LCD menu or remotely through the built-in website. There are three different ways to configure the IP address.

Set the factory default static IP address

MODEX extenders have static IP settings at the first startup. You can reload these settings to the default state by the LCD menu (Settings / System / Factory Default). For detailed information about this step see section 6.3.1 on page 30. Factory default IP addresses are described in section 10.5.1 on page 87.

Set a user-defined static IP address

IP address, Subnet mask and Static gateway can be set by the user on front panel LCD menu (Settings / Network Settings). For detailed information about this step see section

6.3.1 on page 30.

Set a dynamic IP address

DHCP mode can be enabled on the front panel LCD menu (Settings / Network Settings / DHCP). The extenders acquire IP addresses from the DHCP server on the LAN in this case. For detailed information about this step see section 6.3.1 on page 30.

Port settings

Port setting has no influence on the connection if the built-in web is used to control the MODEX. When the extender is connected by LAN, port nr. 80 and 81 are used which cannot be changed.

Info: Port setting has an influence when firmware upgrade is performed.

7.2. Establishing the connection

To connect to a MODEX launch a web browser and type the IP address. You can verify the actual address of the MODEX unit on its front panel display (Settings / Network).

Info: Built-in webpage can be opened at most in 4 different browser tabs simultaneously.

System requirements

Operating System: Microsoft Windows XP, Windows Vista, Windows 7, Mac OS X, or Linux.

7.4.1. Video crosspoint

The number of the inputs and the outputs are depending on the number and the direction of the video modules. As MODEX supports only one video transmission over the link, the link appears as an input or as an output depending on the direction of the extender.

At the transmitter side the link appears as an output. At the receiver side the link appears as an input.

Figure 7-1. Video crosspoint (Transmitter)

Example

Above figure shows one input and one output. HDMI is the input port and the output port is the fiber optical connector – towards to the receiver. In this case there is no real crosspoint switching, the signal of the input port is always switched to the output port (except if the output is muted).

7.4.2. Audio crosspoint

MODEX extenders support two audio groups: the Main audio group and the S/PDIF audio group. These groups are independent from each other. In this case there are forbidden crosspoint connections. The link can support four audio layers:

Main audio group:

 Embedded audio (from transmitter to receiver)  Return AUX (from receiver to transmitter)

S/PDIF audio group:

 Forward Audio (from transmitter to receiver)  Return Audio (from receiver to transmitter)

At the transmitter side the Embedded audio and the Forward Audio appears as an output, the Return Audio and the Return AUX appears as an input. At the receiver side the direction is the opposite.

Figure 7-2. Audio layers

The four audio layers, between the transmitter and the receiver are defined and fixed, always extended. The other audio inputs and outputs are optional and depend on the installed interface modules; the available crosspoint settings depend on the application mode set in the properties of the audio module.

Example

Above screenshot was made of a MODEX transmitter’s Audio crosspoint layout (assembled with MODEX-IF-AUD module). Settings are according to section 7.5.3.1 on page 44.

The following connections are established:

 HDMI audio input port is switched to Analog Output and to Embedded audio,  S/PDIF input port is switched to S/PDIF output port,  Return audio is switched to Forward audio.

Info: To have the desired audio crosspoint setup, check the settings in both extenders.

7.4.3. Infra crosspoint

The number of the available ports in a unit is determined as follows: Number of inputs = Number of inputs [local unit] + Number of inputs [remote unit] Number of outputs = Number of outputs [local unit] All infrared inputs are transmitted to the remote device all the time. As the data of all infra

input ports can be transmitted via the link, the link does not appear as an output as it appears in the video or in the audio crosspoints. The input port with a link icon symbolizes the input of the remote side.

Info: The selection should be done on the local device which infra source(s) has/have to be

output on a local infra port.

Info: The signal of the local input port is always extended via the fiber optical cable, but the other

device’s Infra crosspoint settings determine if the incoming signal is switched to its IR

output port or not.

Further examples:

Example 1

IR signal received via fiber optical cable is switched to the IR output port. Local IR input signal is extended via fiber optical cable.

Example 2

IR signal of local input port and IR signal received via fiber cable are mixed on each other and switched to the IR output port. Local IR input signal is extended via fiber optical cable.

Example 3

Only local IR input signal is transmitted to the other extender.

7.4.4. Serial crosspoint

The number of the available ports in a unit is determined as follows: Number of inputs = Number of the ports [local unit] + Number of the ports [remote unit] Number of outputs = Number of the ports [local unit] In crosspoint view every serial port appears as an input and an output. It means that Tx

data channel of the port is an input and Rx data channel is an output – within one port. All serial inputs are transmitted to the remote device all the time. As all serial ports data

can be transmitted via the link, the link does not appear as an output as it appears in video or in audio crosspoints. The input port with a link icon symbolizes the input of the remote side.

Info: The serial source switched to the local output can be selected on the local device.

If an input is switched to an output, and both the input and the output belongs to the same serial port connector, that results an internal loopback. This way the serial link can be tested between the source and the MODEX extender device.

Figure 7-7. Serial crosspoint

Example

The working method is the same as for Infra crosspoint settings. Above screenshot was made about a Serial crosspoint layout of a MODEX (assembled

with MODEX-IF-RS232-IR module). Local UART input signal (on Rx data lane) and the signal received via fiber optical cable are switched to the UART output port (Tx data lane) within the given module. Local UART input signal is extended also to the other MODEX.

Info: The signal of the local input port is always extended via the fiber optical cable, but the other

device’s Serial crosspoint settings determine if the incoming signal is switched to its UART

output port or not.

Further examples:

Example 1

Signal received on local UART port (Rx data lane) is switched to the Tx data lane of the port and extended to the other MODEX as well.

Example 2

Signal received via fiber optical cable is switched to the local UART port (Tx data lane). Signal received on local UART port (Rx data lane) is extended to the other MODEX.

Example 3

Signal received on local UART port (Rx data lane) is extended to the other MODEX.

7.4.5. Preset settings

Each MODEX extender has eight preset memories that can be used to store settings and configurations of the MODEX. Click on the Presets button in the right top corner to display the Presets window.

Info: A preset setting stores the full configuration of all modules, ports and system settings. EDID

data is not stored, but the ID number of the emulated EDID is saved – for every input port.

User’s Manual

Section 7. Web control – Using the built-in website Page 43 / 90

Saving a preset

Step 1. Create the desired crosspoint connections, port and module settings. Step 2. Select Crosspoint view and click on Presets button. Step 3. Select the desired preset memory from the dropdown menu. Step 4. Optionally write a short description and store it by the Set button (description can

be also stored without saving/loading a preset).

Step 5. Click on Save preset button.

Loading a preset

Step 1. Select Crosspoint view and click on Presets button. Step 2. Select a preset from the dropdown menu. Step 3. Optionally mark or unmark the ‘Applying this preset will remove all locks’ setting. Step 4. Click on Load preset button.

Info: Loading a preset does not change User EDID memory. Info: If a place in the User EDID memory has been changed after saving the preset, the EDID

itself will not be changed when loading the preset. The new EDID saved in the place will be valid, since a preset stores the ID number of an emulated EDID, not the EDID data.

7.5. Module properties and settings

General

General information is displayed about the module: Module name, Part number, Hardware version, Serial number and further module-dependent information and settings.

7.5.1. Optical link quality

The properties panel of MODEX-PH-OPTx module contains a feature that gives information about the optical link quality between the transmitter and the receiver. (Scroll down in the window and the section will be visible.) If the radio button is checked, link quality measurement is in progress (data is collected in the background). If the button is unchecked, error counter is reset to 0.

Info: If the module (MODEX-PH-OPTx) is locked, link quality measurement cannot be enabled

or disabled.

7.5.2. Video modules

MODEX modules – including video-, interface- and physical link modules – have their special property list. Related ports are indicated by the color of the module property bar. Different color means different module. Left click on Module property bar to open module property window.

Certain video modules have more than one video inputs or outputs, but only one of these inputs or outputs can be used in video crosspoint. The reason is that only one video stream transmission is permitted between the core module and the video module. Under Settings there is a Mode selector which activates the interface. The active input or output port of selected mode appears in video crosspoint and the port property becomes available.

Info: If the module is locked, the active interface cannot be changed.

7.5.3. Audio modules

Each MODEX modules – including video-, interface- and physical link modules – have their special property list. Related ports are indicated by the color of the module property bar. Different color means different module. Left click on Module property bar to open module property window.

There is a mode selector under Settings of Audio modules. Each audio port can be assigned to one of the two audio groups (Main or S/PDIF) using mode function. After setting the mode of the audio interface module, the supported input and/or output port of the selected mode appears in audio crosspoint and the port property window becomes available.

Info: This setting can be set in the transmitter and in the receiver separately. Info: If the module is locked, the audio interface mode cannot be changed.

7.6. Port properties and settings

Left click on Port property icon to open Property window. The physical port, the input and the output ports have different property windows. Status information about the port and signal information about incoming and outgoing signals are displayed in the property window. At the same time it gives the opportunity to set parameters, rename a port or access special functions – e.g. Frame detector at input port side.

Muting (only on output ports)

Outputs can be easily muted by clicking on the button Unmuted. If the output is muted, button text is Muted. When a port is muted, no signal is present on the output.

Locking (only on input ports)

Outputs can be easily locked by clicking on the button Unlocked. If the output is locked, button text is Locked.

Info: If the port is locked, its mute state cannot be changed neither by the button, nor by loading

a preset.

Port name

The name of a port can be changed by typing the new name and clicking the Set button. The change will be visible on the port button and on front panel menu.

The following characters are allowed when naming: Letters (A-Z) and (a-z), hyphen (-), underscore (_), numbers (0-9) and dot (.).

Frame detector (on video input ports)

Input ports can show detailed information about the signal like blanking intervals and active video resolution. This feature is a good troubleshooter if compatibility problems occur during system installation. To access this function, open parameter window for the input port on which the signal has to be checked. Click on Frame Detector button to show detailed timings.

Figure 7-9. Frame detector window

Lightware’s frame detector function works like an input signal analyzer and makes possible

to determine the exact video format that is sent by the source, thus helps to identify many problems. E.g. actual timing parameters may differ from the expected and this may cause some displays to drop the picture.

Frame detector measures detailed timings on the matrices’ incoming video signals just like a built-in oscilloscope, but it is much more easy to use. Actual display area shows the active video size (light grey). Dark gray area of the full frame is the blanking interval which can contain the info frames and embedded audio data for HDMI signals. Shown values are measured actually on the signal and not retrieved only from the HDMI info frames.

8.1. LW3 protocol – Overview

Lightware 3 (LW3) protocol is currently used by MODEX extender family, 25G product line and will be the preferred protocol in new developments.

LW3 is an ASCII based protocol and all commands are terminated with a carriage return (Cr, ‘\r’) and line feed (Lf, ‘\n’) pair. It is organized as a tree structure that provides outstanding flexibility for implementing a human readable, but still easy to programmatically parse protocol, which is suitable for different products with different feature list.

The concept

In order to implement a flexible, easy-to-use protocol that is straightforward to adapt to new devices and provides outstanding scalability and sustainability, Lightware decided to organize all settings, parameters and properties of the device to a tree structure with ‘nodes’, ‘properties’ and ‘methods’.

8.1.1. Elements of tree structure

Info: All names and values are case sensitive. Space character is replaced by ‘●’ character in

elements and commands descriptions.

Node

 Basic building block of the tree structure is the ‘node’.  A node can have multiple child nodes, but only one parent.  The tree has only one root: the ‘root node’.  The leaves of the tree are also nodes, which do not have child nodes.  Nodes are separated by a slash (‘/’) character; no backslash is used.  The identifier of the root node is a slash (‘/’).  Nodes’ name can contain elements of the English alphabet and numbers.

 The path of a node has to contain all parent nodes from the root node.

Format (the root node): nX●/ Path: nX●/[nodeName]/[nodeName]/[nodeName] Legend: ‘n’: node ‘X’ can be:

‘-’: default for a node, ‘m’: manual for the node (see section 8.2.9 on page 66), ‘E’: error message for the node (see section 8.1.3 on page 61).

Info: All parent nodes must be listed in the path of a node.

Page 59

MODEX-OPTS, MODEX-OPTM

User’s Manual

Section 8. Programmer’s reference Page 59 / 90

Following example presents the depth tree traversal of Figure 8-1:

Figure 8-1. Tree structure of nodes

Property

The ‘property’ in the LW3 protocol is basically a leaf, which has a well-defined value.

 A property has a value.  A property cannot have child nodes or child properties. It is always a leaf.  A node can have any number of properties (may not have any).  A property is referenced with a dot (‘.’) after the node name.  The properties’ name can contain the elements of the English alphabet, numbers

and underscore (‘_’) character.

 By convention, properties are beginning with capital letter, all other characters are

lowercase ones. In case of compound words, all words are beginning with a capital letter (CamelCase).

 The value of the property can contain any readable ASCII character (the control

characters have to be escaped, see section 8.1.2 on page 60).

 A property can be read-only or read/write.

Format: pX●/[nodeName].[propertyName]=[propertyValue] Legend: p: property

X can be: ‘r’: if the property is read-only. ‘w’: if the property is readable, writable. ‘m’: manual for the property (see section 8.2.9 on page 66). ‘E’: error message for the property (see section 8.1.3 on page 61).

Example:

Method

‘Method’ in the LW3 protocol is also a leaf. It cannot have a value, such as the properties, but it can be invoked with a parameter with the help of a special ‘CALL’ command (see section 8.2.5 on page 64).

 A method cannot have child nodes or child methods. It is always a leaf.  A node can have any number of methods (may not have any).  A method is referenced with a colon (‘:’) after the node.  Methods’ name can contain the elements of the English alphabet, numbers and

underscore (‘_’) character.

 By convention, methods are beginning with lowercase letter. In case of compound

words, the very first letter is lowercase, and the first letter of each other words are capitalized (lowerCamelCase).

 The parameter of the method can contain any readable ASCII character (control

characters have to be escaped, see section 8.1.2 on page 60).

 The method always has a return ‘state’ if the method could be executed. The state

could be either ‘OK’ or ‘FAILED’.

 The method not necessarily has a return ‘value’. If it does, it can contain additional

information, which is always specific for the current case (return value can specify why the execution failed). Find details in section 8.2.5 on page 64.

 When the method cannot be executed (e.g. the parameter list is illegal), there is

an error message (see section 8.1.3 on page 61).

Format: mX●/[nodeName]:[methodName]=[returnValue] Legend: m: method

X can be: ‘O’: when the execution of the method was successful, ‘F’: when the execution of the method failed, ‘m’: manual for the method (see section 8.2.9 on page 66), ‘E’: error message for the method (see section 8.1.3 on page 61).

Example:

< mO●/node1/node12:method1 < mO●/MEDIA/IR/XP1:DefaultSwitch < mO●/EDID:DeleteEdid

8.1.2. Escaping

Property values and method parameters can contain characters that are used as control characters in the protocol. They must be escaped. The escape character is the backslash (‘\’) and escaping means injecting a backslash before the character that should be escaped (like in C language).

Control characters are the followings: \ { } # % ( ) \r \n \t

Example:

Original text: John●(Doe).●#3:●5%2=1●node1\node11 Escaped text: John●\(Doe\).●\#3:●5\%2=1●node1\\node11

Section 8. Programmer’s reference Page 61 / 90

8.1.3. Error messages

There are several error messages defined in LW3 protocol. All of them have a unique error number which can be used programmatically, and an informative error message.

Format: XE●[primitive]●%EYYYY:●[Error message] Legend: X can be:

‘-’: syntax error. Cannot parse the command at all. ‘n’: node error. ‘p’: property error. ‘m’: method error. YYY: error code, which can be one of the followings: E001 Syntax error E010 Illegal parameter count E002 Node not found E011 Item already exist E003 EOL expected E012 Item does not exist E004 Writing read-only property E013 Illegal operation E005 Invalid value E014 Internal error E006 Property does not exist E015 Access denied E007 Syntax error E016 Write access denied E008 Illegal method E017 Reserved E009 Method does not exist E018 Waiting timeout

8.1.4. Prefix summary

The following prefixes are defined in LW3 protocol: ‘n-’: a node, ‘nE’: an error for a node, ‘nm’: a manual for a node, ‘pr’: a read-only property, ‘pw’: read-write property, ‘pE’: an error for the property, ‘pm’: a manual for the property, ‘m-’: a method, ‘mO’: a response after a success method execution, ‘mF’: a response after a failed method execution, ‘mE’: an error for a method, ‘mm’: a manual for a method.

Page 62

Page 62 / 90 Section 8. Programmer’s reference

8.2. Commands

Getter

The ‘GET’ command can be used to get subnodes, properties and methods of a specific node. It also can be used to get the value of a property.

Response format

The first two characters of a response are unambiguously identifies the type of the element that the response line concerns. First character is the type of the element (node/property/method), second is for miscellaneous information (e.g. read/write rights).

Defined prefixes are: ‘n-’: node ‘pr’: property – only readable ‘pw’: property – writable, readable ‘m-’: method executable After prefix the response contains the full path of the node, property or method after a space

character.

8.2.1. Get all children of a node

Get all of the child nodes of a parent node, with one GET command.

Command format: GET●[nodePath] Response format: n-●[nodePath] Example:

> GET●/MEDIA/IR

< n-●/MEDIA/IR/XP1 < n-●/MEDIA/IR/P1 < n-●/MEDIA/IR/P2

8.2.2. Get all properties and methods of a node

Get all properties and methods of a specific node, with one GET command, using an asterisk wildchar.

Command format: GET●[nodePath].* Response format: (for properties)

pX●[nodePath].[propertyName]=[parameter] Legend: X can be: ‘r’: read-only ‘w’: read-write Response format: (for methods) m-●[nodePath]:[methodName]

Example:

> GET●/PRESETS/1.*

< pr●/PRESETS/1.Index=1 < pw●/PRESETS/1.RemoveLock=false < pw●/PRESETS/1.Text=Preset 1

Page 63

MODEX-OPTS, MODEX-OPTM

User’s Manual

Section 8. Programmer’s reference Page 63 / 90

8.2.3. Get all child nodes, properties and methods of a node

Get all child nodes, properties and methods of a node with one command, without using a wildchar.

Command format: GETALL●[nodePath] Response format: (for nodes)

n-●[nodePath] Response format: (for properties) pX●[nodePath].[propertyName]=[parameter] Legend: X can be: ‘r’: read-only ‘w’: read-write Response format: (for methods) m-●[nodePath]:[methodName]

Example:

> GETALL●/MANAGEMENT

< n-●/MANAGEMENT/NETWORK < n-●/MANAGEMENT/STATUS < n-●/MANAGEMENT/LOCK < n-●/MANAGEMENT/LOG

< pr●/MANAGEMENT.rebootNeeded=false < pw●/MANAGEMENT.WebEnvironment=

< m-●/MANAGEMENT:Udc < m-●/MANAGEMENT:Msg

Info: The command does not list child nodes and properties of listed child nodes, only that

belongs to the node directly. E.g. the child nodes and properties of /MANAGEMENT/NETWORK is not listed in this example, those can be queried if ‘GETALL●/MANAGEMENT/NETWORK’ is run.

8.2.4. Set command

The setter command can be used to modify the value of a property.

Command format: SET●[nodePath].[propertyName]=[newPropertyValue] Response format:

The response for setting a property to a new value is the same as the response for ‘GET’ command. The value in the response is the new value if the execution of ‘SET’ command was successful, otherwise the unmodified ‘old value’ with an error message.

pw●[nodePath].[propertyName]=[newPropertyValue]

Example:

> SET●/MANAGEMENT/NETWORK.PortNumber=6107

< pw●/MANAGEMENT/NETWORK.PortNumber=6107

Error response format:

If there were errors during setting a property, an error message follows the unmodified property value. Find the error numbers in section 8.1.3 on page 61.

pE●[nodePath].[propertyName]=[umodifiedValue]●%EXXX:Error message

Legend:

XXX: error number (see section 8.1.3 on page 61).

Page 64

Page 64 / 90 Section 8. Programmer’s reference

Examples:

> SET●/SYS/CORE/B/VIDEODVOOO.HdcpEnable=false

< nE●%E002:Node not found

> SET●/SYS/CORE.PartNumber=12345678

< pE●%E004:Writing read-only property

> SET●/SYS/CORE/B/VIDEODVI.HdcpEnable=falssss

< pE●%E005:Invalid value

> SET●/SYS/CORE/B/VIDEODVI.HdcpEnab=false

< pE●%E006:Property not exists

8.2.5. Invocation

A method can be invoked with the help of ‘CALL’ command.

Command format: CALL●[nodePath]:[methodName]([parameter]) Response format:

The response for a method execution is a state and a value. The state is mandatory and always defined, if the method could be executed. It can be either a success or a failure. The value is optional and it can contain additional information – such as the reason why the state is a failure or a specific value when the state is success – which the client can process. It is also possible to get an error message, when the method could not be executed – e.g. the parameter was illegal – and hence not even the state of the execution could be specified.

mX●[nodePath]:[methodName]=Y Legend: X can be: ‘O’: if the execution is successful. ‘F’: if the execution is failed, but the method could be executed. ‘E’: if the method could not be executed: e.g. illegal parameter count. Y can be:

 the return value of the method if any.  it is valid that a method does not have any return value. In this case the

equal sign (‘=‘) can be omitted.

Example:

> CALL●/MANAGEMENT/LOCK:LockAll()

< mO●/MANAGEMENT/LOCK:LockAll

Error response format:

If there were errors during the execution, an error message is received, which follows the method name. Find the error numbers in section 8.1.3 on page 61.

mE●[nodePath]:[methodName]●%EXXX:Error message

Example:

> CALL●/EDID:DeleteEdid(U100)

< mE●%E005:Invalid●value

8.2.6. Subscription

User can subscribe to any node. Subscribe to a node means that user will get a notification if any of the properties of the node is changed. These notifications are asynchronous messages – such as the ones described above – and hence they are useful to keep client application up-to-date, without receiving any unwanted information. When user does not want to be informed about the changes anymore, he can simply unsubscribe from the node.

Page 65

MODEX-OPTS, MODEX-OPTM

User’s Manual

Section 8. Programmer’s reference Page 65 / 90

Info: The subscriptions are handled separately for connections and not for users. Hence, if the

connection is terminated all registered subscriptions are deleted. After every connection the subscribe command has to be sent in order to get the notifications of the changes.

Subscribe to a node

Command format: OPEN●[nodePath] Response format: o-●[nodePath] Example:

> OPEN●/MANAGEMENT/NETWORK

< o-●/MANAGEMENT/NETWORK

Subscribe to multiple nodes

In order to subscribe to multiple nodes, asterisk wildchar can be used.

Command format: OPEN●[nodePath]/* Response format: o-●[nodePath]/* Example:

> OPEN●/MANAGEMENT/LOG/*

< o-●/MANAGEMENT/LOG/*

Get the active subscriptions

Issuing an ‘OPEN’ command without any parameters returns the active subscriptions for the current connection.

Command format: OPEN Response format: o-●[nodePath] Example:

> OPEN

< o-●/SYS/CORE < o-●/MEDIA/VIDEO < o-●/MEDIA/AUDIO < o-●/MEDIA/IR < o-●/MEDIA/UART

Unsubscribe from a node

Command format: CLOSE●[nodePath] Response format: c-●[nodePath] Example:

> CLOSE●/MANAGEMENT/LOCK

< c-●/MANAGEMENT/LOCK

Unsubscribe from multiple nodes

In order to subscribe to multiple nodes, asterisk wildchar can be used.

Command format: CLOSE●[nodePath]/* Response format: c-●[nodePath]/*

Example:

> CLOSE●/MANAGEMENT/*

< c-●/MANAGEMENT/*

Page 66

Page 66 / 90 Section 8. Programmer’s reference

8.2.7. Notifications about the changes of the properties

When the value of a property is changed and the user is subscribed to the node, which the property belongs to, an asynchronous notification is generated. This notification is called as the ‘change message’. The format of such a message is very similar to the response for ‘GET’ command.

Format: CHG●[nodePath].[propertyName]=[newPropertyValue] Example:

CHG●/MEDIA/IR.P1=IR Input

8.2.8. Signature

For some command the response can contain multiple lines. Every line is terminated with a carriage return (Cr, ‘\r’) and line feed (Lf, ‘\n’) characters. In several cases the number of the lines in the response cannot be determined in advance. In several cases the client is intended waiting for the whole response and also wants to be sure, that received lines belong together and to the same command. In these cases a special feature the ‘signature’ can be used.

The signature is a four-digit-long hexadecimal value that can be optionally placed before every command. In that case, the response to that particular command will also be preceded by the signature, and the corresponding lines will be in between brackets.

Command format: XXXX#[command] Legend: xxxx: four-digit-long hexadecimal value. Response format:

{XXXX [command lines] }

Example:

> 0001#GET●/MEDIA

< {0001 < n-●/MEDIA/VIDEO < n-●/MEDIA/AUDIO < n-●/MEDIA/UART < n-●/MEDIA/IR < n-●/MEDIA/PACKETROUTER < }

Info: The lines of the signature are also Cr and Lf terminated.

8.2.9. Manual

For every property and method in the tree there is a manual. The manual is a human readable text that describes the syntax and provides a hint for how to use the primitives.

Command format:

for property: MAN●[nodePath].[propertyName] for method: MAN●[nodePath]:[methodName]

Response format:

The human readable manual is separated by a space (‘ ‘) character from the primitives. for properties: pm●[nodePath].[propertyName]●Human readable manual for methods: mm●[nodePath]:[methodName]●Human readable manual

Example:

> MAN●/PRESETS.Count

< pm●/PRESETS.Count:[int] Number of presets

> MAN●/SYS/CORE:ResetLink

< mm●/SYS/CORE:ResetLink:Reset optical link.

8.3. LW3 protocol tree

The tree structure of each MODEX is the following:

/ (root node)

/REMOTE (if remote device is connected) /PRESETS /MANAGEMENT /EDID /MEDIA /SYS

8.3.1. /REMOTE

The node contains the protocol tree of the remote device (if connected): PRESETS, MANAGEMENT, EDID, MEDIA and SYS subnodes. Settings and values are valid for the remote device only.

8.3.2. /PRESETS

Group node for the eight available presets; each preset has own subnode with its properties.

8.3.3. /MANAGEMENT/

A group node for every management related settings. The features and settings here are not related to the current crosspoint settings. The node contains the following subnodes:

/MANAGEMENT/NETWORK

Contains Network-related properties, such as IP address, Gateway, Subnet mask, DHCP and Port settings.

/MANAGEMENT/STATUS

Basic status values are stored about the MODEX: Firmware versions, Internal Voltage values, Module code, System time (elapsed time since last booting in seconds).

/MANAGEMENT/LOCK

Installed modules can be locked/unlocked individually or together.

Info: The locking state is also stored under /SYS/CORE nodes and its subnodes (as read-only

property), but the settings can be done in /MANAGEMENT/LOCK.

/MANAGEMENT/LOG

Last logged events can be queried here. /MANAGEMENT/LOG node contains five properties (Warning, Error, Debug, Fatal and Notice), which shows the number of the occurrence of the given event type. The log can be emptied by the calling the clearLog method.

The node has five subnodes (NOTICE, WARNING, ERROR, FATAL, DEBUG) which contain the log entries as a property describing the logged event with details.

Page 68

Page 68 / 90 Section 8. Programmer’s reference

8.3.4. /EDID

The node and its subnodes represent all information about EDID management. The node contains basic methods in connection with EDID emulation such as Copy, Delete or Emulate EDID. Subnodes refer to the type of the EDID as follows:

F: Factory EDIDs, U: User EDID, D: Dynamic EDID (The EDID of the monitor last attached to the receiver), E: Emulated EDID (List of assigned video ports).

The node structure of Factory, User and Dynamic EDIDs contain the available EDIDs as subnodes. The structure of these EDID subnodes is the same:

Header: Valid/Invalid (based on EDID header) Data: EDID data – in HEX format IsValid: True/False – (based on EDID data)

For detailed information about EDID memory see section 4.3 on page 23.

8.3.5. /MEDIA

MEDIA node contains the available layers on installed modules, such as VIDEO, AUDIO, UART or IR module. Port and Crosspoint settings are structured in subnodes with methods and properties in the nodes of the layers.

8.3.6. /SYS

The node has two subnodes: LOG and CORE.

/SYS/LOG

Last log events collected from last booting. The structure is the same as for /MANAGEMENT/LOG.

/SYS/CORE

The node contains properties of MODEX frame; nevertheless its subnodes contain the installed modules (B, C, D and E). Signal parameters are listed in the subnodes.
