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.

1.3. Features
5
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.

2.6.3. DVI inputs and outputs
29 pole DVI-I connectors, however internally connected pins vary by interface types. This
way, user can plug in any DVI connector, but keep in mind that analog signals (such as

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 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.
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 / 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.
