DVI

Connect  the  EDID  Manager 

V4  and  the  sink  device  (e.g. 

projector) using a DVI cable.

USB

Optionally  connect  a  controller 

device  (e.g.  laptop)  to  the  USB 

port of the device.

Power

Firstly  connect  the  power 

adaptor to the DC input on the 

device, then to the AC power 

socket.

 Powering on the devices is recommended to 

do as the final step during the installation.

Important safety instructions

Please read and keep the information in the attached safety instructions supplied with the 

product before you start using the device.

Introduction

Thank You for choosing Lightware EDID MANAGER V4, our HDCP compatible HDMI/DVI 

EDID Emulator and cable extender with USB control. The device can store 79 EDIDs. It 

emulates and keeps a fixed EDID for the source. Thanks to our Advanced EDID Management, 

the device can trick the source (PC computer, laptop, etc.) by emulating any DVI/HDMI display 

(LCD monitor, projector) for continuous video output - even if the AV system is disconnected or 

powered down. With EDID emulation, the user can set up any DVI or HDMI output resolution, 

regardless of the used projector or monitor. This ensures that the overall system resolution can 

be controlled. There are 49 factory and 29 user programmable presets available, and the last 

attached display device’s EDID is also stored separately on address 00#, to be able to clone 

it to the input (clone mode).

DVI Connectors

DVI Input

The input has a built-in signal detection circuit with a LED indicator. The Signal Present LED 

lights green, if the INPUT connector senses an active DVI/HDMI signal.

DVI Output

Monitor hotplug is detected on the output port (Monitor Hotplug LED lights green). After a 

hotplug event, the EDID Manager V4 tries to read the EDID of the connected device. No output 

reclocking is provided. If a long DVI cable is connected then equalization and reclocking may 

be necessary at the receiver end of the cable.

Fiber Cable Powering

As a special feature, the device is able to supply 500 mA current on DDC +5V output (pin 14 on 

output connector) to power fiber optical DVI transmitters. Standard DVI outputs or VGA cards 

supply only 55 mA current on +5V output, thus unable to power directly a fiber optical cable.

Appliable Cable Length

Maximum 60 meters 22AWG DVI cable is recommended for 1080p (Full HD) resolution on 

the input.

Features

 

ƒ

Advanced EDID Management

 – The user can emulate any EDID on the device’s input 

by using the 49 factory or 29 user presets. Any attached monitor’s EDID can be read out, 

edited and stored as user presets by the Lightware Device Controller Software.

 

ƒ

HDCP Management

 – HDCP communication between source and display devices can 

be permitted or prohibited by the unit. Lightware is a legal HDCP adopter.

 

ƒ

60 meter input cable compensation

 – Using 22AWG high quality DVI cable, the input 

is automatically compensated for up to 60 meter cable length, which extends installation 

possibilities  even  on  highest  HDTV  or  computer  resolutions.  In  case  of  lower  pixel 

resolutions, this length can be even higher.

 

ƒ

Top panel control

 – EDID address selection with two decimal rotary switches, Learn 

EDID and Burn EDID buttons are available for Advanced EDID Management.

 

ƒ

USB control

 – The EDID Manager V4 is controllable via the Lightware Device Controller 

software where Advanced EDID Management is available. Firmware upgrade can also 

be performed over this interface.

 

ƒ

Supports all HDTV resolutions

 – Supports HDCP encrypted and unencrypted HDTV 

signals up to 225 MHz pixel clock frequency regardless of the resolution being passed 

through. (720p, 1080i and 1080p etc.)

 

ƒ

Fiber cable support

  –  Self-powered  DVI  fiber  cables  using  +5V  from  DVI  sources 

(VGA cards, etc.) usually consumes more than 50 mA (maximum suggested by DVI 1.0 

standard). Lightware devices s5V 500 mA constant current output on the DVI 

outputs to power long distance fiber optical cables.
