Turn the EDID rotary switches to the desired position (between #62 – #98).
Press the LEARN button and keep it pressed for three seconds.
The OUTPUT LED turns dark for a second, then provides feedback:
- BLINKING (green): EDID learning is successful, the EDID is stored.
- BLINKING (red): EDID learning is failed.
The LED turns dark for a second, then shows the state(s) of the connected sink(s)

Further EDID options

The following functions are available when connecting to the device by LDC:

EDID learning or importing an EDID.
Exporting an EDID and saving it as a file.

Powering Options

The device can be powered by any of the following ways:

Using the supplied power adaptor (recommended).
Connect the device to a proper USB port by the supplied cable.
Connecting an HDMI source to the HDMI input port.

Make sure that the port is able to supply 5V 500 mA current

If the power adaptor is connected, it will supply the device independently from the HDMI/ USB ports. If the adaptor is disconnected from the DC input connector, the device tries to use a different power source (HDMI or USB) if it is enabled and connected. (If the adaptor is unplugged from the AC socket but the DC plug is still connected, the device will be switched off and cannot be changed to another power source. Unplug the DC cable from the device to be powered by USB or HDMI.)

The USB and HDMI powering modes can be enabled/disabled via the LDC software.

If you are not sure that your USB or HDMI port has enough power, disable the powering over USB and HDMI by Lightware Device Controller software. If the supplied power over USB or HDMI is not enough, the device will switch off. In the case of any strange behavior of the device, please disconnect the USB and HDMI cables and connect the 5V DC adaptor.

HDCP management

The HDCP setting of the HDMI input port can be enabled/disabled on the front panel as follows:

Turn the EDID rotary switches to ‘01’ position.
Press the LEARN button and keep it pressed for three seconds.
The lower three LEDs give displays if the HDCP state is changed:
- Output→Audio→Input LEDs are dark and light up sequentially: HDCP is enabled.
- Input→Audio→Output LEDs light and get dark sequentially: HDCP is disabled.

Restoring the factory default settings

The settings and parameters can be set to factory default as follows:

Set the rotary switches to ‘00’ position.
Press and keep pressing the LEARN button for three seconds. When the lower three LEDs blink, release the button. The following settings and parameters are restored:

HDCP (input port): enabled
HDCP (output port): auto
HDMI mode (output port) : auto
HDMI output port (audio signal): unmuted
Test pattern generator: off

Software control – Using Lightware Device Controller (LDC)

The device can be controlled from a computer using the Lightware Device Controller software. The application is available at www.lightware.com (Support / Downloads section), install it on a Windows PC or a MacOS and connect to the device.

Connecting by the USB port

Connect the supplied USB cable between the device and the computer and start the LDC.

The device is displayed under the USB devices section; select it, then press Connect.

Crosspoint menu

When LDC connects to the device, the Crosspoint menu is shown by default. The input and output port settings are available separately for the video and audio signals. Besides, the following tools are available:

Frame detector

The 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.

Test pattern generator

The output ports can send a special image towards the sink devices for testing purposes. The settings of the test pattern are available via LDC:

Mode

On: the test pattern is always sent to the output port.
Off: the test pattern generator is off.
No signal: the test pattern generator is switched on if video signal is not detected.

Clock source

480p / 576p / Original video signal: the clock frequency of the test pattern.

Pattern

Red / Green / Blue / Black / White / Ramp / Chess / Bar / Cycle. Cycle setting means all the patterns are changed sequentially approx. in every 2 seconds.

EDID management

Advanced EDID Management can be accessed by selecting the EDID menu. The software allows to create, modify, delete, import, or export EDIDs. Please note that the factory presets cannot be modified.

EDID emulation is available only by the EDID rotary switches on the device

**Backup and restore (Configuration cloning)

**

This simple method eliminates the need to repeatedly configure certain devices to have identical (non-factory) settings. If the devices are installed in the same type of system multiple times, then it is enough to set up only one device to fit the user’s needs and then copy those settings to the others, thus saving time and resources. Installing multiple devices with the same customized configuration settings can be done in a few easy steps:

Configure one device with all your desired settings with the LDC software.
Backup the full configuration file to your computer.
If needed, make some modifications to the configuration file using a text editor.
Connect to the other device that has to be configured and upload (restore) your configuration file.

Firmware update – Using Lightware Device Updater (LDU)

Preparation

The following are necessary to perform a firmware update:

Lightware Device Updater software – available on www.lightware.com,
Firmware package of the device (LFP file) – please contact support@lightware.com.
Power adaptor to supply the device

Performing the Update
