------------------------ Introduction
Overview
The HDMI over Giga LAN Extender is a perfect solution for audio and video signal
extension via existing LAN (Local Area Network) system. With multicast technology,
one local unit can drive multiple remote units with no extra network load. Via IGMP Giga
Hub, there are 16 channels selectable and up to 4 channels can be transmitted
simultaneously. Amazingly, each channel can be shown to an incredible 256 displays
using a standard IT Ethernet structure on a LAN system. For each source device a local
unit is required, and a remote unit is needed for each display device.
The HDMI over Giga LAN Extender is Full HD 1080p supported, HDCP compliant and
Blu-ray ready. Moreover, this has been common used in applications that require
greater distance, high speed transmission, real-time high video resolution, security, and
noise immunity. Based on Giga LAN structure, it supports super-high speed
transmission. It is ideal for situations that need live presentation, such as public
broadcasting, education center, boardrooms, etc.

------------------------ Operation
The LEDs on the Extender Units show the real-time status indicating the linking and
communication between the Transmitter/Sender Unit and the Receiver Unit. Users can
identify the current status through the LED indicators on the unit.
The quality of the output signal will depend largely upon the quality of video source,
cable and display device used. Low quality cables degrade output signal causing
elevated noise levels. Please use the proper cable and make sure the display device is
capable of handling the resolution and refresh rate selected.
NOTE:
1. The system will disable the video output signal when it detects non-HDCP compliant
display(s) on playing the HDCP video source. All the connected output displays
MUST be HDCP compliant, when the video source is HDCP compliant.
2. It is NOT suggested setting up your screen array as N (row) x 1 (column) when
horizontal resolution is greater than 1280 pixels.

------------------------ EDID Configuration
EDID (Extended Display Identification Data) is greatly important which contains
information about manufacturer name and serial number, product type, maximum
image size, color characteristics, factory pre-set timings, frequency range limits, etc. In
some cases display problems may occur due to incorrect EDID communication
between the display monitor and the unit or inappropriate EDID data programmed by
display manufactures. Therefore, by adopting “EDID COPY” function, it will allow the
system to copy EDID information from EDID compliant displays in order to assure
accurate display performance.
●EDID Copy (on Receiver Unit only)
Step 1. Power off the unit
Step 2. Press and hold the button F2
Step 3. Power on the unit
Step 4. Release the button after 12 sec. (the Network Status LED flashes yellow)
However, owing to a variety of monitor model types, EDID data may not be usable to all.
For example, if you use an HDMI-to-DVI converter to a REAL DVI monitor, the copied
EDID (DVI) data may NOT be applicable to HDMI monitors. On the other hand, if using
an HDMI-to-DVI converter to a DVI monitor (but in fact it’s an HDMI monitor with DVI
connector), the copied EDID (HDMI) data may be applicable to HDMI monitors.
