Overview
The HDMI over Giga LAN Extender is a perfect solution for audio and video signal
extension via existing LAN (Local Area Network) system. It’s Plug-and-Play basis in
uni-cast application, neither GUI control nor RS232 setup is required. However, you
need to set an identical ID number (Rotary DIP Switch) for each Sender and Receiver
unit.
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 65536 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.

------------------------ Part 1: Uni-Cast Configuration
I. Installation
1. Device Connection
WARNING!
●Ensure that all devices are powered off before connecting to the Unit.
●Make sure all devices you will connect are properly grounded.
●Place cables away from fluorescent lights, air conditioners, and machines
that are likely to generate electrical noise.
●Please allow adequate space around the unit for air circulation.
1. Connect the video source to the Sender Unit.
2. Connect the monitor to the Receiver Unit.
3. Use CAT5 cables (EIA / TIA 568B industry standard compliant) for connection
between Tx/Rx and LAN Hub.
4. Set an identical ID number on Rotary DIP Switch for both Units.
5. Apply the proper power to all connecting devices.
NOTE:
A). It is highly recommended using Giga Ethernet Hub for optimal transmission quality.
B). If users encounter no screen display in computer connection:
1. Make sure the device cables are correctly and firmly attached.
2. Set your display device’s (TV, monitor, etc.) input source as HDMI.
3. Check the PC BIOS configuration about the video output setting.
4. Connect your computer to the HDMI Display DIRECTLY to check if the video
signal gets through.
5. Set the Rotary DIP Switch to the correct position.
6. Inappropriate EDID data. Apply EDID Copy to your display (see EDID
Configuration section).
7. HDCP issue. 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 while the video source is
HDCP compliant.

III. Operation
The LEDs on the Extender Units show the real-time status indicating the linking and
communication between the 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:
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.
1. Setting
User needs to do the first thing setting Unicast mode in the browser because factory
default is Multicast Mode.
1.1 How to set Unicast for Sender
A). Domain Name
The first thing users need to do is setting the unit as Uni-cast mode via
browser because the factory default setting is Multi-cast mode. Identical ID
setting on the rotary DIP switch of both Sender and Receiver is essential.
Open web browser and insert the address. Please see the “Network
Configuration” section.
B).IP
Open web browser and insert Sender’s IP address. If you don’t know IP
address, you could find on the corner of Host Selection. Please see the
“Network Configuration” section.
C).Serial Command
1.2 How to set Unicast for Receiver
A).IP
Open web browser and insert Receiver’s IP address. If you don’t know IP
address, you could find on the corner of Host Selection. Please see the
“Network Configuration” section.
B).Serial Command
For more detail, please follow Network Configuration.

3. 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)
NOTE:
1. Using HDMI or DVI for all monitors; do not mix them up in one system.
2. It is suggested using monitors with identical brand and type.

4. Network Configuration
User may want to exchange casting mode between unicast and multicast, set up IP and
use EDID Copy function. There are two way to reach, browser and serial command.
2.1. To complete users' goal, configuration via browser is divided into two ways,
a. Typing Domain Name in the address bar
b. Typing IP in the address bar
Before starting take notice of differentiation between Domain Name and IP.
2.1.1. System configuration via Domain Name
aDomain Name is for Sender only.
b. It is suggested using “Safari” web browser or other web browsers like Google
Chrome, Firefox or IE…, etc. If you use other web browser which is not Safari you’ll
need to install “bonjour SDK”: Go to the website
http://developer.apple.com/opensource/ and look for “bonjour SDK download” for
installation.
c. The same pair of Sender and Receiver should have identical ID (Rotary DIP
Switch number)
d. Open web browser and insert the address: http://videolan-gateway0000.local
The four digits after the word “videolan-gateway” depends on the position of the Rotary
DIP Switch you’ve set. Please refer to the form below. For example, if the position is
set up as 7, then the address should be http://videolan-gateway1110.local
