Chapter 2: Overview
2. Overview
2.1 Introduction
The MediaCento IPX with PoE is a perfect solution for audio and video signal
extension via an existing Local Area Network (LAN) system. With multicast
technology, one local unit can drive multiple remote units with no extra network
load. There are 16 selectable channels that can be used to transmit to multiple
receivers. In a network that supports IGMP (Layer 2 or Layer 3 switches), each
channel can connect to unlimited displays in video wall applications and unlimited
displays in a multicast application using a standard IT Ethernet structure on a LAN
system.
The MediaCento IPX with PoE supports Full HD 1080p, is HDCP compliant, is Blu-ray
ready, and supports Power over Ethernet (PoE). It can handle applications that
require greater distance, high speed transmission, real-time high video resolution,
security, and noise immunity. It is ideal for situations that need live presentation,
such as public broadcasting, education centers, boardrooms, etc.
2.2 Features
• Extend high definition video signal over LAN (dependent on network
performance).
• Power over Ethernet:
- Fully support IEEE Std. 802.3af-2003
- Input Voltage Range 36V to 57V
• Choose from 16 selections on the DIP rotary switch for pairing.
• Provide automatic EDID configuration.
• Use well-developed Ethernet technology and TCP/IP communication protocol.
• Transmitters and Receivers are HDCP-compliant and Blu-ray ready.
• HDTV compatible; support 1080p, 1080i, 720p, 720i.
• Compatible with popular screen resolutions: XGA, SXGA, UXGA, WSXGA.
• Each transmitter can be multicast to up to an unlimited number of displays in
video wall applications or unlimited displays in multicast applications.
• Use an IGMP network to prevent network flooding.

Chapter 2: Overview
2.5.3 Indicators
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.
NOTE: The system will disable the video output signal when it detects non-HDCP-
compliant display(s) trying to play on the HDCP video source. All the
connected output displays MUST be HDCP compliant when the video source
is HDCP compliant.
2.5.4 Function Buttons (F1 and F2) and Reset Button
The Function buttons (F1 and F2) on the extender units operate as described
in Table 2-3.
Table 2-3. Function buttons.
Button Action Description
F2 Press for 1 second. Toggle between graphics
and video mode.
F2
1. Press and hold the F2 button.
2. Apply power to the receiver
unit.
3. Release right after the
Network Status LED starts
blinking.

2.5.5 EDID Copy (on Receiver Unit only)
Copying the EDID will enable the source to send correct resolutions to your display.
Although the default EDID will work in most cases, some monitors will not work
with it.
NOTE: EDID copy is recommended for use with DVI monitors.
To copy EDID:
1. To copy EDID from a specific receiver to a specific transmitter, both receiver and
transmitter must be configured to the same channel.
2. Hold down the function button on the receiver and plug in the power.
3. Continue to hold down the function button until the network LED starts blinking.
EDID is now copied to the receiver.

Chapter 3: Installation
3. Installation
WARNINGS:
Make sure 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.
Allow adequate space around the unit for air circulation.
System Requirements for PoE
1. Make sure that a PSE device supports PoE function.
2. Make sure that a PSE device can provide sufficient power on the Ethernet cable.
3. We recommend that you use STP and FTP cabling.
3.1 Installation Steps
NOTE: The extenders are configured as multicast units by default. To use the
extenders in a plug-and-play unicast configuration, you must change the
default configuration. See Chapter 4, Configuration, for details.
1. Connect the video source to the transmitter unit.
2. Connect the monitor to the receiver unit.
3. Use CAT5 cables to connect transmitter/receiver to LAN hub.
4. Set an identical ID number on the rotary DIP switch for both transmitter and
receiver.
5. Apply the power to all connected devices (if you are not using a PoE switch).
NOTES:
A. We recommend that you use a Gigabit switch for optimum transmission quality.
B. If users cannot see the screen display on their computer connection, see Section
7.1 of this manual.
