Chapter 2: Overview
2. Overview
2.1 Introduction
The HDMI over LAN Extender 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 64 displays in video wall applications and unlimited displays
in a multicast application using a standard IT Ethernet structure on a LAN system.
The HDMI over LAN Extender supports Full HD 1080p, is HDCP compliant, and is
Blu-ray ready. 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 Available Models
Three transmitter/receiver pairs are available, and they are ordered separately by part
number. Choose from:
• MediaCento IPX Multicast Transmitter (VX-HDMI-IP-MTX) and MediaCento IPX
Multicast Receiver (VX-HDMI-IP-MRX)
• MediaCento IPX Unicast Transmitter (VX-HDMI-IP-UTX) and MediaCento IPX
Unicast Receiver (VX-HDMI-IP-URX)
• MediaCento IPX Video Wall Transmitter (VX-HDMI-IP-VTX) and MediaCento IPX
Video Wall Receiver (VX-HDMI-IP-VRX)
2.3 Features
2.3.1 Multicast, Unicast, and Video Wall Transmitters and
Receivers
• Extends high definition video signal over LAN (dependent on network
performance).
• Choose from 16 selections on the DIP rotary switch for pairing.
• Provides automatic EDID configuration.
• Uses well-developed Ethernet technology and TCP/IP communication protocol.
• Transmitters and Receivers are HDCP-compliant and Blu-ray ready.

Chapter 2: Overview
• HDTV compatible; support 1080p, 1080i, 720p, 720i.
• Compatible with popular screen resolutions: XGA, SXGA, UXGA, WSXGA.
2.3.2 Multicast and Video Wall Transmitter and Receiver
Functions
• Each transmitter can be multicast to up to 250 displays in multicast applications.
• Use an IGMP network to prevent network flooding.
2.3.3 Video Wall Transmitter and Receiver Exclusive Functions
The Video Wall versions enable video and audio to be sent to 250 outputs via IP.
While it is possible to send the same video to all outputs, you can format the video
wall so that separate sections of the video can be sent to different outputs. Basic
settings allow for bezel compensation and different arrays of screens. Advaned set-
tings allow for video manipulation to specific outputs.

causing elevated noise levels. Use the proper cable and make sure the display device
can handle the resolution and refresh rate selected.
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.

2.6.5 EDID Copy
Copying the EDID will enable the receiver to send correct resolutions to your output.
Although the default EDID will work in most cases, some monitors will not work
with it.
NOTE: EDID copy is required for DVI monitors.
To copy the 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.
2.6.6 Reset Button
To reset the system, press the “Reset” button once. The system will start to reset
after a short press on the reset button.

NOTE: EDID copy is required for DVI monitors.
Installing the Transmitter and Receiver
1. Connect a video source (PC, Blu-ray, etc.) to the Transmitter/Sender Unit.
2. Connect the monitor to the Receiver Unit with an HDMI cable.
NOTE: IF the source has HDCP, the monitor must support HDCP.
3. Connect transmitter and receivers to the desired network with a Layer 2/3 IGMP
switch using CATx cables.
4. Set matching TX/RX to the same rotary position (see Section 4.1, Basic
Configuration).
5. Apply the proper power to all connecting devices.
6. Monitors connected to receiver units will show IP address before connecting.

Chapter 4: Configuration
4. Configuration
4.1 Basic Configuration
The rotary switch on each device decides the channel of the device when booting.
For a receiver or receivers to connect to a transmitter, they must be on the same
channel. Each transmitter should be on a separate switch setting and the receivers
should be on the same switch setting as the desired transmitter. After you change
the switch setting, you must reboot the device for the changes to take effect.
4.2 Advanced Configuration
Advanced configuration is not needed but is available.
You can access devices through the serial interface or Telnet for advanced
configuration of network settings.
A serial/Telnet client is needed.
To see the IP address of a receiver:
Connect a receiver to a monitor and power on. Device information, including the IP
address, will be in the lower right corner. Reset the receiver if needed. If the receiver
is set to DHCP IP mode, a network connection is required.

Chapter 5: Advanced Commands
5.1 Advanced IP Commands
Each device has three possible modes of establishing an IP address: autoip, dhcp,
and static.
1. AutoIP is the default mode and it will always automatically assign available IP
addresses in the private IP domain 169.254.xxx.xxx
NOTE: The MediaCento IPX uses the Avahi zeroconf protocol to find an available IP
in the 169.254.xxx.xxx range.
2. DHCP client gets an address from the local DHCP server.
CAUTION: Make sure a DHCP client is connected or problems will occur.
3. Static allows you to manually change the IP address and netmask of the device.
This requires further input before reboot.
To change the IP mode, type in:
astparam s ip_mode <mode>
astparam save
(where <mode> is autoip, dhcp, or static)
(saves changes)
reboot
(reboots the device)
If static is selected, the following commands are needed before reboot. Type in:
astparam s ipaddr xxx.xxx.xxx.xxx (enter IP address for x’s)
astparam s netmask xxx.xxx.xxx.xxx (enter netmast for x’s)
astparam save
reboot
(saves changes)

5.3 Serial Extension
Serial extension can be done from one transmitter to all receivers linked. Telnet serial
extension is also available as a replacement of serial. Serial extension information:
Default baud rate: 9600
Data bits: 8
(unless changed manually)
Parity: Even
Stop bits: 1
724-746-5500

Page 27
Chapter 5: Advanced Commands
Flow control: None
NOTE: This is a two-way communication. The transmitter will receive any data sent
from the serial devices connected to the receivers.
Figure 5-4. Options controlling local serial lines.

blackbox.com
Chapter 5: Advanced Commands
For both transmitter and receiver units, the added RJ-11 to DB9 serial cable needs to
be connected to the second serial port on the devices.
5.4 Telnet Extension
Telnet serial extension allows for serial output from a receiver through a Telnet
connection. This disables serial input coming from a transmitter but allows for 2-way
communication to specific devices.
NOTE: Telnet extension requires custom firmware. For details, contact Black Box
Technical Support at 724-746-5500 or [email protected].
To set up a Telnet extension:
1. Using a Telnet protocol, use Port 6752.
