Chapter 2: Overview

2. Overview

2.1 Introduction

The MediaCento IPX with PoE is a per fect solution for audio and video signal
extension via an existing Local Area Network (LAN) system. With multicast
technolo gy, one local unit can drive multiple remote unit s with no extra net work
load. There are 16 selec table channels that can be used to transmit to multiple
receiver s. In a net work 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 I T Ethernet structure on a LA N
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,
securit y, and noise immunity. It is ideal for situations that need live presentation,
such as public broadcasting, education centers, boardrooms, etc.

Chapter 2: Overview

2.6.3 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.

The qualit y of the output signal will depend largely upon the quality of the video
source, cable, and display device used. Low- quality cables degrade output signals,
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 MUS T be HDCP compliant when the video source
is HDCP compliant.

2.6.4 Function Buttons (F1 and F2)

The Function buttons (F1 and F2) on the ex tender units operate as described
in Table 2-3.

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 c ases, 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 net work LED start s blinking.
EDID is now copied to the receiver.

Resets the box to factory
defaults.

Chapter 3: Installation

3. Installation

WARN IN G S:

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.

NOTE: EDID copy is required for DVI monitors.

System Requirements for PoE

1. Ensure that a PSE device supports PoE function.

2. Ensure that a PSE device can provide sufficient power on the Ethernet cable.

3. STP and F TP cabling are recommended.

Installing the Transmitter and Receiver

1. Connect a video source ( PC, Blu-ray, etc.) to the Transmit ter/ Sender Unit.

2. Connect the monitor to the Receiver Unit with an H DMI cable.

NOTE: IF the source has HD CP, the monitor must support HDCP.

3. Connec t transmit ter 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 connec ted to receiver units will show IP address before connecting.

NOTE: Figure 3-1 shows this installation.

Chapter 4: Configuration

4. Configuration

4.1 Basic Configuration

The rotar y 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 transmit ter should be on a separate switch setting and the receivers
should be on the same switch set ting 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 net work connection is required.

Page 22

724-746-5500 | blackbox.com

Chapter 4: Configuration

4.2.1 Accessing through Serial

1. Using the client, select “serial” and enter “115200” for the speed (baud rate) .

Figure 4-1. PuT TY configuration screen using serial.

2. No username or password is required. Just press enter.

4.2.2 Accessing through Telnet

1. Using the client, enter in the IP address of the device.

2. Change the por t to 24.

Chapter 5: Advanced Commands

5. Advanced Commands

These are advanced configurations and require knowledge of IP networking
protocols and multicasting. Do not attempt to run any commands, modif y files, or
change any other settings apart from the specific configurations noted here.

All commands are case-sensitive.

To list names and I P information of all connected MediaCento IPX devices, type in :

node_list

Figure 5-1. Names and IP information list.

To view all current configured parameters, type in:

astparam dump

724-746-5500 | blackbox.com Page 25

Chapter 5: Advanced Commands

Figure 5-2. Current configured parameters list.

To reset to factory default, setting the IP mode to autoip and removing any
overrides, type in:

reset_to_default.sh

To change the baud rate of the serial extension interface, type in:

stty X – F /dev/ttyS0

(replace X with desired baud rate )

To disable /enable the link for a specific device, type in:

ast_send_event -1 e_stop_link

ast_send_event -1 e_reconnect

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.x xx.xxx

NOTE: The MediaCento IPX uses the Avahi zeroconf protocol to find an available IP

in the 169.254.x xx.xxx range.

Page 26

724-746-5500 | blackbox.com

Chapter 5: Advanced Commands

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_mod e <mode> (where < mode> is autoip, dhcp, or static)

astparam save (saves changes)

reboot (reboots the device)

If static is selec ted, the following commands are needed before reboot. Type in:

astparam s ipaddr xxx.x xx.xxx.xx x (enter IP address for x’s)

astparam s netmask xxx.xxx.xxx.xxx (enter netmast for x’s)

astparam save (saves changes)

reboot

For both transmitter and receiver units, the added R J-11 to DB9 serial cable needs to
be connec ted to the second serial port on the devices.

connection. This disables serial input coming from a transmitter but allows for 2-way
communication to specific devices.

NOTE: Telnet e xtension requires custom firmware. For details, contact Black Box
