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:

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)

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:

6. Accessing the Web Interface  
The Web interface can be used to view information about the device, upload a  
firmware file to the device, and for video wall transformers configuration. The Web  
interface will not give network information or screen previews.  
6.1 Accessing the Transmitter without an IP Address  
You can access the transmitter directly with a serial connection, and find the IP  
address using the “node-list” command. See Chapter 5. To connect without an IP  
address or serial connection, access the Web interface.  
Bonjour® is needed to access the Web interface. Apple® products usually have this  
installed. If needed, you can download the free version from  
1. Run Bonjour.  
2. Configure the control PC’s network setting as 169.254.xxx.xxx IP domain with  
netmask 255.255.0.0. Default gateway and DNS can be left blank. For Windows®  
four digits after ast-gateway depend on the position of the Rotary Switch you’ve  
set. Please refer to Table 6-1. For example, if the position is set up as 7, then the
