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 quality 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 MUST 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 extender units operate as described in Table 2-3.

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.

4.2.1 Accessing through Serial

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

Figure 4-1. PuTTY configuration screen using serial.

1. 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 port to 24.

Chapter 4: Configuration

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.

1. DHCP client gets an address from the local DHCP server.

CAUTION: Make sure a DHCP client is connected or problems will occur.

1. 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 (where is autoip, dhcp, or static)

astparam save (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 (saves changes)

reboot
