A rough guide to conguring TX and RX units

TX (transmitter) unit conguration

In an ALIF dual system, the majority of conguration settings are dictated by the RX

units. Therefore, the local TX unit setup (using its browser-based conguration utility) is

usually concerned only with three main factors: Its IP address details, the data streams

to enable/disable and video signal optimization. Other TX unit pages, such as USB

Settings, System Messages, Firmware Upgrades and Reboot are generally not used or

altered during the majority of installations and are discussed elsewhere in this guide. See

Appendix A for explanations of all TX conguration page options.

Setting the TX address and output signal details

1 Display the TX unit System Conguration page.

2 Ensure that the IP address and netmask for the System port and the Teaming port (if

used) are correct. The default settings of 169.254.1.33 and 169.254.1.43 for the two ports

respectively are their zero cong addresses - these are usually changed to some other

address suitable for your installation. Indeed, the zero cong address for the System port

MUST be changed before the Teaming port can be used for network connections.

3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable

Serial, if used) are enabled as appropriate. There are similar options within the RX

unit conguration and it is important that the settings in both units are the same. If an

option is ticked in one unit but unticked in the other, then that data stream will remain

disabled. If you make a change, remember to click the Update Now button.

Optimizing the TX video signal

Note: Where the ALIF dual system is linked via two Gigabit links with sufcient available

bandwidth, there should be no need to alter the default settings on this page.

1 Display the TX unit System Conguration page and then change to the Video

Conguration page.

2 Make changes to the controls as necessary for each video port. There is no single

combination of adjustments that will suit all installations, but generally:

• If moving video images are being shown frequently, then leave Frame Skipping at a

low percentage and instead reduce the Peak Bandwidth Limiter and Colour Depth.

• Where screens are quite static, try increasing the Background Refresh interval and/or

increasing the Frame skipping percentage setting.

Make changes one at a time, in small steps, and view typical video images so that you

can attribute positive or negative results to the appropriate control.

See Video Conguration for individual explanations of the controls.
