A rough guide to configuring TX and RX units
TX (transmitter) unit configuration
In an ALIF dual system, the majority of configuration settings are dictated by the
RX
units
. Therefore, the local TX unit setup (using its browser-based configuration 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 configuration page options.
Setting the TX address and output signal details
1 Display the TX unit
System Configuration
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 config addresses - these are usually changed to some other
address suitable for your installation. Indeed, the zero config 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 configuration 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 sufficient available
bandwidth, there should be no need to alter the default settings on this page.
1 Display the TX unit
System Configuration
page and then change to the Video
Configuration 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 color quality is important, then leave
Colour Depth
at 24 bits and adjust other
controls,
• 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 Configuration
for individual explanations of the controls.
