A rough guide to configuring TX and RX units
TX (transmitter) unit configuration
In the ALIF 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 TX unit are correct. The default settings
are 169.254.1.33 and 255.255.0.0 respectively. Where changes are necessary, enter the new
values and click the Update Now button. You will need to declare the System IP Address
that is set here to the
RX unit(s)
linked to the TX unit.
3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable
Serial, if used) are enabled (ticked) or disabled (unticked) 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 one of these options 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 system is connected to a Gigabit Ethernet network 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. 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
TX Video Configuration
for individual explanations of the controls.
