4.13 A rough guide to configuring TX and RX units
4.13.1 TX (transmitter) unit configuration
In an Agility 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 appropri-
ate. 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 Agility 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 percent-
age 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.
3 Click Update Now to apply each setting change.
