RX (receiver) unit conguration
In an ALIF dual system, it is the RX unit (receiver) that determines where and how data
signals are sent (and received) by the TX unit. Although numerous topologies (one-
to-one, one-to-many, many-to-one, etc.) are made possible by the ALIF system, they
are all dependent on two underlying modes of operation: either Unicast or Multicast
transmission. Where multicast transmission is not invoked for video and/or audio data,
operation will be automatically served by unicast network transmission technologies.
The RX unit setup (using the System Conguration page of its browser-based
conguration utility) is concerned with four main factors: Its own IP address(es), the data
streams to enable/disable, the IP address(es) of the TX unit and multicast transmission
details. Other pages, such as USB Settings, System Messages, Firmware Upgrades and
Reboot are generally not used or altered during the majority of installations. For further
details about RX unit conguration pages, please see the AdderLink Innity dual guide.
Conguring the RX unit
1 Display the RX unit System Conguration page.
2 In the System Conguration section, ensure that the IP address and Netmask settings
for the System and Teaming ports for this RX unit are correct. The default settings
of 169.254.1.32 and 169.254.1.42 for the two ports respectively are their zero cong
addresses - these are usually changed to some other address suitable for your installation.
Indeed, the zero cong address for the System port MUST be changed before the
Teaming port can be used. Enter the new values and click the Update Now button.
The System IP Address that is set here will be sent to the TX unit as the destination
for transmitted data (when operating in unicast mode). The Gateway entry is only
necessary when the TX unit is located on a separate network to the RX 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 TX unit conguration; 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, click the Update Now button.
4 If necessary, alter the Audio Input Type to match your audio input. The line option is for
a stereo line input, mic and mic boost are for mono microphones, the latter beneting
from a +20dB gain boost.
