RX (receiver) unit configuration
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 Configuration page of its browser-based
configuration 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 configuration pages, please see the AdderLink Infinity dual guide.
Configuring the RX unit
1 Display the RX unit System Configuration page.
2 In the System Configuration 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 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. 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 configuration; 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 benefiting
from a +20dB gain boost.
