AppendIX c - multIrAck on unIdIrectIonAl networks
Under most circumstances, MultiRack requires an IP path in both directions for successful connections, even when
audio is being sent only one-way. For networks that provide data only in one direction, it is possible to use Standard
RTP mode to establish and maintain these links. This section describes how to set that up.
The codec has several compatibility modes under the Standard RTP channel mode. The units default to a mode that
is compatible with the Luci Live PC-based encoder. This must be changed on both codecs.
• On the MultiRack, click the System Settings tab and select Show Advanced Options.
• Find Standard RTP Settings and choose to edit the RTP Compatibility Mode.
• Change this setting to Standard and click Apply.
stAndArd rtp settIngs
The following setting instructions apply to both codecs in the link (encoder and decoder):
decode sIde settIngs only
Under Advanced Standard RTP Settings, find the Return Channel Enable entry. Disable the return channel and
click Apply (or Save on ACCESS Portable). This will make sure that no channel will be set up in the direction to the
encoder.
encode sIde settIngs only
Connections of this type must be established from the encoding side of the link. A new Profile must be built that
uses the Standard RTP channel mode under the Profile Editor. Choose an outgoing encoder along with any other
special attributes in the profile editor. Name the Profile something descriptive like "Simplex".
Next, create an outgoing remote entry in the address book. Apply the new profile to that entry. Any connection
made with that entry will connect in a unidirectional fashion.
Full-tIme or trIggered connectIons
A remote entry using a unidirectional profile can still utilize the tools required for automatic connection.
To set up a connection to be "always active" (i.e., reconnect in the case of power outage or network failure), choose
that connection on the System Settings tab as the Always Connect To location.
To trigger the connection when an external contact is closed, choose the connection under one of the Contact
Closure settings on the System Settings tab.
