source assigned to a channel, the channel’s Talk button
is pressed, the xNode’s GPIO port pin 1 will go low.

Wiring up the GPIO node to engage the radio and
having audio routed to the radio will allow the Axia In-
tercom station to key the radio and talk.
If the radio provides a carrier operated switch or
similar, this can be wired to the xNode’s GPIO port to
trigger the Listen mode of the Intercom Station.

GPI on pin 12 (known as the second pin of 5 GPIs)
would trigger a Listen mode if the Listen pin was set to 2.
Icom Station call to codec (IFB routing)
In some cases you may have multiple Intercom
Stations that need the ability to talk to a single exter-
nal source. The IFB Destination option assists with this
issue as it allows an Intercom Station to make a route
change to a destination when a Talk session is engaged.
The codec needs to feed cues from a producer, the pro-
ducer has an Intercom Station with a channel assigned to
the external source of the codec.
The IFB Destination eld is lled in with the IP
address of the Livewire enabled codec or a Livewire
I/O device. After the IP address should be the port
number, for example if an analog xNode is feeding
the stereo codec through the 4th port, the eld will be
lled as 192.168.100.98/4. In the case of a Zip/ONE,
there is a single stereo Livewire port so the eld is
192.168.100.101/1.
This will create a route change to the destination
when the Talk mode is engaged. Note, this is a stereo (2
channel) route change.
Icom Station call to Codec/Headphone
(console backfeed insert)
Intercom Stations have an option to tap into back-
feeds that are created by some Axia consoles. With Ele-
ment version 2.6-series, a new source type known as a
Flex Source supports a Talk insertion option. The envi-
ronment is the Element is used in a control room to a talk
studio. Behind the console operator are producers who
need to give cues to the hosts that are in the talk studio.
The producers are each provided an Intercom Station.
Dene an external source for each host position and
select the TB check box. The channel number is the same
number used to dene the source within the Element.
Within the Element’s Flex source prole, dene the
host positions and enable the “Feed to Source” and en-
able the “Talk Insertion”. When the source is loaded to a
console fader, pressing the Talk button on the Intercom
Station’s channel assigned to the External source, the
audio from the Intercom will be inserted into return feed
for the host headphones.
