Icom Station to other devices
(External Sources)
In some applications the desire is to not interact with
another station, but a device that is not an intercom sta-
tion or maybe another type of communication device.
External Source option provides some options to accom-
plish these tasks.
Icom Station monitor (Listen)
of external source
Intercom stations can act in the role of a monitoring
station. The station can be congured to communicate
with other stations and monitor particular sources. For
example a news room would want to be able to talk to
various studios, but also monitor the TV audio.
Go to the external sources page of the intercom sta-
tion. Provide a label descriptive of the source. Enter in
the Livewire channel number of the source, for example
a source of an analog xNode.
Figure A-5
If not familiar with creating sources from an Axia xNode,
please refer to documentation for that product.
Once the external sources are dened, edit the Key
Assignments. The drop down for each key should pro-
vide the External sources as options.

Icom Station to PTT Radio
Intercom stations support logic triggering when a
channel is in Talk mode and Listen mode. Congure the
external source with a Livewire channel, dene a GPIO
port out of the 8 virtual ports, and dene a pin for Talk
and a pin for Listen.
Fig u r e A-7
Setting up an xNode’s GPIO port with the intercom sta-
tion is by conguring a GPIO route between two ports as
seen in the following gure.
Figure A-8
The Talk or Listen mode occurring on the Intercom
Station will cause the corresponding GPO pin on the
xNode to go low. Likewise, if the GPI pin correspond-
ing to either mode is triggered on the xNode, then the
Intercom Station will engage into that mode. So in the
case where Pin 1 is assigned as Talk, the PTT Radio
