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
