Version 1.2  July 2010

Each virtual GPIO port has a Name box where you 

may enter any name to describe the port.  It also has a 
Channel  box  where  you  will  enter  the  IP Address  and 
port  of  a  GPIO  node.  For  example,  you  would  enter 

192.168.0.120/5 in the Channel box if you anted to as-

sociate a Virtual GPIO port with port 5 of a GPIO node 

(or Element) with an IP address of 192.168.0.120.

Please refer to 

Appendix B:  Connecting GPIO

 for 

more details and a real world example. 

Intercom Livewire Sources

IP-Intercom sources use an automatic source adver-

tising scheme so no setup or external software is required. 

You may also wish to interface your IP-Intercom sys-

tem  to  other  non-Livewire  equipment. You  can  accom-
plish  this  easily  by  using Axia  audio  nodes  and  GPIO 
nodes  and  configuring  those  sources  in  this  section. 

These  external  sources  might  be  talkback    from  exist-

ing analog consoles or interconnections to  wireless in-
tercom systems. External sources could also be sources 
that you might occasionally wish to monitor such as TV 
audio.

Label

The label may be customized to help you easily iden-

tify these external sources. Keep your label short so it 

will fit in the 10-character OLED display. 

Livewire Channel

The  Livewire  Channel  is  automatically  populated 

when you select a Source by using the pop-up control 

that is located to the right of the Livewire Channel box. 

Clicking on this selector button will open a new window 

that will list all Livewire sources in your entire network. 

Simply select the one that you want to make it available 

to your intercom station. 

Once a label has been specified and a Livewire chan-

nel  selected,  clicking 

Apply

  will  add  a  new  source  to 

the station. 

GPIO Port

This source GPIO Port refers to the port number as 

listed on the 

GPIO Configuration

 area of the intercom 

station  configuration.  This  drop-down  control  allows 

you to associate these channels with AUX GPIO ports 1 

through 8. These AUX ports are defined on the Livewire 

GPIO configuration page that was discussed above.

Talk

 and 

Listen

 pins are selected by the associated 

drop-down selector. Pins 1 through 5 are available.

Each external source GPIO port is assigned separate 

Talk and Listen pins that will allow you to interface these 

sources to the real world. Since each port has five pins, 

you can double-up two sources on a single GPIO port (2 

talk pins and 2 listen pins. 

Talk Pin

A contact closure to this pin will replicate pressing 

the front panel Talk key associated with this source. 

Listen Pin

A contact closure to this pin will replicate pressing 

the front panel Listen key associated with this source. 

It is very important to understand the logic of Talk 

and  Listen  as  they  apply  to  local  and  remote  users. A 
local  Element  user  will  press  Talk  when  he  wants  to 
talk. A remote user will place the Element’s IP-Intercom 
channel into Talk mode when he wants to Listen to the 
Element operator. This seems a bit strange but it is the 
same way a conversation takes place. At any given point 
in time, one user is talking while the other is listening. 

When  the  Element  channel  is  in  Talk  mode,  the  Ele-

ment’s Operator is talking and the remote user is listen-
ing to him. The same logic follows through to the Listen 
function. When the CR Operator must Listen when the 
remote user Talks - so in order for  this exchange to take 
place, the Element’s IP-Intercom station must be in Lis-
ten mode. Of course, since our communication path is 
full-duplex,  we  can Talk  and  Listen  simultaneously  so 
there is no limitation imposed.

NEW

Additional Livewire sources can be added to the list 

of external sources by entering the relevant information 
in this row and then clicking the 

Apply

 button.
