4: Setup and Conguration • 21
©2014 Axia Audio - Rev.1.3.8
If the desire is to only mute the speaker and not trig-
ger the Busy indication, then wiring to pin 1 as opposed 
to pin 2 would accomplish this.
If  using  an  Axia  console,  the  Control  Room  (CR) 
monitor logic has active logic when the monitors are 
muted. This logic can be tied into the intercom station if 
the main GPIO port is congured to the same LW Chan-
nel logic as dened in the show prole of the Axia con-
sole. Figure 4-12 shows the busy signal is active when 
the monitors are muted.

Indicators
Intercom stations provide indicators on the Main 
GPIO port which can be routed to a hardware GPIO port 
for triggering of external devices. Pathnder can be used 
to monitor the Main GPIO  port  of these  state  changes 
and events can be trigger without the use of hardware 
GPIO ports.
The indicators, also referred to as lamps, are placed 
as GPI logic in the Main GPIO port so that GPIO routing 
will resolve as a GPO on hardware ports. Pathnder is 
able to monitor both GPI and GPO state changes.
PIN FUNCTION
GPI Pin1 Listening Lamp
GPI Pin2  
GPI Pin3 Ring Lamp
GPI Pin4 Mic Mute Lamp
GPI Pin5 Talking Lamp
Listening  Lamp  (GPI  Pin  1)  is  engaged  any  time 
the station is listening to a source. This can either be in 
cases where the station is monitoring a source or when 
another station is talking to the station, as this is also a 
Listen state.
Ring Lamp (GPI Pin 3) is engaged when a lower trig-
gered station calls. When the call is accepted, the ring 
lamp will release.
Mic  Mute  Lamp  (GPI  pin  4)  is  engaged  when  the 
Mic mute button on the front panel is pressed, engaging 
the  Mic mute  state.  Pressing  the  button  again  releases 
the Lamp and the mute state.
Talk Lamp (GPI pin 5) is engaged when the station 
is talking to another station or also when another 
station is listening.
Intercom Station Web Pages
The following section covers the HTML user 
interfaces available. Some of the information 
may be a repeat of items mentioned earlier. 
Home Page
Figure 4-12
The home page provides links to other conguration 
pages as well as provide software version, uptime, and 
internal temperature. The left hand side of the page is 
consistent with other pages as a menu with all the need-
ed links too. When accessing the device for the rst time, 
an authentication window comes up where the default 
username is user and there is no password. The home 
page will be  presented  after entering in the username/
password.
