ICS-2003 INTERCOM STATION
2-5
feed (program audio) can be heard on the station’s speaker and headset; it cannot
be heard by other stations in the Matrix system.
To connect an external program feed to the station:
1. Connect the balanced audio pair to pins 1 and 9.
2. Connect a shield or ground connection if available to the connector’s pin 2
(see Figure 7 on page 1-4).
Logic Input #1 and #2
Each input can control one of several functions, determined through the
configuration program. Typically, these inputs are connected to an external foot
switch, a panel-mounted switch, or the logic output of another device.
The following functions are available:
• Mic On/Off—toggles the station’s microphone on and off.
• Mute Mic Output To Frame—turns off the audio from the station to the
frame. It does not turn off the Hot Mic output (described in “OPT-100
Auxiliary Audio I/O Option” on page 2-7). For an example of how to use this
option, see “External Program Feed Input” on page 2-4.
• Mic Off —momentarily turns off the station’s microphone.
• Answer Back Talk/Clear—the same functions as the station’s “Answer Back”
key. Holding down the switch activates a talk to a label in the answer-back
stack. To clear the label, quickly press and release the switch.
• Studio Announce—sends the output of the station’s selected microphone
(panel or headset) to the station’s Studio Announce (SA) audio output, and
activates the SA relay. The microphone output is not sent to the frame. The
SA output and relay are only present if the station has the OPT-100 Auxiliary
Audio I/O Option installed. (The SA options are described in “OPT-100
Auxiliary Audio I/O Option” on page 2-7).
• Speaker OFF—turns off the station speaker, disabling all audible output from
the station.
• PTT: Activate All Talk Keys (Push To Talk)—when enabled from the
configuration program and the logic input is active, the station behaves
normally. When this function (logic level) is deactivated, it disables activation
of all talk labels, implementing a push-to-talk function for the station. Any
controls (relays, etc.) assigned to the labels are activated or deactivated along
with their assigned labels. The LED indicators associated with the active labels
behave normally regardless of this input’s activity. This input controls
momentary and latched talks.
• Activate Talk Switch #1—equivalent to pressing the station’s first (leftmost)
talk selector; a momentary and latching activation.
• Activate Talk Switch #2—equivalent to pressing the station’s second talk
selector; a momentary and latching activation.
• Activate Listen Labels Button—equivalent to pressing the “Listens” button on
the keypad; all modes of the “Listens” button are supported.
