Dial Button (*)
The “Dial” phone button turns the station keypad into a touch-tone phone
keypad, allowing DTMF tones (Touch Tones) to be generated for telephone
dialing. To place a telephone call:
1. Push a talk selector assigned to a telephone interface.
2. After the dial tone is heard, push the “Dial” phone button on the keypad.
3. Enter the phone number using the keypad buttons. The station will
automatically exit dial-tone mode after 5 seconds of keypad inactivity.
4. While the call is in progress, it is possible to enter dial-phone mode and send
DTMF tones to the destination.
This function can be inhibited from the configuration program.
SA (Studio/Stage Announce) Button (#)
This button functions only if the station is equipped with the OPT-100
Auxiliary Audio Input/Output option. Pressing and holding the “SA” button
sends the microphone output to the studio announce output on the Auxiliary
Audio I/O connector. All other talk paths from the station to the matrix frame
are turned off.
REAR-PANEL CONNECTORS
This section describes only those rear-panel functions directly affecting normal
station operation. These include the functions available through the
“Miscellaneous” connector and those added by the use of the “OPT-100
Auxiliary Audio” connector. The actual functions these inputs and outputs
perform depend on the installation of the individual station. This section only
describes the general use of these functions.
Miscellaneous Connector
The Miscellaneous connector includes the following functions:
• Logic input #1
• Logic input #2
• Programmable relay
• Mute relay
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 Option” on page 1-15).
