Nextiva S4200 Series User Guide
With SConfigurator, you activate the alarm process by checking the Forward I/O box in the
Connection Creator window.
Audio
Two transmission modes for audio data are available, provided audio is supported
everywhere in your system:
„
Full duplex—Data is transferred in both directions simultaneously. The I/Os are
available for alarms.
„
PTT—The push-to-talk mode is a half-duplex mode that allows you to control audio
communication between two devices by using a button to transmit.
When creating a point-to-point connection between an S4200 transmitter and an S1970e-R
receiver in SConfigurator, you set the transmission mode in the Connection Creator window.
To activate the audio transmission channel, you must trigger an activation switch (for
example, a button) that is based on the shorting of the alarm input 2 and alarm ground
pins. If the PTT switches of both the transmitter and receiver are activated at the same
time, the receiver will have precedence: Audio will be transferred from the receiver to the
transmitter.
Here is a typical PTT application in a point-to-point context:
The S4200 device supports the line-in input type. With SConfigurator, ensure that the input
type in the Audio tab reflects this value.
Regardless of the transmission mode, the connections for the audio equipment are:
„
You plug the audio input signal of the device to the Line-out connector on a
pre-amplifier. Then you plug a microphone on the pre-amplifier.
„
You plug the audio output signal of the device to the Line-in connector on an amplifier.
Then you plug a speaker on the amplifier.
