2: Configuring and Installing the Device
12 Verint Video Solutions
Since the S1900e devices are mostly used with a video management software, you will
perform most configuration and activation steps within it. Otherwise, in a point-to-point
context, use SConfigurator for setup.
Audio
If you purchased the audio option, you can use the two 3.5 mm jacks on the device.
Appendix E on page 51 presents the jack pinouts.
To activate audio between a transmitter and a receiver, both devices must support audio.
Data Transmission
Two transmission modes for audio data are available:
„
Full duplex—Data is transferred in both directions simultaneously.
„
PTT—The push-to-talk mode allows you to control audio communication between two
devices.
When creating a point-to-point connection between a receiver and a transmitter in
SConfigurator, you set the transmission mode in the Connection Creator
window.
To activate the audio transmission channel for PTT on the S1900e transmitter, you must
trigger an activation switch (for example, a button) that is based on the shorting of the
ground and input terminals.
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:
