Configuring the I/Os
To program alarms (or events) or use the audio features of the S1100w device, you need
the CAB8P cable assembly. For detailed pinout information, see page 55.
The S1100w supports two inputs and one output. Each signal has a dedicated purpose:
„
Input 1—Either a transparent alarm link in a point-to-point configuration or with a video
management software, or PTL (push-to-listen) audio transmission mode.
„
Input 2—Push-to-talk (PTT) audio transmission mode.
„
Output—Relay for the input 1 signal in point-to-point alarm mode.
You cannot program PTT/PTL audio and alarms at the same time, since input 1 is used in
both contexts.
Since the S1100w transmitters are mostly used with a video management software, you
will perform most configuration and activation steps in it. Otherwise, in a point-to-point
connection, you use SConfigurator for setup.
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 allows you to control audio communication between two
devices.
When creating a point-to-point connection between an S1100w transmitter and an S1970e
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
signals. 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 S1970e receiver
to the S1100w transmitter.
