Nextiva S1100w User Guide
The numbering of the pins on the DB-9 connector is:
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 47.
The S1100w supports two inputs and one output. Each signal has a dedicated purpose:
Input 1—Either transparent alarm links 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/PTLThe push-to-talk/push-to-listen mode allows you to control audio
communication between two devices.
When creating a point-to-point connection between an S1100w transmitter and an S1600e
receiver in SConfigurator, you set the transmission mode in the Connection Creator window.
The S1100w transmitters can do PTT only; the PTL portion is performed on S1600e
receivers in point-to-point configurations. 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 both the transmitter’s and receivers
PTT switches are activated at the same time, the receiver will have precedence: Audio will
be transferred from the S1600e receiver to the S1100w transmitter.
