Adding an Antenna
If you bought a high gain antenna, install it after the device is in place. The antennas
provided by Verint are designed to be mounted on a mast or pole of 2–3 inch (5–7.5 cm)
diameter.
To install an external antenna:
Warning: Even if you are using an external antenna, do not remove the integrated one;
otherwise the warranty becomes void.
1. Install the antenna above the S1100 device. If you bought your antenna from Verint,
use the supplied pole mount bracket.
2. Screw the SMA connector of the antenna cable to the S1100 antenna port and tighten it
with a 0.25 inch (0.6 cm) wrench.
Warning: Do not over-tighten to avoid damaging the connector. The recommended
torque is 8 lb-in. (100 N-cm). You could use a calibrated SMA torque wrench
(for instance, from the Pasternack company, available at
www.pasternack.com).
3. Apply two or three layers of electrical tape around all RF connections.
The antenna cable and connectors are weather-tight; however, vibration caused by the
wind will over time loosen the connectors and reduce the efficiency of the gaskets. The
electrical tape will prevent this situation.
4. Carefully align the antenna with that of the other device so that both have a clear RF
line of sight.
Configuring the I/Os
To program alarms or use the audio features of the device, you need the CAB8P cable
assembly. For detailed pinout information, see page 55.
The S1100 supports two inputs and one output. Each signal has a dedicated purpose:
„
Input 1—Either a transparent alarm link with the output relay (default) or PTL
(push-to-listen) audio transmission mode. To switch between the two, see page 37.
„
Input 2—Push-to-talk (PTT) audio transmission mode.
„
Output—Relay for the input 1 signal in alarm mode.
You cannot program audio control and alarms at the same time, since input 1 is used in
both contexts.
Audio
The S1100 device supports two audio modes: full duplex and half-duplex bidirectional audio
(that is, PTT/PTL).
In full duplex, audio is played continuously; the I/Os are available for alarms.
