Nextiva S1100w User Guide
Installing an Antenna
If you bought a high gain antenna, install it after the S1100w is in place. The antennas
provided by Verint Video Intelligence Solutions are designed to be mounted on a mast or
pole of 2–3 inch (5–7.5 centimeter) diameter.
To install an external antenna:
1. Install the antenna above the S1100w device. If you bought your antenna from Verint
Video Intelligence Solutions, use the supplied pole mount bracket.
2. Screw the SMA connector of the antenna cable to the S1100w antenna port and tighten
it with a 0.25-inch (0.6 centimeter) 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 antennas of the S1100w and access point so that they have a clear
RF line of sight.
5. To improve the signal level between both devices, use the antenna alignment utility
from SConfigurator.
Performing the RS-422/485 Serial Connection
The Nextiva edge devices support only the RS-232, RS-422, and RS-485 asynchronous
protocols. For any other protocol, you may need a converter.
Warning: At any time there must be only one serial peripheral connected to the edge
device. For instance, when configuring the device through a COM port of the
computer, you must unplug any RS-422/485 peripheral.
RS-422/485
You use the CAB9P cable to properly connect the device to an RS-422 or RS-485 peripheral.
Here is the wiring scheme for the four-wire RS-422 or RS-485 protocol:
Cable Peripheral
Signal name Wire pair Wire color Signal name
Rx+ green/black green Rx+
Rx- black Rx-
Tx+ yellow/black yellow Tx+
Tx- black Tx-
Signal ground brown/black brown Signal ground
