2: Configuring and Installing the Device
10 Verint Video Solutions
Installing the Device
When your device is successfully configured, it is ready to be installed in its final location.
To install the device:
1. Plug the video cable of the camera or monitor to the video BNC connector on the
device.
2. Plug the network cable into the LAN 10/100 Ethernet connector on the device.
3. Power the device.
4. If required, connect the serial port of the device to the camera (see next).
Note: The S1900e-AS device may heat more than one without analytics capabilities.
Performing Serial Connections
The S1900e device supports only the RS-422 and RS-485 asynchronous protocols. For any
other protocol, you may need a converter.
RS-422/485
Most target devices (keyboards, PTZ cameras, monitors) use the RS-422/485 protocol for
communication.
To use the RS-422/485 functionality, you need to:
1. Connect a twisted pair cable to the multipole connector on the front of the device. The
connector gives access to the Tx+, Tx-, Rx+, Rx-, and ground signals.
2. Select the right operating mode (RS-422 4 wires, RS-485 2 wires, or RS-485 4 wires)
using SConfigurator or a video management software.
To properly make the connection to a four-wire RS-422 or RS-485 serial device, use the
following scheme (where the Tx connectors are for input and the Rx connectors are for
output):
For a two-wire RS-485 connection with a Nextiva device:
1. Create the Data- signal by shorting the Rx- and Tx- pins together.
2. Create the Data+ signal by shorting the Rx+ and Tx+ pins together.
