Appendix D - The Unit Connectors

This section provides a detailed overview of the two supported product connectors; namely the Serial Connector and IO Connector. It also includes a schematic diagram describing how the AXIS 2120 is connected for a typical application:

The Auto Iris Connector

The AXIS 2120 is supplied with a varifocal DC Iris lens that automatically regulates the amount of light entering the camera, and provides a distortion free wide-angle zoom.

The power and control signalling required for automatically adjusting the lens is supplied by the Auto Iris Connector that attaches to the lens via a connecting cable. The connector is located at the base of the camera, as illustrated below:

DC-Iris cable. Connected to the lens upon delivery, this cable supplies the power and electronic signal- ling to the lens from the DC Iris connector.

Below: DC Iris connector - with the cable removed.

The AXIS 2120 is delivered with the Auto Iris cable already attached to the connector, and with the Auto Iris functionality enabled by default. Should you experience any problem with overexposure or white balance adjustment in your camera, check that the cable is firmly attached to the Auto Iris connector. Otherwise, the Auto Iris function requires no further intervention from the user. If you are unable to immediately resolve any apparent fault, refer to Appendix A - Troubleshooting.

The Serial Connector

The serial connector can be used for several purposes. In the absence of a local network connection, the serial connector provides a physical interface for connecting a modem or computer to the AXIS 2120. When a local network connection is unavailable at the point of installation, connect your PC to this connector using the supplied Null Modem Cable to initially configure your product. If you intend to use the AXIS 2191 Audio Module with your network camera, then this is the connector used for connecting it.
