Appendix D - The Unit Connectors
This section provides a detailed overview of the two supported product connectors: the Serial Connector and the IO Connector. It also includes connection diagrams for a simple door switch and an LED output, as well as a more complete schematic diagram describing how the AXIS 2100 is connected for a typical application.
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 2100. 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.
The Physical Connector
