Appendix E - 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 2110 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 2110. 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
A single 9-pin D-sub connector provides the physical connection for the RS-232 serial
interface of the AXIS 2110. This interface is for use with an external modem and is
suitable for speeds of up to 115kbps.
A diagram of the RS-232 connector's pinout information is shown below.
