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 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
In the absence of a local network connection, the RS232 serial connector provides a physical interface for connecting a modem or computer to the AXIS 2110. This means that the AXIS 2110 can operate as a standalone unit - independent of any computer network. 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.
The Physical Connector
A single 9 pin
A diagram of the RS232 connector’s pinout information is shown below.
