Appendix F - The Unit Connectors

This section provides an overview of the product connectors, namely:

•1 x RS-232 Serial Connector

•2 x I/O Connectors (I/O-A and I/O-B)

•1 x DC-Iris Connector

•1 x BNC Video Output

•1 x Ethernet network connector (RJ-45)

The RS-232 Serial Connector

In the absence of a local network connection, a single 9-pin D-sub connector provides a

dedicated physical interface for connecting a modem or computer to the AXIS 2420. This

RS-232 interface supports modem speeds of up to 115kbps and effectively allows the AXIS

2420 to operate as a standalone unit independent of any computer network. So, when a

local network connection is unavailable at the point of installation, you can simply

connect your PC to this connector and use the supplied Null Modem Cable to initially

configure your product. If you intend using the AXIS 2191 Audio Module with your

network camera, then this is the connector to use.

Note: The Axis Camera Division maintains a list of all supported modems. Please visit our Website at

www.axis.com for this and other late information on our products.
