The RS-232 Serial Connectors
In the absence of a local network connection, the 9-pin D-sub connector COM2 provides a
dedicated physical interface for connecting a modem or computer to the AXIS 2460. This
RS-232 interface supports modem speeds of up to 115kbps and effectively allows the AXIS
2460 to operate as a standalone unit, independent of any computer network. The
maximum cable length for RS-232 should not exceed 15 meters (50 feet).
If a local network connection is unavailable at the point of installation, you can simply
connect your PC to this connector using the supplied
Null Modem Cable
. This will allow
you to complete the initial configuration of your product.
Both serial connectors (COM1 and COM2) can be used for running Generic TCP/IP or
Generic HTTP applications. The pinout for COM1 is different to that of COM2.
Note:
Axis Communications maintains a list of all supported modems. Please visit our Website at
www.axis.com for this and other late information on our products.
