The RS-232 Interface AXIS 2400+/2401+ Admin Manual

Appendix F - The RS-232 Interface

The AXIS 2400+/2401+ has two 9-pin D-sub connectors, providing the physical interface for

two RS-232 ports, used for connecting:

• accessory equipment; such as stand-alone Pan/Tilt devices for remote positioning of con-

nected video cameras

• any standard modem for use in remote applications

• the AXIS 2191Audio Module, as described on page 28.

As a complement to the information provided in Pan Tilt Settings, on page 23, this

appendix describes how to install a standalone Pan/Tilt device to the AXIS 2400+/2401+

Video Server.
