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, as described on page 11
• the AXIS 2191Audio Module, as described on page 31.
As a complement to the information provided in Pan Tilt Settings, on page 26, this
appendix describes how to install a standalone Pan/Tilt device to the AXIS 2400/2401
Video Server.
