Appendix D - The RS232 Interface

As a complement to the information provided in Pan Tilt Settings, on page 31, this appendix

discusses the functionality of the RS232 serial interface and provides detailed instructions on how

to install a standalone Pan/Tilt device to the AXIS 2400 Video Server.

Important!

Two 9 pin D-sub connectors provide the physical connection for the RS232 serial interface of the

AXIS 2400. These connectors are provided for connecting accessory equipment; typically

standalone Pan/Tilt devices for remote positioning of connected video cameras.

The Physical Connector

A diagram of an RS232 connector and the AXIS 2400 pin assignment table are detailed below.

Notes: The pinout is different for each supported serial port

NC = Not connected

The Videmech driver is the only External Pan Tilt device (standalone device connecting to a fixed video

camera without inherent PTZ support) supported directly by the AXIS 2400. Unless stated to the con-

trary, Pan Tilt devices are assumed to be in-built within the video camera where referred to in this doc-

ument.
