Appendix D - The RS232 Interface
As a complement to the information provided in
Pan Tilt Settings,
on page 32, 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 2400/2401 Video Server.
Two 9 pin D-sub connectors provide the physical connection for the RS232 serial interface of the
AXIS 2400/2401. 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 2400/2401 pin assignment table are detailed
below.

Camera Positioning
The AXIS 2400/2401 can control the position of connected cameras in three different ways:
•
Pan Tilt Control using the Web Administration Tools:
where, the position of the selected video
camera is controlled using a standard Web browser.
•
Generic Control using CGI parameters:
enter the positioning data as a CGI command directly
into your Web browser Location/Address (URL).
•
Generic control using a TCP client:
using a TCP client-application to control the position of
the chosen camera.
