RS-232 Operation
Overview
The CS1822 / CS1824’s built-in bi-directional RS-232 serial interface allows
system control through a high-end controller or PC. RS-232 serial operations
in a CS1822 / CS1824 installation are managed via HyperTerminal sessions on
systems that are running Windows. In order to use this feature to send
commands to the CS1822 / CS1824, you must first download and install a
HyperTerminal application. For detailed instructions and information about
each of the commands provided in this manual, please refer to the CS1822 /
CS1824 user manual.
Setup
Install a HyperTerminal application on a computer that is not part of the
installation, which will be used to control the switch via the RS-232
connection. HyperTerminal applications can be download from the Internet,
and many operating systems are embedded with HyperTerminal applications.
Hardware Connection
Use a RJ-11 to DB-9 serial adapter (LIN5-04A2-J11G) to connect a
computer’s serial port to the serial port on the CS1822 / CS1824, as shown
below:
Note: The unit used in the diagram below is CS1824, the procedure for
connecting CS1822 is identical with fewer KVM ports.

Open / Close
The Open and Close commands allows you to start and end the link between
the computer sending RS-232 commands and the CS1822 / CS1824. When the
link is open, the CS1822 / CS1824 only accepts RS-232 commands and will
not respond to front panel pushbuttons and hotkeys (excluding the mouse
cursor shift and monitor layout hotkeys) – until the link is closed. The link
starts with the open command and ends with the close command or after 2
minutes if no command is sent. The default value is close.
