RS-232 Operation
Overview
The CS1922M / CS1924M’s built-in bi-directional RS-232 serial interface
allows system control through a high-en d control ler or PC. RS-232 serial
operations in a CS1922M / CS1924M installation are managed via
HyperTerminal sessions on systems that are running Windows. In order to use
this feature to send commands to the CS1922M / CS1924 M, yo u 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 CS1922M / CS1924M user manual.
Setup
Install a HyperTerminal application on a comput er that is not pa rt of the
installation, which will be used to control the swit ch via the RS-232
connection. HyperTerm in a l appli cations 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 to connect a computer’s serial port to the
serial port on the CS1922M / CS1924M, as shown below:
