RS-232 Operation
Overview
The CS1842 / CS1844’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 CS1842 / CS1844 installation are managed via HyperTerminal sessions on
systems that are running Windows. In order to use this feature to send
commands to the CS1842 / CS1844, you must first download and install a
HyperTerminal application.
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-45 to DB-9 serial adapter to connect a computer’s serial port to the
DCC Port on the CS1842 / CS1844, as shown below:
Note: 1. Slide the DCC Switch to the S position (Secondary) to allow the
KVM switch to receive RS-232 commands.
2. The unit used in the diagram below is CS1844, the procedure for
connecting CS1842 is identical with fewer KVM ports.
