Overview
The CS1922M / CS1924M’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 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 / CS1924M, 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 CS1922M / CS1924M 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 CS1922M / CS1924M, as shown below:
Note: The unit used in the diagram below is CS1924M, the procedure for
connecting CS1922M is identical with fewer KVM ports. RS-232 Pin
Assignments
Pin assignments for the CS1922M / CS1924M’s rear RJ-11 Serial Port that is
used for connecting to a serial terminal are given in the table, below:
Note: This RJ-11 female connector is 4P4C.
Pin | Assignment |
---|---|
1 | TXD: Transmit Data |
2 | RXD: Receive Data |
3 | N/A |
4 | GND: Signal Ground |
Console Login – HyperTerminal
Once a physical connection from the computer to the CS1922M / CS1924M has been
made, you can establish a HyperTerminal session using the instructions below.
-
Open the HyperTerminal application, and configure the port settings for COM1 port, then click OK. Bits per Second: 19200, Data Bits: 8, Parity: None, Stop bits: 1, Flow Control:
None. -
After configuring the port settings you must enable serial control on the switch by typing the command: Open + [Enter].
RS-232 Commands
After you login via HyperTerminal (see page 5) use the instructions below to
send RS-232 commands to control the switch from the computer.
When RS-232 control is enabled via the Open + [Enter] command, the CS1922M /
CS1924M’s front panel pushbuttons and hotkeys (excluding the mouse cursor
shift and monitor layout hotkeys) will be disabled, until the serial
connection is closed.
For detailed information about the controls listed in this guide, please refer
to the CS1922M / CS1924M user manual.

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.
