RS-232 Operation
Overview
The CS261 / CS261TK’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 CS261 / CS261TK installation are managed via HyperTerminal sessions
on systems that are running Windows. In order to use this feature to send
commands to the CS261 / CS261TK, you must first download and install a
HyperTerminal application. For more detailed instructions and information
about each of the commands provided in this manual, please refer to the
original CS261 / CS261TK user manual.
Setup
Install a HyperTerminal application on a computer that is not part of the CS261
/ CS261TK setup, which will be connected and used to control the CS261 /
CS261TK via RS-232. HyperTerminal applications can be download from the
internet, and many operating systems are embedded with HyperTerminal
applications.
Hardware Connection
Use an RJ-11 to DB-9 serial adapter (ATEN model no.: LIN5-04A2-J11G) to
connect the computer’s serial port to the Serial port of the CS261 / CS261TK,
as shown below:

Console Login - HyperTerminal
Once a physical connection from the computer to the CS261 / CS261TK has
been made, you can establish a HyperTerminal session using the instructions
below.
1. Open the HyperTerminal application, and configure the port settings for
the appropriate COM port number, then click OK.

RS-232 Commands
After you login via HyperTerminal (see Console Login - HyperTerminal,
page 4), you can use the instructions below to send RS-232 commands to
control the CS261 / CS261TK from a remote system.
When the RS-232 link is opened, the CS261 / CS261TK will no longer accept
commands from front panel buttons or most of hotkey functions (excluding
hotkey switching mode, console status and turn off/on the other monitor and
audio).
For more detailed instructions and information about each of the RS-232
commands listed below, please refer to the original CS261 / CS261TK user
manual.
Verification
After entering a command, a verification message appears at the end of the
command line, as follows:
Response Message Description
command OK Command or parameter is correct.
command incorrect Command or parameter is incorrect.
