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. 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 downloaded 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.
- Open the HyperTerminal application, and configure the port settings for the appropriate COM port number, then click OK.
- Bits per Second: 19200, Data Bits: 8, Parity: None, Stop bits: 1, Flow Control: None.
- When configured correctly a login prompt like the one below appears:
RS-232 Commands
After you log in 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 the hotkey functions (excluding hotkey switching mode, console status,
and turning 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.
