7. Setting Up the RS-232 Link
The CS4000 Mini Controller with Ethernet can be connected to a laptop computer and serve a
stand-alone unit. This chapter describes the steps you must take to create this connection:
• Setting up Visual Supervisor for a stand-alone controller
• Using RS-232 cables
Setting Up Visual Supervisor
Install Visual Supervisor on the laptop computer that will be attached to the CS4000 Mini Controller.
During installation of Visual Supervisor on the computer, the installation program will give you the
choice to install Visual Supervisor in permanent or portable mode. You must select portable mode. To
find out details describing how to install Visual Supervisor, refer to the Visual Supervisor User’s Guide
(part number 39-30-34823). There is no requirement to edit VSMain.ini.
Using RS-232 Cables
The type of cable used to connect the laptop computer to the controller is known as a null modem
cable (part number 41-41-0109FN). To attach the laptop computer to the controller, insert the RS-232
cable into the RS-232 port on the bottom panel of the controller and insert the other end into the
RS-232 compatible port on the laptop.
