CHAPTER 9. RS232 COMMUNICATION
9.1 INTRODUCTION
The RS232 communication feature permits viewing or changing of Control Panel menu options
and also provides access to data logs showing Event Time Line, Fault and Sensor log displays.
The RS232 port on the front panel of the C-More Control Box (Figure 3-1) can be interfaced to a
laptop computer or other suitable terminal using a RS232 adapter cable. RS232 communication
can be accomplished using any “Dumb Terminal” emulation, such as “PuTTY” which is not
included with Microsoft Windows, but can be downloaded for free on the internet. Source and
instructions for using Putty are provided here:

You can use PuTTY to logon to remote computers as well as run a single command on a
remote server. PuTTY does not need to be installed, so just clicking the downloaded executable
will start it.
