CHAPTER 9 – RS232 COMMUNICATION
CHAPTER 9. RS-232 COMMUNICATION
9.1 INTRODUCTION
The RS-232 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 RS-232 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 RS-232 adapter cable. RS-232
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:
9.1.1 Acquiring the PuTTY Application
Download
the putty.exe program
to
your
desktop
from:
www.chiark.greenend.org.uk/~sgtatham/putty/download.html
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.
1.1.1
Logging on to a Remote Machine Using PuTTY
To use PuTTY to logon to a remote machine, bring up the PuTTY application by double-clicking
its icon. You will see the main window as shown in left image of Figure 9-1.
Figure 9-1: PuTTY GUI: Basic Serial Session (L) and Serial Options (R)
In Serial mode, text typed into the PuTTY window will be sent straight out of your computer's
serial port, and data received through that port will be displayed in the PuTTY window.
To create a Serial connection, click the radio button labeled Serial. The Serial line and Speed
fields will then be automatically filled in as shown in left image of Figure 9-1, but will allow you
to specify the serial line to use (if your computer has more than one) and what speed (baud
rate) to use when transferring data. For further configuration options (data bits, stop bits, parity,
flow control), you can use the Serial Configuration panel (right image in Figure 9-1) by
selecting "Serial" in the left navigation pane.
