CHAPTER 9. RS232 COMMUNICATION

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.

NOTE

The information in this chapter does not apply when implementing BST.

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:

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.

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.
