CHAPTER 9 RS232 COMMUNICATION
9.1 INTRODUCTION
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 “Hyper Terminal”
which is included with Microsoft Windows. 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.
9.2 RS232 COMMUNICATION SETUP
Regardless of the terminal emulation utilized,
the following guidelines must be adhered to
when setting up the RS232 communication link:
1. Baud Rate – The baud rates which can be
used with the C-More Control Panel are:
2400
4800
9600 (Default)
19.2K
2. Data Format – The program must be set for:
8 data bits, 1 stop bit, no parity and either
Xon/Xoff or No flow control.
