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.
