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.
