There are several commercially available software packages, which can read
RS232 data and enter the data into a computer program such as a word
processor (to create a text file) or spreadsheet (to tabulate and plot the data).
Consult your laboratory supply dealer regarding the latest software available.
The following describes how to use an IBM compatible computer with Hyper
Terminal™ software (included with Windows® 95, 98, XP or 2000 operating
systems) to collect the RS232 data from your freeze dry system:
1.
Make sure that the freeze dry system is properly connected to the
communication port on the computer.
2.
Open Hyper Terminal™ software.
i) Windows® 95 or 98 use:
START/PROGRAMS/ACCESSORIES.
ii) Windows® 2000 or XP use:
START/PROGRAMS/ACCESSORIES/COMMUNICATIONS
The first time Hyper Terminal™ is opened a dialogue box requesting an
area code and phone number will appear. Enter the appropriate numbers
and continue.
