This information is displayed when setting the baud rate (see section 10.1)
10.4 Communication and Statistical Software
Communication between the
90-FL
and a PC can be handled with any RS232 communication
software. A TPS communication software package for Windows
is optionally available (part
number 130086).
Once the data is saved to disk, the next problem is how to use it. The data sent by the
90-FL
is
formatted in fixed-width columns that can be imported by programs such as Microsoft
®
Excel
®
and
Lotus 123
®
.
Help on importing the data into Microsoft
®
Excel
®
is provided in section 10.8 and the “excel.txt”
file in the folder where you installed the WinTPS program.
