3.16 Downloading Stored Data to a Personal Computer
Using the monitor’s PC DUMP feature (page 17), the last 200 SF
6
gas readings that were stored in
memory can be downloaded to a personal computer in ASCII text, comma-delimited format, which can
then be imported into most spreadsheet programs for analysis.
The following describes how to download data to a computer using Windows® HyperTerminal as the
communications program. If a different operating system and/or communications program is being used,
then consult the appropriate instruction manuals for those products.
1. Install serial data cable P/N 104-4027 (straight through, 6 foot, DB9 male to DB9 female) between
the computer’s COM port and the analyzer’s RS-232 connector. (For computers having a 25-pin
COM port, either use a 25-pin to 9-pin adapter, or use a serial cable with appropriate connectors
on each end.)
2. At the computer, start HyperTerminal by doing one of the following:
• If HyperTerminal has already been set up to communicate with the SF
6
Monitor, then click Start,
point to Programs, point to Accessories, point to Communications, click HyperTerminal, and
double-click the file name or icon that has been associated with the SF
6
Monitor.
• If HyperTerminal has never been run in association with the SF
6
Monitor, then a new
HyperTerminal connection needs to be made as follows:
a) Click Start; click Run. In the Run box type “hypertrm.exe” and click OK. The New
Connection dialog box should appear.
b) Type in a New Connection Name such as “SF6”. Click OK to select the default icon (if
desired, select a different icon before clicking OK). The Connect To dialog box should
appear.
c) Click the Connect using drop-down menu and choose the COM port to which the analyzer
is connected. Then click OK to display the COM Properties dialog box for that COM port.
d) Set Port Settings to:
- Bits per second: 19200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
Then click OK to display HyperTerminal’s main window.
e) Click File; click Save. This creates a file with an .ht extension in the folder C:\Program
Files\Accessories\Hyper Termina, using the name that was entered in Step b.
3. After HyperTerminal is running: click Transfer, click Capture Text, and then click Start to accept
the default drive\directory\filename to which all received data will be stored as an ASCII text file.
Note: By default, the captured text file will be stored on the hard drive at C:\Program
Files\Accessories\HyperTerminal\CAPTURE.TXT. If desired, click Browse to select a different
drive, directory and filename. The next time data is captured, it will be stored under the same
location and filename.
Tip: Changing the filename extension to “CSV” (comma separated variable) will allow the file to be
directly opened in the spreadsheet program. For example, double clicking the filename
CAPTURE.CSV in Windows Explorer will automatically start Microsoft Excel and load the file.
