The Calculations/File IO tab contains controls, as shown in
settings currently configured in the PAC1921 to allow quick reconfiguration at any time.
FIGURE 4-16:
To save configuration settings, configure the PAC1921 as desired, then display the
Calculations/File IO tab. The "FF Reg File Path" box defaults to where the GUI soft-
ware is installed. To change the location, type in a path, or click the folder icon to use
a Windows
file will be saved. The file should be named with the.txt extension or similar text file
format. Once a file name and location have been chosen, click the Save switch, and
the file is saved.
Note:
The data is saved in two columns, separated by tabs. The first column is the register
address and the second column is the register data.
Once a file is saved, it can be recalled at any time by selecting the file in the "FF Reg
File Path" box and clicking the Load switch.
Click the Chip Defaults switch or press the <F6> function key on the keyboard to
reload register defaults on the PAC1921.
