1-10 PC208W, Version 3.3, Instruction Manual
File Format
PC208W supports three formats for the collected data:
•
ASCII, Comma Separated - This is the best choice for most applications.
Data values are separated by commas with no leading zeros and with each
array on a new line. This is the easiest format for importing into other
software; it’s reasonably compact and can be viewed directly.
•
ASCII, Printable - Numbers are aligned in columns and preceded by a 2-
digit ID indicating the array position. The column IDs repeat after 100
columns. Each row in the data file has up to eight columns before a new
line is started. This format is easiest to read manually (i.e., printed copy)
but is difficult to import into spreadsheets and other applications. SPLIT
can be used to convert to other formats. This format is ambiguous for data
arrays of 100 or more and should be avoided for purposes other than
printing.
•
Binary - This format is the most compact on the PC but must be converted
before it can be used. SPLIT can be used to convert to other formats.
1.2.6 Setup Safety Tips
You can freely move between the different PC208W windows. This means
you can open the SETUP screen while you are communicating with a
datalogger or using one of the other PC208W programs. However, if you
change the setup, PC208W may hang up calls in process and not call again
until the changes are saved. It does this to prevent data storage pointers from
being corrupted. Therefore, it is better to avoid changing the setup while
communicating with a datalogger that will be affected by the change.
You must click on Save Edits for the device settings to take effect and continue
any scheduled communications. You will also be prompted to Save Edits if
you close the Setup window or PC208W if you have not yet saved the new
device settings. If you find you have made a mistake while changing device
settings but have not yet saved the edits, you can return to the previous
configuration by clicking Cancel Edits. This only works for one previous
setup because otherwise, PC208W may have called a datalogger and changed
data storage pointers, making a return to previous settings unreliable.
You may drag and drop devices from one connection to another. If the place
where you drop a device is ambiguous, PC208W will ask whether to place the
moved device as a child or at the same level.
PC208W uses the computer clock to control some of its timing. Changing the
PC clock while connected to a datalogger may cause unexpected results in
PC208W.
