command, options to preserve
(not erase) or not preserve (erase) data are presented. The logic in the following
example summarizes the disposition of CR3000 data depending on the data
preservation option selected.
if "Preserve data if no table changed"
keep CF data from overwritten program
if current program = overwritten program
keep CPU data
keep cache data
else
erase CPU data
erase cache data
end if
end if
if "erase CF data"
erase CF data from overwritten program
erase CPU data
erase cache data

8.8.5.4 Powerup.ini File — Details
Uploading a CR3000 OS
(p. 547)
file or user-program file in the field can be
challenging, particularly during weather extremes. Heat, cold, snow, rain,
altitude, blowing sand, and distance to hike influence how easily programming
with a laptop or palm PC may be. An alternative is to carry the file to the field
on a light-weight, external-memory device such as a USB:
(p. 613)
or CRD:
(p. 613)
drive. Steps to download the new OS or CRBasic program from an external-
memory drive are:
1. Place a text file named powerup.ini, with appropriate commands entered in
the file, on the external-memory device along with the new OS or CRBasic
program file.
2. Connect the external device to the CR3000 and then cycle power to the
datalogger.
This simple process results in the file uploading to the CR3000 with optional run
attributes, such as Run Now, Run on Power Up, or Run Always set for
individual files. Simply copying a file to a specified drive with no run attributes,
or to format a memory drive, is also possible. Command options for
powerup.ini options also allow final-storage memory management on memory
cards comparable to the datalogger support software
(p. 90)
File Control feature.
Options for powerup.ini also allow final-storage memory management
comparable File Control
(p. 539).
Note that the CRD: drive has priority over the
USB: drive.
Caution Test the powerup.ini file and procedures in the lab before
going to the field. Always carry a laptop or mobile device (with datalogger
support software) into difficult- or expensive-to-access places as backup.
