8.3.4.3 External Memory Power-up
Uploading a CR800 operating system (OS) 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:
drive. The steps to copy
files from the external memory drive to the datalogger are:
1. Place a powerup.ini file on the external memory device along with the OS or
program file to be copied to the datalogger.
2. Connect the external device to the CR800 and then cycle power to the
datalogger.
This simple process results in the specified file being automatically uploaded to
the CR800 with optional run attributes, such as Run Now, Run on Power Up, or
Run Always set for individual files. It is also possible to simply copy a file to a
specified drive with no run attributes or to format a memory drive. Powerup.ini
options also allow final data storage management on CF cards comparable to the
datalogger support software
(p. 76) File Control feature. The CRD: drive has
precedence over the USB: drive.
Including a powerup.ini file with the OS / program file on the external device,
connecting the external device to the CR800, and then cycling power, will result
in the file automatically uploading to the CR800 and running. Powerup.ini
options also allow final-data storage management comparable to the support
software File Control
(p. 431) feature. The
Caution Test Power-up options in the lab before going to the field. Always carry
a laptop or palm PC into difficult- or expensive-to-access places as backup.
Power-up functions include
• Sending programs to the CR800.
• Optionally setting run attributes of CR800 program files.
• Sending an OS to the CR800.
