Cygnus 2 Operating Manual
3.5.7 USB Storage Device
The USB port allows storage of all parameter information, screen shots as well as
automatic datalogging information to a storage device. The maximum number of
files which may be stored depends on the storage device memory size. Cygnus 2
is limited to displaying 120 files as 8 pages of 15. The directories are Config,
Datalog and Screen Shot.
The parameter set may be stored under a new or existing filename and retrieved
from an existing file. A file containing the Cygnus 2 parameter set is referred to as
a configuration file. Datalog information will be saved only if the USB Datalog
Format setting in the Datalog page of the USB Storage screen is set to Comma or
Page.
Multiple files may be contained on one storage device. Filenames may be eight
characters long; extensions are used to differentiate between configuration files,
screen shots and datalogging files. All files must be contained in the appropriate
directory. Storage/retrieval from sub-directories is not allowed for screen shots and
datalog files
Cygnus 2 supports the writing of filenames using alphanumeric characters selected
using the cursor keys. Characters A through Z and numbers 0 through 9 inclusive
are available. Cygnus 2 has the ability to display the files contained on the memory
stick. A scrolling feature is enabled to view those filenames which cannot fit as
indicated by +++ on the screen. Error messages include: Disk Full; File Not Found;
Disk Write Protected; Media Error; Disk not Found; File is Read Only.
Datalog files are automatically named using the Date and Material number. See
section 3.5.9, Datalog, on page 3-35 for the Datalog string details.
Screen shots are named as DDMMYYXX or MMDDYYXX depending on the date
format setting. XX is a number that increments 0-99, resetting to 0 every day.
NOTE: A File Access Code parameter is enabled when Cygnus 2 has a Program
lock code set. By entering a File Access Code, the Cygnus 2 parameters
can be saved to, or retrieved from, the USB storage device only without
entering the Program Lock Code. (See Chapter 6, General Parameters.)
Do not remove the USB storage device from the
Cygnus 2 while a Save or Retrieve operation is taking
place.
