The term “device” refers to one of the six memory elements used by the
CVIM2 system. The mnemonic name for each memory “device” appears in
the device list, as shown in Figure 11.1 on page 11–1.
The six devices are described briefly as follows:
•
EE –– This is a 64K–byte internal EEPROM, an electrically erasable,
programmable, read–only memory. It is typically used to store
configuration files, the password file, tool configurations, and acquisition
configurations.
•
FL –– This is an internal “flash” memory. It is used to store files that are
used by the CVIM2 system software, and you cannot alter or delete these
files.
•
MC –– This is an external memory card, which is a battery–backed
memory that inserts into a slot in the CVIM2 front panel. It is typically
used to store configuration files; however, it can be used to store any file
from any other device. The file size is limited only by the amount of free
space available on the card. Memory cards are available in sizes from
64K to 512K bytes.
•
V1 –– This is an internal “flash” memory. The CVIM2 system uses it to
store “help” files, string files, dictionary files, and files created by
external packages.
NOTE: You should not use the V1 device as a backup storage device for
your files, since those files will be deleted when new revisions of the
CVIM2 firmware are loaded.
•
V2 –– This is an internal “flash” memory. It is used to store foreign
language dictionary files. You may use
V2 as a backup storage device for
tool files, configuration files, and image files.
•
RM –– This is a portion of the internal random access memory (RAM),
up to 32K bytes in size, which is intended to be used for temporary file
storage. Its contents are lost when power is removed.
View
The view function enables you to view the contents of one of the files listed
in the panel. When you pick the
button after highlighting one of the
files in the file list, the “ Viewing file ” panel appears, as shown in Figure 11.4
(page 11–7).
This function is intended for viewing characters and strings that are in
“printable” ASCII text form, such as the abbreviations and codes that
represent the inspection tool configuration in the “
Tools1 ” file in
Figure 11.4. (If an image or dictionary file were viewed, the “ Viewing file ”
would display the file in both hexadecimal and ASCII form.)
