Match to File
This feature compares the data decoded within a sector to the data on a file created by the user. Note that the
format of the file must be a comma-separated values (CSV) file.
Any number of sectors can be set to use “match to file”. If all “Match to file” sectors are marked as “Duplicates
allowed”, the system will not be able to relocate within the data file if stopped during a run. This means the LVS-
7000 is not able to automatically find its place within a run on a job if stopped and restarted. If this occurs, you
must access your file and make the first number in the file be the first expected number in the camera’s field of
view after pressing the run button. The associated hash files within the job heading must be deleted so they can
be recompiled at run time.
IMPORTANT: The “Match to file” feature has associated processing overhead; thus, it is
recommended to review all your options and use the “Match to file” feature as a last resort.
You must create the file to “Match To” on a per job basis . Tools are not provided in the LVS-7000 software to
accomplish this.
The format of the file must be as follows:

The format of the file must be a comma-separated values (CSV) file.

The order in which the data is stored is matched to the sector number in lowest to highest order that has
been selected to “Match to file”.

Headers are not allowed.
Example 1:
In the sample below, the LVS-7000 would expect to have two sectors per repeat that are “Matching to File”. The
file would show that it expects only 11 repeats of the label. Neither sector is expected to have duplicates. Due to
the processing overhead of “Matching to File”, the second sector could be set to perform a sequential check
instead of “Matching to File”.

Example 2:
In this sample, the LVS-7000 would expect to have two sectors per label repeat that are “Matching to File”. As
with the above sector, only 11 repeats of the label are expected; however, this sector has duplicates. The LVS-
7000 has processing penalties for “Matching to File”. Thus, with this example, it would be more cost effective to
match only the first sector to a file, as the second sector can be set to a fixed match string without the extra
processing required.
