Compare Data
The iVu Plus BCR has a data compare feature for comparing read barcode data against reference data. Data can be manually entered
by accessing the Main Menu > Inspection > Barcode > Data Compare > Set Data screen. Data of up to 3200 characters can be
entered. Additionally, the data compare feature provides for masking characters within the data.
There are two other ways to enter compare data:
• Importing the last read data while viewing the Set Data screen. The new data is effective on the first trigger that occurs after this
action.
• Using Remote Teach. When a Remote Teach occurs, the data of the first read barcode is saved as Data Compare input. Inspections
executed on the next trigger will use the new data for comparison with subsequently read barcodes. If the previous input data con-
tained any masked characters, Remote Teach will retain the masked characters only if the new data is of the same length as the
previous input data. If the length does not match, masking is removed.
The sensor tries to compare full length of this string with the data read from the barcode. If not equal, inspection will be marked as Fail.
NOTE: If the sensor reads more than one barcode in the field of view, only the first barcode data that the
sensor reads can be compared.
Setting up for Data Compare
This section describes how to set up the data compare feature. For this example, the reference data will be from a previously decoded
barcode.
1. Go to the Main Menu > Inspection > Barcode > Data Compare > Compare to Enable data compare.
2. Go to the Main Menu > Inspection > Barcode > Data Compare > Set Data , and click the Show last read data button.
