1.3 Live Mode Overview
The iVu BCR can be configured to evaluate one or more of the supported barcode types and can look for a specific number
of barcodes from 1 to 10. The barcode types are selected on the integrated touch screen by accessing Main Menu >
Inspection > Barcode Type. The barcode count is selected on the touch screen by going to Main Menu > Inspection >
Barcode Count.
1.3.1 Read/No Read, Pass/Fail, Match/No Match
• A Read condition occurs when the configured number of barcodes are found in a scan. These barcodes must be
error-free.
• A No Read condition occurs when the configured number of barcodes are not found in a scan.
• If the sensor is configured where Data Compare is disabled, Pass and Fail are the same as Read and No Read.
• If the sensor is using the Data Compare feature, Pass indicates that a good barcode was found and the data
compared.
• If the sensor is using the Data Compare feature, Fail indicates that either no good barcode was found or the data
did not compare.
• A Match condition occurs when the required number of barcodes are found and the compare is successful.
• A No Match condition occurs when the required number of barcodes are found, but the compare is not successful.
1.3.2 Trigger Modes
The iVu BCR has four trigger modes that determine how the sensor captures and processes images:
• External - Single
• Continuous
• External - Gated
• Command
1.3.3 Compare Data
The iVu BCR has a data compare feature for comparing read barcode data against reference data. Data can be manually
entered by navigating to the Main Menu > Inspection > 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.
The sensor tries to compare full length of this string with the data read from the barcode. If not equal, the inspection is
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.
1.3.4 Output 1 and Output 2
The sensor has two output signals that you can configure for Pass, Fail, Read, No Read, Match, No Match, System Error,
and Missed Trigger. The default settings are Pass for Output 1, Fail for Output 2.
iVu Barcode Reader (BCR)
12

NOTE: For all outputs, the default setting is Latched, which means that the signal is active until the
results of an inspection cause a change in the signal output. If Pulsed is selected, the default pulse
width is 50 ms.
1.3.5 Remote Teach
The Remote Teach function is a method of remotely updating inspection parameters while the iVu sensor is running. The
sequence of events for executing a Remote Teach are:
1. With the sensor Ready (see Installation on page 4), pulse the Remote Teach line.
2. The sensor recognizes that the Remote Teach line has been pulsed and waits for the next valid trigger.
3. At the next valid trigger, Ready goes inactive (the Green Ready LED shuts OFF), and the sensor acquires a new
image.
