iVu Plus BCR User's Manual

1.2.3 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 navigating to 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 uses the new data for comparison with subsequently read barcodes. If the previous
input data contained any masked characters, Remote Teach retains 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, 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.

1.2.4 Output 1, Output 2, and Output 3

The sensor has three 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, and Pass for Output 3.
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.

1.2.5 Serial and Ethernet Output

The iVu Plus communicates with other devices via Ethernet or a UART serial communications port (RS-232). In order to
establish an Ethernet connection to the sensor, the external device must be configured with the correct IP address and TCP
port to communicate. To use the serial communications connection, port settings for baud rate, data bits, parity, and stop
bits must be configured on the iVu Plus to match the settings of the external device.
The iVu Plus BCR RS-232 port or ethernet port can be used to output barcode data to other applications. To access the
Data Export screen, go to Main Menu > System > Communications > Data Export. The user can enable or disable this
feature. When enabled:
• if the sensor is configured for either External-Single or External-Gated trigger modes, every trigger results in the
transmission of output data (if the sensor does not successfully read a barcode, the output will be NO_READ).
• if the sensor is configured for Continuous trigger mode, the sensor transmits output barcode data only upon a
successful read.
To access the Serial Output screen, go to Main Menu > System > Communications > Serial I/O.
When RS-232 serial output is enabled, the user can configure:
• Serial Port Settings (listed below)
• Type of Data to Export (listed below)
• Output Format (listed below)
To access the Ethernet Output screen, go to Main Menu > System > Communications > Ethernet I/O.
When ethernet output is enabled, the user can configure:
• IP Address, Port number, Subnet Mask, and Gateway
• Type of Data to Export (listed below)
• Output Format (listed below)
