Bar Code Travel Direction

Bar codes can be scanned in a static location, or more commonly with on-line scanner/verifiers, they can be scanned while moving through the laser beam. The illustration below shows the two directions a bar code can travel through the laser beam. They are designated “picket fence” and “ladder” directions.

Picket Fence Travel

Direction

Ladder Travel Direction

The SV unit must be programmed for the direction of travel of the codes being analyzed. If the codes are being scanned in a static condition, use the picket fence travel direction.

Bar Code Travel Speed Considerations

A bar code should be present in the beam for at least five scans for the most reliable operation. The SV Series performs a minimum of 100 scans/analyses per second. At that rate, each analysis is accomplished in 10 milliseconds maximum. Therefore, a bar code must be in the beam for at least 50 milliseconds to be reliably analyzed. Some SV models have higher minimum scans/analysis; therefore a bar code must be in the beam for less amount of time for those models.

SV Scanner/Verifier Setup Procedure

Installation of an SV scanner/verifier requires proper mounting position, output port configuration(s), and LED configurations to ensure the reliable and accurate operation. This section describes the procedures for using ScanView to ensure proper SV setup and installation.

Each SV unit has a label showing the specified mounting distance and angle for its particular scanner. Follow the steps below to ensure the SV unit is properly mounted and programmed.
