HandHeld Entertainment SV Series Calibration, Picket Fence Bar Code Positioning Specifications

Note: If using ~HO2, ensure the bar codes with short vertical gap are encoded with different data and only one code across is being analyzed in each scan.

Note: The slower of the two print speeds calculated above for bar height and gap height is the maximum recommended speed for picket fence travel.

Picket Fence Bar Code Positioning Specifications:

•Four codes across maximum

•Horizontal gap between codes: .5 inch (13 mm) minimum

•Maximum number of codes per sync period: 99

Ladder Direction

In ladder direction, one bar code at a time is usually in the beam. The amount of time the code is in the beam is a function of the total width of the code (including quiet zone), the length of the beam area that is used for scanning and the speed the code is travelling. The distance the bar code is in the beam is calculated by subtracting the bar code width from the length of the beam programmed to scan the bar code. (See "Setting Ladder Mode Scanning Length Using ScanView Software" on page 5-8.) Divide this difference by the amount of time the SV model requires to gather 5 scans to get the maximum speed. For example, a bar code with total width of 3 inches is to be analyzed in a beam length of 6 inches and the SV model being used performs a minimum of 100 scans/analyses per second. Maximum speed of travel is (6 –3)inches /.050 seconds = 60 inches per second in ladder direction.

Setting Ladder Mode Scanning Length Using ScanView Software

The distance and location in the laser beam where a bar code is scanned sometimes must be tuned (programmed) for a particular ladder mode application. In general, the wider the length, the faster the bar codes can travel. In some cases, a narrower scan length is required to mask an adjacent code so only one code at a time is scanned.

Calibration

Calibration is required if any reflectance calculation (e.g., symbol contrast, Rmin, PCS) is used in the application. It is recommended to calibrate the unit in any case during initial setup to ensure the scanning distance and orientation is within device limits. A calibration symbol is supplied with each SV unit as a standard component. Store this symbol in a clean location.

The SV Series can be calibrated using either of the two following procedures:
