    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.

    An important consideration when using data match type commands is the data format. These commands incorporate a “scanner” philosophy rather than a “verifier” philosophy. A scanner philosophy is to report the data encoded in a symbol while a verifier philosophy is to report all symbol characters whether they include data or not.

    • EAN-13 and EAN-8 (including 2 and 5 digit supplemental codes) Operation Modes The SV Series is very flexible, with many programmable features, but basic system operation can be broken down into three modes. Two modes include a sync signal and one mode operates without a sync signal. These modes are programmable via SV Command Language Products’...

  • Page 106: Sync Mode - Stationary Bar Codes

    It is recommended to use serial communications to a host in this mode for the host to determine missing codes. If this mode is used, the SV Series can still detect many print errors because of its partial decode analysis capability. This algorithm can detect a bar code start or stop character and two adjacent characters.

  • Page 113: Chapter A - Sv Series Setup Hints - Scanning Distance And Angle

    The specified scan distance is indicated on a label on the side of each unit. The SV Series' feature of being able to measure a bar code's X dimension makes it convenient for setting up scan distance. In the manufacturing process each SV unit is programmed to accurately measure the X dimension when scanning at the optimum distance.

    2) is set, the SV unit does not have to be moved again. Session Mode Screen Showing the X Dimension Measurement Setting the Proper Scan Angle The SV Series requires a fixed scanning angle for two basic reasons: 1. To maintain proper scanner signal levels in order to effectively decode symbols.
  • Page 115 SV units incorporate proprietary, analog scanners. The scanner gain and offset are adjustable, allowing the units to adapt to practically any material. ScanView software allows easy setup of scanner gain and offset. A quick method of adjusting the scanner using a special command ~Sc is described below. If the "quick method"...

    % reflectance. Calibration affects reflectance calculations only. Calibration does not affect any other calculations or ability to decode a symbol, etc. The scanner gain and offset settings have the major effect on scanning performance. Keeping the scanner signal linear (between the yellow lines as described previously) is very helpful for good decoding, but is CRUCIAL for reflectance measurements.
