  • Page 84: Pass-through

    VB24 6.2 PASS-THROUGH Pass-through mode allows two or more devices to be connected to a single external serial interface. Each VB24 transmits the messages received by the Auxiliary interface onto the Main interface. All messages will be passed through this chain to the host. When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.

    VB24 8 MAINTENANCE 8.1 CLEANING Clean the laser beam output window periodically for continued correct operation of the reader. Dust, dirt, etc. on the window may alter the reading performance. Repeat the operation frequently in particularly dirty environments. Use soft material and alcohol to clean the window and avoid any abrasive substances. Clean the window of the VB24 when the scanner is turned off or, at least, when the laser beam is deactivated.

If using rail power, does rail have power? If using CBX100, does it have power (check switch and LED)? Measure voltage either at pin 13 and pin 25 (for 25-pin connector) or at spring clamp Vdc and GND (for CBX).

    This organization (a service of the Food and Drug Administration) is responsible for the safety regulations governing acceptable limitations on electronic radiation from laser devices. Pepperl+Fuchs GmbH devices are in compliance with the CDRH regulations. Code Positioning Variation in code placement that affects the ability of a scanner to read a code. The terms Pitch, Skew, and Tilt deal with the angular variations of code positioning in the X, Y and Z axes.
  • Page 108 VB24 Decoder As part of a barcode reading system, the electronic package which receives the signals from the scanner, performs the algorithm to interpret the signals into meaningful data and provides the interface to other devices. The decoder is normally integrated into the scanner. European Article Number System.
  • Page 109 VB24 Picket-Fence Orientation When the barcode’s bars are positioned vertically on the product, causing them to appear as a picket fence. The first bar will enter the scan window first. See par. 7.2.2. Pitch Rotation of a code pattern about the X-axis. The normal distance between center line or adjacent characters.
  • Page 110 VB24 Signal An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of which represent changes in information. Skew Rotation about the Y-axis. Rotational deviation from correct horizontal and vertical orientation; may apply to single character, line or entire encoded item. See pars. 0 and 3.3. Step-Ladder Orientation When the barcode’s bars are positioned horizontally on the product, causing them to appear as a ladder.
