  • Page 9: Introduction

    INTRODUCTION The RJS SV Series of Scanner/Verifiers is designed to be a universal system component that can analyze linear bar code print quality, check encoded data and detect system failures. In its basic mode of operation, an SV unit acts similar to a normal fixed position scanner by automatically decoding bar codes as they pass through its laser beam.

  • Page 10: Perform Calibration

    + 5 VDC Power Input The SV Series requires + 5 Volts DC, +/- 0.25 Volt. Maximum current consumption is 1 amp. The voltage input must be connected to pin 12 and the ground input should be connected to pin 13 on the I/O connector.

  • Page 11: Edge Sync Mode

    3. Counting ceases upon receipt of the trailing edge of a sync signal. The SV Series determines that at least the number of bar codes expected (programmed) during the sync period have been fully decoded.

  • Page 12: Communication Sync Commands

    Five LED’s are included on the SV Series back panel. Power/Sync LED This LED is illuminated green whenever power is applied to the SV Series. Upon receipt of any sync input (hardware or serial communications) the LED will blink yellow for approximately 100 milliseconds.

  • Page 15: Installation And Setup

    UPC-E w/add-on (5) INSTALLATION AND SETUP Scanner positioning and proper system setup are extremely important for proper SV Series operation. Positioning is important in order to provide accurate analyses. The scan distance must be set accurately to achieve the proper beam focus in order to detect printer flaws and failures such as a worn ribbon (matrix printing), low toner (laser printing), voids (flexo printing), burned pixels (thermal printing), etc.

  • Page 16: Scanner Positioning

    Scanner Positioning Each SV Series has an attached label that indicates the type of scanner, focus distance and recommended scan angle. Use the scan distance and scan angle information to mount the scanner per Figure 2. Figure 2 – Scanner Positioning Notes: 1.

  • Page 17: Bar Code Travel Direction

    Bar Code Travel Speed Considerations A bar code should be present in the beam for at least five scans for 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 max.

  • Page 18: Ladder Direction

    A calibration symbol is supplied with each SV unit as a standard component. Store it in a clean location. The SV Series can be calibrated using either of the two following procedures: Procedure 1: 1.

  • Page 19: Setup Procedure

    Setup Procedure It is highly recommended that RJS ScanVision be used to set up SV Series units. This Windows based software is available free of charge from RJS. The alternative is to use SV Command Language through a host computer.
  • Page 20 *This step is not mandatory, but highly recommended. Scanner focus is dependent on the scan distance. Good focus maximizes the SV Series’s ability to detect printer errors and failures. If this step is omitted, take extra precaution in setting and measuring the scan distance.

  • Page 21: Adjusting Scanner Gain And Offset

    Scanner gain and offset adjustment via commands is available in SV units that have the “A” circled on the label that indicates focus distance. The adjustment capability is useful for adapting the unit to various material types and scanning angles during the setup procedure. Knowledge of RJS ScanVision software is required for best understanding of the following description.

  • Page 22: Technical Specifications

    All Models - 4 bar codes across max. (picket fence direction) Scanner Options Scanners can incorporate options for special optics and/or be focused for special applications. Contact RJS Technical Support and describe your application for assistance. Below are two standard options available.

  • Page 23: Power

    A hardware input is the most common sync source for this mode. Note: When in this sync mode, the sync input is a background application. The SV Series will scan, analyze and report on bar codes as they pass through the beam in this mode, regardless if a sync signal is sensed.

  • Page 24: Sync Mode - Stationary Bar 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. This part of a code is usually present in most print failure situations.

  • Page 38: Mode 00 (~Lv00)

    Custom modes are available – contact RJS Technical Support. After programming the SV unit for the desired port activation parameters, it is recommended to review them. When using ScanVison, this can be done via the Transmit SV Commands Window by sending the ~HT command to review all scanner settings, and sending the ~PT8 command to review all quality parameter failure threshold settings.
  • Page 39 This command allows partial decodes to activate the output ports ~LQ0 This command disables partial decodes to activate output ports. NOTE: In SV firmware versions x238 and lower, ~LQ commands are not implemented and the command ~HQ1 must be used to disable partial decodes from activating ports. In this case the standard data transmission format is modified and ScanVision will not display data characters correctly.

  • Page 40: Mode 02 (~Lv02)

    Mode 02 (~LV02) Mode 02 I/O operation Envelope type sync input on pin 4 Port 3: per sync type. The state of this output must be stable within 12.5 milliseconds after the sync input goes low (trailing edge.) Typical time for stability will be less than 7.5 milliseconds if the sync is received when a bar code or complex graphic is not in the beam.

  • Page 41: Mode 03 (~Lv03)

    ~LDxx This command sets the % decode threshold for a passing condition. If analyzing poorly printed symbols, it is recommended that partial decodes be enabled at the decoder level when this command is enabled. xx = failure threshold. Example ~LD75: if 74 % or less of scans on a code were not fully decoded, this sets a failure for this parameter.
  • Page 42 Sync polarity – programmable (~LP#) Use ~PR0210 for proper port initialization. Port 1 will go active OFF (no current) on an error condition. Port 2 will go active ON (sink current) on an error condition. Port 3 will operate in per analysis pulse mode. Active polarity ON (sink current), approximately 500 millisecond duration.
