    Introduction Chapter 1: The new NCR RealPOS Presentation Scanner (7893) represents the latest technology in laser scanning. It features bi-optic electronics, including dual video, flash download technology, and flash programmability. It is a small, compact unit that weighs about 14 ounces. Being a presentation scanner, it permits you to present the bar code label to the scanner or pass it by for bar code reading.

  • Page 19: Chapter 2: Product Information

    Product Information Chapter 2: The 7893 is designed to operate within a wide environmental range. Being a small peripheral unit, it does not require any special wiring or mounting. Normally, its requirements are within those of the host terminal or PC. Physical Considerations The 7893 is a lightweight unit with design consideration given to handling by store personnel.

  • Page 20: Environmental Considerations

    Chapter 2: Product Information Environmental Considerations The 7893 operates in all standard-working environments. Temperature and humidity ranges permitted are greater when the 7893 is in storage or transit. The following table gives the various environmental requirements. Temperature Temperature Change Humidity Range 10°C to 40°C 5% - 95% Operating Environment...

  • Page 21: Features And Options

    Scanning Performance The NCR 7893 uses laser light to create a pattern of 20 scan lines. As a bar code passes through these scan lines, the 7893 scanner uses the reflected light to identify the location of each bar in the bar code.

  • Page 22: Autodiscrimination

    Chapter 2: Product Information Autodiscrimination The 7893 can decode a variety of barcodes. The ability to differentiate the various barcode types is a standard feature of the 7893. The following is a list of the different barcode types:  UPC–A and UPC–E ...

  • Page 23: Usb Peripheral Port And Main (Pos) Communication Port

    Chapter 2: Product Information USB Peripheral Port and Main (POS) Communication Port The 7893 includes a USB Peripheral ports and a Main (POS) Communication Port. This port is included to permit an easy connection for peripherals and to improve its capabilities by permitting the devices to be hot–swappable (connecting or disconnecting devices without restarting the unit).

  • Page 24: Operator Interface

    Chapter 2: Product Information Operator Interface Interface between the operator and the 7893 is very minimal. Messages are sent from the 7893 to the operator through LED status indicator, audio tones, and voice messages. Voice Messages If the 7893 has voice enabled, certain mode changes and error conditions are alerted by synthesized voice messages.

  • Page 31: Determine Scanner Location

    Chapter 3: Installation Determine Scanner Location When identifying a location for the 7893 scanner, consider the length of the connecting cables. The electrical outlet used for the Power Module can be approximately 74 in. (188 cm) from the host terminal. Depending on the Scanner Module Cable, the scanner can be approximately 9 ft. (274 cm), 6.6 feet (2 meters) or 13.1 feet (4 meters) from the host terminal or PC.

  • Page 32: Installing The 7893

    Chapter 3: Installation Installing the 7893 The 7893 can be connected to the host terminal through a PS/2 keyboard connector. Scan data is input into the PS/2 keyboard port. When connected in this configuration the 7893 cannot receive commands from the host terminal. Note: For the 7893 there is only a single transmit message buffer.

  • Page 33: Usb Keyboard Wedge Communication

    Chapter 3: Installation USB Keyboard Wedge Communication The 7893 can emulate a USB keyboard device by enumerating itself as an HID keyboard. By doing so, it passes barcodes directly to the host’s keyboard driver. This eliminates the need of installing a third party driver since the operating system’s native keyboard input driver will be used.

  • Page 34: Connecting Power

    Chapter 3: Installation Connecting Power 1. Verify that you have the correct Power Module for your electrical outlet. 2. Connect the power connector to the Interface Cable. Depending on the installation, this may be a connector on the cable or a box on the end of the cable. 3.

  • Page 38: Pass-By Scanning

    Chapter 4: Operating the Scanner Pass-by Scanning This type of scanning is the familiar style used at checkout stands, such as in supermarkets. The item is moved across the front of the scanner window with the barcode label oriented to face the scanner window, as shown.
  • Page 39 Chapter 4: Operating the Scanner 2. Position the bar code label completely within the red Laser Scan Pattern as indicated below. Normally the bar code should be three to four inches from the scanner. When the label is read the LED Status Indicator turns green. If enabled, a Good Read Tone also sounds.

  • Page 40: Hand Scanning

    Chapter 4: Operating the Scanner Hand Scanning Occasionally you have merchandise that cannot be picked-up and presented to the scanner. The package may be too heavy or too awkward to hold while trying to position the bar code label. In these circumstances you can pick up the scanner and take it to the merchandise. The 7893 is designed so that you can easily pick the scanner up and hold it.

  • Page 41: Label Rotation

    Chapter 4: Operating the Scanner Label Rotation The 7893 can read labels that are presented in many different positions. You can present labels that are rotated left or right 30 degrees from center, up or down 30 degrees from center, and 360 degrees around center.

  • Page 42: Distance From Scanner

    Chapter 4: Operating the Scanner Distance from Scanner For optimum reading, the distance you must place the label from the 7893 depends on the density and height of the bar code. You can relate this to focusing a camera, where you change the focus setting based on how far away the object is.

  • Page 43: Pacesetter

    Chapter 4: Operating the Scanner PACESETTER NCR has continually improved its PACESETTER technology used on NCR scanner products. Starting out as PACESETTER, it progressed to PACESETTER Plus, and then to PACESETTER III. Vendors and printers regularly supply products with overprinted, underprinted, or truncated bar codes to the market.

  • Page 44: Read Indicators

    Chapter 4: Operating the Scanner PACESETTER III The PACESETTER III feature of the 7893 scanner performs many functions that improve the efficiency of the scanner. It determines what is wrong with a bar code and then fixes it. It also keeps track of problems found.

    However, if you need to make programming changes, the procedure is very simple. First complete a series of programming worksheets then enter the information using special Programming Tags in Appendix A: NCR Scanner Programming Tags or BST0-2121-74. Programming Tags There are 5 unique tags and 16 hexadecimal (Hex) character tags. The following chart identifies each Programming Tag, its function, and the associated indicators.

  • Page 50: Using The Programming Worksheets

    7893 sets the parameters to these values. The scanner also indicates via beeps the Default setting. Enter the program into your scanner by scanning the proper sequence of programming tags found in the NCR Scanner Programming Tags (BST0-2121-74). Following are the three major steps to programming your scanner.
