    Caution: Read entire section prior to mounting a the RealScan 7802 unit There are four ways the RealScan 7802 can be mounted. All four of these mounting methods utilize the same basic wall mount bracket provided with each unit. The pole mount, stand mount, and plate mount kits are options.

  • Page 12: Mounting To A Wall

    Using an appropriate fastener for the type of wall, attach the bracket securely, slots facing down. Slide the RealScan 7802 housing onto its bracket until it snaps in place – the housing should slide all the way onto the bracket with the rear touching the back of the bracket when it snaps in.

  • Page 13: Mounting To A Stand

    Cut off the excess strap and remove any burrs. 20022 Slide the RealScan 7802 housing on to the bracket until it snaps in – the housing should slide all the way onto the bracket with the rear touching the bracket when it snaps in.

  • Page 14: Wiring The Ethernet Model

    Wiring the Ethernet Model Once the RealScan 7802 unit is mounted in place there are only 2 cables that have to be connected before it can be operated. For aesthetic reasons NCR suggests the AC and network outlets are mounted close to (or in) the ceiling or close to the floor.

  • Page 15: Wiring The Rf Wireless Model

    Plug the other end of the DIN extension cord into the DIN connector on the power supply. Plug the power supply into a grounded electrical outlet – the RealScan 7802 unit starts its boot up sequence. Both 120V and 240VAC power supplies are available.

  • Page 16: Setting Up A Wireless Rf Link

    Load the ESS ID as follows. Create a barcode label with the ESS ID formatted as described above. Power the RealScan 7802 unit and verify the barcode scanner is operational – look at the underside and check the scanner is lit and rotating.

  • Page 17: Adding A Serial Printer

    Check with the factory before attempting to connect a different printer. In OUTPUT mode, serial port 2 is an output only, RS232 data port. The RealScan 7802 receives pre-formatted data and control codes from a printer driver resident on the network host, which it passes, unmodified, through serial port 2 to the printer.

  • Page 18: Wiring Precautions

    In parts of the USA and worldwide where there is a high likelihood of thunderstorm activity it is good practice to install lightning surge protectors on all power and data lines. The RealScan 7802 should be treated like any other network and computer product installed in your facility.

  • Page 19: Chapter 3 - Installing The Software

    Important: The shared RealScan 7802 directory and the realscan.ini file must be on the server and the RealScan 7802 units must be able to find them when they power up. If you want to change the operating modes (or configuration) of a specific unit anytime after the system is up and running, the Unit Configuration program is available in the NCR directory.

This file contains an encrypted copy of the entire non-volatile memory. The only reason to do this is for remote diagnostic purposes and NCR recommends the user only do this under the direct guidance of a technical support engineer.

  • Page 21: Chapter 4 - Network Configuration

    If you are using an MS Windows network, NCR highly recommends Windows NT, 2000, XP, or ME. Windows 95 and 98 can be used as a server for the RealScan 7802, but they are not supported. NT 4 Server and Windows 2000 provide the best performance in terms of response speed, especially if you are using a RF wireless system rather than hardwired Ethernet (10/100baseT).

  • Page 22: Ncr Realscan 7802 Configuration

    The file server can be a Windows system, or an FTP or QFX server on any type of hardware or OS provided it runs TCP/IP. The RealScan 7802 sends the UPC number read from a barcoded item placed under the scanner to the ‘ProductInfo’ server on the host computer which uses this number as a key to find the item in the price and description database(s).
