NCR RealScan 7883 Installation and Owner Guide

Programming for USB Connection

The RealScan 7883 Scanner must be properly programmed for USB. Programming and cabling depends on whether the unit is a 7883-1000 or 7883-1200. The 7883-1000 uses the USB Dongle connection to the host terminal while the 7883- 1200 uses a straight through cable. The programming also depends on the type of host terminal being used.

RS-232 Communications

The 7883-1000 communicates with the USB dongle using RS-232. Therefore, the 7883-1000 uses standard RS-232 communications (1 0 5). The RealScan 7883-1200 Scanner outputs USB and uses a cable which connects directly to the terminal. It must be programmed for NCR/232- USB. Other parameters may be set as required by the host terminal. Set the required program parameters by scanning the following sequence of programming tags. These must be the first tags scanned after supplying power to the unit.

7883-1000

1.Default – sets all parameters to standard default values.

2.Programming Mode – puts scanner in base programming state.

3.Hex 1, Hex 0, Hex 5 – sets the required RS-232 programming parameters.

•RS-232 communications protocol

•9600 baud

•Odd parity

•1 stop bit, 7-bit character

4.Change any other parameters as required by the host terminal.

5.Save and Reset – saves the program just entered and resets the scanner.

7883-1200

1.Default – sets all parameters to standard default values.

2.Programming Mode – puts scanner in base programming state.

3.Hex 1, Hex 0, Hex E, Hex 0 – sets the required NCR/232 USB programming parameters.

4.Change any other parameters as required by the host terminal.

5.Save and Reset – saves the program just entered and resets the scanner.

The host terminal software may now be configured to use the communication port assigned by the IO Networks driver in the terminal when the connection is made to USB. Note that it is required to obtain the IO Networks software which is available from the NCR website.

IBM Communications

The host terminal should assign the port and associate the scanner with the application when the USB connection is made. When programming a RealScan 7883 for IBM USB communications, all parameters are set to the standard default values, and the communications protocol is set to IBM USB. This is accomplished by scanning the following sequence of programming tags. These must be the first tags scanned after supplying power to the unit. Note that both the 7883-1000 and 7883-1200 use the same programming sequences. However, the 7883-1000 must use a USB dongle, while the 7883- 1200 uses a USB cable. The jumper in the USB Dongle for 7883-1000 scanners must also be jumpered for IBM (See figure above).

7883-1000 and 7883-1200

1.Default - sets all parameters to standard default values.

2.Programming Mode tag - puts scanner in base programming state.
