NCR RealScan 7882 Installation and Owner Guide
Programming for USB Connection
The NCR RealScan 7882 must be properly programmed when using the USB Dongle connection to the host terminal. This programming depends on the type of host terminal being used.
RS-232 Communications
The RealScan 7882 must be programmed for
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
•
•9600 baud
•Odd parity
•1 stop bit,
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 Network driver when the Dongle Adapter Cable was plugged into the USB port.
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 7872 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.
1.Default - sets all parameters to standard default values.
2.Programming Mode tag - puts scanner in base programming state.
3.Hex 1, Hex 0, Hex D - sets the communication protocol to IBM USB.
4.Hex 4, Hex 8, Hex 5 – turns off configuration message processing.
5.Change any other parameters as required by the host terminal.
6.Save and Reset - saves the program just entered and resets the scanner.
