NCR RealScan 7882 Installation and Owner Guide
09/02 497-0419630 Release F
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 RS-232 communications protocol and
some of the RS-232 parameters must be set to specific values. 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.
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 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.
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.
