Note:
The Factory Default for the 7893 is RS-232, 9600 baud, 7-bit data, and 1-stop bit.
Programming Considerations
The 7893 is fully programmable to meet your system requirements.
When you receive your 7893, it is already programmed with default values set at the factory.
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.
