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.
