Programming Description 

The 7893 can be remotely programmed from its attached host terminal with no local 

intervention. To achieve this, special host terminal software (NCR RealPOS Scanner Tool 

Suite) must be purchased from NCR. This section describes programming a scanner with 

special bar code tags. 

Programming the 7893 consists of setting programming parameters to match specific needs. 

This is accomplished by scanning a specific sequence of programming tags. The factory sets 

most programming parameters to default values or values originally specified. In most 

installations, few, if any, programming changes need to be made. 

Creating the Program 

Creating a program consists of three basic steps. Details of these steps are given in various 

areas of this programming information. 

Write the Program 

1.  Identify requirements. The first thing is to determine the requirements of the 7893 

installation. This includes information about the communications protocol, the types of bar 

codes to be scanned, the use of good read tones, and scanner time–outs. 

Note:

NCR does not control or specify the NCR scanner configuration required to 

support specific Host Terminal Software unless you are using NCR Host Terminal 

Software.  You should consult with your Host Terminal Software vendor or reseller to 

determine the correct configuration for your NCR scanner. 

2.  Complete the programming worksheets. Using the descriptions contained in this document, 

complete each programming worksheet. Write the entries of the program in the space 

provided. Refer to the “Programming Worksheet” section in Chapter 5 for specific 

information about each parameter. 

Enter the Program 

1.  Enter the programming mode. Scan the Program Mode tag. This must be the first tag 

scanned after supplying power to the  

7893 (or the first tag after scanning the Reset tag). 

2.  Enter the parameters for each specific program. Scan the two Hex tags to select a specific 

program, and then enter all parameter data for it. After all the information has been 

entered, the 7893 returns to programming mode. Repeat this procedure for each specific 

program that needs to be changed. 

Note:

A specific program does not need to be entered if its associated programming is 

already correct. 

Save the Program 

1.  Scan the Save and Reset tag. When the Save and Reset tag is scanned, the scanner saves 

all programming parameters entered. This becomes the new scanner program. The scanner 

goes through initial startup and operates using the new program.
