Parameter Programming 

The NCR 7893 may need to be configured to meet specific installation needs. The 7893 uses 

special programming tags to modify the various programming parameters (refer to Chapter 5). 

This can be done through the following: 

  scan using special tags 

  sent from a PC with the NCR RealPOS Scanner Tool Suite  

  remotely through the host terminal using the NCR RealPOS Scanner Tool Suite 

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. 

Scan Doctor Diagnostics 

Scan Doctor is the state–of–the–art diagnostic software included in every 7893. It continually 

monitors the unit to identify components that are not functioning correctly. It also provides 

inquiry capability for the host terminal to access specific diagnostic data. Scan Doctor 

diagnoses the 7893 each time power is applied and continues all throughout operation. When a 

problem is found, it notifies the operator through a color-coded LED on the LED Status 

Indicator, and a voice message. It lists the most probable causes first. 

Many Scan Doctor statuses are available from the scanner using the NCR Scanner Tool Suite 

sold separately. 

Power–On Wellness Check 

When power is applied to the 7893, Scan Doctor 

performs a series of diagnostic tests after 

Power–On.  These diagnostic tests include the following:

  RAM (read/write test). 

  Spinner Motor Speed Test. 

  Non-volatile Memory Test.  

  IBM RS-485 TERMPWR Test 

  Laser Diode Test.  

  Program Code (ROM sum-check) Test. 

  FPGA Load Test 

If Scan Doctor finds a problem that hinders operation of the 7893 it disables the unit; otherwise 

the problem is identified and operation continues.
