Chapter 1: Introduction

The new NCR RealPOS Presentation Scanner (7893) represents the latest technology in laser
scanning. It features bi-optic electronics, including dual video, flash download technology, and
flash programmability. It is a small, compact unit that weighs about 14 ounces. Being a
presentation scanner, it permits you to present the bar code label to the scanner or pass it by for
bar code reading.

Power for the 7893 is provided either by a powered USB cable or powered RS-232 cable, if
available from the host terminal, or through a +12Vdc wall adapter Power Module. The input
voltage to the NCR 7893 must be +12Vdc.

Using the Scanner

Although the 7893 is very simple to use, it is quite a complex electronic device. It contains a
laser module that generates a low-level laser light. The laser light passes through a series of
mirrors to generate a scan pattern. Reflected light from the bar code is collected and decoded to
determine the bar code data. The scanner then sends the information to the host terminal or
personal computer (PC).

The 7893 produces an omni-directional scan pattern that makes scanning easier. The pattern
looks like several lines are scanning simultaneously, but is actually just a single beam reflected
through several mirrors. It is this pattern that enables the scanner to read bar codes from most
orientations.

This scanner meets the flexible mounting and use requirements for both hands-free and hand­held scanning. The 20 line scan pattern is designed to handle the aspect ratio tags commonly
found in the general merchandise environment, with no orientation required. The large area
covered by the pattern makes presentation scanning easy. The scan pattern is designed such
that all lines expand in length and separation equally through space. The versatility of the scan
pattern results in effective presentation and pass-by scanning. The scan pattern consists of 5
angular sets of 4 scan lines.

There may be times when the merchandise is too large to be presented to the scanner. In these
cases, you can pick up the scanner and move it to the merchandise. Because the scanner is very
light, you can maneuver it easily in these circumstances.

The 7893 does not have an On/Off switch. If you present a label to the scanner when it is idle,
it detects the label and turns on. This occurs with minimal delay in reading the label. After
several minutes of not detecting a valid bar code, the laser (programmable 5-30 minutes) shuts
off.

Chapter 2: Product Information

The 7893 is designed to operate within a wide environmental range. Being a small peripheral
unit, it does not require any special wiring or mounting. Normally, its requirements are within
those of the host terminal or PC.

Physical Considerations

The 7893 is a lightweight unit with design consideration given to handling by store personnel.
Weighing about 14 ounces, it is remarkably easy to pick up when necessary. The 7893 requires
minimal counter space as shown below:

Environmental Considerations

The 7893 operates in all standard-working environments. Temperature and humidity ranges
permitted are greater when the 7893 is in storage or transit. The following table gives the
various environmental requirements.

Power Considerations

An external power supply provides power to the scanner through the interface cable. Due to
power limitations, the 7893 will not be capable of operating solely from 5VDC USB power.
The scanner shall operate with a 12 VDC supply with a peak current draw of less than 1 A.
The power supply input can be 90-264 VAC at 50-60 Hz. A universal power supply comes
with the scanner, depending on the requirements you specify.

Chapter 2: Product Information 2-3

Features and Options

The 7893 is rich in features and options. This section details the features and options that are
available.

Scanning Performance

The NCR 7893 uses laser light to create a pattern of 20 scan lines. As a bar code passes
through these scan lines, the 7893 scanner uses the reflected light to identify the location of
each bar in the bar code.

The following illustration displays the scan pattern. Item scanning maybe done from left to
right or vice versa.

The image below shows the 7893 scan pattern.

Communications Protocol

The 7893 communicates with the host terminal through the following:

 RS-232

 USB (IBM, NCR)

USB Peripheral Port and Main (POS) Communication Port

The 7893 includes a USB Peripheral ports and a Main (POS) Communication Port. This port is
included to permit an easy connection for peripherals and to improve its capabilities by
permitting the devices to be hot–swappable (connecting or disconnecting devices without
restarting the unit).

The USB peripheral port is located at the underside the unit. The purpose of the single USB
peripheral port is to permit the use of a USB thumb drive.

Note: The total combined 5V current for the USB peripheral port must be limited to 500mA.

2-6 Chapter 2: Product Information

Operator Interface

Interface between the operator and the 7893 is very minimal. Messages are sent from the 7893
to the operator through LED status indicator, audio tones, and voice messages.

Voice Messages

If the 7893 has voice enabled, certain mode changes and error conditions are alerted by
synthesized voice messages. These messages give either the changed mode or the error
message with the suggested corrective action. Voice is enabled and disabled in the
Miscellaneous Parameter program.

Note: By default, Voice is ON.

LED Status Indicator

The LED Status Indicator is an intuitive feature of the 7893. It provides visual confirmation for
scanning items using different colors— which is especially ideal for hearing–impaired cashiers
and enables a quieter front end.

The LED Status Indicator is also useful in diagnosing problems with the 7893. Using a color
coded LED, the user may quickly identify problems – thus effectively decreasing downtime
and enhancing productivity.

Motion Detector

The Motion Detector feature prolongs the life of the 7893. This is located inside the scanner
window; it turns off components of the 7893 after an extended period of non–activity. The
default non–active time is fifteen (15) minutes, but can be changed by programming. An item
passing in front of the Motion Detector causes the 7893 to turn on. This movement is the
normal item scanning movement.

Chapter 2: Product Information 2-7

Not–On–File

The 7893 has a Not-On-File feature that locks the scanner and causes the LED Status Indicator
to flash when a bar code is read that is not on file in the store system. This feature prevents the
checker from moving beyond a product not recognized by the system. The Not-On-File feature
is enabled and disabled through programming.

Note: The in-store processor and host terminal must have the host terminal software capable
of supporting Not-On-File determination.

The 7893 is disabled from reading additional tags until the error is cleared. To clear, select the
host terminal’s CLEAR key and manually enter the item and price.

Power Supply

Power Cord (U.S.)

Power Supply

23756

The Power Supply provides the required DC voltage of the NCR 7893 The Power Cord plugs
into an electrical outlet and connects to the Power Supply. A low voltage Power Cable
connects the Power Supply to the 7893. Several power cords are available depending on the
country of installation. The scanner shall operate with a 12 VDC supply with a peak current
draw of less than 1 A. The power supply input can be 90-264 VAC at 50-60 Hz.

In addition, some host terminal interface types can power the 7893 without the use of this
power supply. Please contact your NCR sales representative for details.

2-8 Chapter 2: Product Information

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.

Chapter 2: Product Information 2-9

Ongoing Wellness Check

Scan Doctor runs continuously the moment 7893 is turned on. It constantly performs on-going
diagnostic tests while the unit is running. These diagnostic tests include the following:

 Spinner Motor Speed Test.

 IBM RS-485 TERMPWR Test

 Laser Diode Test.

If a scanner malfunction is discovered during the power-on or on-going diagnostic tests, an
error code will flash on the indicator LED with a unique color sequence. The speech that
accompanies the indicator LED error sequence will suggest corrective action. The following
table lists the supported error codes:

Error Code Problem Suspect Component

0 No power (LED off) Power supply or PCB assembly

2 RAM test failed PCB assembly

5 Motor too slow Motor

6 Bad non-volatile memory (EEPROM) PCB assembly

9 IBM RS485 – no TERMPWR signal IBM host terminal; cable

11 Laser not turned on PCB assembly

12 Program (ROM sum-check) test failed PCB assembly

13 FPGA failed to program PCB assembly

The following table lists the LED color sequences for each error code. The 7893 does not
support all the available color sequences but they are included here for completeness and
future additions:

15 RED RED RED RED RED (PAUSE)

Note: The 7893 will flash sequences of changing colors that match the Scan Advisor (5-LED
light bar) color sequences used on other PXA scanners like the 7884. Except that the 7893
must flash the colors in sequence instead of displaying them all at once.

Service Diagnostics

Scan Doctor includes service diagnostics for the trained service technician. These go beyond
the wellness checks and are accessed through the use of special programming tags. Refer to
Appendix C for more information on the Scanner Service Diagnostics Tests.

Soft Power Down/Power Up

The 7893 can sense periods of scanner inactivity. The scanner's soft power down feature
extends the life of the 7893 by disabling major portions of the unit, which includes the laser
diode, spinner motor, and associated electronics. The length of the inactive period prior to the
soft power down is user-selected and programmed remotely or through tags.

Scanner power up occurs when the 7893 motion detector detects movement. This detector is
located inside the scan window. The 7893 can also be powered up when the checker signs on
the host terminal. This capability assumes appropriate host terminal software.
