Step 1 - Installing Power Supply  
and Interface Cables  
Connecting the Cables to an NCR RealScan 7882  
The RealScan 7882 can be powered through a wall adapter Power Supply or directly  
from the host terminal. The RealScan 7882 automatically detects which power source is  
being used. In either case, the input voltage to the RealScan 7882 should be +12Vdc.  
The RealScan 7882 current never exceeds 600mA. How the cables are connected to the  
RealScan 7882 depend on the type of interface connection being used.  
Standard Interface Connection  
1. Install the Interface Cable between the RealScan 7882 and the host terminal.  
2. If using the wall adapter Power Supply, locate it in the checkstand at least  
10 inches (25.4 cm) from the RealScan 7882 installed position. Be sure to locate the  
Power Supply where spilled liquids cannot fall onto it.  
3. Fasten a Tie-Wrap around the Power Cable and the Interface Cable to help secure  
the Power Cable.  
Note: If the RealScan 7882 is to receive power from the host terminal, omit steps 2 and  
3.

USB Interface Connection  
Connecting a RealScan 7882 Scanner to a USB port on a host terminal requires two  
cables. One end of the Dongle Adapter Cable connects to the host terminal. The other  
end has an Interface Box that contains a printed circuit board with all the necessary  
circuitry. The host terminal supplies power for this circuitry. An Interface cable  
connects the scanner to this box. A Power Supply connects to the scanner.

Step 2 - Setting Program  
Parameters and Verifying Host  
Connection  
Now you need to turn on the NCR RealScan 7882. After making any necessary  
program changes, scan a few tags to verify that the RealScan 7882 is communicating  
with the host terminal.  
Turning on the RealScan 7882  
The RealScan 7882 does not have an On/ Off switch. Use the circuit breaker switch in  
the checkstand that supplies power to the unit as the On/ Off switch. Put this switch in  
the On position.  
Programming the Communication Parameters  
Caution: Some host terminals can corrupt the RealScan 7882 program if they are  
running and are connected to the RealScan 7882 while you are making program  
changes. Either turn off the host terminal or disconnect the interface cable before  
scanning any programming tags.  
If the Interface Cable is provided as a kit rather than being included with the  
RealScan 7882, you can set the communication parameters by scanning the bar code on  
the label on the cable package. Standard defaults are set for most RS-232 or OCIA  
cables. If the cable is for a specific host terminal, all the necessary parameters required  
for that host terminal are set. The bar code label on the Interface Cable package must  
be the first bar code scanned after applying power to the RealScan 7882.  
If the Interface Cable came with the RealScan 7882, the communication parameters are  
probably correct and you should not need to make any changes to these parameters.  
However, if the RealScan 7882 does not communicate with the host terminal, scan the  
appropriate tag from the following set of communication protocol tags.  
Note: When scanning bar codes on the following pages, be sure to completely cover all  
bar codes except the one you are scanning.

Programming for USB Connection  
The NCR RealScan 7882 must be properly programmed when using the USB Dongle  
connection to the host terminal. This programming depends on the type of host  
terminal being used.  
RS-232 Communications  
The RealScan 7882 must be programmed for RS-232 communications protocol and  
some of the RS-232 parameters must be set to specific values. Other parameters may be  
set as required by the host terminal. Set the required program parameters by scanning  
the following sequence of programming tags. These must be the first tags scanned after  
supplying power to the unit.  
1. Default – sets all parameters to standard default values.  
2. Programming Mode puts scanner in base programming state.  
3. Hex 1, Hex 0, Hex E, Hex 0 – sets the required RS-232 programming parameters.  
RS-232 communications protocol  
9600 baud  
Odd parity  
1 stop bit, 7-bit character  
4. Change any other parameters as required by the host terminal.  
5. Save and Reset – saves the program just entered and resets the scanner.  
The host terminal software may now be configured to use the communication port  
assigned by the IO Network driver when the Dongle Adapter Cable was plugged into  
the USB port.  
IBM Communications  
The host terminal should assign the port and associate the scanner with the application  
when the USB connection is made. When programming a RealScan 7872 for IBM USB  
communications, all parameters are set to the standard default values, and the  
communications protocol is set to IBM USB. This is accomplished by scanning the  
following sequence of programming tags. These must be the first tags scanned after  
supplying power to the unit.  
1. Default - sets all parameters to standard default values.  
2. Programming Mode tag - puts scanner in base programming state.  
3. Hex 1, Hex 0, Hex D - sets the communication protocol to IBM USB.  
4. Hex 4, Hex 8, Hex 5 – turns off configuration message processing.  
5. Change any other parameters as required by the host terminal.  
6. Save and Reset - saves the program just entered and resets the scanner.

NCR RealScan 7882 Installation and Owner Guide  
Making Other Program Changes  
If you still need to make program changes after setting the communication parameters,  
you can enter information directly from the Programming Worksheets. The  
Programming Worksheets, located at the back of this book, identify all the available  
program parameters. Each worksheet relates to a specific programming mode. Most  
programming options have defaults, identified by a heavy box, that are determined at  
the factory. Scanning the Default tag as the first tag after applying power to the  
RealScan 7882 sets the parameters to these values.  
Changing the RealScan 7882 program is accomplished by scanning the proper  
sequence of programming tags. Following are three major steps for making program  
changes.  
1. Enter the Base Programming State by scanning the Programming Mode tag as the  
first tag after applying power to the RealScan 7882.  
2. Select a Programming Worksheet and enter its parameter data by scanning the  
appropriate Hex tags.  
3. Save the program by scanning the Save and Reset tag.  
Note: In most instances the factory determined defaults are the correct parameter  
setting. However, if you do need to make changes, it is recommended that you first set  
all parameters to default values, then make any necessary changes to the appropriate  
parameters.

Scan Sample Tags  
Now you should scan some sample tags to verify that the RealScan 7882 is  
communicating with the host terminal. Following are four good tags that you can use.  
After verifying that the RealScan 7882 is communicating properly with the host  
terminal, continue with the installation.  
Note: For maximum performance, full size labels must be used. The UPC Symbol  
Specification Manual gives the exact size requirements for UPC labels. If the bar height  
is less than specified, more precise presentation to the scanner is required, reducing  
productivity.

Determining Label Quality  
Many labels in a typical retail environment are unreadable. The following illustration  
shows some of the common problems. Vendors and printers regularly supply products  
to the market with bar codes that are over-printed, under-printed, or truncated. Some  
labels have missing margins. Others may be printed around the corners of packages, or  
on media not likely to remain flat when picked up.

The readability of a label depends on variables such as size, placement, color, paper  
type, ink viscosity, and package coatings. The middle of a printing run can yield  
erroneous labels due to the many variants involved. In particular, poor color contrast  
and marginal print quality can make a label hard to read.

When selecting the scan zone, you must also consider how you are mounting the  
scanner, horizontally or vertically. This permits you to optimize the performance for  
your particular installation. Following are four common installations that identify the  
installation type and the scan zone setting. They are given in order of scanning  
efficiency with the first being the most efficient, and the last being the least.

NCR RealScan 7882 Installation and Owner Guide  
Horizontal - Pass-by Scanning  
This installation provides the most efficient way to scan items. It is typically used in  
checkouts where speed is extremely important. In this installation, the operator slides  
items from the input area on the checkstand, across the scanner, and to the output area  
on the checkstand.  
Typical Installation -  
Hyper/Super Market  
Scan Zone - Horizontal  
Installation - Horizontal  
16012  
Vertical - Pass-by Scanning  
This installation is used where the checkstand is not large enough to mount the  
scanner horizontally, but pass-by scanning is needed. In this installation, the operator  
slides items from the input area on the checkstand, past the scanner, and to the output  
area on the checkstand.

Step 4 - Mounting the  
RealScan 7882  
Rubber Feet  
The NCR RealScan 7882 Scanner is supplied with rubber feet that can be attached to  
the sides of the cabinet. This permits the scanner to sit on the checkstand in a vertical  
position without being mounted to the Vertical Mounting Bracket. There are round  
recesses in each side of the cabinet that accept the rubber feet. Remove the paper  
backing from the rubber feet and stick them to the cabinet in the round recesses.  
Plastic Top Plate  
Your installation may use a Plastic Top Plate. Make sure no rubber feet are attached to  
the cabinet.  
1. Properly align the scanner with the Plastic Top Plate.  
2. Fasten the scanner to the Top Plate making sure that all four latches are securely  
latched around the scanner.

1. Put the RealScan 7882 into the hole in the checkstand. Diagrams in NCR  
RealScan 7882 Specifications show the various dimensions of the hole.  
2. Align the RealScan 7882 to the Checkstand. The leading edge of the Top Plate must  
be flush or up to 1/ 16 in. (0.15 cm) below the top of the checkstand. The trailing  
edge of the Top Plate must be flush or up to 1/ 16 in. (0.15 cm) above the top of the  
checkstand.

Checkpoint Cable  
If you are installing a RealScan 7882 Scanner with the Checkpoint feature on a Vertical  
Mounting Bracket, route the Checkpoint Cable along side the Interface Cable.  
Note: If the installation includes the Checkpoint feature, a representative from  
Checkpoint must connect the Checkpoint Cable to the Checkpoint equipment after you  
install the RealScan 7882.  
Cable Clamps  
The RealScan 7882 is supplied with two Cable Clamps (006-0687102). Install these  
clamps under the checkstand as needed to support the cables and keep them out of the  
operators way.

NCR RealScan 7882 Installation and Owner Guide  
Operating the Scanner  
The NCR RealScan 7882 is a fixed position device that is not handled or moved by the  
operator during operation. It is maintained and serviced by trained service personnel  
only. The operator has no access to any laser module components.  
The RealScan 7882 does not have a power switch. However, you turn it on and off by  
using the circuit breaker switch, located in the checkstand, that supplies power to the  
unit. Be sure this switch is in the On position.  
The Red Indicator is on when the RealScan 7882 is ready. When the scanner reads a bar  
code, the Red Indicator turns off and the Green Indicator turns on. Nothing happens if  
the bar code is not read. The correct way to do pass-by scanning is to just slide the item  
past the scan window without lifting the item. With presentation scanning, you lift the  
item, move it straight toward the scan window, then bring the item back away from  
the scanner.

Cleaning the Scanner  
Keeping the scan windows clean helps keep the read rate exceptionally high. During  
normal operation the scan windows get dirty, and if you permit the dirt to accumulate,  
performance degrades to the point where the scanner cannot read bar codes. Use a soft  
cloth to clean the scan windows, using a common, non-abrasive, liquid window  
cleaner. Be sure to spray the cleaner onto the cloth, not directly onto the scanner.

Correcting Scanner Problems  
When the RealScan 7882 is first turned on, several diagnostic tests are run to check the  
status of various components. If a failure occurs, a series of beeps and flashes of the  
Green Status Indicator identify it. The number of beeps (flashes) identifies the problem.  
The problem indication is repeated continuously with a 3-second pause between each  
indication series. Following the first problem indication, the beeps are turned off and  
only the Green Status Indicator flashes to identify the problem.  
If the diagnostics identify a problem, you must have the scanner repaired. Refer to  
Obtaining Technical Assistance at the front of this document. Although several  
conditions can be identified, following are the most common.

Ventilation Requirements  
The RealScan 7882 Scanner/ Scale is designed to operate without an exhaust fan in the  
checkstand; however, there must be adequate convection air flow. The ambient  
temperature inside the checkstand cannot be higher than 104° F (40° C). Also, the  
ambient temperature inside the checkstand cannot be higher than 12.6° F (7° C) above  
the ambient temperature outside the checkstand. For example, if the ambient  
temperature outside the checkstand is 76° F (24.4° C), the ambient temperature inside  
the checkstand cannot be greater than 88.6° F (31.4° C). If the checkstand contains other  
heat producing equipment, you may need to use forced air to keep the temperature  
within the specified range. However, air coming into or leaving the checkstand  
MUST NOT enter or exit past the RealScan 7882 Scanner/ Scale.
