Installation Instructions
When installing a RealScan 7882, it is recommended that you firs t mount t he Power
Supply and run all the cables. After connecting the unit to the host terminal, make any
necessary programming changes and scan some good tags to verify that the scanner is
communicating with the host terminal. After verifying that everything is working
correctly, mount the unit in the checkstand. If the RealScan 7882 does not work
properly, refer to the Correcting Sca nner P ro blems sectio n in this d o c ument.
The following flowchart shows the sequence of installation steps. Detailed descriptions
of each step follow.

Step 1 - Installing Power Supply
and Interface Cables
Connecting the Cab les 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 t he cables are c onnected t o t he
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 Po wer Supply, lo c a t e it in the c hec ks t and at lea st
10 inches (25.4 cm) from the RealScan 7882 installed position. Be sure to locate the
Power Supply where spilled liq uid s c annot fa ll ont o it .
3. Fasten a Tie-Wrap around the Power Cable and t he Interf ace C able t o help sec ur e
the Power Cable.
Note: If the RealScan 7882 is to receive power from the host terminal, omit steps 2 and
3.

Step 2 - Setting Program
Parameters and Verifying Host
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 pr o gr a mm ing tags.
Connection
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 ca ble is f or a s pecif ic hos t t er minal, all t he nece ss ary parameters required
for that host terminal are s et . The bar c od e label on the Interf ac e Cable pac kage 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 ar e
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 exc ept t he one you are sc anning.

Programming for USB Connection
The NCR RealScan 7882 must be properly programmed when using the USB Dongle
connect io n t o t he ho s t terminal. This pro gr a m mi ng d e pends on the t ype o f ho s t
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 progr amming 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 softwar e may now be configur ed to use t he c ommunicat ion port
assigned by the IO Network driv er when the Dongle Ad apt er C able 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 pr ot o c o l is s et t o IB M U SB. This is ac c omplis hed by s c anning 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.

Making Other Program Changes
If you still need to make pr o gr am c hanges a ft er s et t ing the c ommunic at io n par amet er s ,
you can enter information directly from the Programming Worksheets. The
Programming Worksheets , lo c at e d at t he bac k of t his boo k, id entif y all t he av ailable
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 fact o ry. Sca nni ng t he 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 s t eps for making program
changes.
1. Enter t he B a s e Programm ing S t a t e 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 pr o gram by sca nning 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.

Many labels in a typical ret a il envir o nment are unreadable. T he follo wing illust r at io n

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.
