Step 2 - Setting Program Parameters and Verifying Host
Connection
Now you need to turn on the NCR RealScan 7883. First load new firmware if needed then make any necessary program
changes. Next scan a few tags to verify that the RealScan 7883 is communicating with the host terminal.
Note: The NCR 7883-1000 firmware cannot be flash. Only the NCR 7883-1200 firmware can be flash.
Turning on the RealScan 7883
The RealScan 7883 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.
Flash Latest Firmware – 7883-1200
Note: Firmware Flashing – Firmware flashing is only available on NCR RealScan scanners that have a Super ASIC
Digital Board. The Super ASIC Digital Board models all have a 2 in the second digit of the model number. For example:
7872-x2xx, 7875-x2xx, 7876-x2xx, 7883-x2xx. Older NCR Scanners have firmware chips that cannot be updated by
flashing. These chips must be replaced to change the firmware.
Although the latest firmware is loaded when the RealScan 7883-1200 is manufactured, newer firmware can be released
after the unit is manufactured but before it is installed. NCR recommends that you check the number of the firmware in the
RealScan 7883-1200 and compare it with the latest firmware availab le on www.NCR.com
To identify the firmware already in the scanner, scan the Diagnostic Mode, Hex 4, & Hex A programming tags. These
must be the first tags scanned after applying power to the unit. The RealScan 7883 gives a voice message containing the
497-xxxxxxx number of its firmware. Compare this number with the number of the firmware file on www.NCR.com
Perform the firmware flashing procedure if the 497-xxxxxxx number of the f irmware file on www.NCR.com
than what is already loaded in the RealScan 7883. Refer to the NCR RealScan 7883 User Guide for firmware flashing
procedures.

Programming the RealScan 7883
Caution: Some host terminals can corrupt the RealScan 7883 program if they are running and are connected to the
RealScan 7883 while you are making program changes. Either turn off the host terminal or disconnect the interface cable
before scanning any programming tags.

NCR RealScan 7883 Installation and Owner Guide
Programming for USB Connection
The RealScan 7883 Scanner must be properly programmed for USB. Programming and cabling depends on whether the
unit is a 7883-1000 or 7883-1200. The 7883-1000 uses the USB Dongle connection to the host terminal while the 78831200 uses a straight through cable. The programming also depends on the type of host terminal being used.
RS-232 Communications
The 7883-1000 communicates with the USB dongle using RS-232. Therefore, the 7883-1000 uses standard RS-232
communications (1 0 5). The RealScan 7883-1200 Scanner outputs USB and uses a cable which connects directly to the
terminal. It must be programmed for NCR/232- USB. 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.
7883-1000
1. Default – sets all parameters to standard default values.
2. Programming Mode – puts scanner in base programming state.
3. Hex 1, Hex 0, Hex 5 – 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.

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 NCR/232 USB programming
parameters.
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 Networks driver in
the terminal when the connection is made to USB. Note that it is required to obtain the IO Networks software which is
available from the NCR website.
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 7883 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. Note that both the 7883-1000
and 7883-1200 use the same programming sequences. However, the 7883-1000 must use a USB dongle, while the 78831200 uses a USB cable. The jumper in the USB Dongle for 7883-1000 scann ers must also be jumpered for IBM (See
figure above).

Scanner
Reduced Space Symbology
Reduced Space Symbology (RSS) permits more data to be recorded in a smaller physical space. This is accomplished by
encoding the data in large symbol characters rather than encoding each data character separately. Also, no quiet zone is
required around the symbols. The RealScan 7883 can read four types of RSS bar codes.
RSS14
RSS-14 is a linear symbology that encodes 14 UCC/EAN digits. This structure provides four segments that can be scanned
and decoded separately, then reconstructed. The total symbol contains 96 modules combined into 46 elements (bars and
spaces).

RSS-14 Stacked
RSS-14 Stacked is a 2-row format. The bottom row is higher than the top row and the two are separated with a separator
pattern. The stacked format is used when not enough linear space is available. A typical use is marking produce in a
grocery store.

RSS Expanded
RSS Expanded is a variable length linear symbology. It can encode 74 numeric or 41 alpha characters. RSS Expanded can
be scanned and decoded in up to 22 segments and then reconstructed.

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 7883 sets the parameters to these values.
Changing the RealScan 7883 program is accomplished by scanning the proper sequence of programming tags, which are
included with the unit. Following are three ma jo r ste ps fo r 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 7883.
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 7883 is communicating with the host terminal.
Following are four good tags that you can use. After verifying that the RealScan 7883 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 overprinted, underprinted,
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.
