Scanner Location When identifying a location for your NCR RealScan 7892, you must consider the length of the connecting cables. The electrical outlet used for the Power Module can be approximately 74 inches (188 centimeters) from the host terminal. Depending on which Scanner Module Cable you have, the scanner can be approximately 6.6 feet (2 meters) or 13.1 feet (4 meters) from the host terminal or PC. However, these distances are normally shorter depending on how you route the connecting cables. You also want to be sure that the Scanner Module Cable is long enough to permit the scanner to be picked up when required for large packages.
Like any electronic device, your RealScan 7892 should not be located in direct sunlight. Temperatures above 104 degrees Fahrenheit (40 degrees Celsius) can occur when sunlight falls on objects through windows or on an outdoor checkstand.

Installing Your NCR RealScan 7892-0100
The RealScan 7892 can be connected to the host terminal through a standard interface connection or through a USB connection. Power for the RealScan 7892 is provided through a wall adapter Power Module or directly from the host terminal.
Standard Interface Connection In most configurations the Scanner Cable connects the RealScan 7892 to your host terminal. Refer to the terminal documentation for information about connecting this cable. Some terminals require a trained technician to perform this function. If a Power Module is required, it connects to a connector on the Scanner Cable.
Some less common configurations require two cables: a Scanner Cable and an Interface Cable. If a Power Module is required for this configuration, it connects to the box on the end of the Scanner Cable.
Note: The Power Module is not used if the RealScan 7892 receives power from the host terminal.

Programming the RealScan 7892
The RealScan 7892 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 7892 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. Programming Mode tag – puts scanner in base programming state. 2. Hex 3, Hex 0, Hex B, Hex 5 – sets the required RS-232 programming parameters.
• RS-232 communications protocol • 9600 baud • Odd parity • 1 stop bit, 7-bit character
3. Save and Reset – saves the program just entered and resets the RealScan 7892.
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 7892 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. Programming Mode tag – puts scanner in base programming state. 2. Hex 3, Hex 0, Hex E, Hex 1 – sets all parameters to standard default values and
sets the communication protocol to IBM USB. 3. Change any other parameters as required by the host terminal. 4. Save and Reset – saves the program just entered and resets the RealScan 7892.

Operating Your Scanner
The RealScan 7892 is designed for both presentation scanning and pass-by scanning. Pass-by scanning is often used at checkout stands, such as in grocery stores. In the checkout stand environment, normally large quantities of items must be scanned in a short amount time. Therefore, you pass the items over the scanner, moving them from one side of the checkstand to another. The scanner reads the label while the items are moving by.
With presentation scanning, you simply present the label to the scanner and then remove it. Do not move the label past the scanner, but to the scanner. Presentation scanning is particularly useful in a retail environment where the number of items associated with each transaction is normally small. There are three simple steps to presentation scanning.
1. Move the bar code label to the scanner as shown.
17682
Scan Window
2. Position the bar code label completely within the red Laser Scan Pattern as indicated below. Normally the bar code should be three to four inches from the scanner. When the label is read the Status Indicator turns green, then returns to red. If enabled, a Good Read Tone also sounds.

3. Move the bar code label away from the scanner as shown. The scanner is now ready to read another bar code label. To read another bar code, simply perform these three steps again.
17685
Pick-Up Scanning Occasionally you have merchandise that cannot be picked-up and presented to the scanner. The package may be too heavy or too awkward to hold while trying to position the bar code label. In these circumstances you can pick up the scanner and take it to the merchandise. The RealScan 7892 is designed so that you can easily pick the scanner up and hold it. Being lightweight, you can present the scanner to the merchandise with little effort.

Careful

497-0003071 Release E 04/03 13 of 38
Label Orientation
Because your NCR RealScan 7892 produces a dense, omnidirectional scan pattern, labels can be read from many different angles.
Scan Pattern Location In order for the scanner to read a label, the center 90% of one scan line must cross the bar code. To successfully read Code 39 and Interleaved 2 of 5 labels, the scan line must cross the entire label, not missing any of the bars or spaces. UPC and Code 128 labels can be read by piecing together two reads of slightly more than half of each side of the bar code. Therefore, these labels are much easier to read and do not require as much accuracy when presenting the label to the scanner.
Because of the large scan pattern, you do not have to be very precise when you position the label. However, the concentration of scan lines is greater in the center of the scan pattern. Because of this, fewer rejects occur if you try to position the merchandise so that the label is presented toward the center of the scan pattern.
PACESETTER Vendors and printers occasionally supply products to the market with bar codes overprinted, underprinted or truncated. Some labels have missing margins. Others may be printed around the corners of the packages or on media that wrinkles when picked up. PACESETTER is a standard feature that addresses the problem of unreadable labels.
PACESETTER Plus trailer provides for symbol quality data being applied at the end of UPC and EAN bar codes. This capability can be either programmed using the programming tags or on command when using RS-232 communication program.

Single Line Scanning Single Line Scanning is a feature of the NCR RealScan 7892-0100/0200; it is not available with the 7892-0300. This feature permits you to scan a specific bar code in a group of bar codes. The RealScan 7892-0100/0200 has a two-position switch located on the side of the unit.
• Press the switch to the first position. The Status Indicator LED turns from red to amber and a single red line is visible across the bar code.
• Align the bar code to be scanned with the scanner. • Press the switch to the second position and the Status Indicator turns from amber
to green and the unit beeps, indicating a good read.

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 character separately. Also, no quiet space is required around the symbols. The RealScan 7892 with RSS can read two types of RSS bar codes, both of which can be stacked: RSS-14, RSS-14 Stacked, RSS Expanded, and RSS Expanded Stacked. Refer to the NCR 7892 BiModal Presentation Scanner User Guide (B005-00000-1182) for details about each of these bar codes.
Taking Care of Your Scanner Although your RealScan 7892 is rugged, remember to treat it carefully. Keeping the Scan Window clean helps keep the read rate exceptionally high. Follow these simple instructions to keep your scanner clean and well maintained.
• Clean the scanner body with a soft cloth dampened by warm water and a mild soap.
• When the Scan Window is dirty, clean it with a cloth dampened with warm water.
Your RealScan 7892 is designed to provide you with long, trouble-free service. However, it is up to you to care for your scanner. The following list identifies things you should consider in taking care of you scanner.
• Handle the scanner with care. • Keep the Scan Window clean. • Replace the Scan Window if excessively scratched. • Do not pick up the scanner by the cable. • Do not submerge the scanner or let it get wet.

Using the Programming Worksheets The Programming Worksheets that follow provide a convenient method of defining your RealScan 7892 program before loading it into the scanner. Each worksheet relates to a specific programming mode. Circle your selections and changes on the Worksheets. Save this information for future use should it be necessary to re-enter this program.
Most of the programming options have defaults that are determined at the factory. A bolded box around an entry selection specifies it as the default value. Scanning the Default tag as the first tag after applying power to the RealScan 7892 sets the parameters to these values. The scanner also indicates via beeps the Default setting.
Enter the program into your scanner by scanning the proper sequence of programming tags found in the NCR Scanner Programming Tags book (BST0-2121-74). Following are the three major steps to programming your scanner.
1. Enter the Base Programming State by scanning the Programming Mode tag as the first tag after applying power to your RealScan 7892.
2. Select a Programming Worksheet and enter its parameter data by scanning the Hex tags identified for that Programming Worksheet. Repeat this for each worksheet.
3. Save your program by scanning the Save and Reset Tag.
Caution: Some host terminals can corrupt your program if they are running and are connected to the RealScan 7892 while you are entering a program. Either turn off the host terminal or disconnect the interface cable from the host terminal before entering your program.

04/03 497-0003071 Release E 20 of 38
Note: In most instances the factory determined defaults are the correct parameter settings. Normally you only need to change a few of these parameters and do not need to enter all the Programming Worksheets. When programming your scanner, first set all the parameters to default values by scanning the Default tag, then make any necessary changes to the appropriate parameters. If you need to change the Default protocol, program that first.
