Chapter 1: Introduction

Your new RealScan 7892 Bi-Modal Presentation Scanner represents the latest technology in laser scanning. It is a small, compact unit that weighs about 9.6 ounces. Being a presentation scanner, it permits you to present the bar code label to the scanner. This eliminates the need to move the label past the scan window, reducing the amount of operator activity. The RealScan 7892 also has good pass-by-scanning capability, for those to whom pass-by motion seems more natural.

The RealScan 7892 is available in two models: 7892-0100 and 7892-0200.

The 7892-0100 offers IBM, RS-232, and OCIA communication, and permits you to change among these three programming types. It 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. In either case, the input voltage to the NCR 7892 must be +12Vdc.

The RealScan 7892-0200 offers PC Keyboard Wedge communication only. This model is designed to address the needs of retailers whose point-of-sale application does not accept scan data through a communication port.

1-2 Chapter 1: Introduction

Using Your Scanner

Because your RealScan 7892 is a hands-free presentation type scanner, it is much easier to use in the retail environment. The scanner sits on the counter and you present the bar code label to the scanner.

Although the RealScan 7892 is a presentation scanner, 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.

Single Line Scanning is an optional feature of the RealScan 7892-

0100/0200. This feature permits you to scan a specific bar code in a group of bar codes.

The design of your scanner permits it to sit on a counter top. Your

RealScan 7892 does not have an On/Off switch. To minimize the amount of time the laser is on, the laser is pulsed during idle. 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 1: Introduction 1-3

Laser Scanning

Although the RealScan 7892 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 RealScan 7892 produces an omnidirectional 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.

After reading the information contained in the bar code, the RealScan

7892 sends the information to the host terminal or PC. Interfaces available with the RealScan 7892-0100 for transmitting information are

OCIA NCR Short, OCIA NCR Long, OCIA Non-NCR, RS-232, IBM

468x/469x, IBM-USB or NCR/RS-232 USB using a USB Dongle. The

RealScan 7892-0200 supports Keyboard Wedge, although using different cables. The RealScan 7892 contains all the necessary electronics and firmware for each of these interfaces. When installing the scanner, you can change the interface selection, if needed. Refer to

Chapter 5, Programming and Chapter 6, Troubleshooting.

Chapter 2: Understanding the RealScan 7892

Your RealScan 7892 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 RealScan 7892 is a small, lightweight unit. Weighing 9.6 ounces, it is remarkably easy to pick up when necessary. The RealScan 7892 requires minimal counter space as shown below:

Determine Scanner Location

When identifying a location for your RealScan 7892 scanner, consider the length of the connecting cables. The electrical outlet used for the

Power Module can be approximately 74 in. (188 cm) from the host terminal. Depending on the Scanner Module Cable, the scanner can be approximately 9 ft. (274 cm) from the host terminal or PC. These distances are normally shorter depending on how you route the connecting cables. 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.

Default Setting

Your scanner is shipped in one of eight default modes depending on the cable interface included with the unit. To determine the interface you have and set the default:

•

Scan the Default tag.

•

The scanner gives one long beep and then beeps the same number of times as the protocol options explained above.

Note: Seven of the default and protocol modes are applicable to the

RealScan 7892-0100. Only one mode, Wedge, is applicable to the

RealScan 7892-0200.


Installing the RealScan 7892-0100/0300

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.

Installing the RealScan 7892-0200 (Wedge)

The RealScan 7982-0200 (Wedge) option permits the RealScan 7892 to be connected to the host terminal through a keyboard connector. Scan data is input into the keyboard port. When connected in this configuration the RealScan 7892 cannot receive commands from the host terminal.

Note: Unlike the RealScan 7892-0100 there is only a single transmit message buffer in the RealScan 7892-0200wedge use. The transmission of the data is significantly longer than other communication protocols and can be quite slow if a long intercharacter delay is required.

Note: The Keyboard Wedge cable connects both the scanner and the keyboard to the host terminal through the keyboard port. This cable has two PS/2 connectors. If the Host terminal system has an AT keyboard connector, two adapters are required: an AT to PS/2 and a

PS/2 to AT. These adapters are available locally at most computer stores.

Connecting Power

1.

Verify that you have the correct Power Module for your electrical outlet.

2.

Connect the power connector to the Interface Cable. Depending on the installation, this may be a connector on the cable or a box on the end of the cable.

3.

Plug the Power Module into an electrical outlet. When the RealScan

7892 receives power, the diagnostics checks various hardware components. If the scanner passes the diagnostic tests, it gives a

"ready" indication (four flashes of the Status Indicator). A green flash followed by a red flash is normal and indicates the scanner serial number is stored in the scanner’s EPROM.

Note: If the RealScan 7892 is receiving power from the host terminal, do not connect the Power Module.

Warning: When the host terminal powers the RealScan 7892, do not plug the unit in live. This can cause the Power Supply in the terminal to shut down and may also blow an internal fuse in the terminal. Be sure to turn off the power to the host terminal before connecting the RealScan 7892.


Modifying the Scanner Program

Your RealScan 7892 comes from the factory with all programming parameters set to default values. To change any values that do not match your system requirements, refer to Chapter 5, Programming and

Chapter 7, Program Defaults/Worksheets.

Note: When using USB cables to connect the RealScan 7892 to a host terminal, some of the RS-232 parameters must be set in a specific way.

Refer to the “USB Programming” section in Chapter 5, Programming.

Presentation Scanning

Presentation scanning is much different from that 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.

Chapter 4: Operating Your Scanner 4-3

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.

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 light-weight, you can present the scanner to the merchandise with little effort.

Careful

17269


Label Orientation

Because your 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 bar codes have missing margins. Others may be printed around the corners of the packages or on media that wrinkles when picked up. PACESETTER technology is a standard feature that helps read previously difficult-to- read bar code 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

Some bar code labels are difficult to read in a presentation mode, particularly small labels or labels which are in close proximity to other labels. To solve this problem, the RealScan 7892-0100/0200 has a

Single Line Scanning mode option which permits you to scan a specific bar code in a group of bar codes.

There is a two position switch on the side of the RealScan 7892 to use for Single Line Scanning. Pick up the scanner, press the single line button to the first position and hold it there. This action turns off all but the bottom horizontal line, and turns off the decode as well. After targeting the desired bar code with the single line, press the button to the second position to decode the bar code. Releasing the button back to the first position puts the scanner back in the non-decoding, single line mode, ready to read another bar code when the button is again pressed to the second potion. Releasing the button all the way returns the scanner to the omni-directional mode.

Use the steps below and the illustration that follows to help you with

Single Line Scanning.

1.

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.

2.

Align the bar code to be scanned with the scanner.


3.

Press the button to the second position and the Status Indicator turns from amber to green and the unit beeps, indicating a good read.

Label Rotation

Your RealScan 7892 can read labels that are presented in many different positions. You can present labels that are rotated left or right

30 degrees from center, up or down 30 degrees from center, and 360 degrees around center.

Distance from Scanner

For optimum reading, the distance you must place the label from the

RealScan 7892 depends on the density and height of the bar code. You can relate this to focusing a camera, where you change the focus setting based on how far away the object is.

Depending on the label, reading can range from zero to six inches.

Therefore, when you use your scanner, move the label toward the scanner to a comfortable distance in front of the scan window

(approximately three to four inches) and hold the item momentarily.

Normally the "Good Read" indication occurs within one fourth of a second. If this does not happen, try moving the label a little closer to the scanner.


Read Indicators

Your RealScan 7892 provides two methods of indicating valid reads:

Status Indicator (visual) and Audible Tone. The Status Indicator is always enabled; however, you can disable the audible tone.

Status Indicator

The Status Indicator light is located on the top of the scanner. When the

RealScan 7892 detects bar code data, the laser turns on and the Status

Indicator turns red. When an accurate read of a valid bar code occurs, the Status Indicator turns red until the bar code is removed; it then turns green again.

When using IBM 468x communications, the Status Indicator flashes red

(group of nine flashes repeated at 3-second intervals) when the

RealScan 7892 is offline. This can be caused if the IBM host terminal has not established communications with the RealScan 7892, the host terminal is not turned on, or the interface cable is not connected.

Audible Indicator

You can program a "Good Read" tone that indicates the scanner's ability to accurately read bar codes. This permits you to identify good reads without having to observe the Status Indicator. No tone is generated if the scanner does not detect a valid bar code.


You can enable or disable the Good Read Tone. If the Good Read Tone is enabled, you can also specify its volume and duration. Details for programming the Good Read Tone are in Chapter 5, Programming.

Your 7892 scanner comes with the Good Read Tone enabled.

Indicator Functions

As you move the bar code label into the scan pattern, the scanner tells you if it is able to read the label. The following chart identifies the meaning of each read indicator.

Verify that label appears good.

Straighten label if folded, ensure that bar code is not covered, and try to read again. Be sure bar code is within the scan pattern and close to the scan window. If scanner still cannot read label, key in merchandise information on terminal.


Bar Code Quality

The ability of your RealScan 7892 to read bar code labels depends greatly on the quality of the label. Although the RealScan 7892 can often read bar codes that appear to be bad, it cannot read bar codes that are obstructed, defective, or damaged. If the scanner cannot read the bar code, you must key in the merchandise information at the terminal and go on to the next item. Be sure to tell your supervisor if many bar code labels are defective. The figure below shows some examples of bad bar codes. These are only examples and are not all-inclusive.

Bar Code Torn Poor Color Contrast Red Bar Code On

Red Background

R0026

The readability of a label depends on variables such as sizing, 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.

A label should be considered readable if it meets or exceeds the requirements set forth in the EAN UCC General Specification 1/2000.


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 7892 with RSS can read four types of RSS bar codes. Refer to

Chapter 5, Programming for information about enabling RSS.

RSS-14

RSS-14 is a linear symbology that encodes 14 UCC/EAN digits. This structure provides four segments that can be decoded separately, then reconstructed. The total symbol contains 96 modules combined into 46 elements (bars and spaces).

0100012345678905

19254

RSS-14 Stacked

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

0100991234567899

Preparing for Your Program

Determine the requirements for your program, such as communications protocol, use of good read tone, timeouts, bar code types, label identifiers, RS-232 requirements (if using this protocol) and defaults. You may need to read your system application documentation.

Chapter 5: Programming 5-3

Completing the Worksheets

Programming parameters are contained in the Programming

Worksheets. Before using the worksheets, read the “Using the

Programming Worksheets” section at the beginning of Chapter 7.

You need to know the communication protocol that your host terminal is using so that you can program your RealScan 7892 to the same protocol. If you are unsure of the setting in your scanner, scan the

Default tag. The unit should make one long beep followed by the number of beeps corresponding to the communication protocol. (See

Chapter 3 in this manual.) If this is not the desired default, program the communication protocol first, and then program any additional parameters using the programming tags and worksheets.

The Programming Worksheets identify the default values that are determined at the factory. You only need to use the worksheets that need changing for your particular requirements. Enter your program at the bottom of each worksheet. Be sure to read the sections later in this chapter that relate to the worksheets you are using.


Entering Your Program

Enter your program by performing three basic steps:

1.

Enter the Base Programming state by scanning the Programming

Mode tag first after applying power to the RealScan 7892 scanner.

2.

Select a Programming Worksheet and enter its parameter data by scanning the Hex tags identified in Your Program at the bottom of the Programming Worksheet. Repeat this for each worksheet used if the default is changed.

3.

Save your program by scanning the Save and Reset tag.

Suggestion

If you do not know how your scanner is programmed, you can scan the

Default programming tag to set the scanner to all default values, then make the necessary changes. Scanning the Default tag forces the defaults selected in Worksheet 30.

Note: The Default setting is shown on Worksheet 30 in Chapter 7.


Programming Considerations

Your RealScan 7892 is fully programmable to meet your system requirements.

When you receive your RealScan 7892, it is already programmed with default values set at the factory. However, if you need to make programming changes, the procedure is very simple. First complete a series of programming worksheets, then enter the information using special Programming Tags (BST0-2121-74).

Programming Tags

There are 5 unique tags and 16 hexadecimal (Hex) character tags. The following chart identifies each Programming Tag, its function, and the associated indicators.

Hex 1-Hex F ; Beeps tag value.

Multiples of 4 are short beeps grouped together. Others are longer. Example: Hex D is 3 sets of 4 short beeps followed by 1 longer beep.


Programming Mode

To program your RealScan 7892, it must be in the Programming Mode.

Enter this mode by scanning the Programming Mode tag immediately after applying power to the scanner; it must be the first tag scanned.

This puts the scanner in the Base Programming state. When entering the Base Programming state, the scanner produces a long then short beep; the Status Indicator stays off.

From the Base Programming state, select specific programming modes by scanning the proper two hexadecimal tags. The program parameters that you enter in a specific programming mode are identified on the associated Programming Worksheet.

In each specific programming mode, enter all the information contained on the worksheet by scanning all the proper tags in sequence as shown on the worksheet. In addition, use parameter shortcuts to enter a specific parameter. Program entry goes directly to a specific parameter when you scan the proper Hex tag.

If you do not know how your RealScan 7892 is programmed, you can set it to all defaults, then enter any required changes to match your program. Do this by scanning the Default tag as the first tag after applying power to the scanner. This sets the defaults for the programmed default setting in the scanner. Next, scan the

Programming Mode tag to enter the Programming Mode.

The scanner accepts programming tags only in the Programming

Mode. If you scan a programming tag during normal operation, nothing happens.


Entering Your Program

Entering your program consists of putting the RealScan 7892 in the

Base Programming State, entering the parameter data provided on the

Programming Worksheets, and saving the program. Use the following procedure to enter your program.

1.

Apply power to the RealScan 7892.

2.

Scan the Programming Mode tag.

3.

Scan the two Hex tags corresponding to a worksheet number.

Example: To program the 7892 Timers using Worksheet 12, scan

Hex 1 followed by Hex 2.

4.

Scan the appropriate Hex tags to enter the parameters.

Example: Scan Hex 3 for lockout time of 900 milliseconds; Hex 0 for do not restart lockout timer; and Hex 2 for active time of 15 minutes.

After entering the last parameter, programming returns to the Base

Programming State.


Default Settings

The Default Settings Programming mode sets the scanner’s default

Communications Protocol. This determines the default that is set when you scan the Default Programming tag. The default is indicated by a long beep followed by a series of short beeps to indicate the setting.

For IBM settings, the Default Setting sets the default state for the data format (ASCII or HEX) as well. For Wedge, the UPC-E check digit is also set.

The first seven options (0-6) are applicable to the RealScan 7892-0100.

All model RealScan 7892-0200 scanners are configured as Wedge

(option 7) at the factory. Additional settings for communication options are noted within the selection. Refer to the Default Settings

Worksheet (30) in Chapter 7.

Note: For the Default Settings Programming mode, you must enter 30

B , followed by your selection number (0-7).


Communications Protocol (7892-0100 only)

The Communications Protocol Programming mode selects the protocol that the RealScan 7892-0100 uses to communicate with the host terminal or PC. Refer to the Communications Protocol Worksheet (10) in

Chapter 7.

The Protocol parameter contains seven selections:

•

OCIA NCR Short (0)

•

OCIA NCR Long (1)

•

OCIA Non-NCR (2)

•

IBM 468x Select Address 4A (3)

•

IBM 468x Select Address 4B for 1520BCR (4)

•

RS-232 (5)

•

IBM 468X Select Address 4B for HHBCR (6).


Good Read Tone

The Good Read Tone Programming mode selects the parameters for sounding a tone each time the RealScan 7892 successfully reads a bar code. If you choose to enable the Good Read Tone, you can also program the tone volume and tone length. Refer to the Good Read Tone


Tone On/Off

The Tone On/Off parameter contains two selections: On and Off. The

Hex 0 tag turns off the Good Read Tone and the Hex 1 tag turns on the

Good Read Tone. The default is to turn on the Good Read Tone.

Tone Length

The Tone Length parameter permits you to select the length of the

Good Read Tone. The parameter contains 10 different lengths ranging from 25 milliseconds to 250 milliseconds. Select these times using the

Hex 0 through Hex 9 tags. The default length is 100 milliseconds for the RealScan 7892.

Most people cannot identify short time lengths such as those available for Good Read Tones. To aid in determining your tone length you can increment the tone length by scanning the Hex A tag. Each time you scan the Hex A tag, the tone length increments 25 milliseconds. After reaching 250 milliseconds, the procedures starts over, beginning with

25 milliseconds. You normally end this mode by scanning the END tag. However, you can also end it by scanning another valid Hex tag.

Tone Volume

The tone volume has two settings, Low and High. Scan the Hex 0 tag for low volume and the Hex 1 tag for high volume. The default is High volume.


Parameter Shortcuts

The Good Read Tone Programming mode contains three shortcuts: A,

B, and C. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex

A , Hex B, or Hex C). This eliminates the need to enter all parameters when only one needs changing.


Timers

The Timers Programming mode controls the two RealScan 7892 timers:

Lockout Time and Active Time. Refer to the Timers Worksheet (12) in

Chapter 7.

Lockout Time

Lockout Time prevents the scanner from repeatedly reading the same bar code. After reading a bar code, it must be removed from the scan pattern and the time programmed in Lockout Time must elapse before the scanner can read the same bar code again. The Lockout Time parameter selects the lockout time.

There are 8 different times ranging from 450 milliseconds to 1500 milliseconds. Select these times using the Hex 0 through Hex 7 tags.

The default time is 450 milliseconds.

Restart Lockout Timer

The Restart Lockout Timer parameter controls restarting Lockout Time each time the scanner reads the same bar code. Turning on the Restart

Lockout Timer option has the following effect. After reading a bar code, if the barcode moves out of the scan pattern and then back into the scan pattern before Lockout Time times out, the Lockout Time restarts. The Hex 0 tag turns off this option and the Hex 1 tag turns it on. The default is On.


Active Time

You can program specific lengths of time that your RealScan 7892 stays on after the last good read.

There are six options in the Active Time parameter. Standard values range from 5 minutes to 30 minutes in increments of 5 minutes. The default time is 5 minutes.


The Timers Programming mode has three shortcuts: A, B and C. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex A, Hex

B , and Hex C). This eliminates the need to enter all parameters when only one needs changing.


Bar Codes - 1

The Bar Codes - 1 Programming mode contains programming parameters for Code 128 and UPC/EAN bar codes. Refer to the Bar

Codes - 1 Worksheet (13) in Chapter 7.

UPC/EAN

The UPC/EAN parameter controls reading UPC/EAN bar codes.

Disable reading UPC/EAN bar codes by scanning the Hex 0 tag and enable reading by scanning the Hex 1 tag. The default is to Enable reading.

If you choose to disable reading UPC/EAN bar codes, there are no other entries permitted for this parameter. However, if you enable reading UPC/EAN bar codes, you can program the following parameters.

Extend UPC-A to EAN-13

The Extend UPC-A To EAN-13 parameter option determines whether to pad the tag data, changing 12-digit UPC-E tags to 13-Character EAN tags. The program does this by putting a 0 at the front of the tag data.

Scan the Hex 0 tag to disable this option or the Hex 1 tag to enable it.

The default is Disable. Scanning a valid Hex tag ends the input for this parameter option.

Extend UPC-E to UPC-A

The Extend UPC-E To UPC-A parameter option determines whether to pad the tag data, changing 6-digit, truncated UPC tags to 12-Character

UPC-A tags. Scan the Hex 0 tag to disable this option or the Hex 1 tag to enable it. The default is Disable. Scanning a valid Hex tag ends the input for this parameter option.


Periodical Codes

The Periodical Codes parameter option controls the processing of

Periodical Codes. You disable Periodical Codes by scanning the Hex 0 tag and enable them by scanning the Hex 1 tag. The default is to

Disable Periodical Codes.

If you choose to disable Periodical Codes, there are no other entries allowed for this parameter. Scanning the Hex 0 tag also causes the scanner to go back to the Base Programming state. However, if you enable Periodical Codes, you must program the following parameters.

Periodical Code Extension

The Periodical Code Extension parameter option has three selections:

2-digit extension only; 5-digit extension only; or either 2- or 5-digit extensions. Scan the Hex 0 tag for 2-digit extension only; the Hex 1 tag for 5-digit extension only; or the Hex 2 tag for both 2- and 5-digit extension. The default is 2- and 5-digit extensions. Scanning a valid

Hex tag causes the program to go the next parameter option.

Send Data

The Send Data parameter option has three selections: Data As

Decoded; Periodical Code Data Only; and 7F Hex If Periodical Data

Not Decoded. If you scan a Hex 0 tag, the data is sent as decoded, whether or not there are extension digits. If you scan a Hex 1 tag, only valid periodical codes are sent. If you scan a Hex 2 tag, a hexadecimal

7F is sent as the extension if the scanner could not read a 2- or 5-digit code. The extension is sent after the main tag data. The default is Data

As Decoded. Scanning a valid Hex tag causes the program to go the

Base Programming state.



The Bar Codes - 1 Programming mode contains six shortcuts: A through F. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A through Hex F). This eliminates the need to enter all parameters when only one needs changing.


Bar Codes - 2

The Bar Codes - 2 Programming mode contains programming parameters for Code 39. Refer to the Bar Codes - 2 Worksheet (14) in

Chapter 7.

Code 39

The Code 39 parameter controls reading Code 39 bar codes. Disable reading Code 39 bar codes by scanning the Hex 0 tag and enable reading by scanning the Hex 1 tag. The default is to Disable reading.

If you choose to disable reading Code 39 bar codes, there are no other entries allowed for this parameter. However, if you enable reading

Code 39 bar codes, you can program the following parameters.

Minimum Characters Allowed

The Minimum Characters Allowed parameter option defines how many characters in a bar code must be read the same by two separate scans before determining a valid read has occurred. Set this option to the number of characters in a typical tag. This ensures that the scanner reads typical tags with at least two complete good scans before sending the tag data to the host terminal or PC.

There are fifteen selections for this parameter option. Scan the proper

Hex tag (Hex 2 through Hex F) to enter your selection. The default is 4 characters.

Full ASCII

Code 39 permits full ASCII capability by encoding the additional characters. Disable this function by scanning the Hex 0 tag; scan the

Hex 1 tag to enable the function. Disable is the default.


Check Digit Present

The Check Digit Present parameter option permits you to determine if the bar code must contain a correct check digit to be identified as valid.

If enabled, the bar code is ignored if a check digit is not present. If disabled, a check digit within a bar code is considered part of the data and is transmitted to the host. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to enable it. Disable is the default.

Transmit Check Digit

The Transmit Check Digit parameter option selects whether to send the check digit to the host terminal or PC. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to enable it. Disable is the default.

Allow Single Character Tags

This is a direct entry programming parameter. When enabled, the parameter permits single character Code 39 labels. Disable is the default.


The Bar Codes - 2 Programming mode contains five shortcuts: A through E. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A through Hex F). This eliminates the need to enter all parameters when only one needs changing.


Bar Codes - 3

The Bar Codes - 3 Programming mode contains programming parameters for Interleaved 2 of 5. Refer to the Bar Codes - 3 Worksheet

(15) in Chapter 7.

Interleaved 2 of 5

The Interleaved 2 of 5 parameter controls reading Interleaved 2 of 5 bar codes. Disable reading Interleaved 2 of 5 bar codes by scanning the

Hex 0 tag and enable reading by scanning the Hex 1 tag. The default is to Disable reading.

If you choose to disable reading Interleaved 2 of 5 bar codes, there are no other entries permitted for this parameter. However, if you enable reading Interleaved 2 of 5 bar codes, you can program the following parameters.

Bar Code Length

The Bar Code Length parameter option selects the method for determining if an Interleaved 2 of 5 bar code is a valid length. The

Range Check method identifies a length range by specifying the minimum and maximum number of characters. The Specific Check method identifies two specific bar code lengths by specifying the number of characters in each. With this option, the number of characters in all Interleaved 2 of 5 bar codes must be one of the two numbers. Scan the Hex 0 tag to use the Range Check method, scan the

Hex 1 tag to use the Specific Check method. The default is the Range

Check method.


Value 1 and Value 2

The Value 1 and Value 2 parameter options specify the valid

Interleaved 2 of 5 bar code lengths. Use this option with the Bar Code

Length parameter option described in the previous section. If you select the Range Check method, Value 1 specifies the minimum number of characters in a valid Interleaved 2 of 5 bar code and Value 2 specifies the maximum number of characters. If you select the Specific

Check method, Value 1 contains one specific number of characters and

Value 2 contains another.

Accepted values for Value 1 and Value 2 are 4 to 38 readable characters. The number of readable characters must be an even number; if you specify an odd number, it is rounded up one. Each value is input using two Hex tags. The first can be Hex 0 through Hex 3 and the second Hex 0 through Hex 9. The default for Value 1 is 08. The default for Value 2 is 16.

Check Digit Present

The Check Digit Present parameter determines if the bar code must contain a correct check digit to be identified as valid. If enabled, the bar code is ignored if a check digit is not present. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to enable it. Disable is the default.

Transmit Check Digit

The Transmit Check Digit parameter option selects whether to send the check digit to the host terminal or PC. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to enable it. The default is to Disable sending the check digit.


The Bar Codes - 3 Programming mode contains 4 shortcuts: A through

D. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex

A through Hex D). This eliminates the need to enter all parameters when only one needs changing.

The Bar Codes - 4 Programming mode contains 3 parameter shortcuts.

After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex A,

Hex B , or Hex C). This eliminates the need to enter all parameters when only one needs changing.


Bar Codes - 5

The Bar Codes - 5 Programming mode contains programming parameters for Reduced Space Symbology (RSS) bar codes. Refer to the

Bar Codes - 5 Worksheet (18) in Chapter 7.

Enable RSS

RSS permits more data to be recorded in a smaller space. The RealScan

7892 can be programmed to read RSS tags. When programming the

RSS feature, the programming tags must be the first tags scanned after applying power to the RealScan 7892. Four selections are available:

Disable (Hex 0), Enable RSS 14 (Hex 1), Enable RS14E (expanded) only

(Hex 2), and Enable RSS 14 and RSS 14E (Hex 3). When one of the RSS enabled options is used, additional parameters are required as described below. The default is to Disable reading RSS bar codes.

Scans Required on RSS 14

This parameter sets the number of scans required to read a RSS 14 bar code. Increasing the number of scans can improve reading nominal bar codes. There are four settings: 1 scan, 2 scans, 3 scans, and 4 scans. The default is 1 scan. Set this parameter by scanning the appropriate programming tag, Hex 1 through Hex 4.

Scans Required on RSS 14 E

This parameter sets the number of scans required to read a RSS 14E bar code. Increasing the number of scans can improve reading nominal bar codes. There are four settings: 1 scan, 2 scans, 3 scans, and 4 scans. The default is 1 scan. Set this parameter by scanning the appropriate programming tag, Hex 1 through Hex 4.


USS-128 Emulation Mode

The UCC-128 Emulation Mode refers to the Uniform Code Council

Code 128 Data Formatter Start Code. Two choices are available for this parameter. Scan the Hex 0 programming tag for Normal Mode or the

Hex 1 programming tag to enable UCC-128 Emulation. The default is

Normal Mode.


The Bar Codes - 5 Programming mode contains 4 parameter shortcuts.

After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex A,

Hex B , Hex C, or Hex D). This eliminates the need to enter all parameters when only one needs changing..


Label Identifiers

The Label Identifiers Programming mode selects the parameters for adding label identifiers to RS-232 and OCIA NCR Long communication messages. OCIA NCR Short, OCIA Non NCR, and

IBM 468x communication messages have a fixed format and do not use this programming mode. Refer to the Label Identifiers Worksheet (16) in

Chapter 7.

If you do not change the Unique Identifier, the program uses the last one programmed.

Identifier Type

The Identifier Type parameter defines the type and placement of label identifiers. You can select default identifiers that prefix the message data, default identifiers that suffix the message data, unique prefix identifiers, unique suffix identifiers, or no identifiers.

Select the Identifier Type by scanning the appropriate Hex 0 through

Hex 5 tag. If you select default identifiers, you do not need to enter any other parameter in this programming mode. The factory set default is

Default Prefix.


Default Prefix and Default Suffix

Scan the Hex 0 tag to use the default prefix and the Hex 1 tag to use the default suffix. The default label identifiers vary depending on the type of bar code read. The following chart gives the default identifiers for each bar code type.

AIM Identifiers

Scan the Hex 5 tag to use label identifiers specified by AIM. This format has a close bracket (5DH) as the first character. The second character is unique for the type of tag. The third byte is a modifier byte whose value depends on the tag. AIM uses the Common Byte 1, 5DH, so it can not be changed. Below are the unique bytes for each of the symbologies. Note that UPC-E and UPC-A are sent as EAN-13 tags.

AIM Identifiers are supported starting with Firmware release

497-0424514.

Note: AIM identifiers for UPC/EAN codes require additional changes to the programmed parameters - UPC-E is expanded to UPC-A and

UPC-A is expanded to EAN-13. This is done automatically when selecting AIM as the default, Hex 5. In addition, because all UPC/EAN numbers are treated as a single symbology you cannot select AIM (Hex

4) when selecting a common byte for any of the UPC/EAN tags.

Note: You must scan four tags to go to the next parameter, even if you are using Common Byte 1 only, Common Byte 2 only or no Common

Byte. Any four valid programming tags work.

Bar Code Type

The Bar Code Type parameter selects the bar code type for entering its associated label identifier information. After entering a Bar Code Type, enter the label identifier information as described in the following sections. This procedure repeats until you have changed all the label identifiers for each bar code type desired. Scan the Hex 0 through Hex

6 tag to enter the appropriate Bar Code Type. Since you must select each of these individually for your application, there is no default for this parameter.


Common Byte

The Common Byte parameter selects which common bytes, if any, to add to the bar code data message. Each entry is unique to the previously specified Bar Code Type. Scan the Hex 0 tag for no

Common Bytes, the Hex 1 tag for Common Byte 1, the Hex 2 tag for

Common Byte 2, the Hex 3 tag for both Common Bytes or Hex 4 for

AIM Identifier. The default for this parameter uses Common Byte 2 as a suffix for Code 39, Code 128, and Interleaved 2 of 5 bar code data.

UPC and EAN bar codes do not use Common Bytes. AIM uses

Common Byte 1. AIM Identifiers are supported starting with Firmware release 497-0424514. When selecting AIM, no further entries are required for that label since they are defined by the AIM standard.

Unique Identifier

The Unique Identifier parameter permits you to specify the data sent to the host terminal or PC in the Unique Identifier field. Each entry is unique to the previously specified Bar Code Type. Input this data as two Hex characters. Refer to the ASCII Code Chart in Chapter 7. Values of 20 to 7E are recommended. Using the same characters as the

Terminator Byte causes the message to terminate too soon. The following table gives the default values

The Label Identifiers Programming mode contains 5 shortcuts: A through E. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A through Hex E). This eliminates the need to enter all parameters when only one needs changing.


Additional Bar Code Options

The Additional Bar Code Options Programming mode contains two programming options. One parameter for sending Number System

Character UPC data with all communication protocols except IBM.

From this programming mode you can select whether or not to send the UPC Number System Character. The other permits output of ISBN

EAN-13 tags in ISBN format or EAN-13 format. Refer to the Additional

Bar Code Options Worksheet (19) in Chapter 7.

Note: Only one selector may be made.

UPC Number System Character

This parameter determines whether the RealScan 7892 should include the UPC Number System Character with the UPC data. This applies to all communication protocols except IBM. If Hex 1 is selected, the UPC

Number System Character (the first character on the UPC bar code) is included in the bar code data message.

Hex 0 Disables Number UPC system character.

Hex 1 Enables Number UPC system character (Default).

ISBN Format

An EAN-13 label which starts with 978 implies that the ISBN follows with an EAN-13 check digit. The ISBN consists of 9 digits and a check digit. When enabled, the 978 digits are dropped and the check digit for

ISBN is calculated. Since the ISBN check digit is mod 11, an 'X' is sent when the value is 10. Note that only RS-232 and OCIA Long support this option. OCIA short formats do not allow full ASCII characters and

IBM uses ASCII characters as an option so it is not implemented in these protocols.

Hex 2 EAN-13 format used for ISBN tags (Default).

Hex 3 Enables ISBN format translated from EAN-13 tag.


RS-232 Parameters - 1

The RS-232 Parameters - 1 Programming mode contains four of the parameters required for RS-232 communications. From this programming mode you can select the Baud Rate, Parity, Stop Bits And

Character Length, and Handshake Options. Refer to the RS-232

Parameters - 1 Worksheet (20) in Chapter 7.

Baud Rate

The Baud Rate parameter contains seven selections: 300 Baud, 600

Baud, 1200 Baud, 2400 Baud, 4800 Baud, 9600 Baud, and 19200 Baud.

Scan the appropriate Hex 0 through Hex 6 tag to set the desired Baud rate. The default is 9600 Baud.

Parity

The Parity parameter contains five selections: Odd, Even, Mark, Space, and None. For 7-bit characters, bit 8 is the parity bit; for 8-bit characters, bit 9 is the parity bit. Choosing no parity and 7-bit character length causes the scanner to send two stop bits; the scanner must also receive two stop bits. Scan the appropriate Hex 0 through Hex 4 tag to select the desired Parity. The default is Odd.

Stop Bits And Character Length

The Stop Bits And Character Length parameter contains four selections: 1 Stop Bit and 7-Bit Character length (0), 1 Stop bit and 8-Bit

Character length (1), 2 Stop Bits and 7-Bit Character length (2), and 2

Stop Bits and 8-Bit Character length (3). Choosing no parity and 7-Bit

Character length causes the scanner to send two stop bits; the scanner must also receive two stop bits. If you select 8-Bit Character length and parity, only one stop bit is sent. Scan the appropriate Hex 0 through

Hex 3 tag to set the Stop Bits And Character Length. The default is 1

Stop Bit and 7-Bit Character length.


Handshake

The Handshake parameter contains six selections. When considering these, note that the scanner controls only RTS. It can monitor CTS. The following list identifies each Handshake option.

•

RTS is always low, CTS is ignored (Hex 0 tag).

•

RTS is always high, CTS is ignored (Hex 1 tag).

•

Scanner raises RTS and waits for CTS to go high before transmitting (Hex 2 tag).

•

Scanner raises RTS before transmitting and ignores the state of CTS

(Hex 3 tag).

•

RTS is always low and scanner waits for CTS to go high before transmitting (Hex 4 tag).

•

RTS is always high and scanner waits for CTS to go high before transmitting (Hex 5 tag).

Scan the appropriate Hex 0 through Hex 5 tag to set the Handshake option. The default is RTS High Wait For CTS.


The RS-232 Parameters - 1 Programming mode contains four shortcuts:

A, B, C, and D. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut

Hex tag (Hex A through Hex D). This eliminates the need to enter all parameters when only one needs changing.


RS-232 Parameters - 2

The RS-232 Parameters - 2 Programming mode contains some of the parameters required for RS-232 communications. From this mode you can select BCC Options, Interface Control, Check Digit, and Retransmit

On ACK Timer Expiration. Refer to the RS-232 Parameters - 2


BCC Option

The BCC Option parameters permit you to enable or disable using

BCC. When enabled, the BCC is the last character sent. The BCC is the

Exclusive OR of each byte sent prior to the BCC, except the prefix byte.

Scan the Hex 0 tag to disable the BCC option, or scan the Hex 1 tag to enable it. The default is disabled.

Interface Control

The Interface Control parameter permits you to select how to control the transfer of data between the scanner and the host terminal or PC.

The options are None, enable ACK/NAK, enable XOn/XOff, and enable both ACK/NAK and XOn/XOff.

If you enable ACK/NAK, only tag messages sent to the host terminal or PC must be acknowledged before sending the next tag. NAK is sent and the scanner sends the tag message again. The scanner does not acknowledge messages from the terminal or host.

An XOff message does not permit the transmission of data until the scanner receives an XOn message. An XOff message can be received any time. If the scanner is sending a message when it receives an XOff, data transmission stops after sending the current byte. When the scanner receives an XOn message it sends the remainder of the message. The scanner does not acknowledge XOff and XOn messages with ACK or NAK messages.

Select the interface by scanning the appropriate Hex 0 through Hex 3 tag. The default is None.


Check Digit

The Check Digit parameter permits you to control the transmission of

UPC-A, UPC-E, EAN-8, and EAN-13 check digits. Scan the appropriate

Hex 0 through Hex 3 tags to enable or disable UPC-A, UPC-E, EAN-8, and EAN-13 check digits. The default is Enable UPC-A, EAN-8, and

EAN-13 and Disable UPC-E. This option also affects OCIA Long on later versions of the firmware (497-0301339 and higher).

Retransmit On ACK Timer Expiration

This parameter is used with the Interface Control ACK/NAK parameter to cause the 7892 scanner to automatically resend the message to the host terminal or PC when the ACK Timer has expired.

Scan the Hex 0 tag to disable the Retransmit On ACK Timer Expiration option, or scan the Hex 1 tag to enable it. The default is enabled.


The RS-232 Parameters - 2 Programming mode contains four shortcuts:

A, B, C, and D. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut

Hex tag (Hex A through Hex D). This eliminates the need to enter all parameters when only one needs changing.


RS-232 Prefix Byte

RS-232 Prefix Byte Programming mode controls the use of prefix bytes.

If you use an RS-232 Prefix Byte, it is the leading character in each message sent to the host terminal or PC. Following it is the message data. Refer to the RS-232 Prefix Byte Worksheet (22) in Chapter 7.

Prefix Byte

The Prefix Byte parameter contains two selections: Disable and Enable.

Scan the Hex 0 tag to disable the Prefix Byte, or the Hex 1 tag to enable it. The default is Disable.

ASCII Code

The ASCII Code parameter permits you to specify what ASCII code to use for the Prefix Byte. Enter your selection by scanning the appropriate two Hex tags. Refer to the ASCII Code Chart in Chapter 7.

You can select any value from 01 through 0F. Start Of Text (STX)

ASCII Code 02 Hex is recommended. Scan the two appropriate Hex tags (Hex 0 through Hex 7 for the first character and Hex 0 through

Hex F for the second). The default for this parameter is 02.


The RS-232 Prefix Byte Programming mode contains 2 shortcuts: A and

B. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A or Hex B). This eliminates the need to enter all parameters when only one needs changing.


RS-232 Terminator Byte

The RS-232 Terminator Byte Programming mode controls the use of terminator bytes. If you use an RS-232 Terminator Byte, it goes at the end of the message sent to the host terminal or PC. If you included a

BCC (RS-232 Parameters - 2 Programming mode), it follows the

Terminator Byte and includes the Terminator Byte in the calculation.

Refer to the RS-232 Terminator Byte Worksheet (23) in Chapter 7.

Terminator Byte

The Terminator Byte parameter contains two selections: Disable and

Enable. Scan the Hex 0 tag to disable the Terminator Byte, or the Hex 1 tag to enable it. The default is Enable.

ASCII Code

The ASCII Code parameter permits you to specify what ASCII code to use for the Terminator Byte. Enter your selection by scanning the appropriate two Hex tags. Refer to the ASCII Code Chart in Chapter 7.

You can select any value from 01 through 0F. The End Text (ETX)

ASCII Code 03 Hex or a Carriage Return (CR) 0D Hex is recommended. Scan the two appropriate Hex tags (Hex 0 through

Hex 7 for the first character and Hex 0 through Hex F for the second).

The default for this parameter is 03.

Second Terminator Byte

This program is direct entry only. This option sends scan data with two terminating bytes:

2 3 C 0 Disable (Default)

2 3 C 1 Enable (must enter ASCII Code parameter as noted above)



The RS-232 Terminator Byte Programming mode contains 3 shortcuts:

A, B and C. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A, Hex B, or Hex C). This eliminates the need to enter all parameters when only one needs changing.


Communications Options

The Communications Options Programming mode controls parameters associated with the RealScan 7892 communications. Options in this mode were added in July of 1993 and January of 1994. If your scanner does not respond to any of these options, they are not in your firmware.

For these options the scanner firmware is programmed to accept only one parameter at a time. It then returns to the base programming state.

Therefore, each of the parameters must be programmed separately.

Refer to the Communications Options Worksheet (24) in Chapter 7.

Send IBM Tags in Hex or ASCII

Some IBM systems send/receive the IBM tags as hex data, and others use ASCII. ASCII data format is often required with the Hand Held Bar

Code Reader (option 10-6 under Communications Protocol). Scan the

Hex 0 tag to send/receive the tags as hex data. Scan the Hex 1 tag to send/receive them as ASCII data. Sending hex data is the default (for the IBM data protocol #3 and for ASCII protocol #4 and #6).

Maintain or Drop OCIA Message Data/Retries on IBM

Some systems want the scanner to hold OCIA tag data until the terminal clocks it, and some systems prefer to have the scanner just drop the data after one to two seconds. If you scan the Hex 4 tag, the

RealScan 7892 holds or maintains the OCIA tag data. If you scan the

Hex 5 tag, the scanner drops the data after one to two seconds. Holding the tag data is the Default.


When you use an IBM terminal and the scanner detects a bad message from the terminal, this parameter controls how the original message gets transmitted again. If you scan the Hex 4 tag, the scanner transmits the original message forever. If you scan the Hex 5 tag, the scanner only retransmits the original message three times. After failing three times, the scanner reinitiates communications and attempts to transmit the tag data again. (Do not use this selection unless advised to do so by

NCR to solve a problem.) Retrying forever is the Default.

RS-232 Mode: Normal or Eavesdrop

The Eavesdrop Mode is a method of physical connection between the

RealScan 7892 and its host (PC) that places a “dumb CRT” between the host and the scanner. This mode permits the RealScan 7892 to accept input from the “dumb CRT” and then transmit the data on its own transmit line to the host. (If the scanner receives data while it is transmitting, the data is lost.) When using this mode, a special

Eavesdrop Mode cable is required. Data transmitted by the terminal is sent to the RealScan 7892 and re-transmitted to the host. Data from the host is sent to the "dumb CRT". The scanner sends its data to the host.

In Normal Mode, the RealScan 7892 transmits and receives directly with the host. If you scan the Hex 6 tag, the scanner receives and transmits to match the Normal RS-232 connection. If you scan the Hex

7 tag, the scanner receives and transmits to match the Eavesdrop connection. Normal RS-232 connection is the Default.

RS-232 Delay

You can select three different delays between messages when using RS-

232 communications. If you do not want any delay, scan the Hex 8 tag.

Scan the Hex 9 tag for a 10-millisecond delay or the Hex A tag for a 50millisecond delay. Selecting the proper delay can ensure that all tag data is received by the host. When using Handshaking, at least a 10 ms delay should be used to ensure that the host has sufficient time to exercise refusal of the next message. The default is 10 ms for the

RealScan 7892.


OCIA NCR Short Soft Reset

This program parameter permits the RealScan 7892 to receive a soft reset command in OCIA Short format without parity information from the terminal. The default is set to receive an OCIA Short soft reset command with parity. A soft reset causes the scanner to do a scanner enable.


Single Line Scanning (option)

Single Line Scanning (RealScan 7892-0100/0200) may be disabled.

Under Single Line Scanning two additional options are programmable.

The Default with Single Line Scanning is Enable. Refer to the Single

Line Options Worksheet (25) in Chapter 7.

Switch Activation

The scanner switch has two positions. The default (Hex 1) sets the switch to work as a double position switch; the first position shows the scan line and the second position permits decoding of the data. The other option (Hex 0) sets the switch as a single position switch, where the first position both shows the scan line and reads the bar code.

Line Width

You may set the scanner for either Narrow Line or Wide Line. Wide

Line is the normal line width, and is set with Hex 1. Narrow Line reduces the line width approximately 30%, and is set with Hex 0. Wide

Line is the default.


Parameter Version Number

You can keep track of the current version of the parameter settings by assigning a Parameter Version Number. The version number is a two byte entry, which means four Hex tags must be scanned. Each hex tag value can range from 0 - F. Refer to the Parameter Version Number



Wedge Options

The Wedge Options Programming mode controls parameters associated with the RealScan 7892-0200/0300. Refer to the Wedge

Options Worksheet (28) in Chapter 7.

Country Code

The two options for Country Code are United States and International.

Scan the Hex 0 tag for United States. Scan Hex 1 for International.

United States is the default.

Caps Lock

This option permits you to select the state of the Caps Lock Key when using Code 128 or Code 39 labels. The scanner assumes a fixed state for the Caps Lock Key; it does not track the state of the Caps Lock Key.

The Shift Key is used by the scanner to output the appropriate upper or lower case character depending on the data in the bar code. Scan the

Hex 0 tag for Caps Lock OFF or the Hex 1 tag for Caps Lock ON. Caps

Lock ON is the default.

Number Lock and Keypad

Normally the number keys above the letters on a keyboard are used to output numbers. However, some applications may use the numeric keypad. When the numeric keypad is used, the state of the Num Lock

Key may be ON or OFF.

Scan the Hex 0 tag for Keypad not Used; the Hex 1 tag for Keypad

Used Num Lock OFF; or the Hex 2 tag for Keypad Used Num Lock

ON.


Intercharacter Delay

Intercharacter Delay permits additional delay between the transmission of each keycode character. Most terminals today can use the Default value of every 4 milliseconds. The times are based on motor speed (not on a clock) and are approximate. Scan the appropriate Hex tag (Hex 0 – Hex 4) for the desired delay.

Intercharacter Delay options are Every 4 ms, Every 12 ms, Every 24 ms,

Every 48 ms, or Every 96 ms.


The Wedge Options Programming mode contains 4 shortcuts: A, B, C and D. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag

(Hex A, Hex B, Hex C or Hex D). This eliminates the need to enter all parameters when only one needs changing.


Scanner Programming Summary

The following is a summary of how to program your RealScan 7892.

Use this summary along with the information contained in this chapter.

Creating the Program

1.

Identify your requirements

Determine the requirements of your program. This includes information about the communication protocol, information about the types of bar codes you scan, the use of good read tones, and scanner timeouts.

2.

Complete the Programming Worksheets

Using the descriptions contained in this chapter, complete each

Programming Worksheet. Write your program in the space provided.

Entering the Program

1.

Prepare the RealScan 7892

Apply power to the RealScan 7892, then scan the Programming

Mode tag. This puts the scanner in the Base Programming state.

2.

Determine the Default

Decide on the Default if it is different from the way the unit was received. Make all other parameter selections after selecting the

Default.

3.

Select the specific Programming Worksheet

Scan the two Hex tags for a specific programming mode, then enter all the parameter data for it. After entering all the parameter information, the scanner returns to the Base Programming state.

Note: To exit a specific programming mode without entering all the parameters, scan the Abort tag. All parameters entered are saved and the scanner returns to the Base Programming state.


4.

Select the next specific Programming Worksheet

Repeat step 3 for each Programming Mode. You do not need to enter a specific programming mode if its associated programming does not need to be changed.

Saving the Program

1.

Scan the Save and Reset tag

When you scan the Save and Reset Tag, the scanner saves all the programming parameters you entered. This becomes the new scanner program. The scanner goes through initial start-up and operates using the new program.

Note: To exit the Base Programming state without saving any parameters, scan the Abort tag. The scanner goes through initial start-up and operates using the old program.

2.

Save your programming worksheets

Be sure to save your Programming Worksheets that contain the scanner program. It is much easier to reenter the program, or change some of it, if you have a written record of the existing program. The worksheets are also used after repair or replacement of the unit.


USB Programming

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.

Note: Some host terminals can corrupt your program if they are running and are connected to the RealScan 7892 while you are entering the program. Turn the host terminal off or disconnect all interface cables to the RealScan 7892 before entering your program.

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. This option is currrently only available in firmware 497-0426893.

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.

Chapter 6: Troubleshooting

Your RealScan 7892 RealScan uses tones and the Status Indicator light to identify problems. It performs diagnostics that check various scanner functions at different times. Diagnostic checks are made each time power is applied to the scanner and while the scanner is operating.

If your RealScan 7892 does not work properly, you might be able to determine the problem and correct it without having to send the scanner in for repair. Use the following steps to help isolate the problem.

1.

Identify exactly what the scanner is doing, or not doing. Pay particular attention to the Status Indicator light and the tone.

2.

Verify that you are operating the scanner according to the procedures described in Chapter 4, Operating Your Scanner.

3.

Refer to the following table to see if your scanner condition is identified. If your specific problem is not identified, follow your normal repair procedures. This may include sending your RealScan

7892 in for repair.

Repairing Your RealScan 7892

If you have determined that you cannot correct a problem with your scanner, you can return it to the factory for repair or make arrangements for repair at your location. Contact your NCR

Representative for information about the cost and any specific instructions.

When returning your RealScan 7892 to the factory, pack it in the shipping carton that you saved when you received your scanner. The illustration on the top flap of the box shows how to pack your scanner in the box. Send only the RealScan 7892. Do not include the Power

Module, Scanner Module Cable, and Interface Cable. Also, include a description of the problem; be as specific and complete as possible. Be sure to include your name and address.

If you did not save your shipping carton, use another box suitable for shipping. Be sure to pack your scanner with enough packing material to prevent damage during shipment.

Chapter 6: Troubleshooting 6-5

Fuse (old cable only)

Your RealScan 7892 does not contain a fuse inside the cabinet.

However, there is a fuse in the connector box on the end of the

Interface Cable. The green light on the connector box should be on if the Power Module is plugged into the proper electrical outlet and is connected to the scanner. If the light is off, you may need to replace the fuse inside the connector box. The fuse has the following values.

•

1.5 Amp

Chapter 7: Program Defaults/Worksheets 7-3

Using the Programming Worksheets

The Programming Worksheets provide a convenient method of defining your RealScan 7892 program before loading it into the scanner. Each worksheet relates to a specific programming mode. Enter 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 7892 scanner.

2.

Select a Programming Worksheet and enter its parameter data by scanning the Hex tags identified in Your Program at the bottom of the 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.

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, it is recommended that you first set all the parameters to default values by scanning the Default tag, then make any necessary changes to the appropriate parameters.
