Chapter 6: Operation This chapter describes how to operate the NCR 7870. Following is a diagram of the NCR 7870.
6-2 Chapter 6: Operation About Using the Operator Controls Scan Windows The NCR 7870 contains a vertical and horizontal scan window. The vertical scan window is mounted in a Tower Cabinet that rises above the checkstand surface. The horizontal scan window is flush-mounted in the Top Plate. Status Indicators Status Indicator Function Occurs Red (Steady) Indicates unit is in standby mode to read next label. Between scanning. Green Flashes once to indicate a successful bar code read. After scanning.
Chapter 6: Operation 6-3 Motion Detector The Motion Detector is used to detect operator inactivity and power down critical components of the NCR 7870 to reduce wear and extend product operational life Reset / Scale Zero Button This button is used to • re-zero the scale if not performed automatically, • set a tare weight, and • awaken the unit from Sleep Mode. Audible Tone A tone can be programmed to sound to indicate a successful bar code read.
6-4 Chapter 6: Operation About Using the Scanner Proper Label Orientation Because the NCR 7870 uses bi-optic scanning, labels can be read from many angles. Labels can be read from the leading, trailing, bottom, and opposite sides of a package. Bar code labels can be scanned from left-to-right or right-to-left. A good rule of thumb is – if you can’t see the label, the NCR 7870 can read it.
Chapter 6: Operation 6-5 Active Scan Zone The active scan window is shown in the following diagram. The 7870 can read labels presented within the cube. 6.0 in. (15.2 cm) 5.8 in. (14.7 cm) 5.0 (12.7 cm) Scan Zone R0127 Multiple Reads Only one good read is reported if a label is placed within the scan zone and left there. Scanner firmware prevents a second read of the same label if it occurs within a preset time of a good read.
6-6 Chapter 6: Operation Bar Code Quality Many labels in a typical retail environment are unreadable. The 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.
Chapter 6: Operation 6-7 Operating Instructions Power Up The 7870 has no ON/OFF switch. The checkstand should be equipped with a circuit breaker switch during site preparation. The switch should be easily accessible and near the operator. Power up the NCR 7870 on by turning the circuit breaker switch to ON. The NCR 7870 performs diagnostic checks during the power up procedure.
6-8 Chapter 6: Operation Scanning Procedure To use the NCR 7870, the item must pass through the active scan region. Item orientation, motion, and sequential handling are required for proper label reading. Instructions 1. Verify scanner is operable. The red Status Indicator must be lit. 2. Locate label on item. 3. Orient item so label faces away from you. 4. Pass item across the lower scan window. 5. If a good read occurs, the green Status Indicator will flash.
Chapter 6: Operation 6-9 Weighing Procedure The NCR 7870 has a settling time of 0.9 seconds for items five pounds or less and 2 seconds for items over five pounds. The scale will not weigh items exceeding its weight class – 9.995 kg, 13.995 kg, and 30 lbs. The scale can be operated in Mode 1 or Mode 2, depending on your terminal and the type of NCR 7870. In Mode 1, the weight is displayed. In Mode 2, the weight and price are displayed. Instructions 1. Verify display reads SCALE READY 0.
6-10 Chapter 6: Operation Changing the Good Read Tone The volume of the Good Read Tone can be changed while in normal operating mode. This is the only characteristic of the tone that can be changed without being in Programming Mode. Instructions 1. Scan the Volume Adjustment tag and listen to the tone. 2. If the tone is not loud enough, scan the tag again. Repeat if necessary. 3. If the tone is too loud, scan the tag repeatedly until the volume resets to the lowest level. Now scan to the desired level.
Chapter 6: Operation 6-11 Routine Maintenance Routine maintenance is needed at least once a day to keep the NCR 7870 in good operating condition. These parts of the 7870 can be cleaned with a soft cloth, lukewarm water, and mild soap: • Scanner body • Top Plate and Scan Window • Exterior surface of Subplate Assembly • Optics Assembly Window • Horizontal Scan Window • Tower Cabinet If a scan window becomes excessively scratched, replace it.

Chapter 7: Programming General This chapter is intended to acquaint you with programming the NCR 7870. It covers the overall programming process for the NCR 7870. The NCR 7870 Scanner/Scale is fully programmable to meet your system requirements and is already programmed with the factory-set default values when shipped. However, if programming changes are needed, the procedure is very simple. This chapter is divided into five sections.
7-2 Chapter 7: Programming • • • PACESETTER Plus Information covers the use, programming, and interpretation of PACESETTER Plus including • Modes – Inquiry, Real-Time, and Normal • Host Access to Tallies, and • Host Reset of Tallies.
Chapter 7: Programming 7-3 How to Program the NCR 7870 Creating the Program Creating a program consists of three basic steps. Step 1. Writing the Program a) Identify Your Requirements. The first thing you need to do is to determine the requirements of your NCR 7870 installation. This includes information about the communications protocol, the types of bar codes you scan, the use of Good Read tones, and scanner time-outs. b) Complete the Programming Worksheets.
7-4 Chapter 7: Programming Step 3. Save the Program a) Scan the Save and Reset Tag. When you scan the Save and Reset tag, the scanner saves all programming parameters that you entered. This becomes the new scanner program. The scanner goes through initial startup and operates using the new program. b) Save your Programming Worksheets. Be sure to save your programming worksheets that contain the scanner program.
Chapter 7: Programming 7-5 Programming Mode The NCR 7870 Scanner/Scale is programmed in the Programming Mode. You enter this mode by scanning the Programming Mode tag as the first tag scanned immediately after applying power to the NCR 7870. This puts the NCR 7870 in the Base Programming State. As a result, the NCR 7870 produces a long and then a short beep, and the status indicator stays off.
7-6 Chapter 7: Programming Programming Tags After completing the worksheets, enter the information using the special programming tags contained in the NCR 7800, 7870, 7875, 7880, and 7890 Programming Tags book (BST0-2121-74). You do not need a large number of special programming tags, only 5 unique tags and 16 hexadecimal (Hex) character tags. The following identifies each programming tag, its function, and the associated indicators.
Chapter 7: Programming 7-7 Default Function This tag causes most parameters to go to default values. However, scanning this tag does not change a few parameters, including the Communications Protocol. The Default tag must be the first tag scanned after applying power to the NCR 7870. Indication Performs power-up sequence. End Function This tag ends certain input sequences. Since the programming mode determines the end of most sequences, this tag is not used often.
7-8 Chapter 7: Programming Programming Mode Function This tag puts the NCR 7870 in the Base Programming State. It must be the first tag scanned after applying power to the NCR 7870, or after scanning the Default tag. Indication • Short beep as soon as tag is read – Good Read tone • Long and short beep – in Base Programming State • Status indicator – off Save and Reset Function This tag causes the NCR 7870 to save and start using the programming data. It is used in the Base Programming State.
Chapter 7: Programming 7-9 Program Entry Example The following example is a typical program entry procedure. 1. Apply power to the NCR 7870 Scanner/Scale. 2. Scan the Programming Mode tag. 3. Scan the two Hex tags corresponding to the worksheet number. 4. Scan appropriate Hex tags to enter parameters.
7-10 Chapter 7: Programming BASE PROGRAMMING STATE 1 4 Bar Codes - 2 Code 39 0 1 Disable Enable M inim um Characters Allowed Full AS CII 2 -F 0 1 Disable Enable Check Digit Present Disable Enable Transmit Check Digit Disable Enable Allow Single Character Tags 0 0 0 1 1 1 Disable Enable 11722 b) Enter Specific Parameters To enter only one particular parameter in a Specific Programming Mode, scan the two numbered Hex tags that correspond to that specific mode.
Chapter 7: Programming 7-11 parameter options, you have to re-enter the Specific Programming Mode by scanning the two Hex tags again. The following figure shows how to proceed through a Specific Programming Mode where you change only one of the parameters. This figure presents the specific programming mode for Bar Codes 2 program parameters.
7-12 Chapter 7: Programming Programming Tips • Turn the host terminal off or disconnect all interface cables to the NCR 7870 before entering your program. Some host terminals can corrupt your program if they are running and are connected to the NCR 7870 while you are entering the program. • To exit a Specific Programming Mode without entering all the parameters, scan the Abort tag. All parameters entered are retained and the NCR 7870 returns to the Base Programming State.
Chapter 7: Programming 7-13 Program Parameter Descriptions Within the Base Programming State are several Specific Programming Modes. Each of these have specific programming parameters. Communications Protocol The Communications Protocol programming mode selects the protocol that the NCR 7870 Scanner/Scale uses to communicate with the host terminal. Note: The factory sets the Communications Protocol according to the specifications on your order.
7-14 Chapter 7: Programming A scanner or scanner/scale that uses the Datachecker Interface should be programmed using this format. If the protocol information is lost, the scanner/scale defaults to RS-232. It then must be reprogrammed to OCIA NCR Short. Use the Hex 0 tag to enable this protocol. OCIA NCR Long – Hex 1 OCIA Long (Alternate Codes Long Format) is used on the NCR 7852 Alternate Codes Scanner and the NCR 7890 Presentation Scanner.
Chapter 7: Programming 7-15 IBM 468x/9x Port 4B (HHBCR) – Hex 4 tag All models of the NCR 7870 support the IBM 468x/9x format and use the same protocol found on IBM terminals. The scanner uses terminal port 17 and the select address is set to 4B. Use this protocol with the hand held bar code reader. If your unit is a scanner/scale, the IBM address default setting is 6E, but can be programmed to 6A or 6B. The IBM terminal integrated scanner/scale driver normally uses address 6E.
7-16 Chapter 7: Programming Casio 4-Bit, Parallel, Dual Cable – Hex A tag Non-NCR short format is used on some older competitive terminal systems. This format is sometimes called 6-bit ASCII since it can accommodate only 6 data bits per character. It cannot support Code 128 or Code 39 bar code data. This format is normally not used on NCR systems. Use the Hex A tag to enable this protocol.

7-18 Chapter 7: Programming Good Read Tone The Good Read Tone programming mode selects the parameters for sounding a tone each time the NCR 7870 Scanner/Scale successfully reads a bar code. It also controls the volume of the Not-On-File tone. This mode contains five shortcuts: A, B, C, D, and E. After entering this programming mode, you normally go directly to a specific parameter by scanning the appropriate shortcut Hex tag. This eliminates the need to enter all parameters when only one needs changing.
Chapter 7: Programming 7-19 Tone Length (Milliseconds) The Hex C tag permits you to set the length of the Good Read Tone by listening to it. Each time you scan the Hex C tag, the tone length changes from a minimum of 25 milliseconds to a maximum of 250, and then back again. End this mode by scanning the End tag or another valid Hex tag. Tone On/Off The Hex A tag sets the Tone On/Off programming mode, which offers two options, On and Off.
7-20 Chapter 7: Programming Timers The Timers programming mode controls the two NCR 7875 Scanner/Scale timers: Lockout Time and Active Time. Defaults Parameter Default Value Lockout Time 900 milliseconds Restart Lockout Timer Off Active Time 15 seconds Specific Program Parameters Lockout Timer (Milliseconds) The lockout timer prevents the scanner/scale from repeatedly reading the same bar code.
Chapter 7: Programming 7-21 Active Time (Minutes) You can program specific lengths of time that your NCR 7870 Scanner/Scale stays on after the last good read. There are four options in the Active Time parameter: no shut down, shut down after 15 minutes, shut down after 30 minutes, and shut down after 60 minutes. Select these times using the Hex 0 through Hex 3 tags, respectively. The default time is 15 minutes. Selecting no shut down results in the scanner/scale being active all the time.
7-22 Chapter 7: Programming Bar Codes – 1 The Bar Codes 1 programming mode contains programming parameters for UPC/EAN bar codes. Defaults Parameter Default Value UPC/EAN Enable Version D None Extend UPC-A to EAN-13 Disable Extend UPC-E to UPC-A Disable Periodic Codes Disable Periodic Codes Extension 2-Digit & 5-Digit Send Data Data as Decoded Specific Program Parameters UPC/EAN The UPC/EAN parameter controls reading UPC/EAN bar codes.
Chapter 7: Programming 7-23 this parameter. The default is None and scanning a valid Hex tag ends the input for this parameter option. Extend UPC-A to EAN-13 The Extend UPC-A to EAN-13 parameter determines whether to pad the tag data, changing 12-digit UPC tags to 13-Character EAN tags. The program does this by putting a zero (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.
7-24 Chapter 7: Programming extension. The default is 2- and 5-digit extensions and scanning a valid Hex tag causes the program to go to the next parameter option. Send Data The Send Data parameter has three selections: Data As Decoded, Periodical Code Data Only, and CF Hex If Periodical Data Not Decoded. If you scan the Hex 0 tag, the data is sent as decoded, whether or not there are extension digits. If you scan the Hex 1 tag, only valid periodical codes are sent.
Chapter 7: Programming 7-25 Bar Codes – 2 The Bar Codes 2 programming mode contains programming parameters for Code 39.

Chapter 7: Programming 7-33 Label Identifiers The Label Identifiers programming mode selects the parameters for adding label identifiers to communication messages. If used with RS232 or OCIA NCR Long or OCIA NCR Short when reading UPC Version D bar codes, the identifiers go before the bar code data. Label identifiers for the other modes of communication are determined by the firmware and are not programmable.
7-34 Chapter 7: Programming Specific Program Parameters Identifier Type The Identifier Type parameter defines the type and placement of label identifiers. You can select default identifiers that prefix the message data, unique prefix identifiers, or no identifiers. Select the Identifier Type parameter by scanning the appropriate tag (Hex 0, Hex 2, or Hex 3). If you select default identifiers, you do not enter any other parameter in this programming mode. The factory set default is Default Prefix.
Chapter 7: Programming 7-35 2. None -- Scan the Hex 2 tag to select none. No label identifiers are added to the message data. 3. Unique Prefix – - To use a unique prefix, scan the Hex 3. A Unique Identifier is associated with each bar code type. Also, you may use one, two, or no Common Bytes. The figure shows the possible message formats when using a unique prefix. The formats do not show other elements programmed in the other RS-232 programming modes.
7-36 Chapter 7: Programming Note: Refer to the ASCII Code Chart for the Hex Characters; however, values of 20 to 7E are recommended. Do not use the same characters as the Terminator Byte or the message may terminate too soon. Also, a Common Byte cannot be 00. If you are not going to use a Common Byte, you can scan any Hex tag twice except Hex 0 or the Terminator Byte value. The default for Common Byte 1 is 5D (ASCII ]) and the default for Common Byte 2 is 42 (ASCII B).
Chapter 7: Programming Parameter Default Value UPC – A 41 (ASCII A) UPC – D 44 (ASCII D) UPC – E 45 (ASCII E) EAN – 8 46 (ASCII F) EAN – 13 47 (ASCII G) Code 39 31 (ASCII 1) Code 128 33 (ASCII 3) Interleaved 2 of 5 32 (ASCII 2) 7-37 Note: If you use the same characters as in the Terminator Byte, the message may terminate too soon.

7-42 Chapter 7: Programming 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, and Check Digit.
Chapter 7: Programming 7-43 If you enable ACK/NAK, each message sent to the host terminal must be acknowledged before sending the next message. Receiving the message properly causes an ACK to be sent, and if there are any errors, a NAK is sent instead and the scanner/scale sends the message again.
7-44 Chapter 7: Programming Program Example Following is an example of a completed RS-232 Parameters 2 programming worksheet. This example shows the following program selections.
Chapter 7: Programming 7-45 RS-232 Prefix Byte The 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. Following it is the message data. Defaults Parameter Default Value Prefix Byte Disable ASCII Code 02 Specific Program Parameters Prefix Byte The Prefix Byte parameter contains two selections: Disable and Enable.
7-46 Chapter 7: Programming Program Example Following is an example of a completed RS-232 Prefix Byte programming worksheet. This example shows the Prefix Byte enabled, and ASCII Code STX (02 Hex) transmits as the leading character of each message sent to the host terminal.
Chapter 7: Programming 7-47 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. If you included a BCC, it follows the Terminator Byte and includes the Terminator Byte in the calculation. When you apply power to an NCR 7875-2000, the reset function checks the RS-232 Communications Terminator Byte programming.
7-48 Chapter 7: Programming (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. Program Example Following is an example of a completed RS-232 Terminator Byte programming worksheet. This example shows the Terminator Byte enabled and ASCII code CR (0D Hex) transmitted as the Terminator Byte.
Chapter 7: Programming 7-49 RS-232 Communications Options The RS-232 Communications Options parameters control the delay between messages, and the format in which the scanner and host terminal exchange tag data messages. The firmware is programmed to accept one parameter at a time and then leave this programming mode. Therefore, each of the parameters must be programmed separately.
7-50 Chapter 7: Programming With 497-0301951 and higher, the default is 10 milliseconds minimum delay between messages. Messages can be delayed by the following times. • 0 for no delay • 1 for a 10 ms delay • 2 for a 50 ms delay Scanner or Scanner/Scale Format The Scanner or Scanner/Scale Format option permits you to force the data format to either scanner only format or scanner/scale format to accommodate the host terminal.

Chapter 7: Programming 7-53 Scale Parameters The Scale Parameters programming mode controls specific parameters associated with the NCR 7870-2000, 4000, 4500 Scales. You can use it to identify if the NCR 7870 includes a scale, and to define the address if the scale is connected to an IBM terminal. Defaults Parameter Default Value Model Number No Default 9.995 kg/13.
7-54 Chapter 7: Programming protocol sets the scale address to 6E; however, it may need to be changed to 6A or 6B, depending on the IBM configuration in the particular IBM customer retail application. Scan the Hex 5 tag for address 6A, the Hex 6 tag for address 6B, or the Hex 7 tag for address 6E. The IBM terminal integrated scanner/scale driver normally uses address 6E. However, if the scanner works but the scale does not, you should try using the other two scale addresses. 9.995 kg / 13.995 kg The 9.
Chapter 7: Programming 7-55 Miscellaneous Parameters The Miscellaneous Parameters programming mode controls parameters associated with the NCR 7870-2000, 4000, and 4500 Scales that do not fit easily into any of the other categories. The NCR 7870 firmware is programmed to accept one parameter at a time and then leave this programming mode. Therefore, each of the parameters must be programmed separately.
7-56 Chapter 7: Programming scanned or a weight change is registered by the scale. Use the Hex 2 tag to enable the timer. When the 5-Second Weight Timer is disabled, the display will show a weight value until the host terminal sends price information. The price will remain on the display until new weight or price information is sent to the display. Use the Hex 1 tag to disable the timer.
Chapter 7: Programming 7-57 Enable/Disable Voice Messages When you have the voice messages feature on your scanner/scale, the Voice Messages Enabled/Disabled parameter toggles to enable or disable the feature. If voice messages are enabled, you hear them at the appropriate time. If they are disabled, you hear the beep tones instead. The Hex D tag toggles this parameter between enabled and disabled. There is no indication, visual or otherwise, of the state of the enable/disable condition.

7-68 Chapter 7: Programming Special Programming Some of the NCR 7870 features require programming that is somewhat different than the normal programming. Delay Weight Data to IBM Host Terminal A timing condition is possible when the NCR 7870 Scanner/Scale communicates with an IBM host terminal. The condition occurs when the IBM Host is requesting weight data, but the scale is not settled. To prevent the problem, you can enable a scale data delay function that gives the scale more time to settle.
Chapter 7: Programming 7-69 EAN/JAN/UPC Multi-Symbol Scanning Parameters The optional Multi-Symbol programming feature permits you to scan bar code labels containing two or three EAN-13, JAN-13, or UPC-A symbols. Label Construction A multi-symbol label must consist of any combination of two or three EAN-13, JAN-13, or UPC-A symbols, each with different flag digits. Flag digits are the first two digits of the symbol on EAN-13/JAN-13 symbols.
7-70 Chapter 7: Programming Perform the following to program the NCR 7870 for multi-symbol scanning. 1. Disconnect the communications cable from the scanner or the terminal. 2. Apply power to the NCR 7870. 3. To enter the Multi-Symbol program parameters mode, scan the following tags: Programming Mode, Hex 1, Hex 3, and Hex F. 4. Choose an option: Option A: Clear multi-symbol programming by scanning the Hex A tag and the Save and Reset tag.
Chapter 7: Programming 7-71 Result: The scanner sounds the Good Read tone one time to indicate that the scanner accepted the multisymbol label. If the multi-symbol label is already in the scanner's memory, the scanner then beeps twice for a 2symbol label or three times for a 3-symbol label. A long, loud tone (error tone) indicates that the scanner's memory already has the maximum of five multi-symbol label combinations. 5.
7-72 Chapter 7: Programming Early Beep Disable When optional add-on bar codes are programmed, the Early Beep function may need to be disabled. The Early Beep function should not be used on systems, including many IBM host terminals, that sends “scanner disable” commands during the scanning operation.
Chapter 7: Programming 7-73 Good Read Tone Presets The Good Read tone is composed of three elements: volume, frequency (tone), and length. Three different presets, each with a different combination of volume, tone, and tone length settings, are available that permit you to set the Good Read tone by scanning just one sequence of Programming Tags. Preset 0 is the default for this parameter.
7-74 Chapter 7: Programming Good Weigh Tone When Transmitting Data A Good Weigh tone normally sounds when an item is weighed. If the Good Weigh Tone When Transmitting Data option is enabled the Good Weigh tone sounds when the weight data is just starting to be transmitted to the host terminal when using single cable RS-232 communications. The Default tag disables this option. Scan the following programming tags to enable or disable this option.
Chapter 7: Programming 7-75 Terminal Coupon Interface Parameters Certain parameters must be set to permit the unit to transmit coupon data to the host terminal. These are in addition to the general parameters that are required for other scanner/scale functions. Note: Selection of optional add-on bar codes may require additional programming. See Early Beep Disable in the Special Programming section for more information.
