Figure 3.2 shows the relationship of the types of memory, and the text that follows summarizes their contents. Figure 3.
PAGE 36
3–6 Overview of Decoder Operations Operating Memory The decoder uses configuration parameters as they exist in operating memory to perform all functions. Initially set to factory defaults, these parameters can be changed using the AUX terminal configuration and ASCII or PCCC host commands. With the exception of specific host communication parameters (See Chapter 12), all parameters take effect immediately when changed① You can use the Default command to reset the operating memory to factory defaults.
PAGE 37
Overview of Decoder Operations 3–7 Storage memory can be thought of as programmable read only memory (PROM). The default parameters are stored as read only (EPROM), while the user changeable portion as retentive EEPROM. for the sake of simplicity and consistency with earlier versions of the DS/DD decoders, we will maintain the conventions that the Save and Recall commands will ask for confirmation to “SAVE CONFIGURATION CHANGES TO EEPROM . . . Y/N?” and “RESTORE CONFIGURATION FROM EEPROM . . .

Configuration: Symbology Configure Symbology Option 1 on the Select Operation menu accesses the Symbology configuration screen. Use this function to select symbologies for decoding and to define the operating parameters to use during decoding. The screen is displayed with the first field highlighted. The default settings are displayed the first time you access this screen. Make changes appropriate for your application.
PAGE 75
6–2 Configuration: Symbology The decoder will auto discriminate between multiple symbologies. For optimum performance, enable only those symbologies and code lengths you intend to use. The following pages define each symbology parameter along with the field type and possible values. The default value is shown in bold letters. Code 39 Field Type Options Select No Yes Enables/disables decoding of Code 39 bar code labels.
PAGE 76
Configuration: Symbology 6–3 Code 39 Check Character Field Type Options Select No Yes Controls whether the decoder is required to compute and verify a code check character for Code 39 bar codes. The code check character ensures that the data is read correctly. The default is No, which means the decoder treats all decoded characters as data. The Code 39 check character is computed as a Modulus 43 sum of all characters value as specified in the AIM specification USS-39.
PAGE 77
6–4 Configuration: Symbology We recommend that you enter specific lengths for Interleaved 2-of-5 labels. Otherwise, a partial scan of symbols could result in a valid shorter read. The decoder will ignore 2 character Interleaved 2-of-5 labels unless you enter a specific length of 2. Interleaved 2-of-5 Check Character Field Type Options Select No Yes Controls whether the decoder is required to compute and verify a code check character for Interleaved 2 of 5 bar codes.
PAGE 78
Configuration: Symbology 6–5 Codabar Field Type Options Select No Yes Enables/disables decoding of Codabar labels. The default of No disables decoding of this symbology. Select Yes to enable decoding. Codabar Specific Lengths Field Type Options Edit Numeric 0 through 64 (0) Sets length checking for Codabar labels. The default is 0, which means the decoder does not check lengths. You can specify up to 8 code lengths (maximum of 64 characters).
PAGE 79
6–6 Configuration: Symbology Code 128 Field Type Options Select No Yes Enables/disables decoding of Code 128 labels. The default of No disables decoding of this symbology. Select Yes to enable decoding. Code 128 Specific Lengths Field Type Options Edit Numeric 0 through 64 (0) Sets length checking for Code 128 labels. The default is 0, which means the decoder does not check lengths. You can specify up to 8 code lengths (maximum of 64 characters).
PAGE 80
Configuration: Symbology 6–7 This check differs from the one above, because instead of looking at the number of transitions in the entire scan, this search only considers the number of transitions contained within the symbol. The decoder rejects the scan if the number of transitions does not correspond to a selected specific length. It attempts to decode all scans if no specific length is specified.

PAGE 84
Configuration: Symbology 6–11 Note: We recommend starting with the default settings for all Pharma-Code parameters except Minimum Number of Bars and Decode Direction, which must be determined by your application. The complex interrelationships among other Pharma-Code options make them best suited for use only by experienced Pharma-Code users in unusual instances when the default values do not provide acceptable results.
PAGE 85
6–12 Configuration: Symbology A typical quiet zone value for the Pharma-Code symbology is 5. Space Tolerance (Pharma-Code Decoders Only) Field Type Options Edit 5 through 40 (15) Ignore Defines the percent difference (in width) between the narrowest and widest space elements of the Pharma-Code symbol.
PAGE 86
Configuration: Symbology 6–13 (Widest Wide Bar – Narrowest Wide Bar ) (Widest Wide Bar + Narrowest Wide Bar ) x 100% = % Bar Tolerance 2 OR (Widest Narrow Bar – Narrowest Narrow Bar) (Widest Narrow Bar + Narrowest Narrow Bar) 2 x 100% = % Bar Tolerance Select a value that is greater than the worst case tolerance to prevent no-reads. Valid bar tolerance values are 5 to 40, or Ignore. The Ignore value allows any amount of tolerance between bars of the same nominal width. The default value is 15 (15%).
PAGE 87
6–14 Configuration: Symbology Decode Direction (Scanner A or B) (Pharma-Code Decoders Only) Field Type Options Select Forward Reverse Sets the direction the decoder uses to decode a scanned label. Direction values are either Forward or Reverse. The default is Forward. The decoder uses the decode direction to determine the least significant bar of a symbol. The examples below show how a Pharma-Code label is decoded depending on the direction. Example 1: The decode direction is set to forward.
PAGE 88
Configuration: Symbology 6–15 The midrange value is half the sum of the widths of the narrowest and widest bar in the symbol. If the setting is midrange, the decoder will not reject symbols based on the wide to narrow bar ratio setting. Instead, all bars greater than or equal to the midrange are wide bars and all bars less than the midrange are narrow bars. Select midrange to prevent the decoder from rejecting a symbol based on the wide to narrow bar ratio.

Chapter 10 Configuration: Host Message Replacement Rules Introduction to Host Message Replacement Rules Function 5 on the Select Operation menu accesses the Host Message Replacement Rules configuration screen. Use this function to modify the message sent to the host. Host message replacement rules may not be required in every application. They are unnecessary when your needs include simple object counting, or collection of raw bar code data.
PAGE 137
10–2 Configuration: Host Message Replacement Rules Symbols vs. Host Message Fields Understanding host message replacement rules and their use requires that you clearly understand the difference between two frequently confused terms. A bar code symbol is the set of bars and spaces from which the scanner gathers data for interpretation by the decoder. A message field is the decoded information sent from the decoder to a host after processing an incoming symbol.

10–4 Configuration: Host Message Replacement Rules A listing of valid metacharacters appears in the table below. Each appears with a general explanation of its function and syntax. More detailed examples of their use appear at the end of this chapter. Note: The host replacement rules interpret a question mark differently than does the match code table. As a metacharacter used with the host replacement rules, a question mark is not interpreted as a single character wild card. See Table 10.B and 10.

If that rule is successful, no other rule specifying field 1 (or All) will be applied. This will continue until a rule satisfies the field, or until all appropriate rules have been applied to field 1. The decoder will continue this process for all fields until each is satisfied, or until all appropriate rules have failed.
PAGE 144
Configuration: Host Message Replacement Rules 10–9 Note: If any rule is enabled for a given source, then all data from that source will pass through the rules. For example, if any rule is enabled for AUX data, then all AUX data will pass through the rules. Therefore, if you construct a rule with Scanner A as the source, and establish no rule for Scanner B, then all data from Scanner A will pass through the rules, while the data from Scanner B will not.
PAGE 145
10–10 Configuration: Host Message Replacement Rules Note: Using a combination of All in the symbol number field and All in the host message field number field within a rule creates a special situation in which the decoder will attempt to match the rule using only those symbols that have not previously satisfied a rule. A rule in which the host message field number is set to All will try to process every symbol to satisfy the search criteria until all of the host fields are satisfied.
PAGE 146
Configuration: Host Message Replacement Rules 10–11 If Scanner A reads the following symbols: AB1 1AB BA1 Then the host message would be AB1AB1AB1. Since the first symbol read satisfies the search criteria, it will continue passing through the rule until all host fields are filled. Changing the symbol number to 2 would lead to a host message of 1AB1AB1AB.
PAGE 147
10–12 Configuration: Host Message Replacement Rules Replace Entire String With Field Type Options Any valid string up to 24 Edit Text characters in length Blank Defines the string or expression that should be sent to the host to replace the string that was matched by the search pattern currently in effect. Whenever the search pattern is satisfied, the replacement pattern defined here will be substituted for the entire string.
PAGE 148
Configuration: Host Message Replacement Rules 10–13 Alignment Field Type Options Select Left Right Determines whether the data in the host message should align to the left or right edge of the field. The default is Right. As described above, fill characters will be applied before the text (pushing the text to the far right) in right justified fields, and after the text (pushing the text to the far left) in left justified fields.
PAGE 149
10–14 Configuration: Host Message Replacement Rules Assembling a Host Message Some applications demand nothing more than a stream of raw bar code data to be of use. However, interpretation and manipulation of that raw data proves useful in many production situations. Host message replacement rules make that interpretation and manipulation possible.

12–4 Configuration: Host Communications ACK Character Field Type Options Edit ASCII 0 through 255 255 = None Defines an Acknowledge (ACK) character for ACK/NAK protocol. The first time the decoder is started, the default is None, which means an ACK character is not defined. From then on, the default is determined at restart by the contents of storage memory.① The ACK character is sent by the host to acknowledge receipt of a message.
PAGE 167
Configuration: Host Communications 12–5 You must define ACK and NAK characters to enable ACK/NAK protocol with the host. ACK/NAK protocol only applies to bar code data sent to the host. It is typically used with the transmission check to provide error detection. You can also use ACK/NAK protocol to provide flow control. Start Scan Character Field Type Options Edit ASCII 0 through 255 255 = None This parameter is used with the stop scan character and only applies when the Decode Mode is set to Host.
PAGE 168
12–6 Configuration: Host Communications Large Buffer Field Type Options Select Yes No Enables or disables use of the 8K byte buffer on the HOST port. The default is No, which disables use of this buffer. The 8K byte buffer allows the decoder to decode and buffer messages to the host. This feature is useful for applications where the host is incapable of handling high burst rates of data from the decoder. If No is selected, the decoder will only buffer one message.
PAGE 169
Configuration: Host Communications 12–7 Transmission Check Field Type Options None LRC Select Checksum – LSB Checksum – MSB Specifies the type of transmission check that is generated at the end of a message sent to the host. The default is None, which means no transmission check is generated. The decoder can generate three types of transmission checks: 1. LRC (Longitudinal Redundancy Check). A byte developed by an exclusive OR of all bytes in a message. 2. Checksum–MSB.

Chapter 16 Chapter Objectives This chapter defines PCCC (Programmable Controller Communications Commands) commands you can send from a host to the decoder using the DH485 interface. These commands allow you to use binary data exchange to configure the decoder, read data from the decoder, and obtain diagnostic information. Protocol Options The PCCC host commands use the Allen-Bradley DH485 link protocol.
PAGE 267
16–2 PCCC Host Commands ATTENTION: When controlling discrete outputs locally using AUX port configuration, suspend host communications to prevent outputs from unintentionally changing state. ! Command Format The general structure and definitions of all commands is shown below. The structure shows the high and low byte of each data word (word= 2 bytes). Data is always transmitted with the low byte of each data word first and then the high byte.
PAGE 268
PCCC Host Commands 16–3 • STS • • • • • Byte 1 specifies the command status which is always 0. TNS Bytes 2 and 3 contain a unique transaction number sequence that links each command to a reply. The TNS is user defined. FNC Code When the CMD byte = 06H (diagnostic command), byte 4 specifies a diagnostic function. For example, FNC = 01 means read diagnostic counters.
PAGE 269
16–4 PCCC Host Commands – 41H – Response to an unprotected read (01H) command – 46H – Response to a diagnostic link (06H) command – 48H – Response to an unprotected write (08H) command If the CMD byte sent in any of the commands is invalid, the STS byte will contain 10H. • STS Byte 1 contains the status of a processed command. The table below lists the STS codes for all commands. Status Response Codes Hex Value 00H 01H 02H 10H Meaning Command successful (no errors). Command complete and successful.
PAGE 270
PCCC Host Commands 16–5 Read Current Bar Code Data Bar code data is stored as a packet in the host buffer of the decoder at address 100H to 3BFH. Each packet contains data from one read operation. The maximum number of bytes in one packet is 704 bytes.
PAGE 271
16–6 PCCC Host Commands Reply - Truncated Data (Host Buffer Contains More Data) High Byte Low Byte MSB 1 LSB STS= 80H 0 CMD Reply = 41H 3 2 TNS 5 4 Data To read the rest of the data in the buffer, send one or more additional read commands. In each command, offset the address appropriately from the previous command. A status of 00H is returned in the reply when the last segment of data from a bar code packet is read. Here is an example.
PAGE 272
PCCC Host Commands 16–7 The following command reads the value of output counter 1: Read Output Counter 1 High Byte Low Byte MSB 1 LSB STS= 00 CMD= 01H 3 0 2 TNS 604H 5 4 00H 7 Size = 4 6 Read Reply High Byte Low Byte MSB 1 LSB STS= 00H 0 CMD Reply = 41H 2 3 TNS 5 7 Counter Data 4 6 You can read more than one counter, however the read operation must specify an address within the valid address range and start on an address boundary.
PAGE 273
16–8 PCCC Host Commands Read Decoder Configuration Data Appendix A lists the address location for each configuration parameter along with the byte size of the data and the default value. To read or examine one or more parameters, send the read command with the appropriate starting address and byte size referenced in Appendix A.
PAGE 274
PCCC Host Commands 16–9 Modify Configuration Data Appendix A lists the address location for each configuration parameter along with the byte size of the data and the default value. To modify a specific parameter, send the write command with the appropriate starting address and the appropriate data referenced in Appendix A.
PAGE 275
16–10 PCCC Host Commands Execute Decoder Function High Byte Low Byte MSB LSB STS= 00H 1 CMD= 08H TNS 3 5 0 2 Command Address = 600H through 639H,640H, 641H 4 Reply High Byte Low Byte MSB LSB 1 STS= 00H 0 CMD Reply = 48H 3 2 TNS If you send a command with an invalid address, the reply returns a status code of 10H (invalid address).
PAGE 276
PCCC Host Commands 16–11 Send Repeat Read Command The Repeat Read command tells the decoder to wait for bar code data. When data is available, the decoder sends it to a specific address in host memory using the unprotected write (08H) command. The host does not have to request data at each poll when a 2760-RB is used (RB polls automatically). The decoder automatically sends bar code data as it is decoded.
PAGE 277
16–12 PCCC Host Commands Cancel Repeat Read Command To terminate the processing of a Repeat Read command, send the Cancel Repeat Read command to the decoder. Cancel Repeat Read Command High Byte Low Byte MSB 1 LSB STS= 00H 3 CMD= 08H 0 TNS 5 2 Cancel Repeat Read Command Address = 641H 4 Display Text Message on AUX Terminal / Enable AUX Terminal Keyboard.A To configure a message for display on the AUX terminal (and/or LCD Display), use the command address 900H or 901H.
PAGE 278
PCCC Host Commands 16–13 Command Replies High Byte 1 Low Byte MSB STS= 00H LSB CMD Reply = 48H 3 0 2 TNS If the AUX port is not set to manual data entry mode (CONFIG jumper is open), the LCD will display the message but not the AUX terminal. The command returns a status of 01H. If the decoder has not processed the previous text message, the command returns a status of 02H indicating the command failed because the display buffer was not available.
PAGE 279
16–14 PCCC Host Commands Example (holds output closed for 10 milliseconds) High Byte Low Byte MSB 1 00H 08H 3 TNS 5 06H 60H 7 00H 0AH LSB 0 2 4 6 Important: A duration of 0000 holds the specified output in the programmed state until it is changed with another host command or via the AUX terminal configuration screens. The condition field on the AUX terminal will display Open or Closed.

Chapter 17 Maintenance and Troubleshooting Chapter Objectives This chapter provides troubleshooting information to assist with problem detection and resolution. It also shows how to replace the I/O module protection fuses. ! Replacing the Battery ATTENTION: Always use caution when replacing fuses or installing accessories within the decoder. The optional lithium backup battery (Catalog Number 1747–BA) will last up to five years.
PAGE 284
17–2 Maintenance and Troubleshooting Replacing Module Fuses The I/O Module Board has fuses for each of the eight modules. The module fuses are located below the module connectors. When replacing fuses, use Replacement Part No. 77104-899-01. Figure 17.
PAGE 285
Maintenance and Troubleshooting Troubleshooting 17–3 This section lists problems that may occur with the decoder and/or connected equipment. Each problem lists possible causes and solutions. Problem: Decoder ”Power On” indicator does not light. Cause: Decoder power switch is in OFF position. Solution: Turn decoder power switch to ON position. Cause: No incoming power. Solution: Verify power source. Cause: Improper connection to power source. Solution: Check connections. Cause: Faulty decoder.
PAGE 286
17–4 Maintenance and Troubleshooting Problem: ”Laser On” indicators on both the decoder and scanner light but the scanner does not emit the laser light. Cause: Mechanical shutter on scanner closed (2755-L4/L5 scanners only). Solution: Open shutter. Cause: Scanner Laser On switch is in OFF position (2755-L7/L9 scanners only). Solution: Turn on switch. Cause: Cable connections between decoder and scanner are loose or defective. Solution: Check cable and connections.
PAGE 287
Maintenance and Troubleshooting 17–5 Solution: Determine the optimum reading angle by using a static bar code label position and checking the Decoder Performance Indicators with the Decode Mode set to Continuous. Fix the scanner at a position that produces a high decoder performance value. After properly positioning the scanner, return the decoder configuration to the correct triggered mode of operation. Cause: Scanner lens is incorrect for the label size.
PAGE 288
17–6 Maintenance and Troubleshooting Solution: Calculate ”scans per label” based on line speed and bar code orientation (picket fence or step ladder). Calculate at least five scans per label at full line speed. If calculation is less than five scans per label, select a higher speed scanner or reduce product line speed. Problem: Output LED indicator does not operate. Cause: Configuration parameters are not set correctly. Solution: Review configuration parameters.
PAGE 289
Maintenance and Troubleshooting 17–7 Problem: Characters do not display or are difficult to read on the LCD Display. Cause: Inadequate contrast. Solution: Improve readability of characters on LCD Display by adjusting LCD Display potentiometer on main logic board. See Chapter 9 for details. Problem: AUX Terminal is set to manual data entry mode, and terminal is displaying duplicate characters.
PAGE 290
17–8 Maintenance and Troubleshooting Solution: Place the AUX Terminal jumper on the logic board in the CONFIG position and make sure the AUX port connector does not have a jumper between pins 15 and 16 (NEMA Type 1) or G and H (NEMA Type 4). Problem: You are unable to perform manual data entry functions at the AUX terminal. Cause: The AUX port is set to configuration mode, not manual data entry mode. Solution: Using one of the AUX Terminal Selectors, switch the AUX port to manual data entry mode.

G–2 Glossary bar code The vertical bars and spaces found in a bar code symbol. bar code density The number of characters which can be represented in a linear inch. bar code label A label that carries a bar code and is suitable to be affixed to an article. bar code symbol A group of vertical bars that represent a character or group of characters whose spacing is determined by a specific set of rules. In most cases, human readable characters are printed below the bars. Also referred to as a field.
PAGE 344
Glossary G–3 character A single groups of bars and spaces representing an individual number, letter or punctuation mark. A graphic shape representing a letter, number or symbol. check digit A digit included within a symbol whose value is based mathematically on other characters included in the symbol. It is used to mathematically check the accuracy of the read. code type See symbology.
PAGE 345
G–4 Glossary E EAN Acronym for European Article Numbering System, the international standard bar code for retail food packages. element 1) A single binary position in a character. 2) Dimensionally the narrowest width in a character, bar or space. encoded area The total linear dimension consisting of all the characters of a code pattern, including start/stop characters and data. G guard bars The bars at the ends and center of a UPC and EAN symbol. They ensure a complete scan of the bar code.
PAGE 346
Glossary G–5 Interleaved 2-of-5 A bar code in which characters are paired together using bars to represent the first character and spaces to represent the second. Inter-Scan Timer A timer that inhibits decoding for a set time interval after a valid read. L LAN Local area network. LSAP An acronym for Link Service Access Point. Used by the DH-485 protocol. Effectively a secondary address for an application service. M match A condition in which decoded data matches data in the match code table.

G–6 Glossary multi-drop link A link that has more than 2 stations (contrasted with a point-to-point link.) multiplexer The incorporation of 2 or more signals into a single wave from which the individual signal can be recovered. N NAK See negative acknowledgement. Negative Acknowledgment An ASCII control character transmitted by a receiver as a negative response to the sender.
PAGE 348
Glossary G–7 output counter A counter that is associated with each output condition. The counter increments by 1 each time the condition occurs. overhead The fixed number of characters required for start, stop and checking in a given symbol. For example, a symbol requiring a start/stop and two check characters contains four characters of overhead. To encode three characters of data, seven characters are required. P PCCC Acronym for Programmable Controller Communications Commands.
PAGE 349
G–8 Glossary scanner A device that optically scans bar code symbols and converts the optical information into digital or analog form and sends it to a decoder. self-checking A bar code or symbol using a checking algorithm which can be applied to each character to guard against undetected errors. Nonself-checked codes may employ a check digit or other redundancy in addition to the data message. space The lighter element of a bar code formed by the background between bars.
PAGE 350
Glossary G–9 symbols per scan A value that indicates the number of bar code symbols expected in a single sweep of the scanning beam. U UPC Acronym for Universal Product Code. The standard bar code type for retail food packaging in the United States. V valid package A scan (or group of scans) that is comprised of valid reads and satisfies the fields per package parameter. valid read A condition that occurs when sufficient valid scans have been decoded to satisfy the capture count.
