Chapter 2 Communications Communications by Embedded Menu In addition to ESP-MP, Microscan’s scanners have an embedded menu that can be accessed from the terminal window within ESP or a separate terminal program. See for instructions on using the embedded menus. For older, slower computers, the embedded menus might be a quicker method of communicating with your scanner.
Host Port Parameters Host Port Parameters 2–Communications Baud Rate, Host Port Definition: The rate at which the scanner and host transfer data back and forth. Usage: Can be used to transfer data faster or to match host port settings. Serial Cmd: Default: 9600 Options: 0 = 600 1 = 1200 2 = 2400 3 = 4800 4 = 9600 5 = 19.2 K 6 = 38.4 K 7 = 57.
Chapter 2 Communications RS422 Status Enables RS422. When RS422 is enabled, RS232 is enabled. Usage: Only changed if necessary to match host setting.
Auxiliary Port Auxiliary Port 2–Communications As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical with those of the auxiliary device. Definition: An auxiliary port connects the scanner to a remote display or to other scanners that can display or transfer data.
Chapter 2 Communications Transparent Mode Definition: • Auxiliary port data to the host is always sent with a preamble and a postamble. Scanner • If the scanner is in a polled mode to the host, auxiliary port data will still pass through. • is the only command accepted by the scanner from the auxiliary port. All other commands will pass through to the host. Data initiated from the Scanner • Transmission to the auxiliary port occurs immediately upon a good read.
Auxiliary Port Half Duplex Mode Definition: In Half Duplex mode all auxiliary port data and bar code data is sent directly to the host. Bar code data is displayed on the auxiliary port screen at the same time the data is sent to the host. Data initiated from the Auxiliary Port 2–Communications • Auxiliary port data to the host is ignored if the scanner is in a polled mode. Host • Auxiliary port data or scanned data is sent to the host whenever it is received. • Auxiliary port data is not echoed.
Chapter 2 Communications Full Duplex Mode Definition: In Full Duplex mode all auxiliary port data and bar code data is sent directly to the host. Bar code data is not displayed on the auxiliary port screen. Data initiated from the Auxiliary Port Host Aux Port • Auxiliary port data or scanned data is sent to the host whenever it is received. • Auxiliary port data is not echoed. Scanner • Auxiliary port data to the host is always sent without a preamble or a postamble.
Auxiliary Port Daisy Chain Mode 2–Communications Note: See also “Daisy Chain Autoconfigure” on page 2-27. Definition: In a daisy chain application, scanners are connected in tandem or “daisy chain” and decoded data is relayed from one scanner to another on up to the host. A master scanner has its host port linked to the host computer and its auxiliary port linked to the host port of the first “slave” scanner in the chain.
Chapter 2 Communications Conditions: The conditions for a daisy chain application are as follows: 1. The master scanner’s trigger must be Serial or External; the slave scanners’ triggers are configured for Serial. 2. All scanners are enabled to Daisy Chain mode. Host Slave Master 4. Each slave scanner in the daisy chain must be set to send its data no less than 20 mS before its preceding scanner. 5. All but the master scanner must have Postamble enabled and set to CR (^M) only. 6.
Auxiliary Port Aux Port Communications Parameters As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical with those of the auxiliary device.Baud 2–Communications Rate, Aux Port Definition: The rate at which the scanner and host transfer data back and forth. Usage: Can be used to transfer data faster or match an auxiliary device.
Chapter 2 Communications Stop Bits, Aux Port Allows the user to select the last one or two bits in each character to indicate the end of the character. Usage: Only changed if necessary to match host setting.
2–Communications Auxiliary Port 2-14 MS-820 Industrial Bar Code Scanner User’s Manual
Chapter Protocol 3 Chapter Contents Protocols are the rules by which devices pass data back and forth. This section includes the basic options available for data communication, including multidrop and user-defined options and output data formats. Note: The characters NULL <> and , can only be entered through embedded menus, not through ESP or serial commands. MS-820 Industrial Bar Code Scanner User’s Manual 3-1 3–Protocol Protocol.......................................................................
Protocol by ESP Click this button to bring up the Protocol menu 3–Protocol To change a setting, double-click the setting and use your curser to scroll through the options.
Chapter 3 Protocol Protocol by Embedded Menu For information on accessing the embedded menus, see “Embedded Menus” on page A-19.
Protocol Protocol Protocols define the sequence and format in which information is transferred between the scanner and the host, or in the case of Multidrop, between scanners and a concentrator. Usage: In general, the point-to-point protocols will work well in most applications. They require no address and must use RS-232 or RS-422 communications standards.
Chapter 3 Protocol Point-to-Point with XON/XOFF (Transmitter On/Off) Definition: This option enables the host to send the XON and XOFF command as a single byte transmission command of start (^Q) or stop (^S). Usage: If an XOFF has been received from the host, data will not be sent to the host until the host sends an XON. During the XOFF phase, the host is free to carry on other chores and accept data from other devices. Used only with RS-232.
Protocol Multidrop Note: See also “Multidrop Communications” on page A-32. Definition: Multidrop allows up to 50 devices to be connected to a single RS-485 host, with the scanner assigned an unique address (from 01 to 50). Usage: The MS-5000 can be used as a concentrator to a single host port connection. When Multidrop is selected, the protocol characters for RES, REQ, etc. are assigned automatically. Multidrop Addresses: Each address has its own separate poll and select address (from 1C to 7F hex).
Chapter 3 Protocol User Defined Example Definition: Example: ACK/NAK protocol can be configured using User Defined. The scanner will transmit data to the host, when an ACK is received, it will carry on with its business. If a NAK or response timeout occurs, the scanner will re-send the data to the host up to 3 more times before aborting. Tip: To use User Defined Point-to-Point, first select Point-to-Point and then User Defined .
Protocol User Defined Multidrop Definition: User Defined Multidrop allows the user to customize the polling protocol. Usage: This option is used when connecting to a concentrator or other device that does not match standard multidrop protocol. If selecting User Defined Multidrop (7), complete the format by either choosing new parameters or place commas where unchanged data fields occur.
Chapter 3 Protocol LRC (Longitudinal Redundancy Check) Definition: An error-checking routine that verifies the accuracy of transmissions. It is the exclusive OR of all characters following the STX (start of text) up to and including the ETX (end of text). What this means is that the binary representation of all the characters in a transmissions are cumulatively added in a column and each resulting odd integer is assigned a 1 and each even integer a 0 (two 1s = 0, two 0s = 0, a 1 and a 0 = 1).
Response Timeout Response Timeout Time the scanner will wait before timing out if ACK, NAK, and ETX are enabled, and a host response is expected. Usage: Only used when a response is required from the host. While in Multidrop, if the scanner does not receive an ACK or NAK from the host after sending polled data, it will act on a fault. The scanner can be set to wait indefinitely by setting Response Timeout to zero.
Chapter 3 Protocol Intercharacter Delay Definition: The time interval in milliseconds between individual characters transmitted from the scanner to the host. Usage: Intercharacter Delay is only used where a host cannot receive data quickly enough and there is enough time between labels to allow data to be completely transferred. It is rarely used since any setting other than zero will slow down communications.
Output Data Format Output Data Format Up to four user defined ASCII characters, including control characters can be defined and added to the front or end of the data string that is sent from the scanner to the host. Preamble Characters 3–Protocol Preamble Status Definition: Define a one to four character data string that can be added to the front of the decoded data. Usage: Useful for identifying and controlling incoming data.
Chapter 3 Protocol Postamble Characters Postamble Status Definition: Allows the user to enable or disable up to four postamble character(s) that can be added to the end of the decoded data. Usage: Useful for identifying and controlling incoming data. For example, defining the postamble as a carriage return and a line feed causes each decoded message to be displayed of on its own line.

Read Cycle/Trigger by ESP Click this Button to bring up the Read Cycle/ Triggering menu To change a setting, double-click the setting and use your curser to scroll through the options.
Chapter 4 Read Cycle/Trigger Read Cycle/Trigger by Embedded Menu For information on accessing the embedded menus, see “Embedded Menus” on page A-19.
Trigger Mode Trigger Mode Definition: The type of trigger event that will initiate the read cycle.
Chapter 4 Read Cycle/Trigger Continuous Read 1 Output Definition: In Continuous Read 1 Output the scanner self-triggers whenever it decodes a new bar code label or a timeout occurs. If End Of Read Cycle is set to Timeout and the label doesn't change, the scanner will repeat the output at the end of each timeout period.
Trigger Mode External Trigger Level Definition: External Trigger Level allows the read cycle (active state) to begin when a trigger (change of state) from an external sensing device is received. The read cycle endures until the object moves out of the sensor range and the active trigger state changes again. Usage: This mode is effective in an application where the speeds of the conveying apparatus are variable and the time the scanner spends scanning each object is not predictable.
Chapter 4 Read Cycle/Trigger External Trigger Edge Definition: External Trigger Edge, as with Level, allows the read cycle (active state) to begin when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read output or, depending on End of Read Cycle setting, a timeout or new trigger occurs.
Trigger Mode Serial Data Definition: In Serial Data, the scanner accepts an ASCII character from the host or controlling device as a trigger to start a read cycle. A Serial Data trigger behaves the same as an External Edge trigger. Serial commands are entered inside corner brackets, such as . Usage: Serial Data is effective in a highly controlled environment where the host knows precisely when the object is in the scan zone. It is also useful in determining if a noread has occurred.
Chapter 4 Read Cycle/Trigger Trigger Filter Duration Definition: Trigger Filter Duration can prevent trigger bounce from falsely triggering the scanner by limiting the time in which trigger pulses can be received. Usage: Trigger Filter Duration is useful where trigger bounce could cause false triggers. Serial Cmd: Default: 78 (x 128 µs = 9984 µs) Options: 0 to 65535 (corresponding to 0 to 2.048 s in 31.
External Trigger State External Trigger State Definition: When enabled for Active On (ION) (Positive) the triggering device imposes a current on the optoisolator to activate the read cycle. When enabled for Active Off (IOFF) (Negative) the triggering device interrupts the current to the optoisolator to activate the read cycle. Usage: Allows users to select the trigger state that will operate with their systems. (If using the Microscan object detector, use Active Off.
Chapter 4 Read Cycle/Trigger End of Read Cycle Definition: The read cycle is the time during which the scanner will attempt to read and decode a bar code symbol. Serial Cmd: End of Read Cycle Status A read cycle can be terminated by a new trigger, a timeout, or a combination of both. ESP: Double-click on End of Read Cycle Mode and make a selection.
End of Read Cycle Timeout Definition: Timeout ends the read cycle, causing the scanner to stop reading labels and send the label data or noread message when the time set in Timeout elapses (times out), if When to Output is set to End of Read Cycle. If in Continuous Read 1 Output, a timeout initiates a new read cycle and allows the same label to be read again.
Chapter 4 Read Cycle/Trigger New Trigger Definition: New Trigger ends the current read cycle and initiates a new one when a new trigger occurs. New Trigger refers only to a “rising edge” trigger. With either External Edge, Serial, or Serial or Edge enabled, an edge or serial trigger ends a read cycle and initiates the next read cycle. In the case of External Level, a falling edge trigger ends the read cycle but the next read cycle does not begin until the occurrence of the next rising edge trigger.
Multilabel Multilabel Definition: Multilabel allows the user to define up to 12 bar code labels that can be read in a single read cycle. Usage: Multilabel is commonly used in shipping applications where a shipping label contains individual bar codes for part number, quantity, etc. This feature allows one trigger to pick up all the labels. AIAG and UCC/EAN128 are two application standards that address this need.
Chapter 4 Read Cycle/Trigger Number of Labels Definition: Number of Labels is the number of different labels that can be read in a single read cycle.
Multilabel 4–Read Cycle/Trig- Multilabel Separator Definition: The character that’s inserted between each label scanned when Multilabel is set to any number greater than 1. Usage: Used to delimit or separate data fields with a user defined character. ESP: Double-click on Separator and select a character in the popup window.

Code Types by Embedded Menu 5–Codes For information on accessing the embedded menus, see “Embedded Menus” on page A-19.
Chapter 5 Codes Narrow Margins Definition: Usage: Serial Cmd: Default: Options: Allows the scanner to read symbols with quiet zones less than 8 times the width of the narrow bar element. “Quiet zone” is the space at the leading and trailing ends of a symbol. Each quiet zone can be as narrow as only five times the width of the narrow bar element when Narrow Margins is enabled.
Symbology ID Symbology ID Definition: Symbology ID is an AIM standard prefix character that identifies the bar code type. When enabled, the scanner analyzes and identifies the bar code symbology and adds a three character identifying prefix to the data: 1. ] (close bracket character) indicating the presence of a symbology ID 2. A, C, E, F, G, I, L, Q A = Code 39; C = Code 128 or UCC/EAN-128; E = UPC/EAN; F = Codabar; G = Code 93; I = I–2 of 5; L = PDF417; Q = Pharma Code 3.
Chapter 5 Codes Background Color Definition: Usage: Allows the user to choose which symbol background (white or black) the scanner can read. If the background is darker than the symbol, then enable black background. Typically the background is white; but on PCBs for example, they can be black.
Code 39 Code 39 Definition: Usage: An alphanumeric code with unique start/stop code patterns, composed of 9 black and white elements per character, of which 3 are wide. Code 39 is considered the standard for non-retail symbology. Code 39 Status Serial Cmd: Default: Enabled Options: Note: This is the only code type enabled by default.
Chapter 5 Codes Large Intercharacter Gap (Code 39) Definition: Usage: Serial Cmd: Default: Options: When enabled, the scanner can read symbols with gaps between bar code characters that exceed three times (3x) the narrow element width. Large Intercharacter Gap is helpful for reading symbols that are printed out of specification.
Code 39 Full ASCII Set (Code 39 Definition: Usage: Serial Cmd: 5–Codes Default: Options: Standard Code 39 encodes 43 characters; zero through nine, capital “A” through capital “Z”, minus symbol, plus symbol, forward slash, space, decimal point, dollar sign and percent symbol. When Full ASCII Set is enabled, the scanner can read the full ASCII character set, from 0 to 255. Must be enabled when reading characters outside the standard character set (0-9, A-Z, etc.
Chapter 5 Codes Codabar Definition: Usage: Codabar is a 16-character set (0 through 9, and the characters $, :, /, ., +, and –) with start/stop codes and at least two distinctly different bar widths. Used in photo-finishing and library applications. Formerly used in some medical applications but not typically used in newer applications.
Codabar Large Intercharacter Gap (Codabar) Definition: Usage: Serial Cmd: Default: Options: Instructs the scanner to read symbols with gaps between characters exceeding three times the narrow element width. It is helpful for reading symbols that are printed out of specification. Caution: Do not use Large Intercharacter Gap with Narrow Margins enabled since enabling Large Intercharacter Gap (over 3x) could cause a narrow margins (5x) to be interpreted as an intercharacter gap.
Chapter 5 Codes Check Digit Type (Codabar) Definition: Serial Cmd: Default: Options: Modulus 16: NW 7: Allows the user to select the check digit type Codabar will use. Disabled 0 = Disabled 1 = Modulus 16 2 = NW 7 3 = Both Used in the photo-finishing market. Used in Japanese markets.
Interleaved 2 of 5 Interleaved 2 of 5 Definition: Usage: A dense, continuous, self-checking, numeric symbology. Characters are paired together so that each character has five elements, two wide and three narrow, representing numbers 0 through 9, with the bars representing the first character and the interleaved spaces representing the second character. (A check digit is highly recommended.) Important: You must set Code Length in order to decode I 2/5 symbols.
Chapter 5 Codes Code Length #1 (Interleaved 2 of 5) Definition: Usage: Serial Cmd: Default: Options: Allows user to define the symbol length. Because I 2/5 is a continuous code, it is prone to substitution errors. Hence, a code length must be defined and a bar code symbol must contain an even number of digits. Note: If a start, stop or check digits are used, they are not included in the code length count. With I 2/5, two code lengths can be defined.
UPC/EAN UPC/EAN Definition: Usage: UPC (Universal Product Code) is a fixed length numeric, continuous symbology. UPC can have two or five digit supplemental bar code data following the normal code. The U.P.C., Version A (U.P.C., A) symbol is used to encode a 12 digit number. The first digit is the number system character, the next five are the manufacturer number, the next five are the product number, and the last digit is the checksum character.
Chapter 5 Codes Supplementals Status (UPC/EAN) Definition: Usage: Serial Cmd: Default: Options: Disabled: Enabled: Required: A supplemental is a 2 or 5 digit symbol appended to the main label. When set to Enabled or Required, the scanner reads supplemental bar code data that has been appended to the standard UPC or EAN codes. Reads Supplementals typically used in publications and documentation.
UPC/EAN Separator Character (UPC/EAN) Definition: Usage: Serial Cmd: Default: Options: Allows the user to change the separator character from a comma to a new character. As required by the application. , (comma) Any ASCII character Note: If Separator Character has been changed to any other character and you wish to re-define the separator as a comma, you will need to use ESP or the embedded menu.
Chapter 5 Codes PDF417 Definition: Usage: Serial Cmd: A two-dimensional, multi-row (3 to 90), continuous, variable length symbology that has high data capacity for storing up to 2700 numeric characters, 1800 printable ASCII characters, or 1100 binary character per symbol. Each symbol character consists of 4 bars and 4 spaces in a 17-module structure.
PDF417 Fixed Code Length Status (PDF417) Serial Cmd: Default: Options: Disabled 0 = Disabled 1 = Enabled Fixed Code Length (PDF417) Definition: Serial Cmd: Default: Options: Specifies the exact number of characters the scanner will recognize. 10 1 to 2710 5–Codes Note: Fixed Code Length Status must be enabled for Fixed Code Length to take effect.
Chapter 5 Codes Code 128 Definition: Usage: A very dense alphanumeric symbology. It encodes all 128 ASCII characters, it is continuous, has variable length, and uses multiple element widths measured edge to edge. Code 128 is a smaller code useful in applications with tight spots and high security needs.
UCC/EAN-128 UCC/EAN-128 Definition: Usage: A subset of Code 128, with extended features. See the Uniform Code Council, Inc. at www.uc-council.org. Used as a standard for shipping labels. Note: Code 128 must be Enabled for UCC/EAN-128 to function.
Chapter 5 Codes Application Record Separator Status (UCC/EAN-128) Definition: Serial Cmd: Default: Options: When enabled, a separator character is inserted between application records. Disabled 0 = Disabled 1 = Enable Note: Output Format must be set to Application Record before this parameter can take effect.
UCC/EAN-128 Application Record Padding (UCC/EAN-128) Definition: Serial Cmd: Default: Options: Padding is the insertion of zeros to make up the maximum length of a variable application record data field, except for the last field which does not require padding. When enabled, padding is included. When disabled, padding is omitted. Note: Padding is never added to fixed length fields or to the last data field of a label. Enabling or disabling Record Padding will have no effect on these.
Chapter 5 Codes Code 93 Definition: Usage: Code 93 is a variable length, continuous symbology employing four element widths. Each Code 93 character has nine modules that may be either black or white. Each character contains three bars and three spaces. Used occasionally in clinical industry.
AIAG AIAG Definition: Usage: 5–Codes ESP: AIAG is not a bar code symbology, but rather a standard that enables a user to add information to symbols and to filter data according to userdefined identifiers (up to 12). AIAG is the Automotive Industry Action Group standard and is applicable to all symbologies. If when AIAG is enabled a decoded symbol has an AIAG ID, it will be counted.

6–Scanner Setup Scan Speed Scan Speed (factory setting) Definition: Allows the user to set the number of scans per second by controlling the spinning mirror motor speed. Usage: Typically, to ensure a minimum number of scans, faster scan speeds are used for fast moving labels and/or longer labels with larger bar widths. See “Formulas for Number of Decodes” on page A-27.
Chapter 6 Scanner Setup (factory setting) Definition: Sets a voltage amplitude value for the analog circuitry. Usage: Can be useful for fine-tuning gain or when portions of analog signals spike as in the case of specular reflection or extraneous noise. Caution: Changes to Gain are typically done by qualified technicians i. Serial Cmd: Default: Default is 45 (nominal). Gain is optimized at the factory before shipment; the default value may not be 45.
6–Scanner Setup AGC Sampling AGC Sampling Definition: AGC is the acronym for Automatic Gain Control. AGC increases the depth of field by attempting to maintain signal strength at a constant level regardless of the range of the bar code label. AGC Sampling allows you to specify how automatic gain control sampling will be done.
Chapter 6 Scanner Setup (Read Only) Definition: Limits the hardware gain available to the software for the usable range. Serial Cmd: AGC Maximum (Read Only) Definition: Limits the hardware gain available to the software for the usable range.
6–Scanner Setup Transition Counter Transition Counter Used for both AGC and label detection routines (see Chapter 8, “Outputs”). Definition: During the read cycle, the scanner counts the number of bar and space transitions defined in the Transition Counter. If the count matches or exceeds the threshold, the scanner will perform AGC routines. The results of this test are also made known in output messages.See “Bar Code Output,” on page 8-8 and “Bar Code Output,” on page 8-8.

Chapter 7 Matchcode Matchcode by Embedded Menu For information on accessing the embedded menus, see “Embedded Menus” on page A-19.
Overview of Matchcode 7–Matchcode Overview of Matchcode Definition: With Matchcode you can store master label data in the scanner’s memory, compare this data against the scanned bar codes, and define how label data and/or discrete signal output will be directed. A master label database can be setup for up to 10 master labels. See “Master Label Database” on page 7-10.
Chapter 7 Matchcode Matchcode Type Definition: Allows the user to choose the way that master labels will be compared with subsequently scanned labels. Note: First set Triggering Mode to External or Serial. ESP: 7–Matchcode Serial Cmd: Default: Disabled Options: 0 1 2 3 Disabled: Has no effect on operations.
Matchcode Type 7–Matchcode Sequential Matching Definition: With Sequential enabled, Sequential Matching determines if a count is in ascending (incremental) or descending (decremental) order. Usage: Useful in tracking product serial numbers that increment or decrement sequentially.
Chapter 7 Matchcode Match Length Defines the length of the character string that will be compared with that of the master label when Match Start Position is set to 1 or greater. when Match Start Position is set to 0, no comparison will occur. Usage: For example, if Match Length is set to 6 in a 10 character symbol, and Match Start Position is set for 2, only the 2nd through 7th characters (from left to right) will be compared.
Matchcode Type 7–Matchcode Sequence On Noread Definition: When Sequence On Noread is Enabled and Matchcode is set to Sequential, the scanner sequences the master label on every match or noread. When disabled, it does not sequence on a noread. Usage: Sequence On Noread is useful when the scanner needs to stay in sequence even if no decode occurs.
Chapter 7 Matchcode Sequence On Mismatch Note: Matchcode must be set to Sequential for this command to function. When set to Enabled, the master label sequences on every decode, match or mismatch. When set to Disabled, the master label will not sequence whenever consecutive mismatches occur. Usage: Enable this parameter if every trigger event should have a decode and more than one consecutive mismatch may occur.
Master Label Database Master Label Database Important: Master Label Database is used only for comparing entire bar codes, when Sequential and Wild Card are NOT enabled, and Start Position is equal to 0. 7–Matchcode Master Label Database Overview Definition: Allows you to define up to 10 master labels as the master label database, which can be entered by keyboard, scanned-in, displayed, or deleted by serial or ESP commands.
Chapter 7 Matchcode Enter Master Label Data Definition: ESP: Allows you to enter master label data for a specific master label index number (1 to 10), provided the index number is not larger than the number of labels enabled by the Master Label Database Size (see page 7-10). For example, if Master Label Database Size is set to 2, you will not be able to enter data for labels 3 through 10. 1. Open the Utilities menu. 7–Matchcode 2.

Message Output The following flow chart explains the logic paths taken for Noread, Bad Bar Code and No Bar Code outputs. Note: When Transition Counter Status is enabled, the scanner will test for a minimum number of bar and space transitions. If that minimum threshold is met, a Bad Bar Code message is sent; otherwise a No Bar Code message is sent.
Chapter 8 Outputs Noread Message Definition: Usage: When enabled, and if no bar code label has been decoded before timeout or the end of the read cycle, the noread message will be transmitted to the host. Used in applications where the host needs serial verification that a label has not been read and especially useful in new print verification.
Bad Bar Code Message Bad Bar Code Message Definition: Usage: When enabled, a message is sent to the host when a label is detected but not decoded. See “Transition Counter Threshold” on page 6-10. The Bad Bar Code output is tied to the transition counter. If during a read cycle no symbol is decoded and the required setting for the Transition Sample Threshold is met, a Bad Bar Code message will be sent to the host. See “Output Message Flow” on page 8-4.
Chapter 8 Outputs No Bar Code Message Definition: Usage: When enabled, sends a message to the host whenever an object is detected but no bar code label is detected. See “Transition Counter Threshold” on page 6-10. The No Bar Code output is tied to the transition counter. If during a read cycle no symbol is decoded and the required setting for the Transition Sample Threshold is NOT met, a No Bar Code message will be sent to the host. See “Output Message Flow” on page 8-4.
Bar Code Output Bar Code Output Note: Bar Code Output relates to data and should not to be confused with Outputs 1, 2, and 3 listed in the Outputs Parameters which describe output states and functions. Bar Code Output Status Definition: 8–Outputs Usage: Serial Cmd: Default: Options: Defines the conditions under which decoded bar code labels are transmitted to the host. Useful when the host needs bar code data only under certain conditions.
Chapter 8 Outputs Mismatch Definition: Usage: With Mismatch enabled, the scanner transmits bar code data whenever the bar code data information does NOT match the master label. Note: A noread can still be transmitted if enabled. Mismatch is typically used as a flag within the host system to prevent an item from being routed in the wrong container. Good Read Definition: Usage: With Good Read enabled, the scanner transmits bar code data on any good read regardless of Matchcode Type setting.
Bar Code Output End of Read Cycle Definition: Enabling End of Read Cycle means that bar code data does not get sent to the host until the read cycle ends with a timeout or new trigger. End of read cycle Start of read cycle Read cycle Duration Host activates trigger This is when host expects output Figure 8-2 Read Cycle End of Read Cycle is useful in timing-based systems in which the host is not ready to accept data at the time it is decoded.
Chapter 8 Outputs Laser Control Laser On/Off Status Definition: Usage: Serial Cmd: Default: Options: When enabled, the laser is ON only during the read cycle. When disabled, the laser operates continuously. Laser On/Off extends the life of the laser. It is useful where there are significant time gaps between symbols. It also provides visual confirmation of a read cycle duration and minimizes laser exposure to people.
Laser Control Note: Because scan widths are not always perfectly symmetrical, the most effective way to setup laser framing is to experiment with the Laser On Percentage and Laser Off Percentage commands until you get the best results. Laser Off Percentage Definition: Serial Cmd: Default: Options: Percentage of time that the laser is OFF during the scan width sweep. When Laser Framing is disabled, the laser is ON during the full scan.
Chapter 8 Outputs Serial Verification Allows the user to verify configuration command status. Serial Command Echo Status Definition: Function: Usage: Default: Options: Serial Command Beep Status Definition: Function: Usage: Serial Cmd: Default: Options: Causes the scanner to beep once whenever a K command is entered to indicate that the command was accepted and processed. If an invalid command is entered, the scanner beeps 5 times to indicate an invalid entry.
Serial Verification Control/Hex Output Definition: Usage: Serial Cmd: 8–Outputs Default: Options: Determines the response to an Serial Command Echo or status request command. When set to Control, two characters are transmitted to represent a non-displayable character. For example, a carriage return will be shown as the two characters: ^M. When set to Hex, the output is the hex character. Useful for viewing settings with binary characters when using serial command on a terminal.
Chapter 8 Outputs Beeper Status Definition: A beep is emitted either after each good read of a bar code label or after each noread. Note: Beeper will also sound if any of the following occur: • the scanner is defaulted • a send/save command from ESP or an Exit command from any embedded menu Usage: • a , , , or command is sent Can be used as an audible verification that either a good read or a noread has occurred.
Partial Output Partial Output Definition: Usage: When enabled, allows you to pre-select portions of labels to be transmitted by the scanner. In Multilabel mode, partial output is performed on each separate label.
Chapter 8 Outputs Operation Command Output Definition: Usage: Serial Cmd: Default: Options: Directs the scanner to bracket non-bar code scanner data outputs such as counters with command start and stop characters and echo the command to the screen. Useful when brackets are required to delineate certain scanner outputs such as counters.

Embedded Menus Appendix G — Embedded Menus In addition to ESP-MP, you can also use a communications menu such as Microsoft’s HyperTerminal to establish communication with Microscan’s embedded menus.1 1. With your host connected to the configuration port, set your host communications settings as follows: 9600, 7, 1, and Even. 2. Set Flow Control to None. 3. Make the communications port selection. (Usually COM 1 or COM 2 for desktops and COM 1 for laptops.) 4.
Appendix H Appendix H — Defaulting/Saving/Initializing Defaults are original or saved settings. Defaulting occurs when default settings (from flash or user-saved NOVRAM) are restored. Defaulting might be necessary if you have make temporary changes, communications between the scanner and another device are lost or interrupted, or you are using incompatible equipment (for example, a terminal that is set at 9600 baud communicating with a scanner that is set at 38.4K baud).
Defaulting/Saving/Initializing Restore Flash Defaults to Active Memory and for Power-on Caution: Defaulting the scanner to flash default settings will overwrite user-saved NOVRAM settings. • Restores flash defaults to memory. Active Memory • Restores flash defaults to user-saved NOVRAM for power-on. • Initializes serial configuration commands in active memory and resets counters to zero. Initialize User-Saved NOVRAM Flash Defaults By Serial Command Send command to the scanner. By ESP 1.
Appendix H Saving Save Active Settings except Factory for Power-on • Initializes serial configuration commands in active memory and resets counters to zero.

By ESP Active Memory User-Saved NOVRAM Flash Defaults Right-click in the configuration window and select Save to Scanner, Send and Save.
Defaulting/Saving/Initializing Initializing Initializing is a part of all save and default functions. It is also used as a follow-on to implement serial configuration commands into active memory. • Initializes serial configuration commands in Initialize active memory and resets counters to zero. • Does not save settings to NOVRAM. Active Memory By Serial Command Send after a serial configuration command or a string of serial configuration commands, for example, .
Appendix I Appendix I — Position Scanner and Bar Code In positioning the scanner in relation to the bar codes being scanner, consider the following: • Position the scanner in a place devoid of sunlight, bright lights, or laser light from other sources. • Avoid excessive tilt, skew, or pitch. Maximum tilt is determined by label characteristics and the number of decodes required. Maximum skew is ±40°; maximum pitch is ±50°.
Position Object Detector Appendix J — Position Object Detector In a typical operation, a scanner will wait for bar code data only during a triggered read cycle. A read cycle is initiated by a “trigger” and can be in the form of a serial command from the host (internal trigger) or a signal from an object detector (external trigger). When an object detector (also called a sensor, package detector, etc.
Appendix K Appendix K — Test Decode Rate With a Static Label 1. Position a stationary bar code in front of a functioning scanner at the scan distance used in your application. 2. Enter a command to see the decodes per second. The decode rate is the number of decoded scans per total number of scan. It will appear at the beginning of the data strings. Note: You can also enter a command to see the percentage of decodes per scans. 3. Make a note of the decode rate.
Formulas for Number of Decodes Appendix L — Formulas for Number of Decodes To ensure reliable scanning, apply a minimum of five decodes to each bar code. Use the formulas below to calculate the number of decodes that your label will receive. If the number of decodes you derive from one of these calculations is less than the minimum for your application, plug in the minimum number of decodes (5) and solve for another parameter that might be changed, such as label speed or scans per second.
Appendix L Single Scan Line Picket Fence Calculation For single scan line picket fence scanning use the following formula: SW – LL ) (--------------------------× DR – 3 = number of complete decodes 1 LS Direction of label travel Example: LL = 2 inches (including quiet zones) LS = 100 inches per second Scan Line SW = 4 inches DR = 1000 decodes per second 4 – 2) (---------------× 1000 – 3 = 17 complete decodes 100 Figure A-9 Picket Fence Appendices Angled Picket Fence Calculation The numb
Formulas for Number of Decodes Label Speed Applies to both picket fence and ladder oriented labels. If your application allows it, slowing label speed (the time in seconds that a label is fully within the scan width of the scanner) is an effective way to increase the number of decodes. Label Dimensions, Label Density, and Label Ratio Not usually an option in most applications, but changes to label parameters can affect number of decodes calculations and possibly decode rates.
Appendix M Appendix M — Operational Tips Do: • Check inputs (label speed, length, height, etc.) to ensure the desired number of decodes per label. • For optimum decodes, mount scanner so that your labels pass through the center of the depth-of-field (minimum/maximum range). You find the center by moving your label in and out during a read rate test. • Avoid excessive tilt, pitch, and skew of the bar code label. • Check the bar code label for readability by doing a decode rate test.
Interface Standards Appendix N — Interface Standards Interface Standards, established by the Electronic Industries Association (EIA), specify such things as the signaling voltage levels, maximum cable lengths, and number of drivers. With Microscan devices, selection of interface is made by pin assignment and, in the case of the host communications, by software switching between RS-232 and RS-422. Microscan devices use RS-232, RS-422, and RS-485 multidrop.
Appendix O Appendix O — Multidrop Communications This appendix describes the rules for setting up a concentrator or controller to communicate with a scanner in standard Multidrop protocol. The diagram to the right shows a typical Multidrop network in which 1 to 50 scanners can communicate with a host via an intermediary device, a concentrator or a controller.
Multidrop Communications Connect to Scanner via the Concentrator You will need a multidrop concentrator and the required power supplies and cabling to communicate with your scanner(s). 1. From the Communications drop down menu, select Configure Multidrop to bring up the Multidrop Settings dialog. 2. If necessary, change the default address to match the address of your multidropped scanner and click OK.
Appendix O Polling Sequence Data that is transmitted to the host (bar code data, noread messages, counters, etc.) via concentrators is solicited by poll requests from the host. The polling sequence example by poll address 1E (ASCII hex value for Scanner 02) and a REQ (request). The scanner responds by first transmitting its own address, 1E, followed by a STX (start of text) character, and then the data. Next it transmits an ETX (end of text) character and an LRC (longitudinal redundancy check) character.
Multidrop Communications Select Sequence Unlike poll requests, select commands always originate from the host and consist of serial configuration or operation commands to devices that are configured in Multidrop. The scanner complies with the command when it is polled during the cycle.
