1–Setup and Inst. Chapter 1 Setup and Installation Ground and Shield Considerations Proper grounding is necessary for operator safety, noise reduction, and the protection of equipment from voltage transients. Buildings–including any steelwork, all circuits, and all junction boxes–must be grounded directly to an earth ground in compliance with local and national electrical codes. RS-232 signals have a common signal ground (pin 7 of the 25-pin connector).

Chapter 2 Menu Configuration Entering the Menu Configuration Program To see the Main menu (figure 2-1), from an ASCII terminal that is connected to the decoder, send the serial command (enter the < > brackets as well as the upper case D).1 2–Menu Config. xx Figure 2-1 Configuration Program - Main Menu2 If the menu does not appear, see Appendix D, “Troubleshooting,” on page A-6. Using the Menu Configuration Program The bottom line on the screen is called the command line.
For example, to enable LRC (see figure 2-2, “Communications Menu Structure,” on page 2-5 and “Longitudinal Redundancy Check” on page 2-10), you would use the following command line path: From the Main menu, press CR at the Communications prompt (this is the first prompt displayed in the Menu Configuration Program) to access the Communications menu.
Chapter 2 Menu Configuration Saving Menu Changes Press ESC (escape key) to see the following on the command line: Press M to return to the Main menu, or press E to exit the Menu Configuration program. If E is pressed, the following question will appear: 2–Menu Config. Press N to exit without saving changes, or press Y to retain the current settings to non-volatile RAM for power up. If Y is selected, a beep will indicate the save has been carried out.
Communications Menu Communications Menu The Communications menu allows you to set the communication protocols between the decoder and the host. Communications – Bold text represents default settings. Host Protocol Protocol – – – – – Preamble – User Defined – User Defined Multidrop – RES – RES – – – Postamble Disabled Enabled – Address = ^A – REQ – EOT – Address = ^A – REQ – EOT LRC – Preamble Point-to-Point – ^M Point-to-Point – User w/RTS/CTS Definable (ASCII char.
Chapter 2 Menu Configuration There are three subtopics in this menu: Host Protocol, Host Port, and Aux Port. To help visualize the menu’s organization and to locate the page number where each topic is described, see figure 2-2, “Communications Menu Structure,” on page 2-5. Note: Changes in Communications parameters or assigning an address to the decoder can cause loss of communications with the configuration terminal when you exit the menu program (whether or not changes are saved for power-on).
Communications Menu Selecting: Has this effect: Used only with RS-232 or RS-422. This selection enables the host to send a single byte transmission command of start (XON) or stop (XOFF). 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. Point-to-Point with RTS/CTS and XON/XOFF Used only with RS-232.
Chapter 2 Menu Configuration Selecting: Has this effect: Used only with RS-232 or RS-422. ASCII characters can be assigned as an address and as protocol commands (RES, REQ, EOT, STX, ETX, ACK, and NAK). User Defined is necessary when a new protocol must be defined to match a specific NOTE: Note: AAspecific specificASCII host protocol.
Communications Menu Preamble Default: Preamble (enable/disable) Default: Disabled Options: Disabled, Enabled (within any protocol) Allows you to enable or disable the preamble character(s). Postamble Default: ^M^J. Corresponds to (carriage return/line feed) displayed in the menu. Options: Any ASCII character, including control characters. Control characters entered on the command line are displayed in the menu as mnemonic characters.
Chapter 2 Menu Configuration Longitudinal Redundancy Check Default: Disabled (in unpolled mode), Enabled (in polled mode) Options: Disabled, Enabled An error-checking routine that verifies the accuracy of transmissions. It is the exclusive OR of all characters following the SOM (start of message) up to and including the EOM (end of message). 2–Menu Config. Response Timeout Default: 12 ms Options: 0 to 65,000 ms. A zero (0) causes an indefinite wait.
Communications Menu Stop Bits Default: One Options: One, Two Allows you to select the last one or two bits in each character to indicate the end of the character. Data Bits RS-422 Default: Disabled Options: Disabled, Enabled Note: Used only in Point-to-Point protocol only, and not with RTS/CTS. Whenever RS-422 is disabled, RS-232 is enabled in the background. However, when Multidrop is enabled, the functioning protocol is RS-485 regardless of the displayed status of RS-422 in the menus.
Chapter 2 Menu Configuration Aux Mode Default: Disabled Options: Disabled, Transparent, Half Duplex, Full Duplex Aux Mode (auxiliary mode) allows you to select a communications mode for auxiliary operations (see Appendix H, “Auxiliary Monitor,” on page A-13). 2–Menu Config. Other Aux Port Parameters The other Aux Port parameters—Baud Rate, Parity, Stop Bits, and Data Bits—are identical to the host port parameters and are changed in the same manner (see page 2-10).
Operations Menu Operations Menu The Operations menu allows you to set the operations parameters for the decoder. To help visualize the menu’s organization and to locate the page number where each topic is described, see figure 2-3.
Chapter 2 Menu Configuration Triggering Mode Default: Continuous Read Options: Continuous Read, Continuous Read 1 Output, External Level, External Edge, Serial Data, Serial Data & External Edge Allows you to establish the type of trigger event that will initiate or end the read cycle. (See “End of Read Cycle” on page 2-16.) 2–Menu Config. Selecting: Continuous Read NOTE: If Continuous Read is enabled with Match Code, the decoder defaults to Continuous Read 1 Output mode.
Operations Menu Selecting: Has this effect: As with Level, Edge allows a read cycle to be initiated by a trigger signal from an object detector when it detects the appearance of an object (rising edge). But unlike Level mode, the removal of an object (falling edge) does not end the read cycle. With Edge enabled, the read cycle ends with a good read, a timeout, or a new trigger (figure -1).
Chapter 2 Menu Configuration End of Read Cycle 2–Menu Config. Default: Timeout Options: Timeout, New Trigger, Timeout & New Trigger Allows you to choose the conditions that will end the read cycle. The read cycle is the time during which the decoder will receive and process label data. When the Triggering Mode option is set in an External or Serial mode of operation, the trigger event initiates the read cycle.
Operations Menu Has this effect: Timeout & New Trigger Ends the read cycle after a specified period of time or at the occurrence of new trigger event, and if no label has been read, causes a noread message, if enabled, to be transmitted. With either External Edge, Serial Data, or Serial Data & Edge enabled, a timeout, or an edge or serial trigger, whichever comes first, ends the read cycle. An edge or serial trigger also initiates a new read cycle.
Chapter 2 Menu Configuration host command and requires the same command format as all host commands (that is, to be entered within the < > brackets). External Trigger Polarity 2–Menu Config. Default: Positive Options: Positive, Negative Note: External Level (page 2-14), External Edge (page 2-15), or Serial Data & Edge (page 2-15) must be enabled for External Trigger Polarity to take effect. “N/A” is displayed in the menu when all other triggering modes are enabled.
Operations Menu When to Output Default: As Soon As Possible Options: As Soon As Possible, End of Read Cycle Allows you to choose when bar code data is sent to the host. Selecting: Has this effect: Causes bar code data (good reads) to be transmitted immediately upon a good decode. End of Read Cycle Causes bar code data output to be delayed until the end of the read cycle.
Chapter 2 Menu Configuration 2–Menu Config. With Match Code enabled, a master label can be entered in three ways: 1. With New Master Pin enabled (see page 2-31), toggling pin 25 to ground (pin 7) enables the next good read to be the master label. 2. Sending serial command enables the next good read to be the master label. 3. Sending serial command <)XXXX)> downloads data as master label. (Master label data is entered in place of the Xs.
Operations Menu Number of Labels Field Separator Default: , (comma) Options: Any available ASCII character, except NUL. Allows you to choose the separator character to be inserted between labels. MS-3000 Single Head Decoder User’s Manual 2-21 2–Menu Config. Default: 1 Options: 1 to 6 Note: If Number of Labels is set to any number greater than one while Match Code or Continuous Read 1 Output is enabled, Number of Labels will default back to one.
Chapter 2 Menu Configuration Code Types Menu The Code Types menu allows you to choose among five bar code types and define their parameters. Code Types – Bold text represents default settings. Narrow Margins Status – 2–Menu Config.

Appendices Appendices Appendix C — Defaulting the Decoder Defaulting the decoder resets the decoder configuration parameters to their original default values. Defaulting is necessary if: • You wish to quickly restore default settings to the configuration program after making some temporary changes.1 • Communications between the decoder and another device are interrupted because of incompatible settings (for example, a terminal is set to communicate at 9600 baud, but the decoder is configured at 38.
Defaulting the Decoder If a profile card is not accessible, it is necessary to default the decoder by shorting pins 7 and 11. Caution: Be certain that the correct pins are shorted. Shorting the wrong pins can cause serious damage to the unit. Procedure: 1. Turn power to the decoder ON. 2. Locate pins 7 and 11 on the host connector (figure A-4) and mark with a pen. (Use a small length of light wire approx. 4 inches, 18 to 26 gauge for shorting.) 3. Momentarily short pins 11 and 7.
Appendices Appendices Appendix D — Troubleshooting The MS-3000 decoder, when used correctly with a properly adjusted scan head, should produce good reads (see scan head user’s manual). If not, A-3 lists some of the more common problems associated with setting up and using the decoder. If you are unable to locate or correct the problem, call your Microscan representative.
Troubleshooting Problem Decoder does not transmit or decode labels (decoder indicator lights on but no data is displayed on screen) Possible Cause Decoder is not triggered when in external mode. Ensure trigger device is operating properly. Do Read Rate Test . If it reads successfully, the problem is triggering. Decoder is not triggered when in serial mode. Ensure serial trigger character is sent with start/ stop characters (a left angle bracket < (unless redefined) and a right angle bracket >).
Appendices Appendices Table A-3 Troubleshooting Table (continued) Problem Getting only noread messages on the screen Previous label read, but subsequent label will not read Decoder not communicating in polled mode. Decoder not entering read cycle (trigger not working) Decoder not reading during the read cycle A-8 Possible Cause Solution Label misaligned or reflecting direct laser light Ensure the label is not excessively skewed, tilted, or otherwise disoriented.
Interfacing with the MS-90 Scan Head This appendix describes Label Speed, a User Outputs option (see figure A5) that is exclusive to the MS-90 scan head. When using a MS-90 scan head with an MS-2000/ 3000 decoder, it is necessary to install MS-90 firmware (35-213034-XX) that makes Label Speed available.1 Other than the differences noted in this appendix, configuration for the MS90 is identical to standard single scan head configuration described in this manual.
Appendices Appendices Setting the correct label speed is important when using the MS-90 with the MS-3000 decoder. Tables A-6 and A-7 show label speeds in inches per second for Slow, Medium, and Fast menu label speeds for 2.5:1 ratio (as used in Code 39) and 4:1 ratio (as used in Code 128) respectively.
Bar Code Symbology Appendices Appendix F — Bar Code Symbology Some factors to consider before choosing a bar code symbol are:1 • the type of information to be scanned (numeric only, alphanumeric) • the length of the messages to be encoded • how and where labels are to be applied • label printer capabilities • scan speed • beam width • the space available on the object to be identified • host software limitations • range of the scan head • the speed of the conveyor Microscan standard decoder firmware su
Appendices Appendices Appendix G — 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.
Auxiliary Monitor Appendices Appendix H — Auxiliary Monitor An auxiliary monitor, via a 9-pin cable connected to the decoder with a D-subminiature connector, can: 1. Echo data from the decoder or host. 2. Send data to the host. 3. Access and make changes to the decoder's configuration menus. The monitor can be configured to operate in one of three modes: • Transparent • Non-Buffered Half Duplex • Non-Buffered Full Duplex Note: Transparent can be used with all protocols.
Appendices Appendices Data initiated from the Decoder • Transmission to the monitor occurs immediately upon a good read. • Scan data to the monitor does not include a preamble or a postamble. • Communications with the monitor is always in Point-to-Point protocol, even if the host is in a polled protocol mode. Host Monitor Data initiated from the Host • In polled mode, data echoed from the host to the monitor must be in the format (e.g.
Auxiliary Monitor Data initiated from the Decoder • Scan data is transmitted to the monitor at the same time it is transmitted to the host. Host • Data transmission conforms with all parameters specified in the configuration menu (e.g., Preamble, Postamble, End of Read Cycle). Monitor MS-3000 Decoder Data is initiated from the Host • In polled mode, data echoed from the host to the monitor must be in the format (i.e.
Appendices Appendices Full Duplex Mode In full duplex mode, all monitor data and bar code data is sent directly to the host. Bar code data is not displayed on the monitor screen. Data initiated from the Monitor • Monitor data is passed directly through to the host whenever it is received by the MS-3000, unless the decoder is in a polled mode, in which case the data will be ignored. Host Monitor • Monitor data is not echoed. • Monitor data to the host will not have a preamble or a postamble.
Multidrop Communications This appendix describes the rules for setting up a concentrator or controller to communicate with a decoder in standard Multidrop protocol, as presented in “Protocol,” on page 2-6. Figure A-6 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 Addresses Host Concentrator or Controller • No two decoder in the Multidrop Network can have the same address.
Appendices Appendices 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. Start of Sequence Concentrator Decoder 02 End of Sequence RES 1E REQ ACK 1E STX DATA ETX LRC RES Figure A-7 Polling Sequence The polling sequence example in figure A-7 begins with a RES (reset) from the concentrator followed by poll address 1E (ASCII hex value for Decoder 02) and a REQ (request).
Multidrop Communications 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 decoder complies with the command when it is polled during the cycle. Figure A-8 is an example of a select sequence. Start of Sequence Concentrator RES 1F REQ Decoder 02 End of Sequence STX ETX LRC 1F ACK RES 1F ACK Figure A-8 Select Sequence A RES (reset) is the first command in the select sequence.
