All rights reserved MS2020 Stratos Service Manual PRELIMINARY INFORMATION GENERAL PRECAUTIONS ** ESD PREVENTION STEPS MUST BE USED DURING ANY MODIFICATIONS AND/OR REPAIRS TO THIS UNIT! ** Product ESD Information This product contains ESD sensitive components, or ‘Electrostatic Discharge’ sensitive electronic parts. The Electrostatic discharge is defined as the transfer of charge between bodies at different electrical potentials. Electrostatic discharge has the ability to modify the electrical characteristics of a semiconductor device, possibly degrading or even destroying it. Electrostatic discharge also may upset the normal operation of an electronic system, causing equipment malfunction or failure. Laser Safety Information Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Under no circumstances should the customer attempt to service the scanner. Never attempt to look at the laser beam, even if the scanner appears to be nonfunctional. Doing so could result in hazardous radiation exposure. The MS7100 Unit is rated as a CLASS IIA laser product, as defined by The U.S. Federal Laser Product Performance Standard (FLPPS): Title 21 of the Code of Federal Regulations; Part 1000; [Parts 1040.10 and 1040.11]. Laser Classes CLASS I, II, and IIA lasers are defined as: • CLASS I: cannot emit laser radiation at known hazard levels (typically continuous (CW): 0.4microwatts at visible wavelengths). Users of a Class I laser products are generally exempt from radiation hazard controls during operation and maintenance (but not necessarily during service). • CLASS II: low power visible lasers, which emit above Class I levels but emitting a radiant power not above 1mW. The concept is that the human aversion reaction to bright light will protect a person. • CLASS IIA is a special designation that is based upon a 1000 second exposure and applies only to lasers that are "not intended for viewing" such as a supermarket laser scanner. These laser are emitting light in the visible wavelengths (0.4 to 0.7 mm) with power not above 1mW. 3 ©2004 Metrologic Instruments, Inc.

All rights reserved MS2020 Stratos Service Manual THEORY & OPERATION SCANNER OPERATION Startup When the scanner first receives power the white LED will flash, the blue LED will turn on and the scanner will beep once (the white LED will remain on for the duration of the beep). The scanner is now ready to scan. Power-Up Test Mode When a Stratos scanner is first powered up, it cycles through a number of self-tests before starting normal operation. If there are any initial failures during this sequence of tests the scanner will beep or razz to indicate the error and an error code will appear in the diagnostic indicator display. The following are examples of the types of tests performed at power-up. 1. 2. 3. 4. 5. 6. Memory tests Hardware setup tests Motor tests Laser tests Configuration tests Interface tests These tests are also performed on a periodic basis with the operator alerted to any failures. Programming Mode All MS2020 series scanners have been configured at the factory with a set of default communication protocols. Since many host systems have unique formats and protocol requirements, Metrologic provides a wide range of configurable features that may be selected with the use of the MetroSelect® Configuration Guide (MLPN 00-02407) or MetroSet. For a complete list of the factory default settings, refer to the Default Settings section of the MS2020 Stratos™ Series Installation and User’s Guide. 9 ©2004 Metrologic Instruments, Inc.

All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Audible When the MS2020 is in operation, it can provide audible feedback. These sounds indicate the status of the scanner. Eight settings are available for the tone of the beep (normal, 6 alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the Changing the Beeper Tone & Volume section of the Users manual. One Beep When the scanner first receives power the white LED will flash, the blue LED will turn on and the scanner will beep once (the white LED will remain on for the duration of the beep). The scanner is now ready to scan. When the scanner successfully reads a bar code, the white LED will flash and the scanner beeps once (if programmed to do so). If the scanner does not beep once and the white light does not flash, then the bar code has not been successfully read. Razzberry Tone This is a failure indicator. Refer to failure modes page 19 of this manual. Three Beeps - during operation When placing the scanner in program mode, the white LED will flash while the scanner simultaneously beeps three times. The white and blue LEDs will continue to flash until the unit exits program mode. Upon exiting program mode, the scanner will beep three times and the white LED will stop flashing. When configured, 3 beeps can also indicate a communications timeout during normal scanning mode. When using one-code-programming, the scanner will beep three times (the current selected tone), followed by a short pause, a high tone and a low tone. This tells the user that the single configuration bar code has successfully configured the scanner. Three Beeps - on power up This is a failure indicator. Refer to failure modes page 19 of this manual. 17 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Visual There is an array of LEDs (white and/or blue) located on the top of the hood of the MS202x. When the scanner is on, the flashing or constant illumination of the LEDs indicates the status of the current scan and the scanner. SCANNER LEDS No White or Blue LED The LEDs will not be illuminated if the scanner is not receiving power from the host or transformer. They are also not illuminated when all lasers are turned off for any reason. Steady Blue When all lasers are active, the blue LED is illuminated. The blue LED will remain illuminated until all lasers are deactivated. Steady Blue and Single White Flash When the scanner successfully reads a bar code, the white LED will flash and the scanner will beep once. If the white LED does not flash or the scanner does not beep once, then the bar code has not been successfully read. Steady White and Blue After a successful scan, the scanner transmits the data to the host device. Some communication modes require that the host inform the scanner when data is ready to be received. If the host is not ready to accept the information, the scanner’s white LED will remain on until the data can be transmitted. Flashing Blue then Flashing White This indicates the scanner is in program mode. A razzberry tone indicates that an invalid bar code has been scanned in this mode. or If the unit is in sleep mode, each LED will flash once every 15 seconds. Steady White, Blue Off This indicates the scanner may be waiting for communication from the host. 18 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Failure Modes Flashing Blue and One Razzberry Tone This indicates that the scanner has experienced a laser subsystem failure. The scanner will try up to 3 times to correct the failure condition. If the laser subsystem continues to fail, that subsystem (horizontal or vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This error stays on the display until corrected. If the remaining subsystem is still operational, scanning will continue using the operational components! Flashing Blue and White and Two Razzberry Tones This indicates that the scanner has experienced a laser subsystem failure. The scanner will try up to 3 times to correct the failure condition. If the laser subsystem continues to fail, that subsystem (horizontal or vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This error stays on the display until corrected. If the remaining subsystem is still operational, scanning will continue using the still operational components! Continuous Razzberry Tone with both LEDs off If, upon power up, the scanner emits a continuous razzberry tone, then the scanner has an electronic failure. Return the unit for repair at an authorized service center. Three Beeps - on power up If the scanner beeps 3 times on power up then, the nonvolatile memory that holds the scanner configuration has failed. Return the unit for repair at an authorized service center. 19 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Diagnostic Indicator Display This error display consists of a pair of seven-segment numerical displays for relating numerical error codes to the operator. It is located under the platter near the bottom right corner of the output window. The following is a list of possible error codes and their meanings. Some errors will require immediate scanner maintenance. Error display Diagnostic Error Code Chart Error Code Description 01 Reserved 02 RAM ERROR – The scanner’s Random Access Memory (RAM) is tested as faulty. Return the unit for repair at an authorized service center. 03 PROGRAM ERROR – The scanner’s software program is failing. Return the unit for repair. 04 INTERFACE ERROR – After power up and any application exit (e.g. MetroSet, etc.), the scanner checks the interface hardware with that chosen in configuration. If they do not agree, an interface error exists. Correct this problem by getting the proper hardware interface OR programming Stratos configuration for the proper interface hardware attached. 05 CONFIGURATION ERROR – The non-volatile configuration memory did not agree with the data last saved. Default configuration data is then used and the scanner continues operating. This error is also accompanied by 3 beeps. This error will remain during operation as a reminder that this power cycle is scanning against a defaultgenerated configuration. 20 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Diagnostic Indicator Display Error Code Description 11 SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error (always closed). The condition is self-correcting if possible. If the error persists, return the unit for repair at an authorized service center. The scanning operation can continue with this error active. 12 Reserved 13 SCALE ERROR – Single Cable Scanner/Scales Only. The scanner does not communicate with the scale. Make sure there is nothing plugged into the ‘Scale RS232 to Host’ port. If there is disconnect the cable, it may be causing the communication error. If there is still no communication between the scanner and scale return the unit to authorized service center for repair. 21 LASER #1 (vertical) ERROR – The laser in the vertical scanning subsystem denotes a failure. The scanner will try three times to correct the laser operation. If the laser error persists, the vertical scanning subsystem will be shut down and this error code will remain on the Diagnostic Indicators. If the horizontal scanning subsystem is still healthy, it will remain active and scanning can CONTINUE using the remaining good subsystem! The unit, however, should be scheduled for repair at an authorized service center when convenient. 22 LASER #2 (right horizontal) ERROR – The right laser in the horizontal scanning subsystem denotes a failure. The scanner will try three times to correct the laser operation. If the laser error persists, and the left horizontal laser (#3) is also in error, the horizontal scanning subsystem will be shut down and this error code will remain on the Diagnostic Indicators. If the left (Laser #3) horizontal scanning subsystem is still healthy, the horizontal scanning subsystem remains active and scanning can CONTINUE using the remaining good components! The unit, however, should be scheduled for repair at an authorized service center when convenient. 21 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING INDICATOR DESCRIPTIONS Diagnostic Indicator Display Error Code Description 23 LASER #3 (left horizontal) ERROR – The left laser in the horizontal scanning subsystem denotes a failure. The scanner will try three times to correct the laser operation. If the laser error persists, and the right horizontal laser (#2) is also in error, the horizontal scanning subsystem will be shut down and this error code will remain on the Diagnostic Indicators. If the right (Laser #2) horizontal scanning subsystem is still healthy, the horizontal scanning subsystem remains active and scanning can CONTINUE using the remaining good components! The unit, however, should be scheduled for repair at an authorized service center when convenient. 31 MOTOR #1 (vertical) ERROR – The motor in the vertical scanning subsystem denotes a failure. The scanner will try three times to correct the motor operation. If the motor error persists, the vertical scanning subsystem will be shut down and this error code will remain on the Diagnostic Indicators. If the horizontal scanning subsystem is still healthy, it will remain active and scanning can CONTINUE using the remaining good subsystem! The unit, however, should be scheduled for repair at an authorized service center when convenient. 32 MOTOR #2 (horizontal) ERROR – The motor in the horizontal scanning subsystem denotes a failure. The scanner will try three times to correct the laser operation. If the motor error persists, the horizontal scanning subsystem will be shut down and this error code will remain on the Diagnostic Indicators. If the vertical scanning subsystem is still healthy, it will remain active and scanning can CONTINUE using the remaining good subsystem! The unit, however, should be scheduled for repair at an authorized service center when convenient. 22 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING TROUBLESHOOTING CHART Symptom All Interfaces Possible Cause(s) Solution No LEDs, beep or motor spin. No power is being supplied to the scanner. Check the transformer, outlet and the power strip. Make sure the power cable is plugged into the scanner. No LEDs, and no beep. No power is being supplied to the scanner. The host system cannot supply enough current to power the MS2020 series scanner. Use the power supply included with the scanner. During power up the unit beeps 3 times. A Non-volatile RAM failure. Contact a Metrologic service representative, if the unit will not hold the programmed configuration. During power up the unit razzes continuously. A RAM or ROM failure. Contact a Metrologic service representative, if the unit will not function. During power up the unit razzes once and the blue LED flashes. A VLD failure. Contact a Metrologic service representative. During power up the unit razzes twice and both LEDs flash. Scanner motor failure. Contact a Metrologic service representative. There are multiple scans upon presentation of code. The same symbol timeout is set too short. Adjust same symbol timeout for a longer time. The beeper is disabled. Enable the beeper. No volume is selected. Select a volume. No tone is selected. Select a tone. The unit powers up but does not beep. 23 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING Troubleshooting chart Continued… Symptom Possible Cause(s) Solution All Interfaces Continued… The unit is trying to scan a particular symbology that is not enabled. The unit powers up but does not scan and/or beep. The unit has been programmed for a character length lock or a minimum length and the bar code being scanned does not satisfy the programmed criteria. UPC/EAN and Code 128 are enabled by default. Verify that the type of bar code being read has been selected. Verify that the bar code that is being scanned falls into the criteria. Typical of Non-UPC/EAN codes. The scanner defaults to a minimum of 4 character bar code. The unit scans a bar code, but locks up after the first scan (the white LED stays on). The scanner is configured to support some form of host handshaking but is not receiving the signal. If the scanner is setup to support ACK/NAK, RTS/CTS, XON/XOFF or D/E, verify that the host cable and host are supporting the handshaking properly. The unit scans but the data transmitted to the host is incorrect. The scanner’s data format does not match the host system requirements. Verify that the scanner’s data format matches that required by the host. Make sure that the scanner is connected to the proper host port. Scanner beeps at some bar codes and NOT from others of the same bar code symbology. The print quality of the bar code is suspect. Check the character length lock. The aspect ratio of the bar code is out of tolerance. The type of printer and/or the printer settings could be the problem. Check the print mode or change the printer settings.

The unit powers up but does not scan and/or beep. The unit beeps at some bar codes but NOT for others of the same bar code symbology. The unit has been programmed for a character length lock or a minimum length and the bar code being scanned does not satisfy the programmed criteria. UPC/EAN and Code 128 are enabled by default. Verify that the type of bar code being read has been selected. Verify that the bar code that is being scanned falls into the criteria. Typical of Non-UPC/EAN codes. The scanner defaults to a minimum of 4 character bar code. The bar code may have been printed incorrectly. Check if it is a check digit, character or border problem. The scanner is not configured correctly for this type of bar code. Check if check digits are set properly. The minimum symbol length setting does not work with the bar code. Check if the correct minimum symbol length is set. RS232 Only The unit powers up OK and scans OK but does not communicate properly to the host. The com port at the host is not working or is not configured properly. The cable is not connected to the proper com port. Check to make sure that the baud rate and parity of the scanner and the communication port match and the program is looking for “RS232” data. The com port is not operating properly. 25 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING Troubleshooting chart Continued… Symptom Possible Cause(s) Solution RS232 Only Continued… The host is receiving data but the data does not look correct. The scanner and host may not be configured for the same interface. Check that the scanner and the host are configured for the same interface. Characters are being dropped. The intercharacter delay needs to be added to the transmitted output. Add some intercharacter delay to the transmitted output by using the MetroSelect Configuration Guide (MLPN 00-02407B). Aux Port Operation With Any Interface The secondary scanner is not functioning. Refer to the user’s guide provided with the secondary scanner. Cable (MLPN 54-54667) may not be connected to the proper port. The secondary scanner powers up but data is not relayed to the host. Ensure that the secondary scanner is connected to the MS2020 com port marked “Aux” port. * The MS2020 series must be programmed to enable the auxiliary port. The auxiliary com port may not be operating properly. The auxiliary input port’s data format must match the main output format of the secondary scanner. * Use MetroSet. For the auxiliary interface, choose “HoloTrak Decode” All remaining parameters will be automatically chosen. 26 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual TROUBLESHOOTING RS232 DEMONSTRATION PROGRAM If an RS232 scanner is not communicating with your IBM compatible PC, key in the following BASIC program to test that the communication port and scanner are working. This program is for demonstration purposes only. It is only intended to prove that cabling is correct, the com port is working, and the scanner is working. If the bar code data displays on the screen while using this program, it only demonstrates that the hardware interface and scanner are working. At this point, investigate whether the application software and the scanner configuration match. If the application does not support RS232 scanners, a software wedge program that will take RS232 data and place it into a keyboard buffer may be needed. This program tells the PC to ignore RTS-CTS, Data Set Ready (DSR) and Data Carrier Detect (DCD) signals. If the demonstration program works and yours still does not, jumper RTS to CTS and Data Terminal Reading (DTR) to DCD and DSR on the back of your PC. 10 20 30 35 40 50 60 70 100 110 32766 32767 CLS ON ERROR GOTO 100 OPEN “COM1:9600,S,7,1,CS0,DS0,CD0,LF” AS #1 PRINT “SCAN A FEW BAR CODES” LINE INPUT #1, BARCODE$ PRINT BARCODE$ K$ = INKEY$: IF K$ = CHR$(27) THEN GOTO 32766 GOTO 40 PRINT “ERROR NO.”; ERR; “ PRESS ANY KEY TO TERMINATE.” K$ = INKEY$: IF K$ = “” THEN GOTO 110 CLOSE: SYSTEM END 27 ©2004 Metrologic Instruments, Inc.

The scale operation can be integrated into the software of Stratos. Presently, the scale cannot be configured from the scanner. The scale is configured with a down load file/utility on the PC. The following bar codes are to let the scanner know the configuration of the scale so it can refute commands that do not make sense to the scale configuration, if needed. Use the English Scale Defaults bar code to lay a template of English mode operation into the scanner’s memory. This will not change scanner defaults.

All rights reserved MS2020 Stratos Service Manual ORDERING PARTS AND GENERAL SERVICING INFORMATION IMPORTANT SITE INSTALLATION INFORMATION Before installing your Stratos scanner/scale, please consider the following items! Vertical Clearance A minimum clearance height of 7.50" from the check stand surface is needed for the vertical 'hood' on all of the scanner models. Additional clearance is recommended for unobstructed LED viewing by the operator. Ventilation and Spacing All Stratos models have a die-cast housing to dissipate heat allowing the unit to operate without a ventilation fan. Metrologic recommends that the temperature surrounding the unit does not exceed 40°C (104°F). There should be adequate convection and minimal heat producing equipment in close proximity of the unit. A cooling fan with a filter is recommended if there will be a conveyor motor or other heat producing equipment close to the unit that will create a high temperature environment. Adequate spacing between the unit and the check stand opening is required for proper operation of the scale. When the scanner/scale model is mounted properly, the scale platter should be able to move up and down freely without hitting the edges of the check stand cutout. Refer to Installing the Unit in the Counter for detailed cutout dimensions and mounting instructions. Service Access When routing and installing the cable(s) and power supply, make sure you leave access that these components may be swapped easily without the need to remove the unit from the check stand. When changing the StratosSWAP optics engine modules, Metrologic recommends removing the unit completely from the check stand. When calibrating or zeroing the scale, do not remove the unit from the check stand. Refer to the Scale Operation Section of this guide for detailed instructions on zeroing and calibration. Power Installation The Power Supply (AC/DC) should be connected to an AC Outlet that is free of electrical noise (clean). A qualified electrician can determine the amount of electrical noise on the AC line. See additional information on power installation and restrictions on pages 31 - 45. 83 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual ORDERING PARTS AND GENERAL SERVICING INFORMATION Check Stand Layout Considerations When placing a scanner in a check stand, the following factors should be considered. • Items should flow at a distance to the operator that maximizes comfort. The operator should not need to stretch or strain to reach for and scan packages. • The Stratos can scan a bar code on all 6 sides of a package. The packages should flow into the scan area that provides the maximum reading performance. No lifting or orientation of the items is necessary. A properly placed item diverter can maximize the flow of packages. • In what direction are the packages flowing? Most check stands are designed for lefthanded takeaway. If the operator is facing the vertical window of the scanner, packages flow from the operator's right to left. The packages are in queue on the conveyor to the right and the bagging is to the left. 84 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual ORDERING PARTS AND GENERAL SERVICING INFORMATION SCANNER TERMS & GLOSSARY StratosSYNCTM Stratos’s vertical and horizontal scanning zones operate totally independently from one another. If one scanning plane were to go down, the other will keep on scanning allowing no interruption to the checkout process and keeping customers moving through the checkout lane. StratosSWAPTM Modular optics engine technology, which are pre-aligned, field replaceable modules that pop into place within minutes. Stratos incorporates two StratosSWAP modules. The first is for the vertical scanning plane and the second is for the horizontal scanning plane. Both optics modules come equipped with the necessary electrical/mechanical/optical components necessary to produce the laser scan zone. No alignment or power level settings are required, the vertical and horizontal modular optics engine are simply Plug N Play. StratosSCOPETM An LED indicator that provides a 2-digit code that signifies and references a condition within the scanner. This feature allows an operator to easily determine the status of the scanner and quickly identify any error conditions that may exist or scanner/scale component that may require service. StratosSCHOOLTM StratosSCHOOL when enabled will store information on whether the product/barcode was decoded at the vertical window, horizontal right or horizontal left window or scanned via a hand-held scanner that is attached the aux. RS232 port. This information will be reported to a graphical statistical application, which will display the scanning statistics via a bar chart percentage format. Managers will be able to take this data and determine whether their operators are scanning inefficiently by favoring one scanning plan over the other. The primary objective of Stratos is to allow an operator to successfully scan a product without having to orientate the product. StratosSCHOOL will provide information as to whether the operator is using safe and efficient scanning techniques. 85 ©2004 Metrologic Instruments, Inc. All rights reserved MS2020 Stratos Service Manual ORDERING PARTS AND GENERAL SERVICING INFORMATION StratosSTATSTM StratosSTATS is a software tool standard within Stratos that will provide information on the quality of the barcodes that can be found on products. Poorly printed barcodes on products will cause the operator to pass the product through the scan zone more than once in order to achieve a successful scan. In many cases the barcode is of such poor quality that the operator will need to enter the product UPC code into the POS system via keyboard entry. Both of these scenarios will add unwanted time to the checkout process and will have a negative impact on productivity and customer satisfaction. StratosSTATS leverages off the UCC ANSI rating system, which grades a barcode with an A, B, C, D, or F to indicate barcode quality. StratosSTATS when enabled will append a quality rating to the product be read and store this data for uploading into a laptop or PC. Store managers will be able to gather and analyze this data and isolate which are the products that are slowing up the checkout process. Store managers can use this information to work more closely with their product vendors in order to improve the quality of the barcodes/products. Flash ROM The MS2020 comes standard with Flash ROM, allowing the user to upgrade the firmware. If new bar code standards are introduced, improvements are made to scanner, or new features are added, Flash ROM gives the end user the flexibility and peace of mind knowing that the scanner can be upgraded without the need to send it back to the factory. Electronic Article Surveillance (EAS) EAS is used in retail applications as a theft deterrent. The MS2020 is equipped with an EAS deactivation antenna in all units shipped from the factory. Sleep mode The MS2020 is equipped with multiple sleep mode options. For added flexibility, the laser and motor can be set for different timeout delays or sleep modes. Scanners installed in idle checkout lanes can be set to go to sleep faster, saving power and ultimately saving cost during dormant periods. Scanners installed in high-traffic lanes, can be set for a fast-wakeup mode, so that the checkout lane is not slowed by a slow wakeup time. The MS2020 default sleep mode provides instantaneous wakeup using IR activation. Scan Speed Faster scans per second in high-speed applications leads to faster checkout times with cost savings to end-users and increased customer satisfaction. The MS2020 series scanners has a scan rate of 6000 scans per second. Scan Performance StratosSCAN and StratosSPHERE combine to allow Stratos to have exceptional scan aggressiveness, First Pass Read Rate (FPRR) and decode capability with poor quality barcodes. The MS2020 and its 6 sides allows for less product orientation and the MS2020’s exceptional scan coverage for operator side scanning allows for aggressive scanning of barcodes that pass through the sweet spot (center of horizontal glass). 86 ©2004 Metrologic Instruments, Inc.
