Theory of Operation

11.5.2.CENTRAL PROCESSING UNIT (CPU)

The CPU for the E-Series instruments is a low power (5 VDC, 360mA MAX), high performance, Vortex86SX- based microcomputer running MS-DOS; its operation and assembly are compliant with the PC/104 Standard. The CPU is installed on the motherboard located inside the rear panel. It supports both RS-232 and RS-485 serial I/O.

The CPU includes two types of non-volatile data storage: a Disk-on-Module and an embedded flash chip.

DISK-ON-MODULE (DOM)

While technically an EEPROM, the DOM,is a 44-pin IDE flash drive with a storage capacity up to 128 MB. It is used to store the operating system for the computer, the Teledyne API’s Firmware, and most of the operational data generated by the analyzer’s internal data acquisition system (iDAS - See Section 7.1).

FLASH CHIP

Another, smaller EEPROM is the flash chip embedded in the CPU, which is used to store critical calibration and configuration data. Storing these key data on a separate, less heavily accessed chip significantly decreases the chance of the data being corrupted.

In the unlikely event that the flash chip should fail, the analyzer will continue to operate with just the DOM. However, all configuration information will be lost, requiring the unit to be recalibrated.

An anti-ESDwrist strap keeps the person wearing it at or near the same potential as other grounded objects in the work area and allows static charges to dissipate before they can build to dangerous levels. Anti-ESDwrist straps terminated with alligator clips are available for use in work areas where there is no available grounded plug 14.4.2.2.Working at an Anti-ESDWork Bench 14.4.2.1.Working at the Instrument Rack 4.Place the item in the container CAUTION – Avoid Warranty Invalidation ESD Hazard∙DO NOT use pink-polybags This page intentionally left blank A Primer on Electro-StaticDischargePage Page Page Page Page Page Warnings, This page intentionally left blank Technical Manual - Model 300E Family CO Analyzers APPENDIX A-1:SOFTWARE MENU TREES, REVISION L.8 TEST1 SAMPLEMSG1 RNGE PASS SAMPLE SETUPCLK MORE <TST TST> APPENDIX A-1:Software Menu Trees, Revision L.8 Figure A-3:Primary Setup Menu  DAS SubmenuACAL1 APPENDIX A-1:Software Menu Trees, Revision L.8 CO, 310, REPORTED CO2, 311, REPORTED SAMPLESETUPO2, 312 REPORTED APPENDIX A-1:Software Menu Trees, Revision L.8 Figure A-6:DIAG Menu A-7 Default Value Setup VariableNumeric Units Value Range Numeric DefaultValue Units Default Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O Numeric Default Setup VariableNumeric Value Default Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O Numeric Default Setup VariableNumeric Value Default Setup VariableSame settings as Numeric Default Setup VariableNumeric Value Default Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O Numeric Default Setup VariableNumeric Value Default Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O Numeric Default Setup VariableNumeric Value Default Setup VariableAPPENDIX A-2 Setup Variables For Serial I/O Numeric Message Text NameDescription APPENDIX A-3:Warnings and Test Functions Message Text NameDescription A-22 TEST FUNCTION NAME A-23MESSAGE TEXT DESCRIPTION APPENDIX A-3 Warnings and Test Functions A-24STABIL_SAMPLES TEST FUNCTION NAME A-25MESSAGE TEXT DESCRIPTION Bit or Channel Number Signal NameAPPENDIX A-4:Signal I/O Definitions APPENDIX A-4:Signal I/O Definitions Bit or Channel Number Signal NameDescription A-27 Number Bit or ChannelSignal Name Description Bit or Channel Number Signal NameDescription A-29 APPENDIX A-4:Signal I/O Definitions Signal NameBit or Channel Number Description Description NameAPPENDIX A-5:DAS Triggers and Parameters A-31 Description NameUnits A-32 Description NameUnits A-33 Table A-7:Terminal Command Designators APPENDIX A-6:Terminal Command DesignatorsAPPENDIX A-6:Terminal Command Designators COMMAND Register Address MODBUSdec., 0-based MODBUS Floating Point Input Registers MODBUS MODBUS Floating Point Holding RegistersDescription Units single-bit; read-only MODBUS Discrete Input RegistersMODBUS Description single-bit;read/write MODBUS Coil RegistersMODBUS Description 04288D DCN5752 APPENDIX B - Spare Parts This page intentionally left blank Part Number M300E Spare Parts ListDescription Reference: 05362J DCN5494 M300E Spare Parts ListPart Number Description Part Number M300EM Spare Parts ListDescription Reference: 05424H DCN5494 M300EM Spare Parts ListPart Number Description 6-10 M300EM Recommended Spare Parts Stocking Levels11-20 21-30 Reference: 0096004C M300E/EX Expendables Kit ORIFICE, 13 MIL SAMPLE FLOW 000941000009550500 ASSY, SOURCE 009560301 T300/T300M and M300E/EM APPENDIX C Warranty/Repair QuestionnaireEmail: api-customerservice@teledyne.com Please complete the following table Email: api-customerservice@teledyne.com APPENDIX C Warranty/Repair QuestionnaireT300/T300M and M300E/EM 2v/DIV 04288D DCN5752 APPENDIX D – Wire List and Electronic Schematics 04288D DCN5752 This page intentionally left blank Interconnect List, M300E/EU, SNs 100 and greater FROM FROM This page intentionally left blank Page Sync Demod Page 1 03297k_1.sch D C B ASync Demod Page 2 03297k_2.sch Sync Demod Page 3 03297k_3.sch Schematics for PCA 03296, Sync Demod 1.
