Theory of Operation

11.5.9.COMMUNICATION INTERFACE

The analyzer has several ways to communicate to the outside world. Users can input data and receive information directly via the front panel keypad and display. Direct communication with the CPU is also available by way of the analyzer’s RS-232 & RS-485 I/O ports or an optional Ethernet port. The analyzer can also send and receive different kinds of information via its external digital I/O connectors and the three analog outputs located on the rear panel.

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 Rack4.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 AnalyzersAPPENDIX 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-7Default Value Setup VariableNumeric Units Value RangeNumeric DefaultValue UnitsDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableSame settings as NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericMessage Text NameDescription APPENDIX A-3:Warnings and Test FunctionsMessage Text NameDescription A-22TEST FUNCTION NAME A-23MESSAGE TEXT DESCRIPTIONAPPENDIX A-3:Warnings and Test Functions A-24STABIL_SAMPLES TEST FUNCTION NAME A-25MESSAGE TEXT DESCRIPTIONBit or Channel Number Signal NameAPPENDIX A-4:Signal I/O Definitions APPENDIX A-4:Signal I/O DefinitionsBit or Channel Number Signal NameDescription A-27Number Bit or ChannelSignal Name DescriptionRear board temperature MUX analog inputs Signal NameBit or Channel Number DescriptionAPPENDIX A-4:Signal I/O Definitions Signal NameBit or Channel Number DescriptionDescription NameAPPENDIX A-5:DAS Triggers and Parameters A-31Description NameUnits A-32Description NameUnits A-33Table A-7:Terminal Command Designators APPENDIX A-6:Terminal Command DesignatorsAPPENDIX A-6:Terminal Command Designators COMMANDRegister Address MODBUSdec., 0-based MODBUS Floating Point Input RegistersMODBUS MODBUS Floating Point Holding RegistersDescription Unitssingle-bit; read-only MODBUS Discrete Input RegistersMODBUS Descriptionsingle-bit;read/write MODBUS Coil RegistersMODBUS Description04288D DCN5752 APPENDIX B - Spare PartsThis page intentionally left blank Part Number M300E Spare Parts ListDescription Reference: 05362J DCN5494 M300E Spare Parts ListPart Number DescriptionPart Number M300EM Spare Parts ListDescription Reference: 05424H DCN5494 M300EM Spare Parts ListPart Number Description6-10 M300EM Recommended Spare Parts Stocking Levels11-20 21-30Reference: 0096004C M300E/EX Expendables KitORIFICE, 13 MIL SAMPLE FLOW 000941000009550500 ASSY, SOURCE009560301 T300/T300M and M300E/EM APPENDIX C Warranty/Repair QuestionnaireEmail: api-customerservice@teledyne.com Please complete the following tableEmail: api-customerservice@teledyne.com APPENDIX C Warranty/Repair QuestionnaireT300/T300M and M300E/EM 2v/DIV04288D DCN5752 APPENDIX D – Wire List and Electronic Schematics04288D DCN5752 This page intentionally left blankInterconnect 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.schSchematics for PCA 03296, Sync Demod 1.
