Selectthe baseVO address,. Choose8 differential or 16 single-endedanaloginput channels,. Selectthe activechannel,. Selectthe channelgain,. Selectthe analoginput voltagerangeandpolarity,. Conrol 16TTL/CMOS-compatibledigital VO lines,. Control three l6-bit, 8 MHz timer/countercircuits (theprogrammableinterval timer),. Monitor theA/D conversionusingtheend-of-convert(EOC)signal,. Generateintemrptsignals.Many of these functions are set up at the factory, basedon typical data collection requirementsand customerspecificationswhenordering.Therefore,you cansuccessfullyinstall andrun theAD2000 with minimal understandingaboutchangingandcontrolling them.On the otherhand,you may want to understandeverythingahut your boad sothat you caneffectively useeachfeature.With this in mind, this manualprovidesbasicinformationto get theboardupof eachfunction.andrunning,aswell asdetailedinformationfor a full understandingi-1

CHAPTER 1RUNNINGQUICK START GETTING YOUR AD2OOO

To get startedusingyour AD2000 interfaceboard,you must:- Selectby jumpera baseI/O addresswhich doesnot contendwith any ottrerperipheraldevice.- Installtheboardino yourPC.- Connecta signalto oneofthe analoginputchannels.- Run the AD2000 software.Unlessyou haveotherrequirements,thesestepsareall that are necessaryto useyour AD2000 board.This chapterexplainshow to insrallyoru AD2000anduseits basicfunctions.You will learnhow to:. Changethe baseVO addresssetring,. Install the boardin your PC,. Initialize the board,. Selectthe analoginput channeland gain,. Take an A/D reading.This chapterallows you to immediately start using the basic functions of your AD2000 board for daa collectionapplications.This chapterdoesnot explainhow !o rammablenordoesitexplainhowto ibedin Chapters2 through4.I/Ofunctionsnotcoveredseuingsexceptfor the base address.What ComesWith Your AD2000The standardAD2000 boardpackageincludes:1IIAD20005.5-inch (1a0mm)interfaceboard(fits short slot)AD200Odemodiskuser'smanualAdditional items, suchas the AD2000 2-cableset (order numberXK40-l), extenderboardsor SIGNAL*MATH orATLANTIS applicationsoftware,areavailablefor this boardandare includedon an as-orderedbasis.All signalson your board are madeeasily accessiblewith Real Time Devices' XB40 VO extenderboard and XC40expansioncable.The extenderboardhastwo 20-pinterminalstripsanda prototypeareato supportany specialcircuitryyou mayrequireto conditionthesignals.For example,if you areprototypingsolid-staterelaysor optoisolalors,this caneasily be done with an XM0.

A completelisting of the board specificationsis containedinAppendix A. The AD2000 hasseveralfeatureswhich are user-controlledthroughhardwareor software.Most of ed;theremainingare switch nyslot(shortor full-size) in an IBM PC/XT/AT or compatiblecomputer.Two 4Gpin connectorson the board, P8 and Pl5,accommodateall of theboard'sextemalI/O. In operation,theseconnectorsarecabledsothat all S0linesareaccessibleat the rearpanelof ttrecomputer(seethe boardinstallationinstructionslater in this chapter).FunctionsYou Can SetTo allow the AD2000 interfaceboardto be adaptedto your needs,severalfunctionscanbe setup to perform specifictasksby changingthe hardwareconfigurationor throughsoftware.Table l-1 lists eachfunction you can control, thefacory (or default) settingif applicable,and wherein this manualyou can find informationaboutits settings.l-l
