Ground the
System
Tominimizeshockhazard,thechassisandsystemcabinetmustbeconnectedto
anelectricalground.Athree‐conductorACpowercableshouldbeused.The
powercablemusteitherbepluggedintoanapprovedthree‐contactelectrical
outletorusedwithathree‐contacttotwo‐contactadapterwiththegrounding

TheseswitchesareusedwhenrunningaportinRS485signalingmode.When
runningRS485(halfduplex),thethreeswitchesassociatedwiththeportshould
beClosed.Inallothersignalingmodes,theswitchesshouldbeOpen(seetable
belowforport/switchpositionassignments).
NOTE
The use of RS485 requires use of the correct software interface. Consult the driver manual for the
operating system used for details.
Asshippedfromfactory,allswitchesareintheOpenstate.

ThePMC423isaflexiblesolutionforintegratingmultipleserialI/Ochannelsonto
aSingleBoardComputer(SBC).Efficientlypackagingsixteenchannelsontoa
singlePMCmakeseffectiveuseofthefewPMClocationsavailable.RoutingI/O
totherear(viathe‘J4’connectortothehostcard)enhancesflexibilityin
developingeconomical,andnon‐intrusivecablingsolutions.Eachserialportis
implementedwithanindependentUART(AsynchronousReceiverand
Transmitter)withaseparateprogrammablebaudrate.AccessingtheUART
controllersviaPCI,integratesmoreeffectivelytomodernSBCimplementations
thanproprietaryorlegacydevices.
TraditionalUARTcontrollersarelimitedto8‐bitaccess,incurringallbusprotocol
overheadforeverycharactertransferred(andcontroloperations).TheOctal
UARTutilizedonthePMC423supports32‐bittransfers,allowingfourcharacters
tobetransferredinasinglebusoperation.ReducingprogrammedI/Ooperations
iscriticaltoachievinggoodperformanceinPCIsystems.
Whiletheextendedtransferoptionsofferanopportunitytomaximize
performance,inmanycases,thefirst(andsometimesonly)criteriaaresoftware
developmentandintegration.The16C550registersetdefinitionisincommon
usageforserialI/Odevicesinallenvironments.Maintainingcompatibilitywith
thisdefactostandardcanmarkedlyreducethetimerequiredtointegratethe
PMC423intoexistingsoftwareenvironments.Havingthesoftwareintegration
baseduponearlierdrivesreducestheriskofunexpected(andundesirable)
changesinapplicationinterfaces,whichcanbecriticalwhencreatingan
evolutionaryimprovementofexistingsystems.
