AllPXIserialhardwareusesstandard16550-compatibleUARTs
(UniversalAsynchronousReceiver/Transmitters)forcomplete
compatibilitywithstandardPCCOMports.Theserialhardwarecontains
FIFO(First-In-First-Out)bufferstoreducesusceptibilitytointerrupt
latencyforfastertransmissionrates.FullPlugandPlaycompatibility
allowsswitchlessconfigurationandinstallation.Formoreinformation
abouttheserialhardwarespecificationsandoperatingconditions,referto
theNISerialHardwareGuide.
