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 .
The following table lists the PXI serial board numbers and corresponding
