Overview

Product overview

Key product information and technical features.

The PCI-8430/2 adds two RS-232 serial ports to a PCI-based host. NI lists this model separately from PCI Express and PXI serial interfaces; those platform names should not be treated as interchangeable.

Within the PCI-8430 family, the /2 model provides two ports. NI also documents four-, eight-, and sixteen-port versions, allowing comparison by port count without confusing RS-232 models with RS-485/RS-422 interfaces.

  • Two RS-232 serial ports on a PCI interface.
  • Maximum supported baud rate of 1000 kbaud.
  • DB-9 male serial connections.
  • 128-byte FIFO listed in NI's serial hardware specifications.
