Overview

Product overview

Key product information and technical features.

The PCMCIA-485/2 belongs to National Instruments' PCMCIA serial-interface family and provides two RS485 ports. It is distinct from the single-port PCMCIA-485 listed in the same manufacturer catalog.

Software selection requires attention to legacy support. NI's driver release history states that support for PCMCIA-232 and PCMCIA-485 interfaces was discontinued in NI-Serial 3.5.1; a newer NI-Serial release should not be assumed to support this card.

  • Two RS485 serial ports.
  • PCMCIA host-interface format.
  • Explicitly covered by NI's archived Using PCMCIA Serial with Linux configuration note.
