Overview

Product overview

Key product information and technical features.

This catalog record identifies the four-port PCMCIA-232/4, not the two-port PCMCIA-232/2 also mentioned in the legacy description. NI's archived catalog identifies the four-port model with manufacturer part number 777379-04.

For an existing system, verify the operating system and NI-Serial release before integration. NI's release history explicitly ends PCMCIA-232 and PCMCIA-485 interface support at NI-Serial 3.5.1; a newer driver should not be assumed to support this card.
