Key product information and technical features.
This legacy PCI-232 family board provides four RS-232 ports. Its 10-position modular connections require conversion cables for DB-9 or DB-25 male connections.
Check the host software environment before integration: NI-Serial 17.0 removed support for PCI-232 interfaces. Verify an earlier driver's hardware and operating-system support rather than assuming a current driver will work.
