The National Instruments PCI-8430/2 (Part Number: 778978-01) is a high-performance RS232 serial interface card designed for reliable communication with RS232 devices. Featuring two ports and supporting data rates of up to 1 Mbps, this device provides efficient connectivity in demanding applications. The PCI-8430/2 integrates alignment constants stored in EEPROMs, which optimize the device's operational range without retaining unique settings unless specified. Its robust architecture includes over eighty slots for enhanced performance and a unique Framework Access function that maintains memory integrity during standard operations, enabling users to efficiently manage RAM data. Additionally, the card is equipped with Cycle Power functionality, facilitating complete shutdowns for device maintenance.

Enhanced with hyper-threading and multiprocessor support, the PCI-8430/2 is engineered to leverage modern computing capabilities for improved speed and performance. The latest driver software included with the device ensures streamlined resource detection and DMA access while minimizing CPU load. Compatibility is assured with a memory-mapped I/O to avoid resource conflicts, and it operates seamlessly with both 3.3 and 5 V PCI slots. The NI-Serial driver works in conjunction with NI-VISA, allowing straightforward development and compatibility with LabVIEW Real-Time applications for deterministic control. With optical isolation up to 2000 V, this interface enhances reliability in various settings. The PCI-8430/2 is classified under Mature Status by National Instruments, yet remains available for purchase and support through Apex Waves. For detailed specifications, the user and maintenance manuals are available for download, and interested customers should contact a sales representative for pricing information.
