Description
The NI PCI-8430/2 Serial Interface, with Part Number 778978-01, is a two-port solution for RS232 communication, featuring more than eighty RS232 lines for extensive connectivity options. This interface ensures operational consistency by prohibiting memory changes during instrument use through its Framework Access feature.
It also includes a Cycle Power functionality that allows for a full system shutdown or complete energy removal for safety and maintenance procedures. The support for hyper-threading and multiprocessor capabilities enables users to leverage advanced PC technologies for enhanced speed and performance.
The included driver software provides improved resource allocation and DMA access, optimizing throughput while minimizing CPU usage. To avoid I/O resource conflicts, the device employs memory mapping, and it offers compatibility with both 3.3 and 5 V PCI slots.
Integration with development environments is seamless thanks to compatibility with the NI-Serial device driver that works in conjunction with NI-VISA, as well as LabVIEW Real-Time compatibility for deterministic control through Plug-In and ENET solutions. Additionally, the module offers optical isolation up to 2000 V, increasing system protection against electrical interference.
Despite the announcement of its Mature Status by National Instruments, the NI PCI-8430/2 remains available for purchase and repairs, ensuring long-term usability and support for existing systems.
