National Instruments serial interfaces are 100 percent compatible with standard PC serial ports. NI high-performance PCI serial interfaces (NI PCI-843x) deliver minimal CPU usage with DMA to the PCI bus. They also offer advanced features such as customizable baud rates up to 3,000 kb/s to within 1 percent accuracy, as well as universal PCI, hyperthreading, and multiprocessor compatibility. You can also purchase 2- and 4-port devices with 2,000 V isolation. National Instruments high-performance serial interfaces are available for the same price as NI legacy serial interfaces.
