NI serial boards with 2Mbps data rates

Posted: 31 Jan 2005 ?? ?Print Version ?Bookmark and Share


The two new eight-port serial boards from National Instruments (NI) achieve data rates up to 2Mbps and incorporate NI-Mite ASIC technology. According to the company, the PCI-8430/8 and PCI-8431/8 boards improve CPU utilization by 15x compared to traditional plug-in serial interfaces and offer dramatic improvements in speed, reliability and performance compared to native desktop serial ports.

The included NI-Mite ASIC technology delivers DMA memory mapping, PCI bus mastering and scatter-gather technology for superior CPU utilization. Engineers can communicate on all eight ports simultaneously at rates up to 2Mbps with little or no effect on the CPU, freeing up the processor for virtual instrumentation applications that include data acquisition, analysis and presentation. The new boards also offer flexible baud rates to achieve between 57bps and 2Mbps for non-standard rates, and to within 1 percent accuracy and 0.01 percent accuracy for standard rates.

The PCI-8431/8
Expanding NI's PCI-843x family of serial boards to offer simultaneous communication on up to eight RS232, RS485 or RS422 serial ports, both the PCI-8430/8 and PCI-8431/8 are suitable for engineers and scientists wanting to communicate with many instruments or devices simultaneously under test. These new products also include NI-Serial driver software that works with any NI development environment, including LabVIEW, LabWindows/CVI and Measurement Studio for Microsoft Visual Studio.NET.
