原廠英文說明
The National Instruments PXI-8430 RS-232 High-Performance, Multi-Port Serial Interfaces is used for high-speed communication with RS232 devices at rates of up to 1 Mbit/s. High-performance RS232 interfaces are also available with two ports. The PXI-8430 offers flexible baud rates for data transmissions between 57 baud and 1,000,000 baud to within 1 percent accuracy for nonstandard baud rates and 0.01 percent accuracy for standard baud rates.With the high-performance DMA engine, you achieve high throughput with minimal CPU usage. Using memory mapping, you can connect to more communication points without resource conflicts. National Instruments also offers easy-to-use powerful software that significantly reduces your development time for systems using serial communication with the PXI-8430.
