National Instruments PCIe-8430/2 Serial Interface Device
The National Instruments PCIe-8430/2 (Part number: 782122-01) is a 2-Port, PCI Express based Serial Interface Device that supports RS232 serial communications. This model is the perfect answer for efficient communications between a PCIe enabled PC and different RS232 devices. The National Instruments PCIe-8430/2 device has some powerful features, such as DMA transfers, multiprocessor support, and multithreading. The DMA transfer scheme allows the I/O device to transmit data to or from the main memory, while keeping the CPU out of the loop. This configuration brings much faster memory operations and is controlled by a chip called a DMA controller or DMAC. The ability to work in multi-processor or multithreading environments allows the NI PCIe-8430/2 to have its resources used at an optimum level.
This RS-232 Serial Interface Device requires one PCI Express slot, which the device turns into two RS-232 (or DB-9) serial connections since it comes with two DB-9 connectors. The NI PCIe-8430/2 RS-232 Serial Interface Device draws 325 mA of current (typical) or 500 mA (maximum) at +5 VDC. This model offers from 2 baud minimum to 1000.0 kbaud maximum baud rate. This device comes with a 128 byte FIFO as well. This device supports the following types of settings: adjustable FIFO settings, Get Interface, RS-232 Transceiver State, RTS/CTS, DTR/DSR, and Xon/Xoff settings. The National Instruments PCIe-8430/2 device is offered in the standard PCIe form factor. This RS-232 Serial Interface Device weighs around 88 g and has 10.67 × 14.22 cm physical dimensions.
