National Instruments PCIe-8430/8 RS232 Serial Interface Device
Designed for high-speed RS-232 communications, the National Instruments PCIe-8430/8 (Part Number: 780591-01) is a PCI Express based Serial Interface Device. This model can be used as a standard COM port; thus, it supports a broad range of serial communication programs. The NI PCIe-8430/8 comes with 8 non-isolated ports. In addition, this model offers 1000.0 kbaud Max Baud rate and it comes equipped with 128 bytes FIFO.
The NI PCIe-8430/8 (RS232) is built in compliance with the standards mentioned by the PCI Express Serial Hardware. This model has physical dimensions of 11.12 × 17.53 cm. The user can have their PCIe-8430/8 deployed in any unoccupied PCI Express slot. In its standard configuration and while operating within the temperature ranges as defined by National Instruments, this Serial Interface Device will draw 200 mA (typical) or 750 mA (maximum) current from +3.3 VDC rail and 190 mA (typical) or 220 mA (maximum) current from +12 VDC. This model does not have a supported power input and additionally does not have isolation.
The National Instruments PCIe-8430/8 RS-232 Serial Interface Device requires no configuration since all of the device resources are assigned automatically. This RS232 Serial Interface Device supports multithreading, multiprocessors, and DMA transfers as well. Moreover, this device is also compatible with dual processor host machines. Thus, it can bring higher transfer rates and better overall efficiency at an affordable cost. For PCI Express to RS232 connectivity, the National Instruments PCIe-8430/8 device features one 68-pin VHDCI port.
