National Instruments PXI-8430/16 RS-232 Interface

The PXI-8430/16 (Part Number: 779948-01) RS-232 Interface includes elite DMA exchanges, multithreading, and multiprocessor bolster. Not at all like customary interfere based serial interfaces, the user can utilize different serial interfaces to communicate with many ports at high rates easily in a solitary framework with negligible CPU use. The included NI-VISA API streamlines serial programming in NI LabVIEW and different languages and keeps the code compact between all VISA-good interfaces. The NI PXI-8430/16 RS-232 Interface appear as standard COM ports for similarity with programs that use serial interchanges. Rapid digitizers like this ordinarily have built-in memory to suit tests. Be that as it may, now and then the circumstance emerges where the information to be examined is more than the accessible memory. In these circumstances, it is critical to see how the digitizers utilize the DMA, to exchange the information between the card and the PC. The digitizers utilize the NI-SCOPE controllers and the DMA to exchange the samples from the card to the PC through the PCI interface. When calling the "Bring" work, the information exchange between the card and the visitor PC is begun. "Bringing" the examples alludes to the way toward exchanging the signal procured by the digitizer, which is in memory to the PC. This is finished utilizing the "DMA".

This model is compatible with Windows 7/Vista/XP/2000, LabVIEW Real-Time. The PXI-8430/16 has flexible standard and nonstandard baud rates from 2 bauds to 1,000,000 bauds and more than 0.015 percent precision for standard baud rates and 0.5 percent for nonstandard rates, a high-speed DMA interface, and 128 B FIFO size. The serial interface module is equipped with 16 ports, and has 2 68-position VHDCI I/O connectors. It has a power requirement of +5 VDC at 935 mA typical and 1.4 A maximum.

The NI device weighs 157 g, and measures 3.94 x 6.37 in. in physical dimensions. It has a recommended operating temperature range of 0 to 55 °C, and a storage temperature range of –20 to 70 °C.

PXI-8430/16 Mature Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
