National Instruments PXI-8433/2 PXI Serial Interface Module

The PXI 8433/2 (Part Number: 779744-01) 2 Port, Isolated RS-485/RS-422, Serial Instrument Control Module, is an elite modern interface for fast disengaged communication between ports with RS-485 and RS-422 gadgets. The NI PXI 8433/2 RS-485/RS-422 Interface has Port-PC Isolation and Port-Port Isolation, 2 DB-9 male connectors, 128 Bytes FIFO size, and a 3,000 kbaud maximum baud rate.

According to the NI PXI 8433/2 datasheet, this serial interface has support for superior DMA transfers, multiple threads, and various processors. The user can choose between 4 and 2-wire transceiver modes for medium and full duplex communication. NI serial interfaces are likewise shown as standard COM ports, for compatibility with programs that use serial communications. All NI serial hardware supports standard baud rates. In addition, the NI PXI 8433/2 family of hardware supports any baud rate from 2 baud up to the maximum supported baud rate for that interface. All baud rates are supported because the UART can get within 1.3 percent of all baud rates in that range. The NI device has typical and maximum power requirements of 725 mA and 1 A respectively at +5 VDC. It has operating rated voltages of -25 V to +25 V and -7 V to +12 V for RS-232 and RS-485.

Ground loops, which are current flowing through the ground line when ground voltage levels vary between associated gadgets, are a typical issue in numerous modern applications. On RS-485, this issue brings about a typical mode voltage created by the distinction in ground levels or by noise induced on both lines. Isolating serial ports eliminates this issue and ensures the PC framework in harsh industrial conditions. The device is run using the NI-Serial driver software which is compatible with software packages or application development environments (ADEs) such as LabVIEW or LabWindows/CVI. The National Instruments PXI Serial Interface Modules are accessible with optical isolation up to 2,000 V for such applications.

The PXI-8433/2 weighs 125 g, and measures 6.37 x 3.94 in. in physical dimensions. The module is designed to comply with the following electrical safety standards: IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1.
