National Instruments PXI-8433/4 PXI Serial Interface Module

The PXI-8433/4 (Part Number: 779539-01, ) 4 Port, Isolated, RS-485/RS-422, Serial Interface Module is an asynchronous interface for communicating with instruments by means of serial ports. Depending on the platform, interfaces are accessible with as many as 16 ports and full Windows 2000/NT/XP/Me/9x plug-and-play compatibility, which gives the user the advantage of programmed setup for less demanding establishment and maintenance. The user can introduce and utilize these gadgets as standard serial ports from their current applications or with applications composed with NI-VISA.

Development environments, such as Visual Basic, Visual C++, and Excel, along with NI LabVIEW, LabWindows/CVI, Measurement Studio, and Lookout application programming items, can access the add-in serial ports by utilizing standard serial I/O capacities. The NI PXI 8433/4 incorporates an upgraded serial driver for enhanced execution, simple design, and access to the advanced transceiver control modes of the RS-485 interface.

The 4-port interface utilizes 10-position phone jacks, so each of the four connectors can exist on a single back panel. When purchasing a 4-port serial interface, the user can arrange links that change over the phone jacks to either DB-9 or DB-25 male connectors with standard pin assignments. In general, the user should arrange four converter links for each 4-port serial gadget. Note that a converter link is not intended to go the full distance from a 4-port serial interface specifically to the instruments. The most popular converter cables change over the 10-pin phone jack on a 4-port gadget to a similar DB-9 male connector, which can be found on a normal PC serial port. The association from this converter to the serial gadget uses the standard links utilized with the PC serial port.

The NI device weighs 147 g, and measures 6.3 x 3.9 in. in physical dimensions. It has a recommended operating temperature range of 0 to 55 °C, a storage temperature range of –40 to 70 °C, an operating and storage humidity range of 10% to 90% and 5% to 95% respectively, and an operating and non-operating random vibration of 0.3 grms and 2.4 grms respectively–all at a frequency range of 5 to 500 Hz.
