PCI-8330 - NI MXI-3 Interface Board

Description

The PCI 8330 (Part number: 777944-01) is part of the MXI-3 innovation master/slave framework actualizing the PCI-PCI connect enroll set. It couples two physically isolate buses with either a copper or fiber-optic cable equipped for 1.5 Gbit/s serial information rates.  It is possible to utilize MXI-3 to control PCI gadgets on up to 255 buses from any PCI-based framework, as long as the BIOS will support such a setup. The user can utilize either a daisy-chain or a star setup, with the greatest bus-to-bus separation of 10 meters (copper link) or 200 meters (fiber-optic link). Since the MXI-3 framework is a PCI-PCI connect, all gadgets on the framework show up as nearby gadgets in a solitary PCI framework. The user does not have to revamp their gadget drivers for tasks on an MXI-3 framework.   MXI-3 supports and retimes the signals between the buses, keeping up the tight planning and superior PCI requires. The NI PCI 8330 incorporates a setup program for Microsoft Windows working frameworks. The setup program works in a similar way for Windows 2000/NT4/9x. Clients of other working frameworks can disregard this segment. On the opposite side of the framework, the MXI-3 Interface Board gets the information, utilizing rapid photodetectors to change over light signals back to advanced information for the situation where a fiber-optic MXI-3 is utilized. A serial to parallel converter then changes over the advanced serial information to the first 20-bit wide information for the MXI-3 ASIC. MXI-3 then reproduces the PCI exchange with fitting alterations. The device has a maximum of 254 links, a data transfer rate of 132 Mbytes/s at peak performance, and 84 Mbytes per second at sustained performance. The NI device weighs 0.33 lb, and measures 4.2 x 6.9 in. in physical dimensions. It has a recommended operating temperature range of 0 to 50 °C, a storage temperature range of –20 to 70 °C, a non-condensing operating and storage humidity range of 10 to 90% and 5 to 95% respectively.

Analog input module is a device used to collect and process analog signals, which is usually composed of analog input circuit, analog-to-digital converter (ADC), filter and interface circuit. The analog input circuit is responsible for converting the external analog signal into a voltage or current signal, and then converting the analog signal into a digital signal through an analog-to-digital converter, and finally filtering and enhancing the signal through a filter, and finally output to a computer or other control equipment for processing and analysis. Working principle 1. Analog input circuit: The analog input circuit is a key part of the analog input module, which is mainly responsible for converting the external analog signal into a voltage or current signal. Common analog input circuits include resistance divider circuit, current voltage circuit and so on. The resistance divider circuit realizes the signal conversion through the series parallel combination of resistors, and the current voltage circuit realizes the signal conversion through the product of current and resistance. 2. Analog-to-digital converter (ADC) : The analog-to-digital converter is the core component in the analog input module, which is responsible for converting analog signals to digital signals. The analog-to-digital converter discretizes the input voltage or current into a series of digital values according to its magnitude, and converts the continuous analog signal into a discrete digital signal through a process of sampling and quantization. Common analog-to-digital converters include successive approximation analog-to-digital converters and integral analog-to-digital converters. 3. Filter: The filter is an important part of the analog input module, which is mainly used to filter and enhance the signal. The filter can improve the quality and stability of the signal by removing high-frequency noise and interference signals, thus improving the accuracy and reliability of subsequent processing. 4. Interface circuit: The interface circuit is the connection bridge between the analog input module and the computer or other control equipment, which is responsible for converting the digital signal into a form that the computer or other control equipment can recognize and process. Interface circuit usually adopts serial communication interface or parallel communication interface, and realizes data exchange and communication with computer or other control equipment through data line and control line.
