Description
The National Instruments VXI-MXI-2/B VXIbus Extender is a B-size extender designed for extended class mainframes and is a product of National Instruments, a leading manufacturer in the field. It utilizes the MXI-2 bus architecture, which is the second generation of MXIbus, providing compatibility with a range of devices including MXIbus instruments, PCs with MXIbus, and other VXIbus mainframes.
This extender employs an advanced address mapping technique to interface the VXIbus system bus with the MXIbus, making it a crucial register-based VXIbus module for extending system architectures. Furthermore, the VXI-MXI-2/B is capable of converting a variety of bus cycles, such as A16, A24, A32, D08, D16, D32, and D64, ensuring versatility in its applications.
Equipped with four address windows, the extender offers efficient mapping into and out of the VXIbus mainframe. Its capability to support the VME RETRY signal is essential for resolving deadlock conditions, enhancing system reliability. Additionally, the inclusion of two independent DMA controllers enables efficient data transfers, further demonstrating the extender’s multifunctional attributes.
Despite its obsolete status being announced by National Instruments, the VXI-MXI-2/B VXIbus Extender remains accessible for purchase and can undergo repairs through Apex Waves, providing ongoing support for users of this critical piece of equipment.
