National Instruments AT-MXI MXIbus ISA Interface Card
* Serial Number: Quantity Available
* Supports 32-Bit (A32), 24-Bit (A24) and 16-Bit (A16) Addressing
* Supports Both 16-Bit (D16) and 8-Bit (D08) Data Transfers
* Conforms to ISA Specifications
* Conforms to the MXIbus Specification
* The AT-MXI can function as both a MXIbus master and a MXIbus salve. When operating as a MXIbus master, the AT-MXI converts PC AT memory cycles initiated by the CPU or an alternate but master on the PC AT bus into MXIbus cycles intended for a MXIbus slave device. When operating as a MXIbus salve, the AT-MXI converts MXIbus cycles initiated by a MXIbus master into PC AT memory or I/O bus cycles so that other MXIbus devices can freely access (share) resources within the PC AT.
* As a MXIbus master, the AT-MXI supports 32-bit (A32), 24-bit (A24) and 16-bit (A16) addressing. As a MXIbus slave, the AT-MXI communication registers and to the OC AT I/O space. The AT-MXI supports both 16-bit (D16) and 8-bit (D08) data transfers while operating as either a MXIbus master or MXIbus slave. The AT-MXI cannot support 32-bit (D32) data transfers because the PC AT data bus is only 16 bits wide.
* Because the AT-MXI uses the same communication register set that is used by VXIbus Message-Based devices, other MXIbus devices can view the AT-MXI as a VXIbus device. The AT-MXI supports MXIbus block-mode transfers, data located in consecutive memory locations can be transferred at higher rates because MXIbus addressing information is not sent with each data transfer. The AT-MXI supports the use of the direct memory access (DMA) controller on the PCT AT computer when transferring block-mode data between the PC AT bus and the MXIbus. Optionally, any MXIbus or PC AT bus master can be used to initiate and transfer block-mode data via the AT-MXI.
