National Instruments NB-DMA2800 DMA and GPIB Interface Board

The NB-DMA2800 (Part Number: 180785-01) is a 32-bit DMA and GPIB Interface Board. The NB-DMA2800 board was created by National Instruments. The NI NB-DMA2800 board is designed for the Macintosh NuBus computers. This board comes equipped with a high-performance NuBus to GPIB interface, which allows information transfers between the Macintosh computer and numerous IEEE 488-compatible devices. The NB-DMA2800 can be used for integration and optimization of the NB boards’ operations. For this feature, the NB-DMA2800 supports RTSI bus timing and interrupt. The NB-DMA2800 is also compatible with LabVIEW software. The NI NB-DMA2800 board can add a multichannel scanning feature to the DMA interface. The National Instruments NB-DMA2800 board uses PLA technology for this special feature.

The NB-DMA2800 board provides eight 32-bit DMA channels. The NB-DMA2800 comes with an IEEE 488 standard, 24-pin I/O Connector. The NI NB-DMA2800 has board-to-board trigger signal routing hardware. The RTSI switch is a custom-integrated circuit created by NI that interfaces between the RTSI bus and the System Timing Controller unit. This RTSI switch utilizes a crossbar switch to move an input from the counter/timer to one of the seven RTSI bus lines. The NB-DMA2800 can easily transfer data up to 1 Mbytes/s. By interfacing with IEEE 488 instruments, the NB-DMA2800 controller becomes an ideal choice for a various application. These applications include control, monitoring, measurement, and test applications.

The NB-DMA2800 DMA and GPIB Interface Board supports NI-DAQ software for Macintosh. Other compatible software for the NI NB-DMA2800 controller is LabVIEW 2. LabVIEW incorporates interactive graphics, a graphical programming language, and other useful features. The NB-DMA2800 DMA board can be used with NI-488.2 driver software or NI-DAQ software for Macintosh.
