高速32通道數(shù)字量輸入輸出板卡

主要特點 主要特點 總線控制DMA數(shù)據(jù)傳輸，支持satter/gather技術(shù) 32/16/8位模式I/O處理，帶啟/停觸發(fā)功能，2個模式握手I/O中斷處理能力 板載主動終端電阻，高速和遠(yuǎn)程傳輸 支持模式匹配和狀態(tài)改變檢測中斷功能 通用8通道數(shù)字量I/O

The PCI-1755 supports PCI-bus mastering DMA for high-speed data transfer. By setting aside a block of memory in the PC, the PCI-1755 perbs bus-mastering data transfers without CPU intervention, setting the CPU free to perb other more urgent tasks such as data analysis and graphic manipulation. The function allows users to run all I/O functions simultaneously at full speed without losing data.
