PCI-1755
80 MB/s, 32-ch Digital I/O PCI Card
Features
 Bus-mastering DMA data transfer with scatter gather technology
 32/16/8-bit Pattern I/O with start and stop trigger function, 2 modes
Handshaking I/O Interrupt handling capability
 Onboard active terminators for high speed and long distance transfer
 Pattern match and Change state detection interrupt function
 General-purpose 8-ch DI/O
Introduction
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 performs bus-mastering data transfers
without CPU intervention, setting the CPU free to perform other more urgent tasks such as data analysis and graphic manipulation. The function allows users to run all I/O unctions
simultaneously at full speed without losing data.
