Under circumstances that Windows OS is moving from 32bit to 64bit, there had been restriction that only 1MB buffer memory in PC with 64 bit OS could be used for data transfer and this unique DMA transfer function could not be utilized adequately due to the specification of OS. DIO-32DM3-PE retains upward compatibility as a successor to the conventional product (model: DIO-32DM2-PE) and features a maximum sampling rate that has been improved by 2.5x. Through improvements in PCI Express control logic, the bus master transfer rate has been increased by 4.5x, while the memory space that can be used for transfers has been dramatically expanded by 32x for 32 bit OS and by 2,048x for 64 bit OS.
