The Vecow ME66 is a series of high-performance data acquisition devices with PCIe Interface. They were built for demanding industrial, automation and science applications. The ME66 integrates analog inputs, analog outputs, general purpose digital I/Os, timer/counters and a proprietary inter-system-synchronization-link (ISSL). A fully automated analog calibration circuitry is included as the foundation of high precision and long-term accuracy. Calibration routines can be performed upon user’s request. Despite its low-profile dimensions, rapid data transfer can be achieved, thanks to PCIe bus interface. Scatter-gather DMA engine technology and sophisticate device-driver API help to transfer large data chunks without hassle.
