NI / EMERSON 866576-05

866576-05 is a 2-port, high-speed/FD, vehicle networks module. The vehicle networks module is a high-speed controller area network (CAN) interface for developing applications with the NI‑XNET driver. This module is powered over the USB bus and it does not require external power. User can use the Vehicle Network module in applications that require real-time, high-speed manipulation of hundreds of CAN frames and signals such as bus monitoring, automation control, and more. The NI‑XNET device‑driven direct-memory-access (DMA) engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimizing message latency and freeing host processor time for processing complex applications. Additionally, the Vehicle Networks Module is available with a three‑pin COMBICON synchronization connector for triggering and synchronizing the internal hardware timebase with other devices.
