1- or 2-Port, USB LIN Interface Device—The USB‑8506 is a Local Interconnect Network (LIN) interface for developing applications with the NI‑XNET driver. The USB‑8506 is powered over the USB bus and does not require external power. The USB‑8506 excels in applications requiring logging or manipulation of hundreds of LIN frames and signals, such as in-vehicle data logging, bus monitoring, automation control, and more. The NI‑XNET device-driven DMA engine enables the onboard processor to move LIN frames and signals between the interface and the user program without CPU interrupts, minimize message latency, and free host processor time. The USB‑8506 is available with a three‑pin COMBICON synchronization connector for triggering and synchronizing the internal hardware timebase with other devices.
