Vehicle Multiprotocol Interface

Vehicle Multiprotocol Interface provides a hardware-selectable controller area network (CAN) and/or local interconnect network (LIN) interface for developing applications with the NI-XNET driver on CompactDAQ or CompactRIO.

It also uses hardware-selectable NI-XNET Transceiver Cables (TRC) to communicate High-Speed/Flexible Data‑rate CAN, Low-Speed/Fault/Tolerant CAN, and/or LIN. Vehicle Multiprotocol Interface Modules work well in applications such as hardware-in-the-loop (HIL) simulation, rapid control prototyping, bus monitoring, and automation control.
