Overview

Product overview

Key product information and technical features.

The NI-9866 brings LIN bus communication into the NI C Series ecosystem. NI identifies hardware-in-the-loop simulation, rapid control prototyping, bus monitoring, and automation control as relevant applications.

System integration requires a supported chassis and software combination. Consult the NI-XNET release documentation for the intended host platform rather than assuming support across every CompactDAQ or CompactRIO system.

  • Single-port LIN interface using the NI-XNET driver.
  • LIN port isolated from other system modules.
  • Software-selectable LIN master termination.
  • Supports external timing and triggering.
