NI 9866 Hardware Overview

The NI-9866 has one full-featured LIN port that is isolated from the other modules in

the system. The port has a LIN controller that is fully compliant with the LIN

1.3/2.0/2.1/2.2 Specification. The port also has an NXP TJA1028 LIN transceiver that

is fully compatible with the LIN 1.3/2.0/2.1/2.2 and SAE J2602 standard and supports

baud rates up to 20 kbps.
