Termination Resistors
LIN cables require no termination, as nodes are terminated at the
transceiver. Slave nodes typically are pulled up from the LIN bus
to VBat with a 30 kΩ resistance and a serial diode. This
termination usually is integrated into the transceiver package.
The master node requires a 1 kΩ resistor and serial diode
between the LIN bus and VBat. On NI-XNET LIN products,
master termination is software selectable; you can enable it in the
API with the NI-XNET Session Interface:LIN:Termination
property.
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.
