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 Vsup with a 30 k
Ω
resistance and a serial diode. This
termination usually is integrated into the transceiver package. The
master node requires a 1 k
Ω
resistor and serial diode between the
LIN bus and Vsup. 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-XNET LIN Transceiver Cable Hardware
Overview
The NI-XNET LIN Transceiver Cable has one full-featured LIN
port that is isolated from the host it is plugged into. The port has an
NXP TJA1028 LIN transceiver that is fully compatible with the
LIN 1.3/2.0/2.1/2.2 and SAE J2602 standards and supports baud
rates up to 20 kbps.
