JVM-407B SAE J1939 STX API
7 SAE J1939 STX API
This chapter describes the STX functions of the SAE J1939 STX API.
SAE J1939 is an open standard for networking and communication in the
commercial vehicle sector. The focal point of the application is the networking
of the power train and chassis. The J1939 protocol originates from the
international Society of Automotive Engineers (SAE) and works on the
physical layer with CAN high-speed according to ISO 11898.
These STX functions are used in communication between the controller
JVM-407B and other ECUs in the vehicle. As a rule, engine data, such as
RPM, speed or coolant temperature are read and displayed.
The key SAE J1939 specifications are:
 J1939-11 - Information on the physical layer
 J1939-21 - Information on the data link layer
 J1939-71 - Information on the application layer vehicles

J1939-73 - Information on the application layer range analysis
 J1939-81 - Network management
