GLOSSARY OF VEHICLE NETWORKS FOR MULTIPLEXING AND DATA COMMUNICATIONS

1991-06-01
HISTORICAL
J1213/1_199106
This SAE Information Report provides definition for terms (words and phrases) which are generally used within the SAE in describing network and data communication issues. In many cases, these definitions are different from those of the same or similar terms found in nonautomotive organizations, such as the Institute of Electrical and Electronic Engineers (IEEE). The Vehicle Networks for Multiplexing and Data Communications committee has found it useful to collect these specific terms and definitions into this document so documents related to the multiplexing and data communications issues will not need an extensive definitions section. This document is intended to be the central reference for terms and definitions related to multiplexing and data communications and as such is intended to apply equally to Passenger Car, Truck and Bus, and Construction and Agriculture organizations within SAE.

HISTORICAL
J2057/2_200108
The Class A Task Force of the Vehicle Network for Multiplex and Data Communications Committee is publishing this SAE Information Report to provide insight into Class A Multiplexing. Multiplexed actuators are generally defined as devices which accept information from the multiplexed bus. A multiplexed actuator can be an output device controlled by the operator or an intelligent controller. A Multiplex actuator can also be a display device that reports the status of a monitored vehicle function. This document is intended to help the network system engineers and is meant to stimulate the design thought process. A list of multiplexed actuator examples is provided in Appendix A, Figure A1. Many other examples can be it identified.

J2057/3_200108
The Class A Task Force of the Vehicle Network for Multiplexing and Data Communications Subcommittee is providing information on sensors that could be applicable for a Class A Bus application. Sensors are generally defined as any device that inputs information onto the bus. Sensors can be an input controlled by the operator or an input that provides the feedback or status of a monitored vehicle function. Although there is a list of sensors provided, this list is not all-inclusive. This SAE Information Report is intended to help the network system engineer and is meant to stimulate the design thought process.

HISTORICAL
J2178/2_199306
This SAE Recommended Practice defines the information contained in the header and data fields of non-diagnostic messages for automotive serial communications based on SAE J1850 Class B networks. This document describes and specifies the header fields, data fields, field sizes, scaling, representations, and data positions used within messages. The general structure of a SAE J1850 message frame without in-frame response is shown in Figure 1. The structure of a SAE J1850 message with in-frame response is shown in Figure 2. Figures 1 and 2 also show the scope of frame fields defined by this document for non-diagnostic messages. Refer to SAE J1979 for specifications of emissions-related diagnostic message header and data fields. Refer to SAE J2190 for the definition of other diagnostic data fields. The description of the network interface hardware, basic protocol definition, the electrical specifications, and the CRC byte are given in SAE J1850.
