Product Code:SAE J2178/1
Title:Class B Data Communication Network Messages - Detailed Header Formats and Physical Address Assignments (STABILIZED Apr 2011)
Issuing Committee:Vehicle Architecture For Data Communications Standards
Scope: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.SAE J1850 defines two and only two formats of message headers. They are the Single Byte header format and the Consolidated header format. The Consolidated header format has two forms, a Single Byte form and a three byte form. This document covers all of these formats and forms to identify the contents of messages which could be sent on a SAE J1850 network.This document consists of four parts, each published separately.MIL-PRF-24667B (SH), PERFORMANCE SPECIFICATION, COATING SYSTEM, NON-SKID, FOR ROLL OR SPRAY APPLICATION (3 JUN 2005), This specification covers non-skid coating systems for application to weather decks, flight decks, and hangar decks of air capable amphibious aviation and aviation ships. Coatings are applied to steel, aluminum, reinforced plastic and special hull treatment (SHT) surfaces by spraying or rolling, or other application method as designated by the non-skid coating manufacturer.
