Title:Class B Data Communications Network Interface
Issuing Committee:Vehicle Architecture For Data Communications Standards
Scope:This SAE Standard establishes the requirements for a Class B Data Communication Network Interface applicable to all On- and Off-Road Land-Based Vehicles. It defines a minimum set of data communication requirements such that the resulting network is cost effective for simple applications and flexible enough to use in complex applications. Taken in total, the requirements contained in this document specify a data communications network that satisfies the needs of automotive manufacturers.This specification describes two specific implementations of the network, based on media/Physical Layer differences. One Physical Layer is optimized for a data rate of 10.4 Kbps while the other Physical Layer is optimized for a data rate of 41.6 Kbps (see Appendix A for a checklist of application-specific features). The Physical Layer parameters are specified as they would be detected on the network media, not within any particular module or integrated circuit implementation.Although devices may be constructed that can be configured to operate in either of the two primary implementations defined herein, it is expected that most manufacturers will focus specifically on either the 10.4 Kbps implementation or the 41.6 Kbps implementation depending on their specific application and corporate philosophy toward network usage. However, low-volume users of network-interface devices are expected to find it more effective to use a generic interface capable of handling either of the primary implementations specified in this document.Product Code:SAE J2222
Title:Coiled Electrical Cable - Truck and Bus
Issuing Committee:Truck And Bus Electrical Systems Committee
Scope: This SAE Standard establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers and dollies. The component standards SAE J2394 (replaced SAE J1067) for cable and SAE J560 for connectors must be consulted to determine the complete performance and endurance requirements of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation and inspection of these coiled electrical cables. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.
