Product Code:SAE J1939/14
Title:Physical Layer, 500 Kbps
Issuing Committee:Truck Bus Control And Communications Network Committee
Scope:This document defines a physical layer having a higher bandwidth capacity than other physical layers defined for SAE J1939. Newer transceiver technologies are utilized to minimize EMI.This SAE Recommended Practice is intended for light- and heavy-duty vehicles on- or off-road as well as appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicles of interest include but are not limited to: on- and off-highway trucks and their trailers; construction equipment; and agricultural equipment and implements.
