This document describes the on-board J1939 communication interface between a connected device and mobile machines for use in earth-moving, mining and road construction applications to enable interventional collision avoidance actions defined in ISO 21815-1 based on the SAE J1939 protocol. This interface is intended for use by a collision avoidance system (CAS) device integrated independently from the original machine providing intervention signals to slow down, stop or prevent motion of the machine. The protocol defined by this document can also be used to provide input information for a collision warning system (CWS).
