NBN ISO/TS 21815-2:2022

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).
This document is not intended for plug-and-play implementation of CAS or CWS on the machine.
Additional details not fully described in this document can be negotiated by the CAS or CWS
manufacturer and the machine manufacturer to enable functionality.
This document does not preclude the possibility of the machine manufacturer or the CxD manufacturer
developing alternative on-board communication interfaces.
