SAE J1939
What is SAE J1939?
SAE J1939 is a communication standard built on the CAN bus that defines how electronic components exchange data in heavy-duty on-road and off-road vehicles, including trucks, buses, construction equipment, and agricultural machinery. It standardizes how engine performance, transmission status, and diagnostic information are formatted and shared across the network. Because AMETEK VIS specializes in heavy-vehicle instrumentation, its CAN-based gauges and displays are engineered to operate within J1939 networks. Protocol support varies by product, so compatibility should always be confirmed using the individual product datasheet.
