SAE J1939 Starter Kit and Network Simulator

Our JCOM.J1939 Starter Kit and Network Simulator are designed to allow experienced engineers and beginners to experiment with SAE J1939 data communication without needing to connect to a real-world J1939 network, i.e., a diesel engine. 

To establish a network, you need at least two nodes. This applies especially to CAN/J1939, where the CAN controller will shut down after transmitting data without receiving a response. Therefore, our jCOM.J1939 Starter Kit and Network Simulator consist of two J1939 nodes: our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board with USB Port. More Information...
