The JCOM1939 Monitor Software is the perfect tool for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. It works in combination with our SAE J1939 gateways.
This comprehensive and easy-to-use, easy-to-understand Windows software displays not only SAE J1939 data traffic but also allows scanning the network, simulating an ECU (incl. full node address negotiation features), and responding to data request messages.
The communication protocol between the gateway and the host system (PC, Embedded System, Android System, etc.) is well documented, and we provide C/C# source code to read and write CAN data frames.

Required Hardware
The JCOM1939 Monitor Software for Windows works in combination with the following SAE J1939 gateways:
SAE J1939 Starter Kit and Network Simulator
The starter kit allows you to monitor, simulate, and record any PGN as defined in the SAE J1939-71 Standard, including diagnostic messages according to SAE J1939-73. Many users ask us whether or not we can process specific parameters such as fuel consumption, vehicle speed, vehicle position, etc., and the answer is always yes. However, you need to understand that the starter kit was not designed for specific engine parameters, i.e., you need to know which PGN represents the desired data. Also, the starter kit was not designed to simulate particular diesel engines, but if you enter all PGNs that are being used, you can create and simulate any diesel engine. More Information…
SAE J1939 ECU Simulator Board with USB Port
The gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network.
The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including complete C/C++/C# source code for short time-to-market developments.
The board’s strength lies in the fact that the entire SAE J1939 protocol, including all timing requirements, is stored on-chip, thus taking the burden off the primary system. The board uses a USB COM port to communicate with the primary system, i.e., all data transfer is handled through a standard COM port access. More Information…
Development & Prototyping for Classic CAN, CAN FD, SAE J1939, NMEA 2000
Copperhill Technologies, a Massachusetts corporation, was established as an electronics engineering and consulting business with the main focus on the development, prototyping, and sales of embedded systems for Controller Area Network (Classic CAN, CAN FD), SAE J1939, and NMEA 2000, which includes popular systems such as the Arduino and Raspberry Pi but also our embedded solutions based on the ESP32 microcontroller.
The skills of our hardware and software engineering team include rapid prototyping; we can deliver prototype solutions within the shortest time and assist with the manufacturing process of the final product. We provide not only schematics, bill of material, placement files, Eagle/Gerber files but also the application source code including documentation.
