For engineers, developers, and automotive enthusiasts working with the SAE J1939 vehicle network, Copperhill Technologies offers two cutting-edge solutions that provide seamless connectivity between J1939 networks and USB-enabled devices. These products—the SAE J1939 to USB Gateway with Plastic Enclosure and the SAE J1939 ECU Simulator Board with USB Port—offer identical functionality, differing only in their physical construction. Whether you require a rugged, enclosed unit for durability or a bareboard option for easy integration and customization, Copperhill Technologies has you covered.

SAE J1939 to USB Gateway with Plastic Enclosure

The SAE J1939 to USB Gateway in Plastic Enclosure is designed for professionals who need a robust, plug-and-play solution for interfacing with J1939 networks. The plastic enclosure provides added protection, making this unit ideal for industrial environments, field applications, and long-term use.

Key Features:

• Durable and Protective Housing – The plastic enclosure safeguards the electronics from dust, debris, and minor impacts, ensuring longevity and reliable operation.

• Plug-and-Play Functionality – Seamlessly connects J1939 networks to a PC or laptop via USB, requiring minimal setup.

• Supports Standard SAE J1939 Protocols – Ideal for fleet diagnostics, vehicle network analysis, and embedded system development.

• User-Friendly Software Interface – Comes with intuitive software tools for monitoring, logging, and analyzing J1939 data.

• JCOM1939 Monitor Software Included – Provides real-time message monitoring, data logging, and message transmission, enhancing diagnostic and development capabilities.

• Reliable Data Transfer – Ensures stable communication between your J1939 network and USB-enabled device.

This enclosed version is the perfect choice for those working in environments where protection from physical elements is necessary. Whether in a workshop, on the field, or within an automotive testing facility, the enclosure ensures optimal performance without the risk of damage to delicate components.

SAE J1939 ECU Simulator Board with USB Port (Without Enclosure)

For developers and engineers who prefer a more customizable approach, the SAE J1939 ECU Simulator Board with USB Port offers the same high-quality functionality as its enclosed counterpart but without the protective casing. This makes it an excellent option for those looking to integrate the device into a larger system or embed it within their own enclosure.

Key Features:

• Compact, Open-Board Design – Ideal for developers who need direct access to the board’s components for modification or integration.

• Full SAE J1939 Support – Perfect for simulating ECUs, testing network configurations, and troubleshooting vehicle systems.

• USB Connectivity for Seamless Integration – Quickly interfaces with a computer to send and receive J1939 messages.

• JCOM1939 Monitor Software Included – Provides advanced functionalities such as message filtering, timestamped logging, and customizable message transmission.

• Cost-Effective Solution – The absence of an enclosure makes this version more budget-friendly while maintaining the same advanced features.

• Ideal for Prototyping and Custom Builds – Can be incorporated into specialized projects requiring unique enclosures or mounting configurations.

The bareboard version is particularly useful for engineers who are developing their own enclosures or integrating the device into a larger system. If you are comfortable working with exposed circuit boards and require more flexibility, this version is an excellent choice.

Which Version is Right for You?

Both the enclosed and open-board versions of the SAE J1939 to USB Gateway offer the same powerful capabilities for interfacing with J1939 vehicle networks. Choosing between them depends on your specific needs:

• For rugged environments and ease of use, the SAE J1939 to USB Gateway with Plastic Enclosure is the ideal solution.

• For custom integrations, prototyping, and cost-conscious projects, the SAE J1939 ECU Simulator Board with USB Port is a great alternative.

No matter which version you choose, you can rely on Copperhill Technologies to provide a high-quality, reliable solution for all your SAE J1939 connectivity needs. Both versions come with the JCOM1939 Monitor Software, a powerful tool for real-time data monitoring, logging, and message transmission, making these products indispensable for developers, fleet managers, and automotive engineers.
