I want to reiterate a point made in a previous post ("A Beginner's Guide to SAE J1939 Embedded Software Development"): When developing and testing your CAN Bus application, may it be Classical CAN, CAN FD, CANopen, SAE J1939, or NMEA 2000, you need to connect your device to a functional network. One solitary node connected to your device will not do. On the other hand, a working network provides operation under stable conditions, i.e., the assurance that any possible communication problems have to do with your device (no pun intended; that's just in the nature of things).
Our Starter Kit and Network Simulator provides a solution for SAE J1939 testing but also ISOBUS and (to a certain degree) NMEA 2000. However, when vigorously testing new devices and their firmware, I add another device, a CAN analyzer that displays all CAN Bus traffic regardless of the protocol used. In the past, I used the ADFWeb.com USB-to-CAN converter. Their Windows software is easy to manage, which is crucial since I don't particularly appreciate going through significant learning curves.
Many such USB gateways are available in the market, and they vary in complexity and pricing. The top-of-the-line will be suitable if you are engaged in complex CAN Bus development, such as automobile or robotics applications. However, when it comes to SAE J1939 or NMEA 2000, there is no need for all top-notch features (e.g., sample point timing, oscillator frequency, etc.).
When it was time to modernize my test hardware to Windows 11 (with all its nasty USB driver restrictions), I also updated the CAN Analyzer hardware. I opted for the PEAK PCAN-USB Pro, which supports two CAN and LIN Bus interfaces. As I mentioned, simple yet effective Windows software is essential to me, and PCAN-View does not disappoint. Setup was a breeze (besides the fact that Windows 11 does not recognize their USB port), and the software was created with great user-friendliness in mind, making reading the user manual an optional task.
The screenshot above demonstrates the data traffic between two devices, the PCAN-USB Pro and our SAE J1939 Simulator Board, which are connected through our CAN Bus Hub board (see test setup on top of the page). When testing new devices and firmware versions, I connect to the hub with the knowledge that any discrepancy must be originated in the new device, thus preventing any time-consuming shooting-in-the-dark scenario.
SAE J1939 to USB Gateway in Plastic Enclosure
The SAE J1939 to USB Gateway utilizes our SAE J1939 ECU Simulator Board With USB Port and embeds it in an enclosure. The SAE J1939 gateway allows you to monitor, simulate, and record any PGN as defined in the SAE J1939-71 Standard but also including diagnostic messages according to SAE J1939-73.
The gateway 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 full C/C++/C# source code for short time-to-market developments.

The Six-Channel PCAN-Router Pro FD by PEAK Systems connects the data traffic of modern CAN FD and classic CAN Bus networks. Pluggable CAN Bus transceiver modules provide universal adaptation for each CAN-Bus channel to match their individual requirements. In addition, the router comes with an analog input and four digital I/Os. The CAN Bus data traffic can [...]
To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]
Warwick Control Technologies has released a development kit that enables users to simulate Classical CAN, CAN FD, and LIN devices and networks. It also supports the simulation of SAE J1939, NMEA 2000, and CANopen devices and networks. The kit comes with the Kvaser Hybrid Pro two-channel interface to test Classical CAN, CAN FD, and LIN systems through [...]
HMS Networks introduced the IXXAT CANnector solution for logging, bridging, and extending Classical CAN Bus and CAN FD networks. The device complements and is compatible with the existing CAN@net NT and CANbridge NT series. Three pre-configured versions are available in addition to a generic stand-alone device (no PC is needed). The CANnector supports the transmission of CAN/CAN [...]
Vector Informatik released its VN5620 network gateway for Automotive Ethernet and Classical CAN, as well as CAN FD networks. The two CAN FD interfaces utilize the TJA1057 transceivers from NXP.The device is suitable for data analysis, simulation, and testing tasks. The data monitoring per Ethernet warrants a transparent connection between two nodes with a precise timestamp. [...]
The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee has developed a family of standards concerning the design and use of devices that transmit electronic signals and control information among vehicle components. SAE J1939 and its companion documents have quickly become the accepted industry standard and the vehicle network of choice for off-highway [...]
