SAE J1939 Data Acquisition System For Diesel Engines Measures And Records 23 Suspect Parameter Numbers (SPNs)
The portable data logger is suitable for engine, road, and diagnostic testing applications. It connects to an SAE J1939 network via the diagnostic port and supports the monitoring and recording of SAE J1939 messages between Tier 1 and Tier 4 diesel engines. Furthermore, it captures up to 23 of the 55 available SAE J1939 SPNs simultaneously. In addition, the data logger measures and records temperature, current, voltage, and pulse information. Thus, the tool is helpful for diesel technicians and fleet owners, allowing preventative and predictive maintenance of their vehicle fleets.
The all-in-one solution allows users to view and record data simultaneously without needing a PC or software for operation. The touch-screen user interface allows a comfortable device setup and configuration. The data logger stores up to 5 000 000 readings by utilizing an internal 1 GB memory. A data view from the current logging session is possible as a graph, tabular, or in real-time. The stored data can be viewed, copied, and deleted, and the user can add notes to logged sessions. The collected data can also be downloaded to a flash drive via USB, allowing continuous operation of up to nine hours with the help of an internal battery. The IP20-rated device measures 168.9 mm x 111.8 mm x 35.8 mm (6.7" x 4.4 " x 1.4"). A 16-pin OBDII connector and a nine-pin Deutsch connector are also available.
SAE J1939 Starter Kit And Network Simulator
Our JCOM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner to experiment with SAE J1939 data communication without the need of connecting to a real-world SAE J1939 network, i.e. a diesel engine.
For that reason, our JCOM.J1939 Starter Kit And Network Simulator consists of two SAE J1939 nodes, namely our JCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP).
For a brief introduction to PGNs, see our post SAE J1939 Message Format and Interpretations of PGNs.As the name Proprietary Parameter Group Numbers implies, the SAE J1939 standard supports Parameter Groups in PDU1 and PDU2 Format that manufacturers can assign for their specific needs, which includes the design of the data field in the message.

I am writing this post in response to multiple inquiries from newcomers to the SAE J1939 technology. Most questions are in the nature of "Can your device simulate any PGN, for instance, engine speed in rpm?" or "Can your device simulate a 2014 Tonka Flex diesel engine?" The short answer is yes, but things are [...]
In the past, I frequently received inquiries regarding the availability of a four-channel CAN Bus gateway. Such devices exist in the marketplace; however, they are usually costly, and, after all, they don't support easy customization or programming. While we at Copperhill Technologies have the ability to create such a gateway, this is primarily a matter [...]
Unleash the power of the Arduino Due with ARM Cortex-M3 processor to develop and test your SAE J1939 application, may it be an SAE J1939 to USB protocol converter, an SAE J1939 Bridge, an SAE J1939 data monitor, and many more. The SAE J1939 Programming Kit comes with many programming samples, including a full-blown SAE J1939 [...]
PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi Our PICAN-M (M = Marine) is a Raspberry Pi HAT with NMEA 0183 and NMEA 2000 connection. The NMEA 0183 (RS422) port is accessible via a 5-way screw terminal. The NMEA 2000 port is accessible via a Micro-C connector. The board comes with a 3A SMPS (Switch [...]
The TQMax4xxl modules by TQ Systems represent an LGA (Land Grid Array) based on the Sitara AM243x microcontroller and the AM64xx processor with up to six cores from Texas Instruments. Possible applications include servo motor controllers (for robotics), industrial gateways, data collectors, and small edge servers in production, providing data for the cloud. The module size of [...]
In the past months, customers have approached me regarding a CAN Bus baud rate converter for SAE J1939 networks. The original SAE J1939 Standards Collection was limited to a baud rate of 250k, basically to keep things simple and reliable. I don't know what triggered the decision to add the additional 500k baud rate. From [...]
It was just a few weeks ago that I received some bad news. Due to the worldwide shortage of electronic components, the NXP LPC1754 processor we use for our SAE J1939 ECU Simulator with USB Port will not be available for several months, maybe even well into 2022. Consequently, it was time to rethink the design, and [...]
The TMU Pi3 telematics unit by Autopi (Denmark) utilizes the Raspberry Pi 3 Model A+ SBC, and it connects to in-vehicle CAN Bus networks via the OBD2 port.The device uses the 1,4-GHz Broadcom BCM2837B0 SOC with Cortex-A53 64-bit quad-core processor, including 512-MiB SDRAM and a 32-GiB micro SD card with installed Raspbian Jessie operating system and Autopi [...]
