SAE J1939 Data Acquisition System For Diesel Engines Measures And Records 23 Suspect Parameter Numbers (SPNs)
The Titan S8-CAN by Madgetech (USA) represents a data acquisition system for diesel engines that simultaneously measures and records 23 suspect parameter numbers (SPNs). The portable data logger suits 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 [...]
Design Of Proprietary Parameter Group Numbers (PGNs)
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. [...]
SAE J1939 Data Traffic Generator For Diesel Engine Network Simulation
I am writing this post to respond to multiple inquiries from newcomers to the SAE J1939 technology. Most questions are like, "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 a bit more [...]
Arduino-Due-Based SAE J1939 Programming Kit - Quick Start Reference
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 [...]
Testing NMEA 0183 For The PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi
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 [...]
SAE J1939 250k/500k Baudrate Converter Using Arduino Due With Dual CAN Bus Port
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 to keep things simple and reliable. I don't know what triggered the decision to add the 500k baud rate. From a technical [...]
SAE J1939 Protocol Converter Supports Modbus And Ethernet Connectivity
Axiomatic Technologies announced the release of their AX141810, a Modbus router with CAN Bus and Ethernet connectivity. It is available in two variants. The protocol converter is user-configurable via a web browser, featuring data exchange between a CAN Bus network, specifically SAE J1939, EIA-485, and Ethernet.The unit integrates one isolated extended frame format CAN Bus interface, [...]
ESP32 Project: CAN Bus, SAE J1939, NMEA2000 Converter With IoT Functionality
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 [...]
SAE J1939 vs. CAN Bus - What's the Difference?
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 [...]
CAN FD Data Logger For CAN Bus Monitoring, DBC Logging, Message Filtering, SAE J1939 Logging, And Trigger Events
Influx Big Data Solutions introduces their ReXgen 2 CAN Bus logger, one of the smallest, compact, robust, and powerful handheld CAN Bus data recorder available in the market today. The device is targeted at applications requiring CAN 2.0 and CAN FD data recording capabilities. The data logger comes with a freely distributable ReXgen data logger configuration [...]
