SAE J1939 Diagnostic Device Includes a PGN, SPN Database
The handheld PCAN-Diag FD device from PEAK-System supports diagnosing communication on a CAN (FD) network. In addition, a separately available extends the functionality to analyze SAE J1939 data traffic. The SAE J1939 Standard describes communication in utility vehicles via CAN Bus. The standard specifies messages and data for transmitting diagnostic and control information using PGNs (Parameter Group Numbers) and SPNs [...]
SAE J1939 - Simulation of Request Message with J1939 to USB Gateway
The above image shows my SAE J1939 test setup with a total of three nodes, all connected through our CAN-Bus Hub with 7 Ports and DC Power Connection. They are: SAE J1939 to USB Gateway in Plastic Enclosure... SAE J1939 ECU Simulator Board With USB Port... PEAK PCAN-USB Pro FD - CAN, CAN FD, and LIN Interface for [...]
Quick Prototyping by Copperhill Technologies
As they say, a picture tells a thousand words. The above image demonstrates a predicament we encountered a few days ago. The enclosure we are using for our SAE J1939 Gateway And Data Logger With Real-Time Clock is not available at the moment, and it might take a few more months before new supplies arrive. At [...]
SAE J1939: Simulation of Analog and Digital Signals with the JCOM1939 Monitor Software
The JCOM1939 Monitor Software is ideal for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. The system 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 scans the network, simulates an ECU (incl. full node address negotiation features), and responds [...]
Any CAN Bus, SAE J1939, NMEA 2000 Development Requires the Right Testing Tools
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 [...]
Data Acquisition from Heavy Duty Vehicles Using SAE J1939 CAN Bus
Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or ‘controllers’) are networked to convey information and output measured and calculated data to each other.This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet [...]
NMEA 2000 / SAE J1939 Data Scanner with BLE Interface for iOS Applications
This post is a follow-up on NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications. In this new post, I also include SAE J1939, since NMEA 2000 is based on J1939. Also, in this particular case, instead of the NMEA2000-compatible 5-pin M12 connector, I used a DSUB9 as it applies to the CAN Bus [...]
NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications
Our N2K-BT gateway functions as a NMEA 2000 to Bluetooth data scanner for any host device with a Bluetooth or BLE (Bluetooth Low Energy) port, such as PCs, phones, or tablets. Therefore, it supports operating systems such as Windows, Linux, iOS, Android, and more. In addition, the wireless communication protocol employs easy-to-read and easy-to-process ASCII [...]
Agricultural Control Unit Supports Isobus, SAE J1939, and CANopen Connectivity
The EC44 Agri control unit by Epec (Finnland) supports Isobus communication for agriculture applications. In addition, the device can upgrade existing systems to Isobus connectivity when used as a gateway. The Isobus-compliant device allows plug-and-play compatibility between tractors and other agricultural equipment (e.g., seeders or fertilizers) from different manufacturers and brands. Legacy implementations operated via customized human-machine interfaces (HMI), i.e., [...]
SAE J1939 Enabled Temperature Scanner Monitor up to 20 Thermocouples and Two RTDs
Axiomatic, a designer and manufacturer of electronic controllers and power management converters, introduced their AX180800 temperature scanner that monitors up to 20 thermocouples and two RTDs. The device features two SAE J1939 interfaces. The channels are independently configurable as Type J, K, B, E, N, R, S or T thermocouples, measuring exhaust, winding, and fluid temperature. All temperature data are [...]
