Analog Signal Output Controller With CAN Bus And SAE J1939 Port
Axiomatic has announced its AX130770, an ECU System converting CAN Bus data to two analog or digital isolated signals and one relay output for rugged engine applications.The relay output converter connects to a CAN Bus vehicle network (SAE J1939, high-speed SAE J1939m, or CANopen). It accommodates two analog/digital isolated signal outputs, which can be configured as 0 [...]
SAE J1939 Monitor Software - Setting Up PGN Simulation Such As Engine Coolant Temperature
In this post, I will explain the setup of SAE J1939 PGN simulation with our JCOM1939 Monitor software, and I will use the Engine Coolant Temperature as a randomly chosen example. Let me emphasize the point that you can set up any PGN with our software. However, please be also aware that you will need [...]
CAN Bus And SAE J1939 Prototyping With The Arduino Due ARM Cortex M3 Processor
Whenever it comes to building rapid prototypes for new CAN Bus or SAE J1939 applications, my first choice is regularly the Arduino Due, a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.In general, the Arduino platform couples an easy-to-use programming environment (IDE) with a vast number of hardware extensions (shields). While I do appreciate programming [...]
SAE J1939 to Bluetooth Gateway - Android Code (Java) Sample Code
Just as a fair warning upfront, the code that I am referring to in this post is not a finished sample code, but it demonstrates how to receive and decode SAE J1939 message frames (PGNs) from our JCOM Bluetooth device. Please be aware that we provide this code as a courtesy to experienced Android programmers (which [...]
SAE J1939 Data Logger Produces Excel-Compatible Files For Further Processing
Our free-of-charge JCOM1939 Monitor Software for Windows is a complete tool to monitor, analyze, record, and simulate SAE J1939 data traffic. It works in combination with our SAE J1939-USB gateways. The monitor software represents a comprehensive and easy-to-use, easy-to-understand tool that displays not only SAE J1939 data traffic; it also allows scanning the network, simulating an [...]
SAE J1939 Gateway Module With Updated JCOM1939 Monitor Software
The following is an update on the development (firmware plus supporting Windows monitoring tool) of our newest product, the SAE J1939 Gateway Module With USB Port, RTC, MicroSD Memory Card as shown here to the left. The JCOM.J939.USB-X SAE J1939 Processor board is an extended version of our popular JCOM.J9139.USB-B SAE J1939 ECU Simulator Board With USB [...]
ISOBUS Safety-Certified ECU With Three CAN Bus Ports And Automotive Ethernet Interface
TTControl expanded its HY-TTC 500 product family by another safety-certified ECU, the HY-TTC 508 ECU, which satisfies safety requirements according to IEC 61508 SIL2, ISO 13849 PL d and EN ISO 25119 AgPL d.One of the three CAN Bus interfaces is ISOBUS standard compliant. ISOBUS (ISO 11783) is a CAN (Controller Area Network) Higher Layer Protocol based on [...]
SAE J1939 And NMEA 2000 Protocol Stack Kits For Rapid Development And Prototyping
Warwick Control Technologies (UK) announced the release of their SAE-J1939-based protocol stack kits that also support an NMEA 2000 protocol stack according to IEC 61162-3.The company's development kit provides the protocol stack in C source-code, an STM32 prototyping board, a reference design CAN Bus driver for STM32 microcontrollers, the X-Analyser tool, and the Leaf Light USB dongle by Kvaser, [...]
SAE J1939 Communication Profile For Collision Detection And Avoidance Systems
The ISO 21815-2 technical specification, under development by the international ISO standardization body, defines the SAE-J1939-based communication interface for collision detection and avoidance systems. The growing adoption of hazard detection systems and avoidance technology safely supports machine operators in the field of mining and construction. Furthermore, there are demands to set standards for machines and systems able [...]
SAE J1939 Parameter Group Number (PGN) Range
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. With the definition of PDU Format (PF) and PDU Specific (PS) – as shown below - J1939 supports a total of 8672 Parameter Group numbers.The Parameter Group Number range is divided into two sections: Specific PGNs for peer-to-peer communication (PDU1 Format) Range: 00hex - EFhex (not including PDU Specific) Number [...]
