ELD Concept: SAE J1939 Data Recording And Display Using Android Or iOS Devices
An electronic logging device (ELD) is electronic hardware that is attached to a commercial motor vehicle engine to record driving hours. The driving hours of commercial drivers (truck and bus drivers) are regulated by a set of rules known as the hours of service (HOS). The Commercial Vehicle Driver Hours of Service Regulations vary in Canada and [...]
SAE J1939 Address Management Messages (Address Claim PGNs)
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. According to SAE J1939/81, network management procedures are used to “collectively manage the network”.While other higher layer protocols based on CAN Bus do not support dynamic node address assignments per default, the SAE J1939 standard provides yet another ingeniously designed feature to uniquely identify ECUs [...]
SAE J1939 Joystick With Multi-Axis Hand Grip Controller For Off-Road Vehicles And Machinery
The XD series of joysticks by Apem is a multi-axis hand grip controller engineered for demanding vehicle applications in harsh environments, and it supports the SAE J1939 higher-layer CAN Bus protocol.The joystick feature non-contacting Hall effect technologies fit for off‑highway vehicles and machinery. It measures 60 mm below the panel, yet resists horizontal loads of up to 400 [...]
SAE J1939 Starter Kit And Network Simulator - Quick Start
Our jCOM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner experimenting with SAE J1939 data communication without the need of connecting to a real-world J1939 network, i.e., a diesel engine. To establish a network, you need at least two nodes, and that fact applies especially to the CAN Bus [...]
Programmable SAE J1939 Analog Signal Output Controller
The 4 Analog Signal Output CAN Bus Controller by Axiomatic extends machine control networks by adding I/O control to the CAN Bus. Diesel engine control systems with SAE J1939 can communicate with 4-20 mA or other analog signal input devices using this controller as a smart interface. The controller can be configured to accommodate a particular application utilizing [...]
SAE J1939 Simulator Generates Frequently Used SAE J1939 Signals (PGNs) For Diesel Engines
Our SAE J1939 ECU Simulator Board With USB Port allows any host device (e.g., PC) with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network, which makes it also suitable to simulate SAE J1939 data traffic. The simulation of SAE J1939 signals (i.e., PGNs) is a valuable [...]
SAE J1939 And CAN Bus Display Gauges For Off-Road And On-Road Vehicles
Veethree Technologie (UK) offers a range of CAN Bus and SAE J1939 LCD display gauges. The range of gauges directly wires to an SAE J1939 compliant CAN Bus without needing another device to drive them. Compact and easy to install, the gauges are available in 2″ & 3" sizes, in conventional black or white dial colors with chrome [...]
SAE J1939 vs. CAN Bus - Physical Layer And Higher Layer Protocol (HLP)
To answer the fundamental question upfront: SAE J1939 is a higher-layer protocol (i.e., an add-on software) that uses the CAN Bus technology as a physical layer. In addition to the standard CAN Bus capabilities, SAE J1939 supports node addresses, and it can deliver data frames longer than 8 bytes (in fact, up to 1785 bytes). However, [...]
Repeaters for CAN Bus, CAN FD And CAN-Based Higher Layer Protocols Such As CANopen And SAE J1939
Adding to the current IXXAT line of CAN bridges and gateways, HMS Networks launched four Ixxat CAN FD repeaters, all supporting both the new CAN FD standard as well as traditional CAN Bus.With the IXXAT CAN FD repeaters, HMS allows the networking of existing CAN Bus systems as well as in CAN FD-based systems.The repeaters enable CAN FD (CAN [...]
Low-Cost Do-It-Yourself CAN Bus To WiFi, Bluetooth, BLE, USB, RS485 Gateway Based On Raspberry Pi Zero
In the following, I will discuss a do-it-yourself project utilizing the Raspberry Pi Zero in combination with the CAN Bus Plus RS485 HAT. The combination of serial and wireless ports provided by this system allows the development of a great number of gateway applications. Overall, this small-size hardware includes connections such as CAN Bus, RS485, [...]
