Configurable Display for Off-Road Vehicle Engines with SAE J1939 interface

Posted by Industry News on

EngineMonitorPlus - Configurable Monitor for industrial engines with J1939 interface

The EngineMonitorPlus is a display and control device with a CAN Bus interface designed specifically for use in off-road vehicle engines. It supports the most common messages (PGN, Parameter Group Number) of the SAE J1939 standard. Furthermore, it provides a simple configuration of displayed parameters, errors (DM1), and service messages, allowing the user to configure and customize it for specified applications. 

The configuration feature utilizes three pages with two layout options on each page. One quadrant layout value can be switched via buttons or time-based. Values in the row view and four-quadrant layout can be shown at one time. In a password-protected menu, the engine control, additionally SCR / DPF regeneration, and SCR / DPF warning lamp can be activated. The software is available for two display variants. With an IP67 grade, both are ideally suited to operate under rough environmental conditions.

Supported parameters include:

  • Engine Percent Load At Current Speed
  • Engine Oil Level
  • Engine Air Inlet Pressure
  • Accelerator Pedal
  • Engine Oil Pressure
  • DPF Active Regen Status
  • Actual Engine - Percent Torque
  • Engine Coolant Pressure
  • Engine Speed
  • Engine Coolant Level
  • Auxiliary Temperature
  • Exhaust High Temp Lamp
  • Engine Fuel Rate
  • Auxiliary Pressure #1
  • Engine Total Hours of Operation
  • Engine Instantaneous Fuel Economy
  • Total Engine Revolutions
  • Engine Average Fuel Economy
  • Wheel-Based Vehicle Speed
  • Engine Trip Fuel
  • Engine Throttle Position
  • Engine Total Fuel Used
  • Barometric Pressure
  • Engine Coolant Temperature
  • And many more…

SAE J1939 Starter Kit And Network Simulator

SAE J1939 Starter Kit And Network Simulator

Our J COM.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 J1939 network, i.e. a diesel engine. It may sound obvious, but in order to establish a network, you need at least two nodes, and that fact applies especially to CAN/J1939 where the CAN controller will basically shut down after transmitting data without receiving a response. For that reason, our jCOM.J1939 Starter Kit And Network Simulator consists of two J1939 nodes, namely our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port.

Dual-Channel Linear Actuator Control Module with ESP32 Processor

As part of a customer project, I, with the help of a capable hardware designer, developed an embedded system to control two linear actuators, specifically the Thomson Electrac HD model with SAE J1939 interface.  The Electrac series of actuators supports two higher-layer protocols (HLP) based on Controller Area Network (CAN): CANopen, and SAE J1939. CANopen is [...]

Diesel Engine Fluid (DEF) Sensor Simulator - Background Information and Assembly Instructions

DEF systems in modern diesel engines are crucial to reducing Nitrous Oxide (NOx) emissions and protecting the environment. The DEF system combines software, hardware, and DEF fluid that enable this critical task. Unfortunately, a flood of failures has recently affected one of the elements of the DEF system called the DEF sensor. The origins of [...]

SAE J1939 250k/500k Baudrate Converter with Arduino Due - Source Code Included

The introduction of 500 Kbps (see SAE J1939/14) as an alternative to 250 Kbps, required clarifications on how to solve problems that come with incorporating devices supporting different baud rate settings in the same network. One solution comes with automatic baud rate detection. The SAE J1939/16 document outlines the methods used to detect the baud rate [...]

Under Development: Programmable CAN Bus to USB, Bluetooth, BLE, WiFi Gateway

For the longest time, I had resisted the idea of creating my version of a CAN-to-USB gateway, primarily due to the vast competition. A professional CAN/J1939 development requires a professional CAN-to-PC solution to monitor data traffic. I am pleased with the PEAK PCAN-USB device, as shown in the above image. However, not everybody is willing [...]

Selection Criteria and Requirements for a Telematics Gateway

The  March 2023 issue of the CAN Newsletter, a CiA (CAN-in-Automation) online publication, posted an article on the selection criteria and requirements for a Telematics gateway. With cars evolving towards network technologies, OEMs (Original Equipment Manufacturers) require telematics solutions that boost seamless communication within and outside the vehicle. The device should be cloud-enabled, connectable to servers for real-time [...]
