The design addresses the harsh environments of engine applications. The CAN Bus gateway operates on 12 VDC or 24 VDC nominal power. A block library is available for modeling the converter using Mathworks' Simulink development system.
- Acts as a gateway or interface between CAN buses with different baud rates and protocols (SAE J1939- SAE J1939 or SAE J1939-CANopen)
- Fast data exchange between a CAN network (SAE J1939 or CANopen) and a RS-485 bus (SAE J1587 or Modbus RTU)
- 2 Isolated CAN ports (CAN 2.0B)
- 1 Isolated RS-485 serial port
- Operational from 9 to 36 VDC (12 VDC, 24 VDC nominal)
- Integrated Deutsch IPD 12-pin connector
- Fully sealed enclosure with a rugged IP67 protection rating
- Compact size
- CE mark
- User configurable using Axiomatic Electronic Assistant
- Mathworks Simulink block library is available
SAE J1939 to RS232 & USB Gateway With 9-Pin Deutsch Connection Cable
The jCOM.J1939.SER gateway is a high-performance, low-latency, wireless vehicle network adapter for SAE J1939 applications. It allows any host device with an RS232 or USB port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network. An SAE J1939 cable, suited for a 9-pin Deutsch connection, is included with the gateway.
The gateway supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.
We at Copperhill Technologies have designed an SAE J1708-to-UART breakout board, and we are in the process of adding it to our e-commerce website. However, what we learned during the development is that the device is in need of some massive software support as I will explain in the following.First of all, to go into [...]
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee has developed a family of standards concerning the design and use of devices that transmit electronic signals and control information among vehicle components. SAE J1939 and its companion documents have quickly become the [...]
The CR-HD unit is the perfect tool for diagnosing and clearing heavy duty diagnostic trouble codes. It covers SAE J1587, SAE J1708 and SAE J1939 protocols for accessing Engine, Transmission, Brakes and more. It features a 2.8” full color LCD display and is ergonomic, highly portable and easy to use. Perfect Scan Tool for Heavy Duty Truck works on [...]
As part of our business strategy of providing prototyping solutions for the CAN Bus (including SAE J1939, ISOBUS, NMEA 2000) we have decided to focus more on the Arduino platform, specifically the Arduino Due. The Due, while providing the power of an ARM Cortex M3 processor, comes with two CAN Bus ports per default, however, lacking [...]
SAE J1708 is a standard used for serial communications between ECUs on a heavy duty vehicle and also between a computer and the vehicle. With respect to Open System Interconnection model (OSI), J1708 defines the physical layer. Common higher layer protocols that operate on top of J1708 are SAE J1587 and SAE J1922. The protocol [...]
First of all, let me point out that this post is merely about monitoring SAE J1708/J1587 data traffic, i.e. the mere reading of data frames. SAE J1708, the hardware layer, is based on RS485, however, with a small hardware modification that allows message collision detection and prevention. In the following, I am using an RS485 [...]
