In this post, I will demonstrate the test setup of our SAE J1939 to RS232 & USB Gateway. The JCOM.J1939.SER gateway is a high-performance, low-latency, serial 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.
In order to simulate SAE J1939 data traffic, rather than connecting to a real-world diesel engine, we utilize our SAE J1939 ECU Simulator Board With USB Port.
In fact, both devices are based on the same hardware concept and firmware, however, with slight differences. The J1939-to-USB gateway is designed for simulation and monitoring of SAE J1939 data traffic under lab conditions. The RS232-to-J1939 gateway is designed for operation connected to a diesel engine's network in order to monitor SAE J1939 data traffic.
Moreover, both devices can be controlled per our free-of-charge JCOM1939 Monitor Software.
The above image demonstrate the operation of two instances of the Windows software, one connected to COM Port 3 (USB), the other connected to COM Port 27 (RS232).
Both devices can also operate when connected to other devices such as embedded systems or Linux machines. The serial protocol (identical whether it's the USB or RS232 gateway) is documented in detail, and there are programming samples for Linux, Raspberry Pi, and Windows.

Data Acquisition from HD Vehicles Using The SAE J1939 CAN Bus
Data Acquisition from HD Vehicles Using J1939 CAN Bus focusses on guiding the reader on how to acquire and interpret data from the in-vehicle network of diesel engine vehicles. The reader will learn how to transform messages to scaled engineering parameters and determine the available parameters on the vehicles and their accuracy and update rate.
Written by two specialists in this field, Richard (Rick) P. Walter and Eric P. Walter, principals at HEM Data, located in the United States, the book provides a clear road map for the data acquisition user. The authors supply a transparent and concise description of the CAN protocol plus a review of all 19 parts of the SAE International J1939 standard family.
