USB-CAN PC Interface with SAE J1939-13 Type II Connector
Posted by on
The Leaf Light HS v2 J1939-13 Type II, a standout in Kvaser's Leaf Light product series, is renowned for its reliability and affordability in connecting any CAN network to a PC or mobile computer. It's not just a workhorse but a dependable and cost-effective solution.
The Leaf Light HS v2 J1939-13 Type II is a device that allows easy connection between a PC and the onboard computer of any J1939-compliant vehicle or industrial system. You can obtain diagnostic data using its USB 2.0 connector and a 9-pin J1939-13 (Type II) compliant CAN connector, color-coded in green and supports either 250 Kbps or 500 Kbps vehicle networks.
Major Features
- Standard “A” USB connector and a J1939-13 Type II compliant CAN connector.
- Capable of sending up to 8000 messages per second, each time-stamped with 100 microsecond accuracy.
- Supports 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B active) identifiers.
- High-speed CAN connection (compliant with ISO 11898-2), up to 1 Mbit/s.
- Galvanic isolation, enhancing protection from power surges or electrical shocks.
- Support for SocketCAN. See elinux.org for details.

- RP1210A Application Programming Interface available.Online documentation is in Windows HTML-Help and Adobe Acrobat format.
SAE J1939 Starter Kit and Network Simulator
Our J COM.J1939 Starter Kit and Network Simulator is designed to allow the experienced engineer and the beginner to experiment with SAE J1939 data communication without the need to connect to a real-world J1939 network, i.e., a diesel engine.
To establish a network, you need at least two nodes, which applies especially to CAN/J1939, where the CAN controller will shut down after transmitting data without receiving a response. Therefore, 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.
A New Generation of SAE J1939 Gateway, ECU Simulator, and Starter Kit
Like many other businesses, we have to deal with the global shortage of electronic components. For instance, the NXP LPC 17xx processors we used for our SAE J1939 gateways and the starter kit are not available at this time. Even worse, there is no reliable information if/when production resumes. This situation forced us to rethink [...]
Testing The SAE J1939 to RS232 & USB Gateway By Copperhill Technologies
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 [...]
Updated Version Of JCOM1939 Windows Software For Monitoring And Recording SAE J1939 Data Traffic
The JCOM1939 Monitor Software for Windows complements our JCOM.J1939.USB gateway board, a high-performance, low-latency vehicle network adapter for SAE J1939 applications. The gateway allows any host device with a USB COM port to monitor and record SAE J1939 data traffic and communicate with an SAE J1939 vehicle network. The board supports the full SAE J1939 protocol according to J1939/81 [...]
Contactless CAN Bus And SAE J1939 Data Monitoring With CANCrocodile
For the longest time, i.e. since the time we introduced our contactless CAN Bus readers, I had been eager to play with the CANCrocodile and read/monitor CAN Bus data traffic in a truly unique way. The setup, as shown in the above image, took less than 30 minutes to assemble (some soldering was required) and to finally [...]
Non-Contact Sensing Of Classical CAN/CAN FD Signals
Hioki (Japan) has launched its clip-on device for non-contact monitoring of Classical CAN/CAN FD signals up to 3 Mbit/s, which allows the analysis of network signals without a direct galvanic connection.The SP7001 and SP7002 modules implement a 9-pin Dsub plug for connection to CAN interface modules such as, for instance, USB dongles. The link to the [...]
SAE J1939 Monitor, Analyzer, And ECU Simulator For Windows - New Byte & Bit Editing Mode
The jCOM1939 Monitor Software by Copperhill Technologies is the ideal software tool for monitoring, analyzing, and simulating SAE J1939 data traffic. The program links to our jCOM.J1939.USB ECU Simulator Board that operates as an SAE J1939 to USB (or UART) gateway. This comprehensive and easy-to-use, easy-to-understand Windows software illustrates not only SAE J1939 data traffic; it also allows the [...]
