As they say, a picture tells a thousand words. The above image demonstrates a predicament we encountered a few days ago. The enclosure we are using for our SAE J1939 Gateway And Data Logger With Real-Time Clock is not available at the moment, and it might take a few more months before new supplies arrive. At the same time, a customer of ours was in need of six units, and we needed a solution.
We have an excellent hardware designer, who took the printed circuit board (PCB) and constructed a new enclosure. Polycase offers a great variety of enclosures, and it was easy to find an enclosure that could accommodate the PCB with a few slight modifications (the DSUB9 connector is usually mounted directly to the board) plus the necessary cutouts.
In general, the global supply situation forced us to create new designs, and we are in the process of replacing a number of devices. However, while we grow with the challenge, the new designs result in more powerful solutions that open doors to more applications, specifically for the Internet-of-Things (IoT).
I want to reiterate a point made in a previous post ("A Beginner's Guide to SAE J1939 Embedded Software Development"): When developing and testing your CAN Bus application, may it be Classical CAN, CAN FD, CANopen, SAE J1939, or NMEA 2000, you need to connect your device to a functional network. One solitary node connected to your [...]
I am writing this post in response to multiple inquiries from newcomers to the SAE J1939 technology. Most questions are in the nature of "Can your device simulate any PGN, for instance, engine speed in rpm?" or "Can your device simulate a 2014 Tonka Flex diesel engine?" The short answer is yes, but things are [...]
