Our CAN Bus / SAE J1939 Electronic Logging Device includes a number of hardware features allowing a great number of applications. These features include a wireless port (Bluetooth, BLE, or WiFi), an SD card, a GPS sensor, a CAN Bus port, an RS232 port, plus an optional SAE J1708/J1587 interface. All this is complemented by an extended input power range of 7 to 36 VDC and an extended temperature range of -40C to +85C. In regards to the software, we support CAN Bus, including OBD-II, and the SAE J1939 higher-layer protocol.
The jCOM.ELD.BT device is an OEM product, i.e., we at Copperhill Technologies modify the device's firmware according to your application requirements. We build applications through access to a vast software library that allows us to produce fully functional prototypes within the shortest time. Our strengths, skills, and passions include embedded hardware and software development, rapid prototyping, and manufacturing support. We guide you through the entire project cycle from development to finished product and beyond.
- SAE J1939 to Bluetooth Gateway With 9-Pin Deutsch Connection Cable
- SAE J1939 - GPS Module With 9-Pin Deutsch Connection Cable
- SAE J1939 to RS232 & USB Gateway With 9-Pin Deutsch Connection Cable
The existing hardware features allow further applications, and their sheer number required that we set priorities, mostly driven by customer demand.
- Wireless Port: We have successfully created an SAE J1939 to Bluetooth gateway, and the Bluetooth interface can be easily replaced by a pin-compatible BLE or WiFi module. At this time, the only missing link is the proof of concept, i.e. testing and documenting the wireless connection (the firmware does not need any modification).
- SD Card: We are currently working on an SAE J1939 data simulation device, and the availability of an SD card allows the storing of application parameters, i.e. the J1939 simulation will be fully user-programmable. Also, the next logical application for an SD card is the creation of a CAN Bus / SAE J1939 data recording device.
- CAN Bus Port: While our focus is primarily on SAE J1939, we also have created applications based on standard CAN Bus, including OBD-II. We are in the process of converting these customer-specific application into compelling products.
