A DC-Bus is a network technology provided by Yamar Electronics (Yamar) which passes data over the DC power lines of a system. Warwick Control have developed a LIN DC-Bus which passes LIN messages between ECUs using a vehicle’s 12 volt power lines. A LIN DC-Bus protocol stack in the C programming language interfaces the automotive application software with Yamar’s SIG60 transceiver. A DC-Bus to USB interface passes messages to and from Warwick Control’s popular X-Analyser network analysis tool.
The LIN DC-Bus is a good option for retro fitting of ECUs or providing a backup data channel without the need to install additional wiring. It is also a good technology for wiring harness weight reduction.
