Road vehicles. Local Interconnect Network (LIN). Electrical physical layer (EPL) specification: LIN over DC powerline (DC-LIN)
43.040.15 - Car informatics. On board computer systems
This document specifies an additional electrical physical layer
(EPL) for the Local Interconnect Network (LIN) of the ISO 17987 series. It specifies
the transmission over DC powerline without affecting the LIN higher
layers, hereafter named DC-LIN.
The DC-LIN EPL uses a high-frequency modulated carrier to
propagate UART bytes (byte-oriented) over the DC powerline.
This document specifies the electrical characteristics, the
modulation method of the transmission, and how to impose the
carrier signal on the DC powerlines.
The DC-LIN EPL supports bit rates of 9 615 bit/s, 10 417 bit/s,
and 19 230 bit/s.
The DC-LIN EPL is applicable for a wide range of DC powerlines
including 12-V and 24-V operations, allowing communicating between
different DC powerlines via a coupling capacitor. A DC-LIN EPL
interface to powerline example is described in Annex A.
