本文件规定了ISO 17987系列本地互联网络（LIN）的附加电气物理层（EPL）。它规定了在不影响LIN更高层（以下简称DC-LIN）的情况下通过直流电力线进行传输。 DC-LIN EPL使用高频调制载波通过直流电力线传播UART字节（面向字节）。 本文件规定了电气特性、传输的调制方法，以及如何将载波信号施加到直流电力线上。 DC-LIN EPL支持9 615位/秒、10 417位/秒和19 230位/秒的比特率。 DC-LIN EPL适用于广泛的直流电源线，包括12条- V和24 V操作，允许通过耦合电容器在不同的直流电源线之间进行通信。附录A中描述了DC-LIN EPL与电力线的接口示例。

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.
