What is ISO 17987‑8 - DC powerline electrical physical layer for the LIN about?
ISO 17987‑8 is a series of international standards on road vehicles that specifies the requirements for implementations of the DC powerline electrical physical layer (EPL) for the LIN communications system as well as a conformance test plan for the EPL.
ISO 17987‑8 is the eighth part of the ISO 17987 series of documents that specifies the transmission over the 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.
ISO 17987‑8 specifies the electrical characteristics, the modulation method of the transmission, and how to impose the carrier signal on the DC powerlines.
NOTE 1: The DC-LIN EPL supports bit rates of 9 615 bit/s, 10 417 bit/s, and 19 230 bit/s.
NOTE 2: The DC-LIN EPL is applicable for a wide range of DC powerlines including 12-V and 24-V operations, allowing communication between different DC powerlines via a coupling capacitor. NOTE 3: A DC-LIN EPL interface to powerline example is described in ISO 17987‑8.
Who is ISO 17987‑8- DC powerline electrical physical layer for the LIN for?
ISO 17987‑8 on local interconnect network (LIN) is relevant to:
- Road vehicle designers and manufacturers
- Personnel of power transmission networks
- Mechanical and electrical engineers
- Automotive industry
Why should you use ISO 17987‑8 - DC powerline electrical physical layer for the LIN?
Local Interconnect Network (LIN) is a serial network protocol used for the communication between components in vehicles.
ISO 17987‑8 navigates you through the electrical physical layer requirements which links the data link layer and the DC powerlines.
ISO 17987‑8 provides the characteristics of transmitter and receiver used in DC powerline and bit rate timing requirements.
ISO 17987‑8 explains the electrical parameters of the DC-LIN EPL signal on the line-out and line-in and general configuration for coupling to the DC powerline.
Furthermore, ISO 17987‑8 could help you standardize physical connection and data link layers to allow compatibility among multiple devices used within the vehicle. In this manner, you can achieve LIN that is easy to implement, reduces harness and makes vehicle more reliable and stable.
