TTL serial port to LIN bus/Lin module/auto bus/lin communication debugging/Lin to TTL serial port

1. Overview

1.1 TTL serial port to the lin bus module is a small intelligent protocol conversion product.The product can realize the two -way conversion between serial port and Lin data.At the same time, the intelligent protocol converter has the characteristics of small volume and convenient installation. It has a high cost performance in the development and data analysis application of Lin-BUS products. It is a reliable assistant for engineering applications, R & D, commissioning, and product development.

1.2 Features and functions

The two -way conversion between the TTL serial port and the Lin data; have a power indicator, the state indicator of the collection and hair;

Support the host request control frame, the host request the status frame;

Compatible with 3.3V/5V serial level;

The serial port does not need to be power supply independently, and the external Lin bus 12V or 24V can be connected; the data transmission rate of Lin can reach 20Kbps;

High electromagnetic compatibility (EMC) ability;

Built -in explicit timeout function;

LIN bus current limit protection function;

Compliance with Lin 2.0, Lin 2.1, Lin 2.2, Lin 2.2A, IS0 17987-4: 2016 (12V) and SAE J2602 standards

1.3 Application scenario

method:

1. First, use the USB to reconcile converter to connect this module (Elin-U01) and the computer, the RX of the converter's RX connected to the TX of the module, the TX connected to the RX of the module of the converter ;?

2. Use USB to lin debugger to connect this module (Elin-U01) and computers; (Elin-UO1) lin-to-end junctioner lin port, VCC connects the positive pole of the power supply, and the GND power supply is negative.The VCC and GND of the debugger also need to connect the positive and negative poles of the power supply; note: For the first time, use the USB to TTL serial port converter. You need to install software and drivers. For detailed usage methods, please consult the relevant manufacturers.
