Product description
I. Overview
1.1 TTL serial to LIN bus module is a small intelligent protocol conversion product. It can realise bi-directional conversion between serial port and LIN data. At the same time, the intelligent protocol converter has the characteristics of compact size, easy to install, etc., and it has a very high cost performance in LIN-BUS product development and data analysis applications, and it is a reliable assistant for engineering applications, R & D debugging and product development.
1.2 Features and Functions
Bi-directional conversion between TTL serial port and LIN data; with power indicator, receive and transmit status indicator.
Support host request control frame and host request status frame.
Compatible with 3.3V/5V serial port level.
Serial port does not need independent power supply, connected to the external LIN bus 12V or 24V can be; LIN data transfer rate up to 20kbps; High EMC (Electromagnetic Compatibility); LIN data transfer rate up to 20kbps; LIN data transfer rate up to 20kbps.
High EMC (Electromagnetic Compatibility) capability.
Built-in explicit timeout function.
LIN bus current limit protection.
Complies 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 Scenarios
Industrial control LIN-BUS networks Automotive LIN bus commissioning Security, fire networks
Underground remote communication
Public address system
car park equipment control.
Intelligent building

Method.
1. Firstly, use the USB to serial converter to connect this module (ELIN-U01) with computer, the RX of the converter connects to the TX of this module, the TX of the converter connects to the RX of this module;? The USB end of the converter is directly connected to the computer.
2. Use the USB to LIN debugger to connect this module (ELIN-U01) with the computer; the LIN terminal of (ELIN-UO1) connects to the LIN port of the debugger, VCC connects to the positive terminal of the power supply, and GND connects to the negative terminal of the power supply. VCC and GND of the debugger should also be connected to the positive and negative poles of the power supply; Note: The first time you use the USB to TTL serial converter, you need to install the software and driver, please consult the relevant manufacturers for details of how to use.
