Youwo Technology YW-630/YW-631 Modbus Reader Demo Program Manual
The document provides step‑by‑step instructions for operating the demonstration program that simulates a PLC interacting with RFID readers via the YW‑630/YW‑631 Modbus readers. It describes the three main interface areas – port operation, reader demo and settings, and status/result display – and shows how to open the serial port, select the reader ID, and perform basic read/write actions.
Further sections detail the configuration registers, including baud‑rate and station ID settings, card‑parameter registers, key registers, block data handling, and advanced options such as skipping key blocks, sleep mode, and data endian mode. The manual also lists the default register values and explains how to write to LED/buzzer controls and manage block data. This manual is written in Chinese.
