The SY210NT series controller is part of the SY series products, which mainly include SY210NT series induction controller, SYRD series induction card reader, MDDIDO-1S module, MDPRINT-1S module, and induction card, etc. This document describes the connection methods and usage of the products.
This manual introduces the SY210NT series induction controller, its system architecture, and compatible modules such as card readers, DIDO modules, and printer modules. It includes detailed diagrams for device connections, wiring tables, and the main functional flow of the system.
The guide walks users through initial power‑up, fault detection, password login (default 1234), ID configuration for controllers and card readers, module plug‑and‑play procedures, and basic operation settings like DO/DI scheduling, print modes, and alarm configuration. This manual is written in Chinese.
