ATC-2000 is a communication interface converter that is used to complete data conversion between TCP/IP and RS-232/422/485, and it is widely used in industrial control, access control, attendance system, meal system, POS system, building automation system, power system, monitoring and data acquisition system, self-service banking system, etc.
The ATC-2000 is a TCP/IP to RS‑232/422/485 communication converter designed for industrial control, access control, POS and monitoring systems. The manual provides an overview of the device, its main functions, and the default network configuration.
Key sections cover hardware installation, initial power‑on settings, detailed system configuration (serial mode, IP, DDNS, PPPoE), virtual COM port software setup, system management features, and a troubleshooting guide with common LED indicators and error messages. This manual is written in Chinese.
