This operation manual mainly introduces the function overview, system features, transmission format, controller appearance, controller communication settings and controller wiring diagrams of network centralized controller, aiming to help users better understand and use network centralized controller.
This manual introduces the SC network centralized controller, describing its role in connecting multiple access‑control field units and alarm controllers to a management computer. It outlines system features such as TCP/IP support, RS232/RS485 interfaces, and status indicator LEDs.
The document provides detailed transmission specifications, front‑ and rear‑panel descriptions, communication settings (baud‑rate DIP switches, pin definitions), and wiring diagrams for connections to computers, LAN hubs, field controllers, and alarm controllers. This manual is written in Chinese.
| Communication mode | Half‑duplex |
|---|---|
| Communication interfaces | RS232, RS485, RJ45 (TCP/IP) |
| Transmission speed options | 4800 BPS, 9600 BPS, 19200 BPS |
| Transmission code | ASCII |
| Physical size | Standard 1U rack design |
Use the four‑digit DIP switch on the controller; 4800 BPS is ON OFF OFF, 9600 BPS is ON OFF ON, and 19200 BPS is ON ON OFF.
The controller provides an RS232 port for PC communication, an RS485 port for field controllers, and an RJ45 port for TCP/IP networking.
Connect the controller’s DB‑9 pins 2, 3, and 5 to the computer’s corresponding DB‑9 pins 2, 3, and 5 for RS232 communication.
Yes, the controller supports TCP/IP via a standard RJ45 port and can be connected to a LAN hub.
