This converter is compatible with RS-232 and RS-485 standards, and can convert single-ended RS-232 signals into balanced differential RS-485 signals. The communication distance can reach 1.2 kilometers. Built-in TVS, support 600W anti-surge and 15KV electrostatic protection, driven by RS-232 charge pump, it can be turned on without external power supply. The built-in zero-delay automatic transceiver conversion I/O circuit can automatically control the data flow without any handshake signal.

APPLICATION

• Industrial automation control systems
• All-in-one cards
• Access control systems
• Consumer systems
• Attendance systems
• Parking lot systems
• Self-service banking systems
• Traffic system

Note

In the case of insufficient power supply, the active RS485 converter DTE (Data Terminal Equipment) needs to be replaced
