Passive RS232 to RS485 Serial Port Converter Adapter with LED Status Indicator

The Converter is compatible with RS-232 and RS-485 standards. It can convert RS-232 signals to differential RS-485 signals. The built-in high-sensitivity receiving circuit enhances weak signal amplification, while transient voltage suppression (TVS) provides fast protection.

The device requires no external power supply, as it utilizes a specialized internal "RS-232 Charge Pump" to drive the entire circuit, enabling zero-delay operation.

It features an automatic transmission conversion mechanism and an automatic data flow direction control system, which prevents I/O circuit collisions. This ensures that programs written for RS-232 mode can run seamlessly in RS-485 mode without modification, fully maintaining compatibility with existing software and hardware interfaces.
