Detailed Product Description:

The RS232 to RS485 Interface Converter is an essential tool for creating a reliable point-to-point or multi-point communication network. This robust adapter converts RS-232 serial port signals (TXD and RXD) into balanced, half-duplex RS-485 signals, making it ideal for a wide range of applications.

Unlike other converters, this adapter is powered directly by the RS232 port, drawing power from the RTS and DTR pins, which means you don't need an external power supply. It also features automatic flow control, simplifying setup and use without the need for additional software or hardware configuration.
