RS232 to RS485 Converter, Bi-Directional Serial Adapter, Auto Transceiver, DB9 Connector

This RS232 to RS485 converter is a bi-directional serial communication adapter designed to convert standard RS232 signals to RS485 differential signals, allowing long-distance and noise-resistant data transmission. Ideal for industrial automation, POS systems, and embedded applications, it features automatic send/receive switching without requiring software driver configuration. The converter is powered directly from the RS232 interface and typically comes with a DB9 male connector on the RS232 side and screw terminals or a 2-pin/3-pin connector on the RS485 side. Its compact, lightweight design enables easy integration into existing systems for reliable and efficient serial communication.

Key Features:

• Converts RS232 signals to RS485 differential signals
• Supports long-distance communication up to 1200 m at 9600 bps
• Automatic data direction control (no external power required)
• DB9 male connector for RS232 interface
• Screw terminals or 3-pin header for RS485 side connection
• Excellent anti-interference performance with opto-isolation (model dependent)
