Bi Directional Communication Data Rs232 To Rs485 Serial Converter Stm485s

The Bi-directional RS232-485 Serial Converter is an essential device for communication between electronic controllers, particularly in systems like industrial automation, access control, parking systems, and other telemetry applications. It allows seamless data transfer between RS-232 and RS-485 devices without the need for an external power source, making it highly efficient and cost-effective.

Key Features:

• RS-232 to RS-485 Conversion:

  • Converts the TXD and RDX signals from RS-232 serial port to half-duplex RS-485 signals.

• No External Power Required:

  • The converter uses the power from the RS-232 port via Pin 3 and Pin 7 (RTS) for operation, eliminating the need for an external power source.

• Universal Compatibility:

  • RS-232: Compatible with EIA/TIA RS-232C standard.

  • RS-485: Compatible with RS-485 standard, providing reliable long-distance communication.

• Working Mode:

  • Supports Asynchronous, half-duplex, and differential transmission for robust communication.

• Versatile Application:

  • Ideal for industrial automation systems, universal card systems, parking systems, banking systems, bus ticketing systems, access control systems, restaurant menu systems, personal care systems, and road toll systems.

• Long Transmission Range:

  • RS-485 can transmit up to 1200 meters, while RS-232 can transmit up to 5 meters.

Specifications:

• Interface:

  • RS-232: DB9 female (hole-type) connector.

  • RS-485: DB9 male (needle-type) connector with a connection board.

• Transmission Rate:

  • 300 to 115200 bps (adjustable for different requirements).

• Telecommunications Protocol:

  • Transparent, allowing for seamless data transfer between systems.

• Mechanical Dimensions:
