Signal

RS232—TXD, RXD, GND. RTS and CTS internal short-circuit.

RS485—485A, 485B, GND

Capable of converting TXD and RXD signals from RS232 serial ports into balanced half duplex RS485 signals without the need for an external power supply. It can directly steal electricity from the 3rd pin of the RS232 port, and send a request (RTS) through the 7th pin. The 4-pin data terminal is ready (DTR) to provide auxiliary power to RS232 to RS485. The RS232 flow control pin is internally short circuited to achieve automatic flow control.

  • Support baud rate up to 230400bps. Strong power supply under high baud rate can make long-time communication with no error code.
  • Unique exterior design, no exposed circuit board. RS232 TO RS485use integral shell, terminal-type RS485 wiring and flange installation, the appearance is beautiful, strong and safe.
  • The powerful compatibility with various RS232 interface.
  • With built-in RS485 TVS protection.
