System-S RS232 to RS485 Converter Adapter Serial Data Adapter

The System-S RS232 to RS485 Converter Adapter is a device designed to enable conversion between the RS-232C and RS-485 standards. Here are its key features and specifications:

• Compatibility: The converter is compatible with the RS-232C and RS-485 standards according to EIA/TIA. It supports asynchronous, half-duplex operation.

• Transmission Media: It can be used with a variety of transmission media, including PUS, twin wire, UTP or protective line.

• Transmission speed: The transmission speed ranges from 300 to 115200 bps.

• Transmission range: The range is up to 5 meters at the RS-232 end and up to 1200 meters at the RS-485 port.

• Voltage and environment: The converter requires an operating voltage of 9 to 12 V and operates in a temperature range of -10 to 85 degrees Celsius at a relative humidity of 0% to 95%.

• Signals: The RS-232 signals include TXD, RXD, RTS, CTS, DTR, DSR, DCD, and GND. The RS-485 signals include Date+, Date-, GND, and +12V.

• Pin assignment: The pin assignment is via a DB9 socket for RS-232C and a separate terminal for RS-485.

• Scope of delivery: The scope of delivery includes the RS232 to RS485 converter adapter.

This converter enables reliable and flexible communication between devices using the RS-232 and RS-485 standards, making it ideal for various industrial applications.
