Asynchronous Half Duplex Communication This RS485 to RS232 converter allows to interface your devices using an RS232 communication link to an RS485 link and vice-versa. Say No to Signal Interference The rs232 to rs485 serial adapter is designed with built-in photoelectric isolation ( isolated voltage 2.5KVrms/500VDC), which enable you to get reliable data and to effectively prevent the destruction of both ends of the electric equipment. Double Protection A built-in transient voltage suppressor (TVS) enables you to get double 600W lightning surge protection against the lightning strike over RS485 link, and 15KV static protection over RS232 link effectively protect your value devices against high voltage spikes. Simple Operation DCPC (Data Collision Protection Control) function can detect the incoming or outgoing data and automatically switch into the send or receive mode, then you don't have to worry about the data collision problems. It only requires three lines (RX, TX and GND) to get a RS232 to RS485 conversion, making it great for troubleshooting the serial system, fully plug and play. Specific RS232 Link - 9 pin female port. RS485 Link - 9 pin male port, 4 position terminal board. EIA/TIA RS-232C, RS-485 specification. Up to 32 nodes Transmission Distance - 4000ft over RS485 link, 50ft over RS232 link. Transmission Media - twisted pair (>=24 AWG ) or shielded cable. Applications Computer Factory industrial automation control system Micro controller (MCU) Door safe / Parking system SCADA (supervisory control and data acquisition) ...

The baud rate will be detected and adjusted automatically, up to 115200 bps; RS485 isolator is port powered from RS-232 signal, no external power required. RS 232 to 485 opto isolator serial adapter supports 2 wire half duplex communication, point to point and point to multi-point network (up to 32 drops RS-485 protocol devices). Industrial Grade conversion adapter with TX and RX indicators enables you to easily know the status of sending or receiving data respectively. Port powered RS485 to RS232 optical isolator supports 600W double lightning surge protection and 15KV static protection protects your value devices against high voltage spikes created by either by static electricity or by surges in the supply voltage. Mini size isolated RS232 to RS485 converter with 2.5KVrms /500VDC photoelectric isolation voltage helps you get the precise data and protect your valued electric terminal devices from damage.
