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. 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.

Wall mountable bi-directional RS232 to RS485 splitter hub provides a quick, simple, and cost-effective solution for various serial data communication and automation applications. RS485 hub features built-in data collision protection control for reliable serial Data Communication; The baud rate will be detected and adjusted automatically, 300-115200 bps. Serial adapter with TX, RX and power indicators enables you to easily know the status of sending/receiving data respectively; 9V-30V DC power input is supported (DC 9V power adapter is included). Compact RS 232 to 485 adapter is designed with 600W lightning surge protection over RS485 link and 15KV ESD over RS232 link, to protect your value devices against high voltage. Powered RS232 to RS485 converter converts RS-232 signals to 2 wire half-duplex RS-485 signal, to extend RS232 signal distance, also expands RS485 networks ( up to 3 way).
