RS232 To RS485 Converter Adapter

Product description

High quality RS232 to RS485 Transmitter Converter Communication Data Adapter. 
Bi-direction connectors conver of this converter is mainly used between main controllers. 
RS232 to RS485 Converter can transfer the TXD and RXD signals of RS-232 interface and at the same time, after 7 pin's requirement of sending RTS, 4 pins data terminal prepares DTR to help supplying this converter. 
RS232 Converter automatically process control make you need to reset and make an easy application of the hardware and software installation.
