Reviews
This passive RS232 to RS485 communication converter realizes seamless signal conversion between RS232 and RS485 serial interfaces without external power supply, drawing power directly from the RS232 COM port signal. It adopts bidirectional transparent transmission technology to forward data completely without protocol delay, ensuring real-time stable communication.
Integrated TVS surge protection and ESD anti-interference circuits effectively filter industrial workshop electromagnetic noise and instantaneous voltage surges, avoiding equipment communication failures or burnout. Mini lightweight housing saves installation space inside control cabinets and test benches, with plug-and-play operation that requires no extra configuration or driver installation.
RS485 differential transmission supports stable long-distance data transmission, suitable for connecting desktop serial hosts to PLC controllers, temperature transmitters, frequency inverters, access control systems and various industrial monitoring sensors. It is an essential low-cost serial conversion accessory for on-site equipment debugging and automation project wiring transformation.
