    This passive DB9 RS232 to RS485 adapter converts RS232 singleended serial signals to RS485 differential signals without external power supply. It harvests working power directly from the RS232 serial port, making deployment quick and convenient.

    Equipped with standard DB9 9pin COM connector and A/B screw terminal block, you can hook up RS485 bus cables easily for onsite installation. Pure hardware conversion, no driver installation required. Please be aware that this passive model is designed for shortdistance transmission; transmission quality may degrade with excessively long cables or heavy bus loads.

    It is widely used for equipment maintenance, parameter configuration and data acquisition for PLCs, digital measuring meters, industrial sensors and other serial devices. Compact form factor fits inside cabinets or workbenches. It is a costeffective serial conversion tool for technicians and DIY users working with legacy industrial serial hardware.
