    USB to RS232/RS485 Bidirectional Serial Converter

    USB To RS232/485 Serial Converter, Onboard Original FT232RNL Chip, Multiple Devices Applicable, Multi-OS Compatible



    • Adopts original FT232RNL chip, fast communicating, stable and reliable, better compatibility
    • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
    • Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shockproof performance
    • Onboard RS232/485 communication switching circuit, configured by the switch
    • Onboard 120R terminal resistor on the RS485 interface, enabled/disabled via a switch
    • 3 LEDs for indicating the power and transceiver status
    • Adopts ABS protection case, compact size, portable and easy to use, cost-effective
