USB to RS232/485 Serial Converter

The MCDODO USB to RS232/485 Serial Converter uses an original FT232RNL chip to provide stable serial communication for developers and engineers. It bridges modern USB ports with legacy RS232 and RS485 equipment across Windows, Mac, Linux and Android platforms. The board suits industrial automation, IoT edge projects and device debugging tasks.

Dual protocol support with configurable termination

The converter handles both RS232 and RS485 protocols selectable via an onboard switch for flexible deployment. An integrated 120R terminal resistor on the RS485 interface can be enabled or disabled by switch to match bus requirements. This single unit replaces separate adapters for mixed-protocol environments.

Protected circuitry in a compact ABS case

Onboard TVS diodes and a self-recovery fuse suppress surge voltages and provide over-current and over-voltage protection for reliable operation. Three status LEDs indicate power and transceiver activity for quick diagnostics. The ABS enclosure makes the module portable and durable for bench or field use.

商品問答

Will the FT232RNL chip work with my Windows 7 machine alongside newer PCs?

The converter supports Windows 7, 8.1, 10, 11, Mac, Linux and Android, so the same FT232RNL device can move between legacy and current systems without driver changes.

How do I verify the RS232 and RS485 links are active after connecting?

Three onboard LEDs show power, transmit and receive status; the RS485 terminal resistor is enabled by its switch and the mode switch selects RS232 or RS485, giving immediate visual confirmation.

Does the ABS case include the USB cable and terminal plugs, or must I source them?

The board ships inside an ABS protection case with the FT232RNL chip, TVS suppressor, self-recovery fuse, protection diodes, 120R RS485 resistor and mode switches already fitted; a USB cable and wiring for the terminal blocks are not included.
