USB to RS232/485 Converter

The KEHIPI USB to RS232/485 Converter uses an original FT232RNL chip to provide stable serial communication between a USB host and legacy RS232 or RS485 equipment. It suits engineers, hobbyists and integrators who need reliable data transfer for industrial, automation or development tasks across multiple operating systems.

Check host port and target interface

Verify that your computer has an available USB port and that the target device uses either RS232 or RS485 signalling. The onboard switch selects the active protocol and a second switch enables or disables the 120R termination resistor on the RS485 line, so confirm the required configuration before connecting.

Protection features and status indication

An ABS enclosure houses TVS diodes, a self-recovery fuse and protection diodes to suppress surge voltage and guard against over-current or over-voltage events. Three LEDs show power, transmit and receive activity, giving immediate visual feedback during installation and daily operation.

Fragen zu diesem Artikel

Does the converter come with a USB cable, or do I need to supply my own?

The adapter is a complete unit with an integrated USB connector and terminal blocks for RS232 and RS485 wiring; no separate cable is required.

The product lists both RS232 and RS485 — how do I select which one to use?

A hardware switch on the board toggles between the RS232 and RS485 interfaces, and a second switch enables or disables the onboard 120R termination resistor for RS485.

What does the FT232RNL chip actually do for me when the converter is plugged into a Windows 11 PC?

The FT232RNL handles USB-to-serial conversion, so the device appears as a standard COM port in Windows 11 without needing extra drivers, letting any serial software talk to your RS232 or RS485 equipment.
