Add a serial port with this USB C to serial with COM port retention

This USB-C to serial adapter lets you connect your USB-C devices to your legacy serial equipment. It converts a USB-C port on your laptop or computer into an RS232 DB9 serial port with COM port retention. This gives you a cost-saving and convenient way to connect to serial devices such as point-of-sale terminals, serial modems, industrial equipment, and a wide variety of other RS232 peripherals.

Connect with ease

The RS232 adapter cable is compatible with Windows, macOS and Linux operating systems, which makes it easy to integrate into mixed environments.

Built-in convenience

A time-saving and convenient USB/serial solution, the adapter retains assigned serial COM port values in nonvolatile memory, allowing the same values to automatically be re-assigned to the adapter serial port if disconnected and reconnected, or disconnected from one USB port and installed in another.

The USB-C serial cable also supports advanced features like remote wake-up and power management control.

The ICUSB232PROC is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Returns FAQs

What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked items.

How do I go about returning my order?
Please contact us via our contact page with your order number. We will provide you with an RMA number and return instructions, including your return deadline and whether a freepost label applies to your order.

Do I need to contact you before returning my order?
Yes, to obtain an RMA number before sending anything back.

Does my item have to include its original packaging?
