Overview

The 1P3FP-USB-SERIAL 1 Port USB to Serial Adapter lets you add an RS-232 DB9 serial COM port to your laptop or desktop computer, allowing it to control and communicate with a serial peripheral device.

Accessible Connectivity The USB to RS232 cable is a convenient connectivity solution that bridges the gap between current and legacy technologies. The small footprint, data rate of up to 921.6 kbps, and 3 ft (0.91 m) cable length makes it the ideal solution for the IT industry, point of sales (POS), industrial applications, AV, and office setups.

Connect with Ease This adapter cable allows you to add an RS-232 DB9 COM port by connecting it to the commonly found USB Type-A port, located on your host device. This USB 2.0 converter is compatible with other USB revisions. It supports Windows, macOS, and Linux (including the latest versions) for maximum compatibility.

1P3FP-USB-SERIAL is backed for 3-years by StarTech.com, including free lifetime 24/5 multilingual technical assistance.
