UIC321H (USB to RS232 Adapter) is a highly reliable solution for serial communication, featuring full isolation between the RS232 port and the USB interface. Built around the Silicon Labs CP2102N chipset—one of the most robust and compatible serial conversion chips available—it ensures broad operating system compatibility, including with Windows, Linux (kernel 3.0.0-19 and above), Mac OS 8 and above, Android.

This converter provides 3000 VDC isolation for both power and data lines, supporting data rates up to 120 kbps. It also includes strong ESD protection on the TX and RX pins: ±8 kV for contact discharge and ±15 kV for air gap discharge. This makes it an excellent safeguard for both your USB port and connected serial devices against voltage spikes, static discharge, and transient surges.

Designed for industrial environments, this adapter performs reliably in electrically noisy conditions and where RS232 cables are frequently connected and disconnected. The durable cast metal enclosure offers added mechanical protection, and the unit draws power directly from the USB port—no external power supply required.
