UOTEK UT-810N USB to RS-232 converter

This UOTEK UT-810N cable converts a USB-A port into a DB9 male RS-232 serial connection. It spans 4.92ft and includes a magnetic ring for signal stability. The adapter draws under 200mA at 5V and operates from -25 to 70°C. Drivers cover Windows 2000 through 10, Mac, Linux and CE.

Suits legacy serial gear; not for high-speed links

Engineers maintaining PLCs, industrial modems, barcode scanners or older networking kit gain a reliable COM port without internal cards. Auto direction control removes manual flow-setup steps. Buyers needing throughput above 115200bps or cable runs beyond 15m RS-232 should look at other interface types.

Baud rate range 300-115200bps auto-detected

The single spec that decides fit is the supported baud window of 300 to 115200bps with automatic detection. Match this to the target device’s serial setting; if the equipment demands a fixed rate outside this band or a proprietary protocol, the converter will not establish a link.

Questions about this item

What USB port type on my computer is needed for the UT-810N converter cable?

The cable plugs into a standard USB-A port that supplies USB 2.0 full-speed signalling and 5 V power at under 200 mA.

Will the DB9 male connector work with legacy RS-232 equipment that uses hardware flow control?

Yes, the adapter carries TXD, RXD, RTS and CTS lines and auto-controls data direction at 300 to 115,200 bps.

How can I confirm the link is active after plugging in the 4.92 ft cable?

The OS will enumerate a new COM port and the RS-232 side will transmit up to 15 m with ESD protection rated at 8 kV contact and 15 kV air discharge.
