Industrial USB-to-Serial Bridge

The UOTEK UT-8801 converts a USB 2.0 port into a standard DB9 male RS-232 interface. It supports baud rates from 300 bps up to 460.8 kbps and handles auto-handshake protocol without external power. Built-in ±15KV ESD protection guards the link in harsh environments. The 4.92ft cable reaches equipment mounted inside cabinets or panels.

Replaces Legacy Serial Ports

Modern PCs lack native RS-232 ports, so this adapter bridges the gap for PLCs, HMIs, barcode scanners and older industrial gear. The jump is worth it when software expects a physical COM port and USB virtual COM drivers satisfy the application. Zero-delay auto-transceive circuitry keeps timing-sensitive protocols stable. Wide OS support from Win2000 through Windows 10, plus Mac and Linux, eases deployment.

Suits Field Engineers and Integrators

Technicians maintaining factory automation, telecom or POS systems gain a reliable serial link without hunting for legacy hardware. Buyers who need galvanic isolation, multi-port expansion or USB 3.0 signalling should look at other solutions. The single DB9 male connector limits use to point-to-point connections. Operating range of -40 to 85 °C and 5 to 95 % humidity fits most indoor and sheltered outdoor sites.

Questions about this item

Does the 4.92ft cable with DB9 male connector reach my equipment rack without strain?

The 4.92ft cable length and DB9 male connector are designed for standard serial device spacing; measure your rack distance to confirm fit.

Which driver must I install before plugging the FTDI-chip converter into a Windows 10 USB-A port?

Install the FTDI VCP driver for Windows 10 first, then connect the USB-A plug; the converter uses USB 2.0 and draws power from the port.

How often should I inspect the ±15KV ESD protection and cable jacket for industrial-environment wear?

Check the cable jacket and DB9 pins quarterly in harsh settings; the ±15KV ESD rating protects the chip, but physical damage requires replacement.
