USB to RS-232 adapter for legacy serial devices

The UT-8823F connects equipment with a DB9 female port to a computer through a USB-A male plug. It suits engineers, technicians and hobbyists who maintain industrial controllers, networking gear or point-of-sale hardware that still relies on RS-232 communication. The 1.5 metre cable length gives enough reach for bench testing or permanent installation without excess slack. No external power supply is needed.

Automatic flow control removes handshake

Built-in I/O circuitry detects and manages data direction without RTS, DTR or jumper settings, so the link works immediately with existing terminal programs and custom software. The adapter supports asynchronous point-to-point operation at baud rates from 300 to 460800 bps, automatically matching the serial port speed. ±15 kV electrostatic protection on the interface helps guard connected hardware during hot-plug events.

DB9 female to USB-A male with 1.5 m cable

This single cable replaces a separate converter dongle and serial lead, reducing failure points in the signal path. The RS-232 end is rated for transmission up to 5 metres, while the USB segment follows standard length limits. Compatibility spans Windows 95 through 11, macOS and Linux, covering virtually any host used for legacy equipment support.

Questions about this item

Does the DB9 female connector on the UT-8823F need periodic cleaning or replacement?

The DB9 female connector has ±15KV electrostatic protection and requires no scheduled maintenance; keep it free of dust and avoid bending the cable sharply.

What is the maximum baud rate the UT-8823F can sustain continuously?

The converter automatically detects serial signal rates up to 460800bps and supports asynchronous point-to-point operation at that speed.

Does the UT-8823F draw enough power from the USB-A port to run warm during all-day use?

It operates without an external power supply, drawing only USB bus power; the zero-delay automatic send/receive circuitry stays cool under normal loads.
