Two-port RS-232 expansion over USB 2.0

The UOTEK UT-8812 converts a single USB-A 2.0 connection into two DB-9 serial ports for industrial equipment. It draws power from the host and requires no external supply, making it suited for field service and bench work.

Engineers maintaining legacy machinery.

Technicians who need to talk to PLCs, meters or older CNC controllers from a modern laptop will find the dual-port layout convenient. Users who require faster throughput or more than two simultaneous serial links should consider a different interface class.

Dual 921.6 Kbps channels with 1.5 m reach

Each port handles 300 to 921.6 Kbps with automatic baud-rate detection and hardware flow control. The 1.5 m cable and 5 m RS-232 transmission limit keep the adapter practical for cabinet-to-PC runs, while ±15 kV ESD protection guards the ports in noisy environments.

この商品に関する質問

My PC only has USB-A 2.0 ports — will the single USB-A 2.0 male plug on the UT-8812 work directly?

Yes, the converter has one USB-A 2.0 male connector that plugs straight into any USB-A 2.0 or 1.1 port without an extra adapter.

I still use legacy RS-232 gear with DB-9 connectors — can the UT-8812 drive two of them at once?

The cable ends in two DB-9 male ports, each supporting asynchronous point-to-point communication at 300-921.6 Kbps, so you can run two RS-232 devices simultaneously.

How do I confirm the UT-8812 is active after plugging it in?

Built-in power and data-flow LEDs light up to show the link is live and traffic is moving on each serial port.
