USB to Serial Converter Cable

The TRENDnet TU-S9 connects RS-232 serial devices such as modems or printers to a USB Type-A port on a desktop or laptop. It installs as a standard Windows COM port with full modem control signals. The adapter works with USB 1.1, 2.0 and 3.0 ports.

Windows and Mac OS Support

Drivers cover Windows 10, 8.1, 8, 7 and Mac OS 10.11 down to 10.6. Plug-and-play setup lets the cable be recognised in seconds without extra configuration. This breadth keeps legacy hardware working on modern and older operating systems alike.

500 kbps Maximum Data Rate

The link tops out at 500 kbps, so it suits equipment that communicates at or below that speed. Devices needing higher throughput will not perform correctly. The 21-inch cable length fits typical desk or rack installations.

Questions about this item

Will the USB connector or DB9 plug wear out after frequent insertion?

The cable uses standard USB Type A and RS-232 9-pin male connectors rated for typical mating cycles; avoid excessive force when plugging or unplugging.

What limits throughput during continuous data transfer?

The adapter caps serial data rates at 500 kbps, so sustained throughput cannot exceed that figure.

Does the adapter draw enough power to heat up during all-day operation?

Maximum draw is 500 mA from the USB port, and the operating range is 0–40 °C, so it stays cool under normal loads.
