I recently had the need for a reliable USB to RS-232 serial adapter, and I was thrilled to find the TRENDnet TU-S9 in my search. The first thing that caught my eye was its NDAA compliance, which is a crucial factor when working with government customers (US and Canada only). This feature allows me to plan and install networking solutions with confidence.

As for compatibility, the TU-S9 supports USB 1.1 and is compatible with USB 2.0 and USB 3.0 ports, making it a versatile option for various devices. The flexible 540mm (21 in.) USB 2.0 cable accommodates most installation scenarios, adding to its adaptability.

The setup process was incredibly straightforward. In just seconds, I had the cable connected and ready to go. It’s a plug-and-play device, so no additional drivers were required.

One of the standout features of this product is TRENDnet’s Manufacturer Protection. With two years of coverage, I feel secure knowing that if any issues arise, they will be addressed promptly. Their team of advisors, support, and tech experts are English-speaking and available during normal business hours.

I was able to connect RS-232 serial devices such as modems or printers using the widely supported USB standard found in most laptops and desktops today. The TU-S9 proved itself to be a reliable connector throughout my testing period.

Lastly, it’s worth mentioning that the cable length is 25 inches when including the RS-232 (9pin) and USB Type A connectors. While this might seem short for some users, it worked well in my specific setup.
