This USB to Serial converter allows you to connect a RS-232 serial device such as a modem to a USB port on your Desktop or Laptop PC. Connect a RS-232 serial device such as a modem to a USB port on your computer. Easy installation with Universal Plug and Play. Compliant with Windows 7/Vista/XP/2000/ME/98SE and Mac OS 10.1~10.6 . 2-year limited warranty.
This USB-RS232 converter is based on the PL-2303 chipset and is one of the few with true cross-platform support. Other models are lacking drivers for Mac, Linux, Vista/7, and 64-bit flavors of Windows. If you need something that'll just work no matter what you're running get a USB-RS232 adapter based either on the PL-2303 (like this one) or the FTDI chipsets. If you can't get this to work out of the box, just Google for "PL-2303 <your OS> drivers" and you should be good to go.
There are other converters out there that provide more reliable data transfer at higher speeds, but this is a great buy for the money and will suffice for just about any task you need it for.

Connected 4 of these to the same computer to run DNS. Till now works 24/7 for a couple of monts without any problem neither resouce conflicts (other SYBA hardware gave me tons of problems). Didn't have even to install the driver. WinXP recognized it as "Prolific USB-to-Serial Comm Port (COM3)" to (COM6). Recomended product.

We have a half-dozen of these TrendNET TU-S9 adapters in our environment; we use them for connecting to RS232 devices. We selected them because they support both Windows and Macs. They work great.
With the release of Mac OS X Lion (10.7), the TrendNET adapters no longer work with TrendNET's own drivers. I submitted a help desk ticket to TrendNET's tech support inquiring about the status of drivers for Lion, and received the following response: "We do not have drivers for the MAC os [sic] 10.7 and do not have any current plans to support the 10.7 OS."
But fear not: It's easy to get these working with Lion. The chip inside this adapter is a Prolific 2303; there are several USB-to-serial adapter that use this chip. Prolific itself produces a 64-bit driver for this chipset, and lo, the TU-S9 works once it is installed. The driver can be found by Googling 'PL-2303 driver'. It's the file labeled `md_PL2303_MacOSX10.6_dmg_v1.4.0.zip' on the resulting page (or was at the time I wrote this review).
I just tested it with my TU-S9 and it works once I install this driver. Enjoy!

Purchased this to replace an older iogear USB to serial adapter that refused to work with 64 bit Windows products. I had to keep a separate 32 bit Windows partition to use whenever I needed to utilize the serial adapter. Well I'm pleased to say this is no longer the case and I was able to free up some needed space on my laptop! This works great with both Vista 64 bit and Windows 7 64 bit. I'm a Nortel Field Engineer and use this to communicate with various Nortel/Bay Networks routers and switches without trouble (Yes, it works with Cisco products as well). Works like a charm paired with TeraTerm and/or plain ole' HyperTerminal.
There's no difficult installation either, just run the setup on the included micro-cd and you're up and working in no time!
Kudos to TRENDnet for making such a great product at a great price!

This Adapter works well with Linux, OS X, Windows (but not Vista ), and BSD OSs or any system with Prolific USB-serial drivers .
The only bad thing about this product is that is USB 1.1 thus if you use it with a USB 2.0 hub you will slow all the other devices on that HUB down to 1.1 speeds.

You have to install the driver on the CD first but once you do it works great with Mac OS X (10.5). You do not have to reboot after the driver install even though it is really insistent about it.
I'm using a shareware program called ZTerm to talk through it but it just shows up as a character device so you ought to be able to use it with anything. It also shows up as a device in the system network settings if you are into that kind of thing.
