## Customer Reviews

### ⭐⭐⭐⭐⭐ Exactly What I Needed for Legacy DB9 RS-232 Interfaces
*by C***® on January 3, 2013*

I do software development on a lot of embedded systems ranging from tiny PIC and AVR MCU based device to big ARM and PowerPC MPU based systems. Some of the older systems export the processor logic-level serial port out through a DB9 connector with RS232 signal levels. This little gadget is inexpensive enough that I buy one and just screw it onto the board, more or less permanently converting the board to a USB-serial interface. The gadget is barely bigger than a bare DB9 connector hood. And since it uses an FDTI chip inside, it works flawlessly. (I've given up using any USB-serial adapter that doesn't use a chip from FTDI because the rest are all crap.) So now when faced with an older DB9 RS232 port, I just automatically order one of these from Amazon.com and eliminate that little detail from my worry list.

### ⭐⭐⭐⭐⭐ Just works
*by C***C on September 22, 2011*

This device just works. Plugged it in to my Windows 7 x64 notebook and within 10 seconds it was ready to use on Com 3. It then allowed me to set it to Com port 1, which makes it a bit easier to use it with some applications. In short, good product for my needs.

### ⭐⭐⭐⭐⭐ Works fine with OSX
*by B***T on May 13, 2011*

I've tested it so far with Mac OS X 10.6 and 10.4.11, using the current driver from FTDI's ftdichip site. Works just fine with my microcontrollers using ZTerm. I have additional plans for it, and am confident it will work as well with those. Heck of a deal at this price!
