USB/Serial Converter – PL2303. This USB cable adds a DB9 serial port to your computer or laptop. Works with MacOS X, Linux and Windows. Note that this provides +-12V serial (RS232) not 5V serial (TTL), good for old devices like GPS, handhelds, programmers, etc with chunky DB9′s on the side.
These are tested and work great with bit-bang serial devises MiniPOVs, DASA programmers and Serial SpokePOV adapters – note that they are slow in comparison to hardware serial ports due to the high overhead of USB.
They are super fast for every day USB-Serial conversion. Uses the PL2303 chipset. Comes with a CD but we strongly suggest using the most recent drivers from the Prolific Website if you’re running windows and the ‘fixed’ driver for Mac OSX.
