  • This USB cable adds a DB9 serial port to your computer or laptop. Works with MacOS X, Linux and Windows. Note that this provides (approximately) +-10V serial (RS232) not 5V serial (TTL), good for old devices like GPS, handhelds, programmers, etc with chunky DB9's on the side. Some cheaper RS232 cables 'cheat' and only give you 0-5V which wont work with some devices - this one has a true voltage doubler/inverter to make it more compatible.

    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.

    Cable Length: 1.37m / 54.25"
