No, it is just a serial cable.  It passes frequency commands and so 
forth if you use it with a program like Ham Radio Deluxe.

You also need two standard 3.5mm stereo patch cables to go between your 
computer's sound card LINE IN and LINE OUT and the K3's connectors. 
LINE OUT of the computer to LINE IN on the K3, and LINE IN to the 
computer from LINE OUT from the K3.

Using two audio cables like this, a serial cable, and Ham Radio Deluxe I 
can operate the digital modes, including transmit and receive, from my 
computer.

PS - I would expect FLdigi and MixW to work as well, but have not tried 
them so cannot speak from experience.
