It's the same helicopter as yours and the Walkera 22E. Also see this post:

I don't know why they supply that cable. I think it's left over from one of the Walkera 4-channel heli's. See this thread for how to make a cable that connects to your parallel port:

You can also search the forum for how to make a cable that connects to your sound card. Search for FMS and SmartPropoPlus, or I think you can find everything you need here:
