Warp Cable question

[FiXeL]

Ok, i've got a xmag and a warp feed. But what i don't have is the interface cable to hook the warp to the xmag's board.

But i do have a connector that fits onto the board, and a 2,5mm jack plug that fits into the warp. Can i just hook this up, or are there polarity issues? I don't want to fry anything by hooking it up in reverse polarity or something.

Yeah, i could get a cable but making it yourself is more fun. :)

Never mind... I made a cable and it works. The first attempt ended with a non responcive warp, but after reversing the polarity of the cable it worked fine.
