compatability issue, or just me?

I just bought a new XT RD-M770-SGS and FD-770. when I went to hook up to my rear deraileur to my LX SL-M570-S shifters, they don't work right. Well, they work backwards to be exact.

is it me or a compatability issue that I didn't realize?

Thanks

To confuse us Shimano now make deraillieurs to pull up the cogs and deraillieurs to pull down the cogs. One is called a high normal and one is called a low normal although don't ask me which is which as I haven't had to find out yet. I'd say you have the opposite to what you had before.

and my front deraileur works and shifts fine, just the rear i'm having the problem with

the front will work anyway, they're all the same....

so the rear is shifting backwards, you say; but are the shifts happening properly? if so, don't sweat it; that's what happens when you mess with high or low-normal crap. if it doesn't shift cleanly, even though it's backwards, see if it can dial it in; otherwise, it's shop time.
