Not a stock method... You see, Victor 884s take a PWM input using a standard 3-pin PWM cable. The NXT outputs its (whatever type of) signal on a relative of an ethernet cable. So you'd have to figure up a new connector. It's doable (teams have interfaced an NXT to the robot controller) but it isn't built in. I don't know what sort of pin mapping you'd need to do, though I'm sure someone might be able to help.
