Firstly I'd check which version of that motor you're talking about - there appears to be a 12V version (windings 50 ohms) and a 24V version (windings 150 ohms). It claims to be unipolar but I can't see how many wires it is.
Anyway with H-bridge drivers you only need to connect as if bipolar to the four wires that are at the end of the windings (there are some caveats if its a 5-wire unipolar motor as opposed to 6 or
And there are several sequences in which the windings can be driven (wave mode, full stepping, half-stepping). For lowest power consumption wave mode only energises one winding at a time (but has lower torque). full stepping energises both windings, half-stepping is a combination of the two to get twice as many steps.
