Why does it need 4 inputs? Do you mean it needs 4 wires connected,
or 4 signals? What type of input is it requiring, a voltage or a current?
Many drivers have opto-isolators at the input to avoid electrical noise
problems,
and require a current to activate the opto-inputs. So, you might connect
#4(+) and #5(+) to a source of +5 V from your computer (pin 1 of the
15-pin game port is +5 V), and then you only have #2 for CW and #3 for CCW.
These outputs would probably need to remain high (+5V) for no step,
and pulse low (~0V) to step.
