5. PIN ASSIGNMENTS
A 12 pin pluggable terminal strip connector JP1 provides power and the step and
direction control functions for the module. All of these signals are optically isolated.
Open-collector drives are required to provide pulses for Step, levels for Direction
Disable, and Zero Set. The common +ve supply can be +ve 5 to 30 VDC with respect
to the signal input; however if the supply is greater than 5 VDC then a resistor must
be inserted in series with each signal line to limit the current to 10 mA.
