Input Option Header
The R701P has no internal jumpers for input options. The inputs can be driven by a source where
+5V, + 3.3V or ground is only available.
Using +5V, Common Ground, and Disable for Optos
Your negative 5V supply will connect to the “+5 VDC” line, Pin 10. The negative side of your step
pulses should then connect to your “Step” line, Pin 9. The positive side of your +5V and the positive
side of your step pulses should be tied together.
To disable the drive, connect the disable pin to Pin 12, the end of the current set resistor pin. To
change direction of rotation, connect the direction pin to the +5V and + step pulse connection.
