Wiring HintsCommon isnt always Ground!In this case we are wiring ‘active low’. That means the driver board steps when it senses a pin pulled low, you will notice that the power setting on the breakout board is set for common +5v, which is provided to the CW+ and CP+ terminals on the 4030 driver module.
C10 Breakout board power sourceThe buffer chips on the C10 require +5vdc for operation, hence the additional power supply. A voltage regulator circuit such as a 7805 can be used instead. Additionally, the C10 requires +5v on the enable input, otherwise the buffer ICs will not pass data from the PC.
E-Stop: Normally closed?If possible, a normall closed button pulling an input high should be uvsed for an E-stop. This way, if the power to the machine fails, the PC will see the input pin go low and report an emergency stop.
C10 Breakout Board JumpersJP1 selects the direction for parallel port pins 2 through 9. This is useful when using multiple breakout boards and parallel ports.
