| | 24 | === Old Power Box for MACRO/Super-K === |
| | 25 | |
| | 26 | This is a Bud box with a 12V power supply, a PCB and 3 connectors (DB15, DB25 and 20 pin header). |
| | 27 | It provides power switching electronics for a 5V motor. |

| | 52 | :http://joule.bu.edu/~hazen/SteppingMotors/stepper1.gif |
| | 53 | |
| | 54 | This is the standard step sequence: |
| | 55 | |
| | 56 | || ||A||B||C||D|| |
| | 57 | ||1||ON||-||-||ON|| |
| | 58 | ||2||ON||-||ON||-|| |
