### Notes

- The pin numbering for the PSX connector presented here is reversed from the numbering on the NTPad XP web page. Also the original web page shows the connector looking into the CONNECTOR ON THE CONSOLE.
- See the Powering PSX pads page for details on how to provide the +3.5v and +7.6v required by the PSX pads.
- General notes about interface construction
- This interface supports configurable timing parameters - see Changing timing parameters on how to change these values and Playstation timing parameters for their meanings.
- PPJoy has a debug mode for playstation interfaces. See Setting PPJoy global options for a description of this feature and how to active it.
