Rev D Demo schematic

Chris or Beau·or Paul - why is Pin 9 of the VGA connector tied to 5V on the Rev D schematic? · Pin 9 is NC.

Pin 9 is used as a 5V accessory supply (ie 3D shutter glasses). It will be ignored by most every monitor. It's there in case someone wants to use something that requires it. Otherwise, it should be innocuous.

Chip, there is no way to access that.· Pin 9 on the male DB15 VGA connector is missing - just a blank space there.

Sid,
If you had a device that needed the 5V, it would be there.
