 Which pins for MIDI?

Since the headers in the schematic for the Edge are not oriented in the same way as on the board, I need a reference point. Which pins in block 102 are VCC, GND, and TX?

Also, in the MIDI schematic, we have VDD, while in the DSerial one we have VCC. Are those the same thing? All I found on the internet were semantic arguments, so I'm guessing they're the same.

Thanks, Ian

The pinouts are here:

Specifically you would be using pins 1,2,3 on IO2 (that is Input/Output Port 2, not 102)
1: GND
2: VDD / VCC
3: TX

Pin 2: VDD is in the corner of the board. Pin 1 is on the edge, one row closer to the DS Card edge. Pin 3 is one pin from each edge.

Code:
Bottom               Top
----------    ----------
IO2 08642|    |24680 IO2
    97531|    |13579
IO1 08642|    |24680 IO1
    97531|    |13579

In this case, VDD in VCC are the same... He just used them interchangeably in his schematics. (What you want is basically just 3.3v, and that's what VDD supplies)
