Quick questions about SX KeyRing...

Hello,
I just received my SX KeyRing this morning and had a few questions about it:
1 - It appears that the silkscreen is backwards where the SX-Key plugs in. I can follow the traces and used an ohm meter to confirm that I should not reference the silkscreen and the component side of the SX-Key should be up instead of what the silkscreen shows.
2 - The connector looks like it is center + and the outside GND. Can someone confirm the specs for the power adapter?
3 - Was there a datasheet online just for the SX KeyRing? There no longer seems to be any reference on the Parallax site for it.

1. You are absolutely correct.
2. Correct again. I use a 9-ish volt center positive wall wart. Works fine.
3. Can't help you here.
