Looks good.

I think there is a typo in there. That should be pins 5 and 9.
I'm using pins 9, 8, and 7 as per Stewart's message that started this
discussion.
> 3 and 7 ground
Pins 1, 2, and 6 seem not-connected. (That's using a scope without a ground
clip. I see slight fuzz on pins 3 and 7, nothing on 1, 2 and 6.)
The above is on J8, Diagnoistic.
--------
J6, RS422/PPS has the same (5, 9) TX pins. If you shift the cable over there
it gets a line each second. This can be handy for checking that direction of
your setup.
Pins 1 and 6 are the PPS pulse. 400 microseconds wide. It's not active on
my box that's in STBY.
Pins 4 and 8 look like inputs. Does anybody know what you can send in there?
