There is a bit of confusion in
Tracy EC2 manual. It might seem like  a minor
point but you are going to need all the help
you can get.

In the picture of the box pin 1 37 pin connector is on the lower left.
In the diagram top of page of the mating male connector pin
1 is on the upper right. Had me scratching my head for
a few seconds. Tracy makes a note of it but it added
to the confusion for me. The numbers are also
on the connector but an old guy like me cannot see
them :)


I redid the connector diagram with the correct orientation
in the attached jpg.
