I was reading Tracy's EC2Ainstallation guide pdf
and ran across this illustration of the back side of
a DB37 male connector on page 20 and on page 25 of the
EC2 manual. Then I checked the position of pin
1 on the female mating connector on top of the EC2.
Opps!!! Something did not look right.

Pin 1 was actually on the left on the EC2 and it was on
the right in the illustration. In any even I changed the
illustration and here is the corrected version.

Might seem like a minor point to us old sparkies but
a newbe might be more confused than he is already :)

Seems to be a problem of sexual identity.

Don't forget that there is a male and female plug. You are
soldering/crimping to the non-active side :-*. Additionally when you do
your work, it is easy to forget which side you are working on.

Mixing them up is very easy, especially if you are not sure about which
side Tracy was looking at when he assigned the numbers in his
drawings/schematics/lists.

THAT'S WHAT THE NUMBERS ARE EMBOSSED ON THE CONNECTORS FOR.

Additionally, make sure that you have the right connectors on the
ends.-- and easy mistake to make (I hesitate to become sexually
specific). I think that the EC-* has female connectors on it's case and
that the panel controller also has female connectors. Thus you need two
males.  Don't take my word for it' however, look for yourself.

The EC 1, 2 and 3 have female connectors.
Pin 1 on a male is pin 1 on a female.

We are not talking about the "panel" (PCM) connector yet :)
