INCORRECTThe IDC connector pinout does not seem to be correct. Isn"t pin 1 usually (indicated by *):APPROVED
CORRECTAPPROVED
INCORRECTArent the IDC headers usually noted with pin 1 to the right of the polarization key, looking at the top of the male header. Top right, as pictured, pin 10 should be labeled pin 1.
Another item that may create confusion is that some manufacturers decide to label the remaining pins across and then back down to the 2nd row (starting out right to left just like the top row). This becomes ambiguous when others decide to keep on jumping with the pin numbering inbetween the rows, such that one row contains odd and the other row contains the even numbered pins. Just depends who felt like it, or what the policy was at the time...
