Pin 1 of the connector can be identified with a white dot which is located at the bottom left most pin of the connector when looking at the platform from the bottom side with the Compact Flash socket (X3) to the right of the board. Pin 2 is directly above pin 1, such that all of the even pins (2 through 40) are arranged on the top edge of the connector (from left to right), and odd pins (1 through 39) are arranged along the bottom side of the connector (from left to right).
The above image provides an illustration of the connector pinout. For detailed information on individual pin function, please see section 5.3 in the MECS Tellurium datasheet:
