TMDSCNCD28379D: Pin 1 on HSEC card edge connectors.

Part Number: TMDSCNCD28379D
Other Parts Discussed in Thread: C2000WARE

Hi, 

Looking at the 180-pin HSEC card pinout .PDF file (TMDSCNCD28377D_180cCARD_pinout_R1_3.pdf), within the C2000ware set of documents, I am seeing that on the 60 position (120-pin) connector, "pin 1" is defined as being on the "shorter" portion of the connector (that is, the side of the gap with 28 positions). The same also goes with the docking station pinout.

This is inconsistent with pin 1 designation on the part used in the BOM for the card edge connector on the docking station (HSEC8-160-01-L-DV-A-BL), Where pin-1 seems to be on the "bigger" portion of the connector (that is, the side of the gap with 32 positions.

Would it be possible to get confirmation on this observation? 

Thanks!

    Julien,
    The statements in the pinout file are in reference to the controlCARD's design as well as the controlCARD standard. This does not refer to the Pin1 of the 'HSEC8-160-01-L-DV-A-BL' connector.

    As you have correctly pointed out Pin1 of the connector is not Pin1 of the controlCARD. I recognize that this is potentially confusing, but please understand that in all documents we do not refer the the pins of the 'HSEC8-160-01-L-DV-A-BL' connector.

    Hi Cody,

    Thank you for the prompt reply. I understand this is not a mistake in documentation, but needed to confirm my understanding of the card's layout.

    Regards,
    Julien
