Part Number: DAC34H84EVM
Other Parts Discussed in Thread: DAC34H84

The module, I bought( DAC34H84 EVM(Rev D), is not  compatible mechanically with FMC-DAC adapter. It is impossible to connect boards to each other.

Are there many versions of the FMC-DAC adapter?

    Iouri,
    the two EVMs should be compatible. There is only one version of FMC-DAC adapter. If you can post a picture of the difficulty in making the mechanical connection it will be helpful to understand the situation.

    Dear Kang,

    The nail (number 1 in the picture) cannot go through the hole (number 2 in the picture), because the distance between the nails is shorter, than the distance between the holes.

    Another problem is, that a piece of plastic (number 3 in the picture) prevents connecting the boards(place number 4 in the picture). I had to remove a piece of plastic in the connector of the

    FMC-DAC adapter (again place number 4) and modify nails in order to connect the boards. The boards work fine, but such a kind of connection is not reliable.

    Sincerely,

                                  Iouri.
