CM1-86DX2
3.11 MiniPCI-Express Interface (X10)
Connector type: MiniPCIe/MiniCard socket/mSATA socket
The MiniPCIe-Card-Socket can also be equipped with an mSATA-Card. Therefore, the mSATA-
Card has to pull Pin 43 up, while Pin 21 or Pin 51 has to be pulled down.
If Pin 43 is pulled low, while Pin 21 or Pin 51 is pulled low, the normal mini card functionality is
maintained.
In cases where the auto detection of the card type fails, you can force the mode of operation
with the jumper header X20.
