EVMK2H: Differences between EVMK2H and EVMK2HX

Part Number:EVMK2H

I see there are two versions of this EVM:

EVMK2HX: 66AK2H Evaluation Modules - With Encryption

EVMK2H: 66AK2H Evaluation Modules - Without Encryption

Can anyone explain the differences between them?

I wasn’t able to find anything in the Advantech documentation on the differences.

Can the EVMK2HX be used with or without encryption (equivalent to the EVMK2H)?  We don't know yet if we'll need to utilize encryption or not.

Thanks,
