Parameters:

Session - The session variable obtained from the PICMLX_Connect call

CardNum - card number

InSub - input sub-unit number

Data - pointer to variable to receive result

DataLen - length of the above array in BYTES (Note - BYTES not DWORDs !)

Input sub-units do not exceed 32 bits in size, so an array is not necessary to receive the result.
