Sorry; I took some more time looking at both cards. On the IDE -> CF card, the IDE (male) socket has a small arrow which points to the first pin on the socket.
On the SCSI to IDE card, the IDE (female) adapter is fully numbered from 1 to 40 (very small print).
However it is impossible to connect the pin pointed by the arrow on the IDE -> CF adapter directly in the whole labeled '1' in the SCSI -> IDE card!
Is this normal? Sorry if the question may sound stupid; unfortunately I do not have any experience on these things
