Connecting IDE -> CF card to SCSI to IDE card

[Thomas]

You have to find out the right way, otherwise it will fry.

Check if there are labels on the boards. Pin 1 should be marked somehow (a 1, a dot, an arrow, something like that).

[Thomas]

If the connectors match, then it should work. The arrow does not necessarily point to pin1 but only to the end where pin 1 and 2 are.

If you have a spare 3.5" HDD, you should compare the connections. The SCSI-IDE adapter usually fits exactly behind the HDD. The HDD then has the reverse protection notch at the top and pin 1 is on the right.

I've attached a photo. I don't have a SCSI-IDE adapter at hand, but perhaps the cable is sufficient. You see that there are two reverse voltage protections: a notch and a missing pin. The HDD has the notch on the top and pin 1 on the right. The cable has the opposite of the notch on the top and pin 1 (the red line) on the right (if you turn the cable to connect it, pin 1 is on the right, too).

Bye,

Don't you have a manual for the device ? A booklet or something ?

Perhaps the arrow points to pin 40.

Or they mounted the connector upside down by accident.

Or the arrow does not belong to the IDE connector.

[Thomas]

At the bottom of the IDE -> CF adapter there is a (white) 4 pin socket. What is it and do I have to fit anything there?

It's probably the power connector. You should connect a floppy power cable there.

See the attached photo. On the right there is the power connector and a matching cable.
