What SCSI cable do I need for a Dreamcast?

Okay I'm still working at getting my Dreamcast Dev set up. I bought an ADAPTEC AHA-2940U2 SCSI ADAPTER PLUS FUJICURA 68-PIN SCSI CABLE. I think the adapter is what I want but the SCSI Cable doesn't do me any good does it? What cable do I need? I also bought a SCSI 1 Terminator and I guess I need SCSI 2? I should have one of them on the way now. But the SCSI 2 cables that I have seen are both SCSI 2 on both ends. I think I need a 68 pin to a 50 pin SCSI 2 cable maybe? Any help would be greatly appreciated. I'd love to see if there is anything on my hard drives.
Thanks!

 

Correct, you need a 68 pin to 50 pin converter, or you can just buy a 68 pin to 50 pin cable. That's what I did. Still working on getting mind setup.
