Scanner is not connected

Step:
1. Check cable connections.
2. Check to see if a SCSI terminator is required.
3. Check to see if the READY indicator and the scannig [sic] lamp are both [sic] stay lit.
4. Make sure there is no SCSI ID number conflict.

** Make Sure the scanner is on the list of the system device manager.

Um... How the hell would I know if a SCSI terminator was required? And if I did know how to determine this, would I know what one was or where to get one? Or what to do with it? And what if the scanner is not on the list of system device? How do I get it there?

Damn second hand hardware. I mean, it's free, so I shouldn't complain about the hassle. And I knew it might not work, so I shouldn't complain about the lost 45 minutes. But 45 minutes is a big chunk of my evening.
