A fortuitous topic: 
I am much less knowledgeable about SCSI than Damien and I am 
attempting to install a UMAX UTA-11 SCSI scanner to my Debian 
machine.
I have an internal scsi card (not an Adaptec 2940) installed, the 
card is attached to my computer with a small scsi connector, a 
5+/-  ft cable with a parallel connector on the other end going 
into a female parallel port on the scanner.
There is a short (12 inch ) cable going from the scanner body to 
the scanner cover.  The scanner body end is a printer type 
connector, but 1/2 inch or so shorter than a standard printer 
connector and the connector going into the cover is a parrallel 
connector.

I do not know anything about terminators or whatever.  Do they go 
in line with one of the cables on the scanner?  Perhaps one of 
you can tell from the UMAX UTA-11 parts list located at:
