I have a Mac Pro 2.1 computer, running OS X 10.6.8, 4GB RAM. I would like some tips on how to successfully connect up some scanners that I have. I'm not having much luck. I have a UL5D LP card with the latest driver and flash bundle. I only want to connect each scanner individually, not as a Daisy chain.
I have 4 SCSI scanners as follows :
UMAX PowreLook II
UMAX PowreLook III
Heidelberg Linoscan 1400
Agfa Arcus 1200
The only one I can get to be recognised is the Arcus 1200.
Each of these have the same 2 SCSI connectors. A 50 pin Centronics and a DB 25. I am connecting using a VHDCI to 50 pin Centronics cable with a passive DB 25 terminator.
I am using the same cable and terminator for all scanners, yet only the Arcus 1200 is recognised. I have tried connecting and reconnecting each scanner a few times with out luck. No matter what i do, I can't get the other three to be recognised. Whilst i have not actually tested them on another computer, there is no doubt in my mind that the other scanners are fine. There is nothing wrong with them. They are not damaged in any way. They should be working just like the Arcus 1200.
Any help with this would be most appreciated.
