Please log in for more thread options things. All I need this for is to run a slide scanner I have. I don't have any other devices I need to run off it. Now, there is a ribbon cable with it. Question here is .... does such a cable have to be used or is that just if you want to have a chain of devices ? There is also a bit for POWER from the PC to go into. Is this actually needed ? I have seen a diagram of the board and this power input is labelled as LED Connector (situated just above an LED labelled as Host Adapter LED. If all I want the SCSI card for is to eneble me to connect my slide scanner to the PC can I just plug the card into PCI slot and sort out the drivers ? Does the card actually need power input ?? Cheers for any info, Woody | ||||||||||||||||||||||

Please log in for more thread options Ahhh ... hold on a min. I have just looked at the card and it seems it is not a 2930 but a 2940U2W. Plus the power input is not on the card but on some sort of PCB which is on the ribbon cable.... which I hope I don't need. Woody (again) | ||||||||||||||||||||||

Bus terminations. Some devices have a built-in terminator, and some require the user to plug an external terminator, if the device is the last one on the bus. You need to read up on termination. Termination is important to signal quality. http://en.wikipedia.org/wiki/Parallel_SCSI http://www.scsita.org/aboutscsi/termTutorial.html If you'd mentioned the slide scanner model, it might have been easier to dig up some more info.

Good input as usual Paul. I take it the scanner is external (heh) so it's fairly safe to assume that it's internally terminated (or has that option). Probably has a device on the back to set ID number (won't matter if it's the only SCSI device attached to the card) and maybe termination. Or it'll have one of those terminator blocks fitted to the second cable interface, hopefully. (If it has one). So, Woody, just slot the card in, plug in your scanner and try it out. You won't break anything and, chances are, it'll work just fine. There's even a good chance that Windows will find a driver for it. (Although I'd personally use one downloaded from Adaptec.) Luck, -- Shaun. | ||||||||||||||||||||||

Please log in for more thread options The scanner is a Nikon Coolscan III (LS-30). Prety sure it does have built
in terminator. I haven't tried it with the scanner on yet as scanner is in my house and I'm building the machine at work. Windows has picked up the SCSI card OK but I have also been on Adaptec page and got the slightly updated ones. I'm stuck with Windows 2000. Was going to put XP on but I have read of many users of this scanner having issues with XP sp2, and Nikon don't seem to support it. I think I'll build an XP model too and take a ghost image of that and my w2k anyway so if it doesn't work on XP I can revert quickly. Cheers for replies Woody | ||||||||||||||||||||||
