SCSI for Scanner

[ahayes1ic]

I have recently bought an AHA-2940 S6 PCI SCSI card in the hope of replacing the aging DTC 3181x/3151x SCSI II ISA card that is no longer supported in the newer operating systems. The DTC card came with my ARTEC Viewstation AT12 scanner.

Will the AHA card run a scanner (this scanner?) and if so is it only a matter of installing the drivers for this SCSI card to get the scanner to operate? (I have been fiddling with this problem for quite a few days, I hope the new card is compatible)

Cheers

Welcome ... :)

Scsi 2940 is supported 'natively' by most MS operating systems ... so when you fit the card it should be 'found' by windoze without any problems ...

The only issue jumping out at me ... is will it connect? I'm having a devil of a job locating the specs for the original controller card ... I just want to know as will you, that it has the right connectors for the job !

As far as I remember your 'old' card has a 25pin external connector Like this one (http://www.umax.co.uk/support/technotes/f096B.htm) ... a 2940 being scsi 'wide' would have 50 pins ... so no fit !! Which is no good.

The 'new' card is capable ... but not if you can't connect it up ! So I think you will also need a converter like one of these (http://www.programmersparadise.com.au/prod_avail.asp?SC=1)

BUT that all depends if there is a pin mismatch !

You have all three, so without even putting anything inside the box can you confirm the cable from the scanner can actually plug to your 'new' card ... ?

Notwithstanding the cabling issue (I have seen 50 pin to 25 pin cables, but they are hard to find), you may also need a driver for the scanner compatible with the new operating system. Scanner must be turned on when the system boots or it will not be detected. Chances are it is a TWAIN driver, which means the scanner will have to be installed as an "unsupported device". This is different from an "unknown device" and is a choice you can select manually in device manager.

Artec driver download page:
http://64.70.234.121/pages/SCSI_scanner_drivers.htm

"If your original SCSI card is DTC ISA interface, it doesn't support Window 2000 operating system. You must purchase a new standard SCSI II card which supports Window 2000. Please be aware that our scanners are not compatible with Ultra Wide SCSI cards. "

I am using Win XP Pro and the 2940 SCSI driver installed and when I boot up before windows loads I get a SCSI bios detection message but nothing about the scanner being detected at that point. I have been in the SCSI setup and it has the scanner detected at device 5. I have purchased the correct connectors (I hope) - 50 pin slim (SCSI card) to 50 pin centronix (scanner). Will these pins match up then?

Are there any other drivers that I will need? I have been to most sites around that carry driver for this scanner and none of them seem to work. Am I supposed to install some scanning software to interface with the scanner?

I have just tried to install the drivers suggested and changed the compatibility of the setup file as suggested and the install completed succesfully. I then run the installed shortcut and receive this message - "Unable to open driver failure or no scanner" and the program ends??

Does XP detect the scanner in device manager? If so, what is it listed as and does it have a yellow exclamation point next to it? If so you will need to manually install the driver.

Manually extract the driver files using winzip. Go into device manager and select update driver, have disk. Point it to the a2000.inf file which should have been extracted to the \w2000 directory.

It has recognised new hardware and attempted to install scanner software for all device IDs. After finshing this I still cannot get it to scan. Now I cant even get it to detect that there is a scanner connected. Scan for new hardware shows no new hardware and the device is not listed in the device manager.

[hudsonsmith]

If it has recognized new hardware and attempted to install the software, it should be listed somewhere in device manager. SCSI scanners will often not be listed under the scanner/camera heading. Expand the other headings.

BTW, I assume the SCSI card is appearing in device manager?

Does the scanner require termination?

Can you try changing the scanner's SCSI ID?

Try downloading and installing the newest ASPI32.EXE for Windows 2000/XP off Adaptec's website as well.
