Windows 7: Adaptec 29160 // 2940 // SCSI connection...

Adaptec 29160 // 2940 // SCSI connection...

I have an Adaptec 2940AU card from my old 32bit system. I used it to drive a Nikon scanner with a 50pin-50pin connection cable. Now, that card is not supported under W7/64 for my new PC.

I have also an Adaptec 29320LPE: External: 68pin VHDCI, Internal 68pin Ultra320 (PCI-e)

I have an Adaptec 29160: External 68-pin LVD, plus internal { 68pin LVD; 68pin UW-SCSI; 50pin Ultra SCSI } (PCI)

I have googled around until I have a headache. How to use what I have got to get the Nikon scanner working on my W7/64. I have PCI and PCI-e slots available. I have not found a 68-50 adaptor cable, which seems basically what I need to use either of these. Then there is also a question about this requirement in the Nikon manual: DOS ASPI-compatible SCSI board with WINASPI.DLL. Are these two faster boards DOS ASPI-compatible? As I understand it, WinAspi is a DLL which must serve Aspi calls on the SCSI device? The faster boards have 64-bit drivers, so....?

I am not a computer geek who has all this stuff at their fingertips, but I am sure there will be such a person on your site.

Some help, need more...

OK, those are useful, but raise a new question: how do I tell the difference between a 50-way Centronics and a 50-way half pitch D connector, I have looked around and even found Lindy Connections but the pictures are too small to figure the difference. Also, is there some sort of 'termination' problem to sort out when going from the 68 LVD, whatever that is, to the 50way? Sorry to be so thick, but....

Also, I need to know about this ASPI question, if possible.

Further to my last... I have managed to find a scrap, a miserable scrap, from the Nikon site. The panel-mounted receptacle for the SCSI cable connection is described as
Female half-pitch 50-pin

SCSI connector
which suggests to me that I need a 68-way xxxx to 50-way half-pitch D male Thumb clip type as listed in your ref. link.

This is a photo of my old Nikon SCSI cable. It looks more D connecter than Centronics, from my distant past, but why 'half pitch'?

This gives a guide on the connectors associated with SCSI. SCSI Explained Ultra LVD Cable Connector Guide - Advanced Horizons

The Centronics connectors are referenced as CN50-M and CN50-F. These were the older external connectors, and they have been superceded by smaller versions, usually termed as half pitch. These connectors are termed HD50-M and HD50-F.

From what you have said, you require a HD68-M to HD50-M cable. I've located the following:

Hope this helps someone looking for Adaptec 2940 or 2906 or similar driver to work for 64-bit Windows 7.

I was able to get the 2940 driver to work in 64 bit W7, actually it is working for my Adaptec 2906.
Google fu was working for me today. Feel free to PM me for help if you like.

I copied the following into a file called djsvs.inf, then I updated the driver by first looking for an Adaptec Storage Controller, then browsing to the djsvs.inf file
