I have a 2944UW. I have to use that for my DLT drives because they are 
low-voltage-differential. I believe that the 2940U or W or UW or U2W (never 
seen one of those) were also made in a 2944 version for LVD devices.

I have 2944 in the next slot over from a 2940UW because my other drives are 
conventional interface and I use both on the same box at various times.
