Which analog input channels are differential pairs on my M-Series Card?

Can someone direct me to documentation where the analog input differential pairs are defined for the PCI-6289 card?  I'm also looking to find which channel of each pair is the high side, and which is the low side.
 
Thanks,
JLW

It's in chapter 3 (connector information) of the user manual. In case you lost it, it can be downloaded from http://digital.ni.com/manuals.nsf/websearch/C6E6341BE4DCF3548625713000582517.
