How do I figure out the software to hardware bit mapping when using an SCB-68?

I'm using DAQmx (C++) to drive my PCIe-6251.  To date, I've been successfully using 8 digital output lines, but now I need to drive 16 digital output lines.  My PCIe-6251 had been connected to a BNC-2120, but it only supports 8 disital output lines so I've replaced it with a SCB-68.  I have yet to change my software -- which is good because this is a hardware question. 

 

On the BNC-2120, my 8-bits of output showed up on terminals P0.0 -> P0.7.  On the SCB-68, there are no terminals labeled P0.0 -> P0.7.  Which terminals have my 8-bits of output?

The SCB-68 serves as a breakout connection to all of the pins of your PCIe-6251, thus the pin mapping is the same for your card.  Check out page 14 of the NI-625x manual for your device pinout.
