External Trigger on NI_6025e

Hi again,
	I am having real problems getting my card to do anything with an 
external trigger.
	To test triggering all I want to do is start a scan from an 
external trigger.
	The NI_6025e uses PFI0 and PFI1 for trigger inputs.  info.c 
reports these to be digital I/O points.  Do I have to do any extra 
configuration to use these as external trigger inputs?     

I am assuming that cmd->start_src = TRIG_EXT
                   cmd->start_arg = 0
would use PFI0 as the trigger input to start data acquisition.  
I think that PFI0 translates to subdevice 7 channel 0.		

Am I completely off track?

Any guidance would be greatly appreciated.
 regards
Dylan
