external in and out triggers on pxi 6541

[bjasper]

I need to use both trigger-in and trigger-out events.  It appears there is only one front panel port, i.e. SMB PFI<0>.  If I use that port for the trigger-in, what options are there to get a trigger-out signal out of the box (not pxi bus)?

The PXI 6541 actually has four PFI lines which can be used for importing and exporting triggers - though as you've determined, only PFI 0 has a direct front panel connection.  The others (PFI 1-3) are accessible through the Digital Data & Control port, and thus can be easily accessed when using either the CB-2162 or SMB-2163 connector block (or any similar breakout for the DDC port):

Hope this helps!
