PXI Express System Controller Slot
The System Controller slot is Slot 1 of the chassis as defined
by the PXI specification. The PXES-2780 chassis can accom-
modate a PXI Express system controller that occupies width up
to 4 slots. As defined in the PXI specification, three controller
expansion slots allow the controller to expand to the left to pre-
vent the controller from using up peripheral slots.
PXI Express System Timing Slot
The System Timing (ST) slot is Slot 10, providing one dedi-
cated single-ended star trigger and 3 pairs of differential star
trigger lines to each peripheral slot. Routing of single ended
star trigger signals (PXI_STAR) and differential star trigger sig-
nals (PXIe_DSTAR) are as follows.
