PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with
adjacent peripheral slots to the left and right.
The backplane routes PXI Local Bus 6 between all slots. The left local bus 6 from slot 1 is not
routed anywhere, and the right local bus 6 from slot 9 is not routed anywhere.
