The local bus of PXI backplane cBX-3008L is a daisy-chained bus that
connects each peripheral slot with its adjacent peripheral slots at the left
and right. Each local bus is 13 lines wide and can pass analog or digital
signals between modules, or provide a high-speed side-band
communication path that does not affect the PXI bandwidth.
In accordance with the PXI specification, the local bus connections
between all slots except slots 1 and 2.
