Local Bus
The PXI backplane local bus is a daisy-chained bus that connects
each peripheral slot with its adjacent (left/right) peripheral slots.
Each local bus has 13 lines and can transmit analog or digital sig-
nals between modules. It also provides a high-speed side-band
communication path that does not affect the PXI bandwidth.
Based on PXI specifications, the local bus connects all adjacent
slots except slots 1 and 2.
