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 adjacent PXI slots. The left Local Bus 6 from
slot 1 is not routed anywhere. The right Local Bus 6 from slot 8 is also not routed anywhere.
Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V.
Initialization software uses the configuration information specific to each adjacent peripheral
module to evaluate local bus compatibility.
