Figure 3-1: PXI Local Bus and Star Trigger Routing
Local Bus
The PXI backplane local bus of the 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
bus bandwidth. In accordance with the PXI specification, local bus
connections are between all slots except slots 1 and 2.
Trigger Bus
The PXIS-2680P implements a dedicated PXI trigger bus with 8
lines. Users can use these trigger lines to synchronize the opera-
tion of several different PXI peripheral modules, or use one mod-
ule to control carefully timed sequences of operations performed
on other modules in the system. Modules can pass triggers to one
another through trigger bus, allowing precisely timed responses to
