For more information on scanlist configuration, scan mode setup, start, and
stop functions of the auto-scanning process, please refer to the software
programming users’ guide.
4.4 Trigger Bus
PXI specification defines eight bused-lines across slots in a segment. Users
can route various trigger signal to synchronize multiple PXI instruments, and/or
simplify field wiring across multiple ADLINK Switch Modules.
On ADLINK Switch Modules, the trigger bus driver is disconnected from PXI
trigger bus before users’ configuration.
