Click the PXI System controller, and the chassis (or multiple chassis,
in a multi-chassis configuration) will be listed below it. Identify each
chassis by right-clicking its entry and then selecting the appropriate
chassis model through the Identify As submenu. Further expanding
the PXI System branch will show all of the devices in the system that
can be recognized by NI-VISA. After your controller and all of your
chassis have been identified, the required
complete.

Apply the chassis number labels (shown in Figure 2-7) included with
your kit to each chassis in your PXI system, and write in the chassis
number accordingly in the white space.
Each chassis has one or more trigger buses, each with eight lines numbered
0 through 7 that can be reserved and routed statically or dynamically. Static
reservation "pre-allocates" a trigger line to prevent its configuration by a
user program. Dynamic reservation/routing/deallocation is performed
on the fly within a user program based upon National Instruments APIs
such as NI-DAQmx. Static reservation of trigger lines can be implemented
by the user in MAX through the Triggers tab. Reserved trigger lines will
not be used by PXI modules dynamically configured by programs such as
NI-DAQmx. This prevents the instruments from double-driving the trigger
lines, possibly damaging devices in the chassis.
Complete the following steps to reserve these trigger lines in MAX.
1.
In the Configuration tree, click the PXI chassis branch you want to
configure.
2.
Click the Triggers tab at the bottom of the right-hand pane.
3.
Select which trigger lines you want to statically reserve.

Click the Apply button.
