Note Selecting any non-disabled routing automatically reserves the line in all trigger
buses being routed to. If you are using NI-DAQmx, it will reserve and route trigger lines
for you, so you won’t have to route trigger lines manually.
Complete the following steps to configure trigger routings in MAX.
1. In the Configuration tree, select the chassis in which you want to route
trigger lines.
2. In the right-hand pane, select the Trigger Routing tab near the bottom.
3. For each trigger line, select Route Right, Route Outward From
Middle, or Route Left to route triggers on that line in the described
direction, or select Disabled for the default behavior with no manual
routing.
4. Click the Apply button.
Using System Configuration and Initialization Files
The PXI specification allows many combinations of PXI chassis and
system modules. To assist system integrators, the manufacturers of PXI
chassis and system modules must document the capabilities of their
products. The minimum documentation requirements are contained
in .ini files, which consist of ASCII text. System integrators,
configuration utilities, and device drivers can use these .ini files.
The capability documentation for the PXI-1056 chassis is contained in the
chassis.ini file on the software media that comes with the chassis. The
information in this file is combined with information about the system
controller to create a single system initialization file called pxisys.ini
(PXI System Initialization). The system controller manufacturer either
provides a pxisys.ini file for the particular chassis model that contains
the system controller or provides a utility that can read an arbitrary
chassis.ini file and generate the corresponding pxisys.ini file.
System controllers from National Instruments use the Measurement &
Automation Explorer (MAX) to generate the pxisys.ini file from the
chassis.ini file.
Device drivers and other utility software read the pxisys.ini file to
obtain system information. Device drivers should have no need to directly
read the chassis.ini file. For detailed information regarding
initialization files, refer to the PXI specification at www.pxisa.org.
