NI PXIe-1085 Series User Manual

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 Express specification allows many combinations of PXI Express chassis and system

modules. To assist system integrators, the manufacturers of PXI Express 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 NI PXIe-1085 Series 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 NI provide the

pxisys.ini file for the NI PXIe-1085 Series chassis, so you should not need to use the

chassis.ini file. Refer to the documentation provided with the system controller or

to ni.com/support for more information on pxisys.ini and chassis.ini files.

Device drivers and other utility software read the pxisys.ini file to obtain system

information. The device drivers should have no need to directly read the

chassis.ini file. For

detailed information regarding initialization files, refer to the PXI Express specification at
