PXI Trigger Bus Routing
Some National Instruments chassis, such as the PXI-1075 and the
PXI-1044/1045, have the capability to route triggers from one bus to others
within the same chassis using the
Trigger Routing
tab in MAX, as shown
in Figure 2-6.
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.
