PXI Trigger Bus Routing
Some National Instruments chassis, such as the PXIe-1088, have the capability to route
triggers from one bus to others within the same chassis using the Trigger Routing tab in
MAX.
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 Away from Bus 1 or Away from Bus 2 to route triggers on
that line in the described direction, or select Dynamic for the default behavior with no
manual routing.
4. Click the Save button.
Fan Configuration in MAX
You can configure fan behavior using software settings in MAX
The PXIe-1088 supports both Auto and High fan modes for both the 38 W and 58 W cooling
profiles. Refer to the Fan Mode section for more information about these modes.
You may also select a Manual fan mode. In this mode, you may manually set the fan speeds to
achieve the desired performance.
Note You may not set the fan speeds or power settings lower than the minimum
level required to maintain required cooling levels.
Complete the following steps to change the fan settings in MAX .
1. In the Configuration tree, click on the PXI chassis you want to configure.
2. In the right-hand pane, click on the Settings tab.
3. In the Fans group, select the desired Mode and Cooling Profile using the drop-down
menus.
4. Click the Save button. Shortly after clicking the Save button, you should see the fan
speeds change.
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 PXIe-1088 chassis is contained in the chassis.ini
file on the software media that comes with the chassis. The information in this file is combined
