1. PXI Express System Controller Slot
2. PXI Peripheral Slot
3. PXI Express Hybrid Peripheral Slot
4. PXI Express System Timing Slot
5. PXI Express Peripheral Slot
PXI Express devices can be placed only in PXI Express slots and PXIe Express Hybrid
slots. Refer to the chassis documentation for details.
3. Remove the filler panel of an unused module slot.
4. Touch any metal part of the chassis to discharge any static electricity. Place the module
edges into the module guides at the top and bottom of the chassis, and slide the module
into the chassis until the module is fully inserted.
5. Secure the device front panel to the chassis front panel mounting rail using the front panel
mounting screws.
6. Plug in and power on the chassis.
Configuring the PXIe-7902 in MAX
Use Measurement & Automation Explorer (MAX) to configure your National Instruments
hardware. MAX informs other programs about which devices reside in the system and how
they are configured. MAX is automatically installed with NI LabVIEW Instrument Design
Libraries for High Speed Serial Instruments.
1. Launch MAX by navigating to Start»All Programs»National Instruments»NI MAX or
by clicking the NI MAX desktop icon.
PXIe-7902 Getting Started Guide | © National Instruments | 5
2. In the Configuration pane, expand Devices and Interfaces to see the list of installed
devices. Installed devices appear under the name of their associated chassis.
3. Expand your Chassis tree item. MAX lists all devices installed in the chassis. Your
default device names may vary.
Note If you do not see your module listed, press <F5> to refresh the list of
installed modules. If the module is still not listed, power off the system, ensure
the module is correctly installed, and restart.
4. Record the device identifier MAX assigns to the hardware. Use this identifier when
programming the PXIe-7902.
5. The MAX self-test performs a basic verification of hardware resources. To self-test a
module in MAX, right click the module and select Self-Test.
If any module fails the self-test, refer to the Troubleshooting section of this document.
Accessing Sample Projects
