Issue Details

I have a second network card in my Real-Time PXI chassis, such as a PXI-8231, and MAX won’t detect it under Devices and Interfaces.  How do I get this card to show up?

Solution

The PXI(e)-823x series cards appear under the Network Settings tab instead of the Devices and Interfaces section of MAX. The Primary adapter is the adapter on the controller itself, marked as eth0, while the additional Ethernet ports will appear as the secondary adapters (eth1, eth2...).
 

Missing Ethernet adapters is due to the adapter using a different chipset.  By default, most drivers are not installed.  You can install the other drivers by using the Add/Remove Software dialog.
 

 
Note: The device's chipset is listed on the device's project page or manual. For example, the PXI-8231 product page states: "The NI PXI-8231 is a high-performance Gigabit Ethernet module for PXI systems based on the Intel 82541PI Gigabit Ethernet controller".  For this device, installing the Intel 8254x Ethernet Driver should cause the additional ports to appear under Network Settings.  The ports are enumerated automatically, although they may not match the order on your Ethernet adapter module.  If you run into communication errors after setting up your port, try swapping the cable to the other Ethernet port since the enumeration may not match the numbering on the module.
