PXI Express Configuration Information

For PXI Express devices, NI-VISA must know the correct register operation sequence to obtain the slot the device is currently plugged into. After you insert a device into a PXI Express chassis and power on the device, the device reads the slot number from pins on the chassis and stores the number in a memory register. To configure the device and chassis automatically, this information must be read from the device memory. Use the NI-VISA Driver Wizard to define how to read this information.

The register operation sequence includes register reads, reads masked with a set value, and reads shifted a set number of times. Enter individual register operations into the sequence exactly the same way as interrupt detection, removal, and disarm sequences.
