Mounting the NI-793xR

You can mount the NI-793xR in a variety of configurations. The following table lists the
ecommended mounting methods.

The following sections contain instructions for the mounting methods. Before using any of these
mounting methods, record the serial number from the back of the device. You will be unable to
read the serial number from the back of the device after you have mounted it.

Caution

You must provide physical support for any FlexRIO adapter modules

during the mounting process.
