Can I export the I/O configuration of a Unity Pro project?

Yes.This function can be accessed by right clicking on the Configuration folder in the project browser. It allows you to export the complete configuration of the inputs/outputs of an existing project, which can then be imported into a new project. The following information are exported:
Bus parameters, rack(s), modules, and channel parameters.
When you export the input/output configuration a .XHW file is created. This file is in XML format.
