The RTG Configuration Utility is a Windows desktop application for creating, editing, and validating RTG configuration INI files. It is written for end users who set up and maintain the configuration that tells the RTG software which hardware is installed and how it is connected.

Configuration Utility Functions

The RTG Configuration Utility helps you build and maintain the INI files that configure the RTG. You can use the Configuration Utility to perform the following tasks:
  • Create new configuration files
  • Edit existing files through a guided, form-based interface without manual text editing
  • Validate files automatically as you work, with clear visual feedback
  • Discover hardware installed in your PXI system and add it to a configuration with a single command
  • Set the default configuration the RTG software uses
The Configuration Utility presents the configuration as a tree of sections and fields, validates your entries, and only allows you to save files that are valid.

Configuration Files

A configuration file is a standard INI text file made up of sections and keys within those sections. RTG configuration files describe the following characteristics:
  • General server and API settings
  • Driver settings
  • One section per installed instrument (VST) or coprocessor
  • Attenuator assignments associated with instruments
You do not need to memorize the section or key names; the Configuration Utility presents them for you and validates the values you enter.

Default File Location

The RTG software reads one default configuration file, which is located at %PUBLIC%\Documents\National Instruments\RTG\RTG Configuration Support.ini. You can keep several configuration files and tell the software which one to use without moving or renaming files. When you mark a file as the default, the Configuration Utility writes a pointer (the INIPath key) into the default file so the software loads your chosen file instead.
