General Controls

Reset USB Port:

Begins a new USB session. Click this button if a status error message occurs.

Readback Enabled/Disabled:

Enable or disables the DAC register reads. When Readback is disabled, the software enters simulation
mode. If communicating with the DAC is a problem, the software enters into simulation mode
automatically.

Save Settings:

Saves the DAC and CDCM7005 register configurations to a text file for future use.

Load Settings:

Loads a DAC and CDCM7005 register configuration from a text file and updates the GUI.
