PC8 Device Agent is an application that allows you to configure the PowerControl 8 device. The program will display a connection icon in the status bar, indicating that communication with the PC8 is established. Also, it will load and display the current settings of your PC8 automatically. The current settings can always be re-loaded by clicking Load from the PC8 button in the status bar.
