This option provides control over the condition of the device at power-up or reset. Figure 1-2 shows a U3-HV with the factory default power-up configuration, which means AIN0-AIN3 set to analog input, FIO4 to CIO3 set to digital input, analog outputs set to minimum voltage (near 0), and timers/counters/watchdog disabled.

Any configuration done on this screen is not written to nonvolatile memory. These settings just affect the current condition of the device, not the reset/power-up condition.
When the test panel first loads it sets everything to factory default, so previous settings (or reset/power-up settings) will not be shown.
LJCP Settings
Selecting Options→Settings from the main LJControlPanel menu brings up the window shown in Figure 1-4. This window allows some features to of the LJControlPanel application to be customized.
