Default Setup
On FlexDCA, click Setup > Default Setup to return the FlexDCA to a known start-up state. To set FlexDCA to its factory preset condition, click Setup > Factory Preset. You may find it helpful to use the default settings when initially setting up FlexDCA to view signals or to troubleshoot unexpected instrument behavior. The default settings are listed in the following table.
On a DCA-X, press Default Setup to return the instrument to its factory default conditions. The instrument saves all customized settings in a file, which you can reload.
When a DCA-X is remotely controlled, the Local button and ON/Standby switch are the only active front-panel controls. Press Local to return control of the instrument to the front panel. On FlexDCA, click Tools > Virtual Front Panel and click Local.
Because the settings of DCA-M extended modules are configured within FlexDCA, a default setup also returns DCA-M products to their default settings.
