Section 8. CR200(X) Configuration double clicking on a value cell with the mouse. The grid will not allow readonly settings to be edited. The bottom of the Settings Editor displays help for the setting that has focus on the top of the screen. Once a setting is changed, click Apply or Cancel. These buttons will only become enabled after a setting has been changed. If the device accepts the settings, a configuration summary dialogue is shown (FIGURE. Summary of CR200(X) Configuration p. 63) that gives the user a chance to save and print the settings for the device. Figure 41: Summary of CR200(X) Configuration Clicking the Factory Defaults button on the Settings Editor will send a command to the device to revert to its factory default settings. The reverted values will not take effect until the final changes have been applied. This button will remain disabled if the device does not support the DevConfig protocol messages. Clicking Save on the summary screen will save the configuration to an XML file. This file can be used to load a saved configuration back into a device by clicking Read File and Apply. 63
