always load to an adapting state. (If you want to clear a filter and leave it clearedfor a period of time, you can first freeze adaptation and then clear the filter.)To store a configuration, click the “File” menu and then “Save Config As…”.5.8 Recalling ConfigurationsWith the MicroDAC 5 software you can recall configurations that you havepreviously saved to files. Upon recalling a config file, the software screen willupdate to those settings and also send those settings down to the hardware if aMicroDAC 5 unit is connected.To restore a configuration, click the “File” menu and then “Open Config…”. Thiswill bring up a standard Windows browse dialog where you can select the configfile you want to load. Click “Open” and the configuration will be loaded.Important Note: Recalling a configuration is not the same as “programming”settings into the unit! Recalling a configuration file will change the currentoperating behavior of the unit (if one is connected), but it will not change thesettings stored in nonvolatile memory on the unit. Think of recalling configurationfiles as a shortcut to manually changing all your software settings. If you want toprogram these settings into the nonvolatile memory in the hardware (so thatthose settings will be used after the unit is disconnected from the PC), you stillneed to choose “Program MicroDAC 5” from the File menu. See section 5.10 formore information about programming the MicroDAC 5 hardware.5.9 Connecting to the MicroDAC 5The hardware is connected to the PC via a USB cable. To connect theMicroDAC 5, follow these steps:1. Connect the USB cable that is provided to the MicroDAC 5 hardware andthe PC.2. Power on the MicroDAC 5 unit.3. The PC should recognize the MicroDAC 5 within a few seconds.4. Start the MicroDAC 5 Configuration Utility software.5. The software will automatically detect and connect to the MicroDAC 5.If the Controller software is already running, you can still connect a MicroDAC 5to the PC by selecting “Connect” from the File menu.Upon connect, is it is likely that the current software settings will be different fromthe programmed settings in the hardware. When these settings do not match,the user is prompted to load the current hardware configuration into the software.If the user selects “Yes,” then the software will read the programmed settingsfrom the MicroDAC 5 unit. (This is the easiest way to determine what settingsPage 20
are stored in nonvolatile memory on an unknown unit.) If “No” is selected, thenthe most recent software configuration will be “pushed” down to the hardware,and the hardware will begin running at the settings that were in the software priorto connection. Note that “pushing” software settings will not overwrite thenonvolatile memory – if you were to disconnect, the unit would return to its storedsettings unless you explicitly re-program its nonvolatile memory.You can only have one MicroDAC 5 powered up and connected to the PC at anygiven time.5.10 Programming the MicroDAC 5Once the MicroDAC 5 is connected to the software, you can program it at anytime by clicking on the “File” menu and then selecting “Program MicroDAC 5”.By programming the MicroDAC 5, you are taking the current settings in thesoftware and storing them in the nonvolatile memory of the hardware. Thisenables the MicroDAC 5 to be disconnected from the PC, turned off, anddeployed. Now, when the unit powers on, it will reload the settings that youprogrammed into its memory.If you attempt to disconnect from the hardware without programming the latestsettings, the software will display a prompt asking if you wish to do so. This is tohelp prevent the user from accidentally neglecting to program the unit upondisconnect. If you choose to program, the latest software settings will beprogrammed and the unit will continue to run at these settings after it isdisconnected. If you choose not to program, the unit will revert to itsprogrammed settings upon disconnect.To protect against inadvertent changes in the programmed settings, the PCalways programs the nonvolatile memory into the “locked” state. In order tochange the channel mode or bandwidth in a tactical situation after PCprogramming, the user would have to unlock the device (see section 3.1.5).Once a unit is programmed, there are only two ways to change its nonvolatilememory state:1. Reconnect to the PC and reprogram the unit, or2. Unlock the unit and use the front panel filter controls to change thebehavior.Important Note: Once the unit is unlocked, any changes made using the frontpanel filter controls are preserved in the nonvolatile memory. This behaviorallows the unit to maintain its current operational state in the event of anunexpected power loss.Page 21
