The KPA1500 preserves configuration data, antenna tuner (ATU) settings, and a fault log in non-volatile memory (EEPROM).
Opens an Edit Configuration dialog where you may view or change the tuner's configuration.
Save Configuration writes all KPA1500 EEPROM data into a file. This file may be requested by Elecraft Customer support for problem diagnosis, as it contains the complete amplifier configuration, fault log, and all ATU settings. Firmware (the microcontroller program instructions) is not saved in the configuration file.
Click to show a "Save As" dialog where you may provide the name of a new file that will receive configuration data. A suggested file name is generated from the KPA1500 serial number and the date and time, but you may overtype this with any valid file name. Click "Save" to begin saving configuration and tuner memory data.
About 100 seconds are required to save the configuration at a serial speed of 230,400 bits/second.
The KPA1500 Utility creates a folder intended for configuration files, located under the current user's Application Data folder. You can locate the current user's Application Data folder by entering "cd %APPDATA%" from a Windows command prompt.
You may use this folder, or use the Save As dialog to navigate to a different folder for saving configuration files.
Click to show a File Open dialog. Select an appropriate configuration file and click "Open". Your KPA1500's configuration data and tuner settings will be restored from the selected file.
The fault log is not modified by configuration restore.
Do not modify the configuration file between Save and Restore, or Restore may fail.
Click to show the KPA1500 fault table. The table is quite large, and it takes several tens of seconds to read completely. The time to read the fault table is greatly affected by Host serial port speed.
Most fault log entries contain:
The fault codes are:
Click to show an Antenna Tuner Memory Erase dialog.
Select a single band (or All bands) and then click one or more of the Antenna Buttons.
Click to show a Reset to Factory Default dialog
Click "OK" to reset KPA1500 configuration to the factory default values. You should consider saving the existing configuration first.
This reset does not change Antenna tuner settings. Antenna tuner settings may be erased with Erase Antenna Tuner Memories.
Your KPA1500 includes a clock/calender device to timestamp fault log entries.
Click OK or Apply to set your KPA1500's date and time from your Personal Computer's date and time. OK closes the dialog, Apply does not.
The format is YY-MM-DD HH:MM:SS.
The factory normally initializes the clock to the current UTC date and time.
