The SS20 has an internal bootloader that allows users to upgrade firmware in the field. The tools menu is used to load firmware into the attached device.
All user configuration settings will be lost when firmware upgrade is performed. It is recommended to save the current configuration by clicking Device > Config > Read and then File > Save As before running the Firmware Load Utility.
To upgrade the firmware follow this procedure:
Verify the USB Mode switch on the device is set to
GUI.
Click Tools > Firmware Load from the menu.
A popup will appear. The current firmware version matching the version of
GUI software running is automatically opened by default in the File box. If a different version is desired, browse to the firmware file location using the folder icon next to the file box.
Select the Com Port associated with the USB’s VCP connection and click OK. A warning will appear as a reminder that the user configuration will be erased.
Click OK. The current firmware will then be erased and the new firmware will begin loading. The status bar will display the status of the firmware load with a % complete and the out Tx and Rx LEDs will flash red until loading is complete.
Once complete, the device will boot back up and you can write the user configuration back into the device.
If an SS20 unit’s status LED is continuously flashing red it means that the installed firmware is either missing, invalid, or corrupt. This may happen if the firmware loading process is interrupted in mid-transfer. In this situation, the firmware may be re-loaded using the above procedure.
