6. Once the unit controller has rebooted and the CORE Service app has reconnected, it is recommended to repeat steps 1 and 2 to verify the firmware has been updated.

NOTE : Firmware information is also listed on the unit controller’s seven segment display during boot-up.
The firmware is listed in the following order:

• Major
• Minor

NOTE : Firmware updates do not alter the unit controller configuration settings. All settings will be retained after the firmware has been updated.

Saving and Loading System Profile

Saving System Profile

This functionality saves a “profile” on the controller. What that means is that It sets a restore point on the controller that the controller can be returned to in case the controller is configure incorrectly, loses configuration, etc. This profile is created from the parameters already saved on the controller.

Because of that, there is no need to source a file from the USB, mobile app, etc. Instead, the user just clicks save, and the controller saves the appropriate parameters internally.

1. Insert a compatible USB storage device
2. On the CORE service app, go to RTU MENU > REPORT and select SYSTEM PROFILE.
3. Type a unique name for the profile in the PROFILE NAME field
4. Choose SAVE under either MOBILE or USB depending on the device you would like to use.
5. If MOBILE is selected, your device will prompt you to choose a location to save too.

NOTE : If the CORE Service App indicates the unit controller was unable to read the USB storage device, remove and reinsert USB storage device and attempt to save the profile again.

Loading System Profile

1. Insert the USB storage device that contains the current saved System profile, or continue if you have a system profile saved on your mobile device.

2. Go to SERVICE > REPORT. Choose LOAD under mobile or USB, depending on where your system profile is saved.
   NOTE : The CORE Service app may indicate either the unit controller was unable to read the USB storage device or it is missing. Remove and reinsert USB storage device and attempt to load the System Profile again. If the issue continues, all data will have to be entered manually.

3. Select the desired System Profile by using the CORE service app. If loading a system profile from USB, select NEXT to continue. If the process was completed successfully, the app will indicate “System Profile Loaded”
