Firmware updating of the Elpro devices is possible using the specific utility UPLOADER.

This software should be downloaded and installed on a PC in a Windows environment.

To perform the updating of the firmware it is necessary to connect the device to the PC serial line and therefore to perform the action (typical for every device) to put the device in UPGRADE MODE.

Then load the .hex file of the new firmware version and start uploading to the device.

At the conclusion of the updating it is necessary to turn OFF and ON again the device.
