LightHouse Charts file encryption
LightHouse Charts file encryption

LightHouse cartography is encrypted for use with the microSD memory card onto which it was first downloaded from the LightHouse Charts Store. As such, a properly populated microSD memory card containing LightHouse Charts may be ejected from the memory card reader of an a/c/e/eS/gS-Series MFD and then inserted into the memory card reader of another a/c/e/eS/gS-Series MFD operating with the latest a/c/e/eS/gS-Series MFD software to permit the cartography to be viewed on the other MFD. However, copying the contents of a properly populated microSD memory card containing LightHouse Charts to another microSD memory card will result in a mismatch of the Lighthouse_ID.txt file with the second microSD memory card, prohibiting use of the copied LightHouse Charts with the second microSD memory card.

When a microSD memory card is inserted into the memory card reader of a fully booted a/c/e/eS/gS-Series MFD operating with the latest a/c/e/eS/gS-Series MFD software, the MFD will save a Lighthouse_ID.txt file onto the microSD memory card. The Lighthouse_ID.txt file will be unique to the memory card onto which it was saved (i.e. inserting another microSD memory card into the MFD's memory card reader will cause a slightly different Lighthouse_ID.txt file to be stored on the second microSD memory card).

In order to download LightHouse Charts which have been purchased from the LightHouse Charts Store, a microSD memory card having a Lighthouse_ID.txt file must be present with the computers memory card reader. Once downloaded from the LightHouse Charts Store, these same purchased LightHouse Charts may only be downloaded to the same microSD memory card onto which they had been originally downloaded.
