The Oceanic Pro Plus X is quite different from the previous models. The profile data is now stored in a dedicated memory area, and hence there are a few important differences: Reading data from the new profile memory area is done with a new F6 command. This new command is very similar to the existing B8 command, but accesses a completely different memory area. In order to integrate those two memory areas as transparantly as possible into the existing infrastructure, a virtual memory space is introduced. The lower part of the virtual memory is mapped onto the main memory area, while the upper part is mapped onto the new profile memory area. The page size of the new profile memory area also increased from 16 to 256 bytes. If the profile size is not an exact multiple of 256 bytes, the dive computer pads the profile data with 0xFF bytes. The other changes are the usual Oceanic device specific changes.
