Transmit Preset (Message ID 2)
This message is sent to the Black Box to modify the currently selected preset or as a response to a “Request Stored Preset”
message. If this message is sent from an external device to Black Box while a user preset is selected, the preset is stored to
the selected preset location. If this message is sent from an external device to Black Box while a factory preset is selected, the
message is ignored. Regardless of whether the current preset is user or factory, a “Save Complete” message (ID 17) is sent as a
response.

NOTE : Black Box requires nearly a full second to save the received user preset to its slow flash memory. Any messages received while Black
Box is still saving the received user preset will be ignored. After the external device sends this message, it should either wait a full second or
wait until a “Save Complete” message (ID 17) is returned before sending any further messages.
