4.2.2.11 "SPOT GEN3 emulation.
The ST100 board has the ability to emulate the tracking and messaging modes of a SPOT GEN3 device for particular
applications.
Refer to document (number TBD) "ST100 SPOT GEN3 emulation modes" for details on how to use these modes.
4.2.2.12 Special consideration for "Byte 7" in the next several commands.
The following commands cause the ST100 to transmit either a single busted message, or to enter track mode or to
modify a track mode, wherein bytes 1,2,3,4,5 and 6 of the over the air message contain the latitude and longitude
location data.
The user may set bytes 0, 7, and 8 (and subsequent packets in the case of the "Send Redundant Burst with GPS" (0x33)
command) to any value of his choosing with a special exception for "byte 7".
The commands for which this rule applies are:
0x30 - Proprietary Track
0x33 - Send Redundant Burst with GPS
0x34 - Proprietary Motion Activated Track
0x35 - Proprietary Motion Activated Dock
In any of the above modes, if the user specifies a value for "Byte 7" with the most significant 4 bits all ones ((<byte 7> &
0xF0) = 0xF0) the following special behavior is activated:
The 4 most significant bits of byte 7 become status flags with the meanings as follows:
