Sounder/TSS1 Motion protocol

This proprietary

heave, roll and pitch compensation. When you select this protocol, the number of sensor
variables is fixed, and there is no token associated with it. However, baud rate and output
rate may be adjusted to fit your needs. The format is based on ASCII characters, the
datagrams have fixed length, and it is terminated with a carriage return and line feed.
The definition of the attitude angles in this format is different from the Euler angles
definition used elsewhere. The difference appears in the roll angle, where:
