Data Sheet

According to descriptions on 'Roll, Pitch, Yaw' Object on page 28, the first four bytes represent an unsigned 32-bit integer

0x1338f5a0 (which is 322500000 in decimal), which means the time stamp is 322.500000 seconds.

The fifth to the eighth bytes represents an IEEE-754 Floating Point number 0x3f04b6af (which is 0.51841253 in decimal),

which means the Roll angle measured is 0.51841253 degree.

The last red part '92b9' represents the CRC checksum number 0xb992, which is the result when apply Modbus-Style 16-bit

CRC checksum arithmetic to the data array '1423ec4100a0f53813afb6043f6d5200bff3809941'.
