4.2.8. Limitation of the INS maximum output data rate
When setting of the measurement rate for the INS unit in the “Devices
Options”, “IMU” tab (see Fig. 4.2) it is essential to ensure the chosen baud
rate is capable of handling the data throughput with desirable data rate. The
maximum measurement rate (Hz) can be calculated using the baud rate and
data package length:
ngthpackage_le * ytebits_per_b
ateCOM_baud_r
atemax_meas_r 
, (4.1)
where COM_baud_rate is COM port baud rate (bits/s); bits_per_byte = 11
bits per one transferred byte of data; package_length for binary data =
payload length plus 8 bytes of overhead. See Appendix C, Tables C.3, C.7
to C.11, C.13, C.19, C.20, C.25, C.26 for payload length of binary output
data formats. The package_length of the text output data formats
correspond to their structure shown in Appendix C.
Table 4.1 contains data package length for each output data format and also
maximum measurement rate calculated by formula (4.1) with some spare.
Note the maximum measurement rate of INS data is limited by 200 Hz.
