4.2.1. “IMU” tab of “Devices options…” window
There are options for the Inertial Measurement Unit (IMU). You can check or
set the following parameters in the “IMU” tab of the “Devices Options”
window Fig. 4.2:
IMU type – shows type of IMU inside the INS unit. This parameter
cannot be changed.
COM Port bps – sets baud rate of the main INS COM port (see
section “4.2.7. Change of the main COM port baud rate” for details). Default
value is set to 115200 bps.
Data rate (Hz) – sets output data rate in Hertz. Minimal value of the
parameter is 1, maximal value is 200; it is changed with the arrows to 10 or
by entering the required value from a keyboard. Default value is set to 100.
Important note: the maximum data rate is limited by chosen baud rate of the COM port
which the INS unit is connected to, and also it depends on chosen output data format
(see Fig. 4.1) because of different number of transferred bytes. See section “4.2.8.
Limitation of the INS maximum output data rate” for details.
Fixed checkbox limits data rates to be factors of 200 Hz: (1, 2, 4, 5,
8, 10, 20, 25, 40, 50, 100, 200) Hz.
Initial alignment time (sec) – sets the initial alignment time in
seconds. The INS output data will be displayed in respective windows only
after the time set in this parameter is over. During initial alignment the INS
