Placement IMUs ref frame

Hi, I'm working on OpenSense with some experimental IMUs, during the placement of the IMUs, all the reference frames must be the same of the base imu (pelvis) or, during the calibration the software is able to understand their orientations therefore the axis of the reference frames of the IMus can be different between one and another?

If the latter is true, for the rotation between the 2 reference frames (in the IMU placer GUI) I need to specify the rotations only of the base IMU, right?

Thank you
