M-G550-PR imu (inertial measurement unit) rs422 interface ? general description the M-G550-PR is a small form-factor iner tial measurement unit (imu) with 6 degr ees of freedom: triaxial angular rates and linear accelerations, and provides high-st ability and high-precision meas urement capabilities with t he use of high-precision compensation technology. a variety of ca libration parameters are stored in a memo ry of the imu, and are automatically reflected in the measurement data being sent to the applicati on after the power of the imu is turned on. with a rs-422 interface supported for host communication, the M-G550-PR reduces technical barriers for users to introduce inertial measurement and minimizes design resources to implement inertial movement analysis and control applications. this unit is packaged in a water-proof and dust-proof metallic case. it is suitable to use for industrial and heavy duty applications. the features of the imu such as high stability, high precision, and small size make it easy to create and differentiate applications in various fields of industrial systems. ? features item specification note sensor integrated sensor seiko epson i nertial measurement sensor (m-g350-pd11) low-noise, high-stability gyro bias instability: 6 deg/hr angular random walk : 0.2 deg/ hr initial bias error : 0.5 deg/s (1 ) 6 degree of freedom triple gyroscope : 300 deg/s tri-axis accelerometer : 3 g 16bit data resolution calibrated stability (bias, sc ale factor, axial alignment) sampling rate 1000sps (max) selectable interface protocol rs-422 (tx/rx pair, duplex transmission) bit rate 460.8kbps cable length 250m max.
