IMU 5DOF. HELP? HOW TO WORK IT?

Hello I have an IMU 5DOF, that integrates an ADXL330 Accelerometer and IDG300 Gyro. I dont know how to work the IMU. how does the IMU work, how does it sense the tilt and position and how do i obtain the output. how do i connect it to the computer. i dont have any sort of software interface to communicate with the IMU. what kind of circuit to i have to construct to connect it to the computer. is there any way i can communicate with the IMU without PIC?? I have gone through the data sheet but dont understand these basic newbie questions.pls help. thank you
