    Remark 1: resolution is the smallest angular increment at which a detectable change in output can be measured.

     

      V. Digital Output of The Angle

    1. RS485 serial port setting:

    Baud rate: 9600bps, one start byte, eight data bytes, one stop byte, and no parity byte.

    2. Output format of the angle:

    There is nine bytes of a group output data.

    Byte1: 0x2A

    Byte20x2B/0x2D

    Byte3thousands of the angle (ASCII)

    Byte4hundreds of the angle (ASCII)

    Byte5tens of the angle (ASCII)

    Byte6units of the angle (ASCII)

    Byte70x2E

    Byte8tenths of the angle (ASCII)

    Byte90x0F

    Eg: the current angle value is +3.6 deg, the display of the hexadecimal is:

    2A 2B 30 30 30 33 2E 36 0F

    Note:

    When the measured angle is out of the range, it will display:2A 2B 30 38 38 38 2E 38 0F.

     

    VI. User Commandsthe following commands is hexadecimal

    1. 0x1A 0x0C XX 0x0D ―― Set address of the sensor’s axes. Successful setting will get a return value of 0x2A 0x0C XX 0x0F, XX represents the sensor’s axes’ address, which can be valued from 0×01 to 0×20, factory default address is 0×01;
    2. 0x1A 0x1C XX 0x0D ―― Set the current angle as zero position. Successful setting will get a return value of 0x2A 0x1C 0x0F, XX represents the sensor’s axes’ address;
    3. 0x1A 0x0E NN 0x0D ―― Set filter parameter. NN can be valued 0×01(the fastest) /0×02/ 0×03 /0×04(the slowest). There is no return value after successfully set, and the sensor get into the ready state;
    4. 0x1A 0x1E XX 0x0D ―― Read the tilt angle, XX represent the sensor’s axes’ address, and the return value can be referred to the digital output of the angle.

    5. Attentions when mount the sensor

    ① The sensor should be mounted vertically. When the lead cable is toward to right, sensor is in the zero position. Rotate the sensor in clockwize, the angle will increase.

    ② Incorrect installation methods will lead to the measurement error. In order to minimize the mount error, please make sure the sensor perpendicular with the horizontal plane.
