    RS485 Protocol

    • Communication Standards

    • Baudrate 115,200 Data Bits 8
      Stop Bits 1 Parity None

    • Data Format (ASCII)

    • =[ID_mode+scale_X_Y_Z]+Checksum+CR
      e.g. [1 01 900 50 1700]12

      • _ means space, + means non-space.
      • Every echos (return messages) received in a pair of square bracket [ ].
      • Check Sum : Substitute ASCII of each bytes for HEX and calculate by XOR.

    • Commands

    • Carriage Return and Line Feed must be attached to end of commands. Every commands must be upper cases.
      e.g. <1 START>53+CR+LF

      <@> Measure data once.
      <@ START> Measure data continuously.
      <@ STOP> Stop measuring.
      <@ ID #> Set ID from @ to #
      <@ SPEED #> Baudrate setting
      <@ MODE #> Data mode setting
      <@ SCALE #> Scale (dps) setting
      <@ INTERVAL #> Data out-rate setting
      <@ CALI> Bias calibration
      <@ INIT> YAW deg zero-set
      <@ SAVE> Save configurations
      <@ RESTORE> Factory reset

    • @ : Sensor ID, # : S/V
    • Set ID
      Default ID is 1. To parallel connect multiple sensors, set every sensor IDs before connect. ID can be set within 1...254.

    • Baurdrate setting
      Default Baudrate is 115,200bps. Baudrate can be set by S/V as following table. If send command without S/V, current value will returned.

    • 1 115,200
      2 57,600
      3 38,400

    • Data mode setting
      Choose angle data or angular velocity data. Default vaule is 0. If send command without S/V, current value will returned.

    • 0 Angle (deg x10)
      1 Angular Velocity (mdps)

    • Scale (dps) setting
      Default scale is +/-250 dps. If send command without S/V, current value will returned.

    • 1 +/-250
      2 +/-500
      3 +/-2,000

    • Date out-rate setting
      Default out-rate is 100ms. Out-rate can be set within 10...1,000ms by 10ms of unit. In Angular Velocity mode, out-rate is fixed by 10ms. If send command without S/V, current value will returned.

    • Bias calibration
      Calibrate bias of the sensor. This may affect critically to sensor accuracy. Calibrate only if absolutely necessary and keep sensor stably during calibrating.

    • YAW deg zero-set
      Set YAW (Z) axis current position to zero. Gyro sensor YAW axis occurs zero-position-drift continuously because it keeps calculating integral calculus for its zero position. This is a characteristic of MEMS gyro sensor.

    • Save configurations
      Save ID and configurations. ID and any configurations will be initialized when shut power off without save.


    Ordering Code

    NOTES

    • Ground connection is recommended in noise occurred environment.
    • RS485 protocol may cause delay or crash by internal processing time and other reasons. If commanding is not in real-time, repeat sending the command.
    • Check wiring connections before use.
    • 12 months warranty is provided after released. Warranty provided only in case of using for designed purpose correctly.
    • Specifications, design and components can be changed without prior notice to improve its performances.
