    RS485 Protocol

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

     

    • Communication Standards

    • Data Format (ASCII)

    • =[ID_mode+scale_X_Y_Z]+Checksum+CR
      e.g. [1 02 -10 30 980]23
       
      • _ 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 setting
      <@ INTERVAL #> Data out-rate setting
      <@ SAVE> Save configurations
      <@ RESTORE> Factory reset

    • @ : Sensor ID, # : S/V
    1 115,200
    2 57,600
    3 38,400
     
    0 Enable filtering
    1 Disable filtering
     
    2 +/-2g
    4 +/-4g
    8 +/-8g
    • 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.

    • Data mode setting
      Choose Enable/Disable applying Extended Kalman Filter. Default value is 0. If send command without S/V, current value will returned.

    • Measuring range setting
      Default measuring range is +/-2g. If send command without S/V, current value will returned.

    • 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.

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

    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.
