  •  
  •  High performance MEMS based – precise gyro sensor GY100S is optimum for rough conditions of construction machinery, heavy equpiment and special vehicles by its continuous-self-diagnosis and vibration-proof abilities. GY100S excels at measuring horizontal rotation degree such as controlling turn-table which application that inclinometer (tilt sensor) cannot measure.

    RS232 Protocol

    • Baudrate (Default) : 115,200bps

    • Data Format (ASCII)
    • = Count-A:degree, V:input voltage+CR+LF
      예) 0012345-A:40.5, V12.5

      • Count is 7 digits, degree and voltage have 1 decimal point.

    • Commands

    • Carriage Return and Line Feed must be attached to end of commands.
      e.g. START+CR+LF

      BAUD # Baudrate setting
      RESET Zero-positioning
      START Measure data continuously.
      STOP Stop measuring.
      INTERVAL # Data out-rate setting
      INIT # Factory reset

    • # : S/V

      • Baudrate setting
        Default Baudrate is 115,200bps. Baudrate can be set one of 57,600 / 38,400 / 19,200 / 9,600 / 4,800. If send command without S/V, current value will returned.

      • Data 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.


    Wiring Connections

    • GY100S is wired by MG610331-5 plug (Korea Electric Terminal Co., Ltd.). The plug can be deleted when placed order.
    • To zero-positioning, short the trigger to V+.

    • Color Analog RS232
      RED V+
      BLACK GND (COM)
      GREEN Output+ Rx
      WHITE Trigger Tx

    Ordering Code

    • Format : GY100S- [output]

    • Output MV
      MA
      RS232
      0.5 ... 4.5Vdc output
      5.6 ... 18.4mA output
      RS232 output

      e.g. GY100S-MV

    • Options
      • Receptacle P/N : MG64REC
      • Cable length : additional cost per meter
      • The plug can be deleted when placed order.


    NOTES

    • Ground connection is recommended in noise occurred environment.
    • 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.
    • RS232 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.
