    Wiring Connection

    Color Diff.Vdc / mA RS485
    RED V+
    BLACK GND (COM)
    GREEN 0.5~4.5Vdc / 4.12~19.68mA A (T+)
    WHITE N.C B (T-)
    • MSENS series is wired by MG610331-5 plug (Korea Electric Terminal Co., Ltd.). The plug can be deleted or wired with MG64REC (separately sold) according to specifications.

     

     

     

    Sensing Directions

    • Above images show sensing directions of MSENS-AC.

     

     

     

    RS485 Protocol
    • Communication Standards
    Baud rate 115,200 Data Bits 8
    Stop Bits 1 Parity None
    • 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
      e.g. <1 START>53+CR+LF
      • Carriage Return and Line Feed must be attached to end of commands. Every commands must be upper cases.
      • @ : Sensor ID, # : S/V
    <@> 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
    • 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 Enable/Disable applying Extended Kalman Filter. Default value is 0. If send command without S/V, current value will returned.
    0 Enable filtering
    1 Disable filtering
    3 High_pass_filter

     

    • Measuring range setting
      Default measuring range is +/-2g. If send command without S/V, current value will returned.
    2 ±2g
    4 ±4g
    8 ±8g

     

    • 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.

      •  

    • 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.
