Overview
This document provides technical specifications and operational procedures for the AKG392 MEMS Digital Vibration Sensor. It includes instructions for setting sensor parameters, communication protocols, and data interpretation.
Specifications

  • Effective address range is 1 to 247, and it supports CRC16 data checks.
Procedures
  • Setting Commands: Commands must be sent twice consecutively to be effective. Settings are not saved after power-off unless a save command is issued.
  • MODBUS Protocol: Requires a minimum 10ms interval between data frames. Broadcast address 0 can be used for setting multiple sensors simultaneously.
  • Data Types: Includes short, ushort, int, and uint with specific read-only registers for temperature, acceleration, vibration frequency, speed, and amplitude.
Data Interpretation
  • Data values are calculated by multiplying register data by a coefficient.
  • Example provided for converting acceleration data from hexadecimal to decimal and applying accuracy coefficients.
Commands and Examples
  • Set Sensor Address: Example provided for changing the sensor address with CRC checksum verification.
  • Set Baud Rate: Instructions for setting baud rate with examples for different rates.

  • Set Bandwidth: Command to adjust sensor bandwidth with valid values provided.
Recommendations
  • Ensure commands are sent twice consecutively for settings to take effect.
  • Allow a 10ms interval between data frames to ensure proper communication.
  • Use broadcast address for simultaneous sensor configuration when needed.
