1.Introduction
The CMCU-06 is an industrial-grade single-channel RS485 strain gauge transmitter launched by Shenzhen RunesKee Technology Co., Ltd. It is compact, stable, and reliable, making it suitable for equipment control, sensor data acquisition, and other scenarios requiring communication via the RS485 serial port.
Features include:
- Power supply range: 12V~24V version / 5V version;
- Operating environment: -40℃ to 85℃;
- Supports 1 RS485 serial port;
- Low power consumption: below 0.1W;
- Communication format: Baud rate 9600 (adjustable), 8 data bits, 1 stop bit, no parity;
- Communication protocol: MODBUS-RTU protocol, supported function codes: 03, 06, 16 (0x10);
- Resolution: 1/50,000 division;
- Address range: 1–247, default is 1;
- Configurable parameters include sampling frequency, division value, baud rate, zero-tracking range, zero-tracking enable, average filtering, dynamic tracking range, creep tracking, etc., making it adaptable to most applications.
For a quick start guide after receiving the device, refer to "Strain Gauge Transmitter - Quick Operation Guide Upon Arrival."
Note: The screen version adds a display screen to the non-screen version and includes software for synchronizing units to the display. The manual parameters remain the same.
