CMCU-05A: A Compact RS485 Thin-Film Pressure Display for Real-Time Sensing

1.Introduction

The CMCU-05A is an industrial-grade single-channel RS485 thin-film pressure display launched by RunesKee Technology. Compact, stable, and reliable, it can collect data from thin-film pressure sensors, display pressure values, and supports switching between three pressure units: grams (g), kilograms (kg), and Newtons (N). It also supports communication with devices via USB interface and TTL serial port.

Features include:

  • USB power supply/charging range: 5V;
  • Operating environment: -40℃ to 85℃;
  • Communication interfaces: USB serial port, TTL 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: 1/65536
  • Address range: 1-247, default is 1;
  • Configurable parameters: calibration, average filtering, baud rate, communication address, pressure value, etc.

For a quick start guide after receiving the device, refer to the "Thin-Film Pressure Transmitter - Quick Start Tutorial."

Note: The screen version includes a display screen on top of the non-screen version, but the manual parameters and software usage remain the same.
