Product Description

1. INTRODUCTION

Crafted to meet the highest standards, our product adheres to the MODBUS communication protocol, leveraging the sub-centralized RTU mode and the highly efficient RS485 half-duplex working mode within the MODBUS framework.

Serial Port Configuration: Ensuring seamless communication with settings of no parity, 8 data bits, and 1 stop bit.
Example Configuration: 9600, N, 8, 1 Explanation: Operates at 9600bps with no parity, 8 bits of data, and a single stop bit, ensuring robust performance.
Versatile Baud Rate Support: Our transmitter is engineered to handle a broad array of serial baud rates including 1200, 2400, 4800, 9600, 19200, 38400, 57600, and up to 115200.
Advanced Error Checking: Employing the CRC checksum polynomial: 0xA001 for enhanced data integrity.
Data Processing Excellence: Communication is executed utilizing double-byte shaped data. For floating-point numbers, the decimal point is read to accurately determine data magnitude.

Installation Instructions

When modifying the baud rate, the transmitter will reply with the baud rate sent by the host to modify the data. Upon reply, the transmitter's baud rate will immediately update to the new target value.
Upon modifying the address, the transmitter will confirm by replying with its current address. Following this confirmation, the address will automatically update to the new specified value.
When the factory command is saved and replied, the original value will be returned, indicating that the transmitter has successfully received the command from the host.
Please note that restoring factory data may result in differences from user-saved parameters. This affects the address, baud rate, and calibration data. Re-scan the transmitter after restoring factory settings to ensure accurate parameters.
The user is permitted to modify only three specific data points: address, baud rate, and zero offset.
For calibration or changes to calibration data, contact our company to obtain the transmitter's calibration software. Self-modification of calibration data via user commands will trigger an exception code. Always use our provided calibration software for any changes.
Reading data identified as a floating point number (e.g., 6.000) but transmitted as integer data (e.g., 6000) requires recalculating the decimal point. For example, a decimal point of 3 would mean 6000/10^3, resulting in 6.000.
