Portable ultrasonic depth sounder KWD100

1. Product introduction

The portable ultrasonic detector KWD100 is a handheld terminal computer developed for portable carrying and measurement. It is light in appearance, durable in structure, easy to operate, simple, and intuitive, which greatly improves work efficiency and user experience, and can be adapted to use in various environments.

This product is based on the principle of ultrasonic ranging and can realize underwater ranging and underwater depth measurement functions. The feature of this product is that it can use the transducer attached to the machine for depth measurement; it can also be used for external power supply and external communication. The company's various ranging sensors or transducers carry out corresponding ranging work. The parameters of each ultrasonic transducer are different to cope with different occasions. This product can read the signal waveforms of the transducer and sensor, which is convenient for personnel to make relevant judgments.

4. Agreement Description

port parameters

The hardware adopts RS-485, master-slave half-duplex communication, the host calls the slave address, and the slave responds to the communication

Data frame: 10 bits, 1 start bit, 8 data bits, 1 stop bit, no parity;

Baud rate: 9600 19200 38400 115200 (default 115 200).

Reading a single register

Function code: 03H

Host sends
