Through the RS232-USB converter cable can transfer the RS232 interface to USB port to work like a HID(Human Interface Device) class USB device. The Software applications in most operating systems can easily read data from such HID class devices without any customized drivers.
We use CH340 and FTDI chip to develop the conversion cable, which can realize the conversion of USB to serial interface. Users only need to install the driver to use.
RS 232 is a recommended standard protocol for serial data transmission between the electronic devices. It mainly works on three line signals: a transmission line, receive line and ground. It is therefore very simple to create your own software to communicate with the Rangefinder Module from Window or Linux. The typical UART output uses a serial RS232 with standard communication transmission protocol, which is the most common configuration for PC serial communication nowadays.
