USB to RS232 serial cable is a serial communication converter that allows users to connect to the computer through the USB interface and connect to external devices using the standard RS232 serial port.

Product Description 

1. USB interface: used to connect to a computer or other USB host device.

2. RS232 serial port D-Sub 9-pin DB9 male connector: Connect to the device that requires communication through the standard RS232 serial port.

3. USB conversion circuit: Converts USB interface data to RS232 serial port data, realizing communication conversion between USB and RS232.

4. Driver chip: Usually there is a built-in USB to serial port driver chip, originally imported from the UK FTDI FT232RNL+UM213, so that the device can be automatically recognized and the corresponding driver installed when it is plugged into the computer.

Application to be used:

1. Connect old serial devices : 

This product is suitable for connecting old serial devices, such as modems, serial printers, POS devices, etc. These devices usually have RS232 serial ports, and modern computers are usually no longer equipped with RS232 serial ports, so they need to be connected via USB converter connection.

2. Industrial control equipment : 

In the field of industrial automation, there are many control equipment that use RS232 serial ports for communication. USB to RS232 products can connect these devices to modern computers for monitoring, control and data collection.

3. Embedded system development : 

During the development process of embedded systems, it is often necessary to communicate with RS232 serial port devices, such as connecting to embedded controllers or other embedded devices. USB to RS232 products can easily communicate with these devices. communication.

4. Debugging and testing : 

This product can also be used for debugging and testing serial port equipment. By connecting to a computer, you can easily monitor and debug the data in the serial communication process.

5. Data collection and monitoring : 

Various serial devices can be connected to the computer for data collection and monitoring, such as sensors, instruments, etc., and the computer can be used for data processing and analysis.
