serial port to usb converter

1 Product 2. Features The main function of this product is to monitor the communication data in the serial line. It is very suitable for serial programming staff. By capturing the serial communication data, we can analyze the communication protocols or data of hardware and software, the biggest advantage of this product is to capture its data without damaging t

IntroductionThe serial port is a very common protocol for device communication (not to be confused with the Universal Serial Bus Universal Serial Bus (USB)). Most computers contain two RS232-based serial ports.

In Linux, all the device files are generally located under "/dev", serial 1 and serial 2 corresponding to the device name "/dev/ttys0", "/dev/ttys1", and USB to the serial port device name is usually "/dev/ttyusb0", The operation of the device under Linux is the same as for

Currently, General laptops do not have a serial port interface. When debugging and debugging the Development Board or other embedded devices, USB to serial port is a good choice, you can debug the Development Board and download files. However, in special circumstances, some

The hardware engineer said that the CAN box would certainly be sent, and it had to be around for a long time, at last, we can only connect the USB to the serial port board to the computer to see that there is data, bu
