When it comes to the USB interface, everyone must be very familiar. Isn’t this a common USB interface that mobile phones should see?
Yes, the USB interface is used in conjunction with the USB cable. But what is the specific function of the USB interface of the industrial computer? we believe that some new customers are still not very understanding of this. Please follow the steps of the following explanation!
1. Definition of USB interface
USB, short for Universal Serial Bus in English, is an external bus standard used to regulate the connection and communication between computers and external devices. It is an interface technology applied in the PC field. The USB interface supports plug-and-play and hot-plugging of the device. It was jointly proposed by Intel, Compaq, IBM, Microsoft, and other companies at the end of 1994.
2. The difference between USB2.0 and USB3.0
In order to distinguish the two interfaces of USB 2.0 and 3.0 in the industrial computer, please pay attention to the colors of these two: 3.0 selection of USB interface, the core is blue. If it is a 2.0 selection, the USB interface is generally black or white.
3. The function of the USB interface
Our common industrial computer USB interfaces are used:
1) USB mouse, keyboard equipment, box, gamepad;
2) Industrial printers, scanners;
3) Camera, data flash disk, SD connection slot;
4) External optical drive, mobile hard disk, mobile phone charger, USB network card;
5) Communication equipment ADSL Modem, Cable Modem.
In addition, there is a USB interface that can also be connected to a USB night light, a USB small fan, a USB heater, etc., with a charging function. However, I rarely use the USB interface to do these small things on the industrial computer.

To sum up, the USB interface and COM serial port of the industrial computer are both used on external devices and have similar basic functions. It is necessary to choose whether the industrial computer uses the USB interface or the COM serial port according to the standard interface on the external device.
However, in the vibrating industrial site, the interface of the industrial computer and the external interface device is required to be connected stably. Generally, the USB interface is not used, but the COM serial port is used because the double nut can be used for locking in the COM port.
