Application of USB Serial Port in Instrumentation Industry

What is the USB serial port? In fact, the USB to serial port is not difficult to understand, the computer and device COM port data conversion, in order to achieve data communications, which can provide a convenient and efficient channel for the computer does not have a serial port. Today we mainly introduce the USB serial port application in the instrumentation industry, hoping to help everyone understand the product.

USB serial cable is widely used in industrial automation, instrumentation, MCU and so on. In the industrial control industry, the quality and function requirements for USB to RS232 or USB to RS485 serial lines are very high, such as system compatibility, resistance to voltage, and anti-static functions.

HighTkeHU-04USB to RS485/422 serial line industrial control industry engineers love a USB serial line, this product has the following characteristics:

1.Using original British FTDI chip, Super compatible with Win7/Win8/Android/2000/xp/vista/CE/Linux/Mac and other operating systems;

2. Support RS485 full-duplex 422 half-duplex, more to meet the needs of customers;

3. The use of industrial design solutions, can be -25 °C to 70 °C, relative humidity of 5% to 95% of the application;

4. Each line has 600W lightning protection and ±15KV electrostatic protection, which greatly improves the anti-jamming capability of the product and effectively protects our system.

How to troubleshoot that the USB serial cable cannot communicate with the device properly for the following reasons:

1. Check if it is installed.

How to check whether the USB serial cable driver is installed? Check whether there is a question mark on the COM port under the “Device Manager”. If there is a question mark, it is not installed. Otherwise, it is installed.

How to install the USB serial cable driver? For example: HighTekHU-01USB to RS232 First, the HighTek driver CD copies the HU-01HU-09 model driver and extracts it. Then plug our USB serial cable into the computer interface and right-click on the computer - "Administration ---" Device Manager - "Other Devices -" Right-click "FT232RUSBUART" - "Update Driver -" Select Manually Add --"Find HU-01 Driver--"System--"Click Next;

2. Many devices default COM port is COM1, if it can not communicate, you can modify it in the Device Manager - "Port -" USB serial line COM port - "Properties -" Advanced - "COM port;
