❓ Does this card support the Kylin system?

 ✅ It supports Kylin, UnionTech and other Linux systems for use.

❓ Does this card require the installation of drivers? Can it be used with the Win7 system? 

✅ Yes, it can be used after installing the drivers. The method for installing Windows drivers can be found in the detail page introduction.

❓ Can Linux systems use it without drivers? 

✅ The RS232 serial card supports using the system's built-in kernel drivers, so it can be used without installing drivers. However, RS422/RS485 serial cards with PCI_E and miniPCE interfaces require the installation of drivers for use.

❓How to simply test if the serial port is working and communicating?

    

❓ How to install drivers on Linux systems? Are there any tutorials?

❓ What is the interface definition of this serial card? 

✅ The pin definitions for RS422 are as follows:

1—RXD-

2—TXD+

 3—RXD+

4—TXD-

5—GND

6—Empty (VCC is not used in this product)

The pin definitions for RS485 are as follows: 

1—Empty

2—TX/RXD+(A)

3—Empty

4—TX/RXD-(B)

5—GND

6—Empty

❓ How can I download the drivers? Which drivers are used? I can't find them on the official website. 

✅ Search for our official website's driver download address on Baidu: http://www.mmui.com.cn/data/upload/image/EXAR352_354_358.zip. Scroll down to find EXAR/352/354/358 and download and install it.
