The network mouth card pressure line shows that the network interface is basically RJ45 network interface, there are two kinds of standards, 568A and 568B, respectively:
568A standard: green, white, green, orange, blue, blue, orange, brown, brown and brown
568B standard: orange, orange, green, blue, blue, white, green, brown, brown and brown
There are two other ways of network line, which are cross line and straight line.
The practice of cross line is: one head is 568A standard, one is 568B annotation.
The approach of direct line is that both ends adopt the 568A standard or both ends with 568B annotation
Whether it is a cross or a straight line, the FeiKong control network port card is supported.
