Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the Moxa
IMC-21GA’s 10/100/1000BaseT(X) ports to any kind of Ethernet device,
regardless of the type of Ethernet cable used for the connection. This
means that you can use either a straight-through or crossover cable to
connect the IMC to Ethernet devices.
