All ports of RNS5/8 support the auto-MDI/MDI-X function. When you use an
Ethernet cable to connect other devices, such as computers, switches or hubs, pin
1, 2, 3, and 6 of the 8-pin RJ45 connector are used to communicate with the
connected devices. Pin1, 2, 3, and 6’s signals are converted by the MDI-X function,
as shown in Table 2.
