All ports on this Industrial switch support the automatic MDI/MDI-X operation, and users
can use straight-through cables (See figure below) for all network connections to PCs or
servers, or to other switches or hubs. With straight-through cable, pins 1, 2, 3, and 6, at
one end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other
end of the cable. The table below shows the 10BASE-T/100BASE-TX/1000BASE-TX
MDI and MDI-X port pin outs.
Pin MDI-X Signal Name MDI Signal Name
1 Receive Data plus (RD+) Transmit Data plus (TD+)
2 Receive Data minus (RD-) Transmit Data minus (TD-)
3 Transmit Data plus (TD+) Receive Data plus (RD+)
6 Transmit Data minus (TD-) Receive Data minus (RD-)
The following figures show the cable schematic for both straight-through type and
