RJ-45 ports (Auto MDI/MDIX)
: The RJ-45 ports are auto-sensing for
10Base-T, 100Base-TX or 1000Base-T devices connections. Auto
MDI/MDIX means that you can connect to another switch or workstation
without changing straight through or crossover cabling. See figures as
below for straight through and crossover cable schematic.

Note
“+” and “-” signs represent the polarity of the wires that make up
each wire pair.
All ports on this industrial switch converter support automatic
MDI/MDI-X operation, you can use straight-through cables (See Figure
below) for all network connections to PCs or servers, or to other
switches or hubs. In 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-T MDI and MDI-X port pin outs.
