Ethernet Ports
 RJ-45
RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for
10Base-T or 100Base-TX 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.
RJ-45 Pin Assignments
Pin Number Assignment
1 Tx+
2 Tx-
3 Rx+
6 Rx-
Note
“+” and “-” signs represent the polarity of the wires that make up
each wire pair.
All ports on this industrial switch 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 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-)
