Note Please don’t change the DIP-switch setting when UTP or fiber port
is transmitting or receiving data. It may cause some data error.
Besides, if you change the DIP-switch setting, please power off
the converter and power on again to make the setting effective.
Ports
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 unit 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.
