5. Set the Link Test/MissingLink button to LNK TST (OUT) position.
6. Set the auto-negotiation feature as follows:
❑ If both end-nodes will use auto-negotiation to determine the duplex
mode, or if both are pre-set to operate with the same duplex mode,
such as half-duplex, set the switch to the A/N ON (IN) position. This
is the default setting.
❑ If one end-node is capable of operating at only half-duplex mode while
the other node will determine its duplex mode through auto-
negotiation, set the switch to the A/N OFF (OUT) position.
7. Plug the AC/DC power adapter into an appropriate AC power outlet and
insert the power plug into the DC receptacle located on the back of the
unit. Refer to Figure 6. This step does not apply if you installed the
unit in an AT-MCR12 chassis.

media converter’s receiver port (RX) is connected to the end-node’s
transmitter port (TX).
10. Connect the twisted pair cable to the twisted pair port.
Note
End-nodes connected to the media converter must operate with the
same duplex mode, either both full-duplex or both half-duplex.
