Installation
1. Attach a UTP cable from the network to the RJ-45 port.
(Use screened UTP cabling for CISPR 22 class B installation.)
2. Cross-connect the fiber cables: Attach both fiber cables
TX to RX and RX to TX from the fiber network cabling to the
ST-type connectors on the MIL-C2113.
3. Apply power to the unit:
A. Insert the power adapter’s receptacle into the power plug.
B. Insert the power adapter into a wall outlet.

Link Sentry Configuration
The Link Sentry feature on the MIL-C2113 is configured through
a 4-position DIP switch (refer to Table 1).
The following table displays the Link Sentry dip switch settings needed when the
MIL-C211X is installed in a single media converter environment (not back to back).

MDI-X/MDI Switch
The MDI-X/MDI switch allows for quick configuration
of the 100BASE-TX port. Cables used when the switch is
in the MDI-X position (the “left” position:
For a hub/repeater, use a swap cable (pins are
connected 1 to 3, 2 to 6, 3 to 1, and 6 to 2).
For a workstation/PC, use a straight-through cable
(pins are connected 1 to 1, 2 to 2, 3 to 3, and 6 to 6).

Link Sentry is a troubleshooting feature that allows MiLAN media converters
to monitor link states on both fiber and copper ports in the event of a physi-
cal link down. If a link down is detected, the converter will automatically
notify the end device of the link down by disabling the TX signal of the
neighboring port. (see Figure 2.)

Note: When connecting two MIL-C211X series converters back to
back via fiber, Dip Switches 1 & 2 should be in the “up” and 3 & 4
should be in the “down” position.

Note: The MIL-C211X media converters operate at full duplex.
Therefore, when connecting the Copper UTP port, be sure to force the
link partner to 100 Full duplex. Failure to force link partner may result
in a duplex mismatch when connecting to an auto negotiating device.
