Chapter 1

Overview

The AT-MC1x Series Ethernet Media Converters includes the following
models:

q AT-MC13 q AT-MC15

q AT-MC14 q AT-MC16

These media converters are designed to extend the distance of your network by
interconnecting twisted pair cabling to single-mode or multimode fiber optic
cabling or thinnet cabling. The AT-MC1x Series Media Converters allow you to
interconnect LAN devices over large distances.

The AT-MC13, AT-MC14, and AT-MC16 media converters feature a 10Base-T
twisted pair port and a 10Base-F fiber optic port. The twisted pair port has an
RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
The fiber optic port has an ST or SC connector and a maximum operating
distance of 2 kilometers (1.2 miles) to 100 kilometers (62 miles), depending on
the model. These media converters operate at 10 Mbps and feature half- and
full-duplex operation.

The AT-MC15 features a 10Base-T twisted pair port and a 10Base2 thinnet
port. The twisted pair port has an RJ-45 connector and a maximum operating
distance of 100 meters (328 feet). The thinnet port has a BNC-type connector
and a maximum operating distance of 185 meters (606 feet). The AT-MC15
operates at 10 Mbps and features half-duplex operation.

The AT-MC1x Series Media Converters can be used on a desktop or in an
AT-MCR12 chassis. These media converters are easy to install and do not
require software configuration or management.

Key Features

The media converters have the following key features:

q LEDs for unit and port status

q Full- or half-duplex mode operation (except AT-MC15)

q Half-duplex mode operation (AT-MC15 only)

q MissingLink notifies end-nodes of link failures (fiber models only)

q Link Test feature performs a link test on the media converter’s fiber

port

q MDI/MDI-X switch that eliminates the need for a crossover cable

q Internal termination on the BNC port (AT-MC15 only)

q External AC/DC power adapter

q Standard, compact size for desktop use or in an AT-MCR12 rackmount

RX Green Data is being received on the BNC port.
ONLINE Green Th e BNC port is connected to an active 10Base2 segment.
COL Green The BNC port is sensing a collision signal.

MDI/MDI-X Switch

An RJ-45 port on a 10 Mbps Ethernet network device can have one of two
possible wiring configurations: MDI or MDI-X. The RJ-45 port on a PC, router
or bridge is typically wired as MDI, while the twisted pair port on a switch or
hub is usually MDI-X.

To connect two 10 Mbps network devices together that have dissimilar port
wiring configurations, such as MDI to MDI-X, you use a straight-through cable.
To connect two network devices that have an RJ-45 port with the same wiring
configuration, such as MDI to MDI, you use a crossover cable.

The RJ-45 port on the media converters feature an MDI/MDI-X button. You can
use this button to configure the twisted pair port on the media converter as
either MDI or MDI-X, thus eliminating the need for a crossover cable
regardless of the type of network device you are connecting to the unit.

Table 4 lists the pinouts of the RJ-45 ports for both MDI and MDI-X wiring
configurations.

FIBER

LINK TEST

Fiber Link Test Switch

The AT-MC13, AT-MC14, and AT-MC16 media converters feature a Fiber Link
Test switch. This switch sets the fiber port into an artificial link transmission
state for testing without the twisted pair port being connected. When the Fiber
Link Test switch is in the DOWN (default) position, the NML LED is green
indicating that the media converter is functioning normally. For a link test, set
the switch in the UP position. Be sure to set the switch back to the default
position after performing a link test. If the switch is left in the UP position, the
media converter will not function properly. Refer to Figure 2 for the location of
the Fiber Link Test switch.
