installed and used in accordance with instructions, may cause harmful

interference to radio or television reception, which can be determined by

turning the equipment off and on. The user is encouraged to try to correct

the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and the receiver.

- Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

Changes and modifications not expressly approved by the manufacturer

or registrant of this equipment can void your authority to operate this

equipment under Federal Communications Commission rules.

Overview

The AT-MC1x Series Ethernet Media Converters includes the following

models:

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.

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.

configurations.

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.

Auto-negotiation

Auto-negotiation determines the duplex mode of the ports. The duplex mode

refers to the manner in which an end-node sends and receives data on the

network. Depending on its capabilities, an end-node can operate in either half-

or full-duplex mode. An end-node operating in half-duplex can either send or

receive data, but not both at the same time. However, an end-node operating

in full-duplex can send and receive data simultaneously. The best network

performance is achieved when an end-node can operate in full-duplex mode.

The AT-MC13, AT-MC14, and AT-MC16 media converters can operate in

either full- or half-duplex mode. However, it is important to note that the end-

nodes connected to these media converters must operate in the same duplex

mode to avoid a duplex mode mismatch which can result in poor network

performance.

Figure 1 shows an example of a duplex mode mismatch. A repeater (Unit 1),

capable of operating in half-duplex mode only, is connected to the 10Base-F

port on the media converter, while a switch (Unit 2), capable of either half- or

full-duplex mode, is connected to the 10Base-T port on the media converter.

Figure 1 Example of a Duplex Mode Mismatch

In attempting to auto-negotiate with Unit 1, the media converter will

determine that the repeater is capable of half-duplex only and will set the port

connected to the unit appropriately. In auto-negotiating with Unit 2, the

media converter will determine that the switch can manage full-duplex and

will set the port connected to the switch to full-duplex. The result is a duplex

mode mismatch, with one unit operating in half-duplex and the other unit

operating in full-duplex. You can resolve the duplex mode mismatch by

manually configuring Unit 2, if possible, so that the port connected to the

media converter is set to half-duplex.

MissingLink

The MissingLink feature enables the ports on the media converter to pass the

“Link” status of their connections to each other. When the media converter

detects a problem with one of the ports, such as the loss of connection to a end-

node, the media converter shuts down the connection to the other port, thus

notifying the end-node that the connection has been lost.

For example, if the network twisted pair cable on an AT-MC14 were to fail, the

module would respond by dropping the link on the fiber optic port. In this way,

the AT-MC14 notifies the end-node connected to the fiber optic port that the

connection on the twisted pair port has been lost. If the failure had started with

the fiber optic cabling, the unit would drop the link to the twisted pair port.

The value to this type of network monitoring and fault notification is that some

hubs and switches can be configured to take a specific action in the event of the

loss of connection on a port. In some cases, the unit can be configured to seek a

redundant path to a disconnected end-node or send out a trap to a network

management station, alerting the network administrator of the problem.

Note

MissingLink is disabled when you perform a link test with the Fiber

Link Test switch. Consequently, to ensure that MissingLink is enabled

on the media converter, always set the Fiber Link Test switch to the

DOWN position during normal network operations.

Terminator Switch (AT-MC15 Only)

The Terminator switch on the AT-MC15 media converter offers 50 Ω

termination without the use of a T-connector and 50 Ω barrel terminator. Only

end-point nodes need 50 Ω termination. Internal nodes on a thinnet segment

should be connected to the cable through standard 10Base2 T-connectors. Refer

to Figure 3 for the location of the Terminator switch.

External AC/DC Power Adapter

An external AC/DC power adapter is included with the media converter for

desktop operation (see Figure 4). The power adapter supplies 12 V DC to the

media converter. Allied Telesyn supplies an approved safety compliant AC

power adapter for the 120 and 240 V AC versions with an unregulated output

of 12 V DC at 1 A. The power requirement for the AT-MC13, AT-MC14, and

AT-MC16 media converters is 12 V DC, 500 mA. The power requirement for the

AT-MC15 is 12 V DC, 300 mA

Note

The power adapter is not used if you install the media converter in an

AT-MCR12 chassis.

Network Topologies

The AT-MC1x Series Media Converters can be used in two different topologies:

standalone and back-to-back. Both types of topologies are described below.

Standalone Topology

A standalone topology uses one media converter between the end-nodes. Figure

5 illustrates a standalone topology that uses an AT-MC13 media converter to

connect two switches.
