Overview

The AT-LMC10 Series Ethernet Media Converters include the following models:
AT-LMC10SC
AT-LMC10ST
The AT-LMC10 Series Ethernet Media Converters are designed to extend the distance of your network by interconnecting LAN devices that are physically separated by large distances. These media converters have the functionality to connect any managed/unmanaged 10Mbps switch or hub using standard 10Base-T RJ-45 connections and convert the signal to 10Base-FL fiber.
Each AT-LMC10 Series media converter features a 10Base-T twisted pair port and a 10Base-FL 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 a multi-mode ST or SC connector and a maximum operating distance of 2 kilometers (1.2 miles). These units operate at 10 Mbps and feature half- and full-duplex operation.
The media converters can be installed on a desktop or in an AT-MCR12 chassis. The AT-LMC10 Series Media Converters are easy to install and do not require any software configuration or management. Figure 1 and Figure 2 display the front panel of the AT-LMC10 Series Media Converters.

Table 2 Status LEDs
LED State Color Description
PWR ON Green Power is applied to the media converter.
REC ON Green Data is received on the port.
LNK ON Green A link has been established on the port.

MDI/MDI-X Selector 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 converter features an MDI/MDI-X switch. You can use this switch to configure the twisted pair port on the media converter as either MDI or MDI-X. This feature allows you to use a straight-through cable regardless of the type of end-node connected to the port.

Page 14
Overview
Note
After using the MDI/MDI-X switch to change between the two settings, you must reset the media converter by powering OFF then powering ON the unit.

External AC/DC Power Adapter

An external AC/DC power adapter is included with the media converter for standalone operation. The power adapter supplies 12VDC to the media converter. Allied Telesyn supplies an approved safety compliant AC power adapter for the 120 or 240V AC versions with an unregulated output of 12VDC at 1 A. The power required for the media converter is 12VDC, 500 mA.
