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
LEDStateColorDescription
PWRONGreenPower is applied to the media converter.
RECONGreenData is received on the port.
LNKONGreenA 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.

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.
