Overview
The Allied Telesyn AT-MC101 and AT-MC102 are 100Base-TX/100Base-FX
media converters. They convert Fast Ethernet signals from twisted pair cable
to fiber optic cable and vice versa, providing seamless connection between two
different media. An external 12 VDC power adapter supplies power to the
media converters. The AT-MC101 has ST connectors; the AT-MC102 has SC
connectors. See Figure 1 and Figure 2.

MDI/MDI-X Switch
The MDI/MDI-X switch located on the front of the unit, is a straight-through or
crossover cable selection switch. It enables the 100Base-TX (RJ45) port to be
connected to a repeater or to a DTE without using a special crossover cable.
The default setting of the switch is MDI-X, which means you can connect the
100Base-TX port to a workstation or to any other DTE that uses a straight-
through cable.
In the MDI configuration, slide the switch to the MDI side and connect the
100Base-TX port to a repeater/hub/switch using a straight-through cable.
