Features
Here are the features of the DMC1000/100 Series Mini Media Converters:
Provide a smaller-sized space-saving alternative that allows
enterprises to connect 1000Mbps fiber networks to 1000Mbps
copper networks or connect 100Mbps fiber networks to 100Mbps
copper networks, offering a cost-effective method for integrating
fiber-optic cabling into a 10/100/1000 or 10/100 UTP environment.
See Table 1 for the specifications of each model.
The AT-DMC1000/SC, AT-DMC1000/ST, and AT-DMC1000/LC
models operate at 1000Mbps full duplex.
The AT-DMC100/SC, AT-DMC100/ST, and AT-DMC100/LC
models operate at 100 Mbps full duplex.
Can be installed on a desktop or wall-mounted
Note
Wall-mounting equipment is ordered separately as a five-pack
package: five mounting brackets for five media converters.
Smart MissingLink™ (SML) to set with the DIP switch
Missing Link (ML) to set with the DIP switch for the V2 series media
converters.
Powered via a Micro-B USB 5VDC connector, from a PC USB port,
or with the optional AC/DC power adapter
Support for Jumbo frames up to 16kB
LEDs for unit and port status

Twisted-Pair Port Here are the basic features of the twisted-pair port:
1000Base-T compliant for AT-DMC1000/SC, AT-DMC1000/ST,
and AT-DMC1000/LC
100Base-TX compliant for AT-DMC100/SC, AT-DMC100/ST, and
AT-DMC100/LC
IEEE 802.3u Auto-Negotiation compliant
Auto MDI/MDI-X
100 meters (328 feet) maximum operating distance
RJ45 connector
Note
For the port pinouts, see “RJ45 Connector and Port Pinouts” on
page 59. For cabling specifications, refer to “Planning the
Installation” on page 39.
Auto
MDI/MDI-X
An RJ45 twisted-pair port on a 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI or MDI-X. The RJ45
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.
The media converter features Auto MDI/MDI-X. The twisted-pair port
automatically determines the configuration of the port on the device to
which it is connected and then configures itself appropriately.
For example, if a port on a media converter is connected to a port on a
bridge, which is typically wired as MDI, the port on the media converter
automatically configures itself as MDI-X.
This feature allows you to use a straight-through cable when connecting
any type of device to the media converter, regardless of the wiring
configuration of the port on the device.
Fiber-Optic Port For maximum operating distance for the fiber-optic port, see “Fiber-Optic
Port Specifications” on page 61.
Power Source The media converter is powered via a Micro-B USB connector and
provided Micro-USB to Type-A USB cable. The power source can be a PC
USB port or the optional external AC/DC power adapter.
Depending on the customer order, the AC/DC power adapter is included
with the media converter for standalone operation. The power adapter
supplies 5 VDC to the media converter. Allied Telesis supplies a UL
approved safety-compliant AC power adapter for the 120 and 240 VAC
versions with a regulated output of 5 VDC. The power required for the
media converter is 5 VDC, 0.5 A.
