Insert the wires into the fault alarm contacts.
Note: Use Copper Conductors Only, Tighten to 5 lb-in
Note: The wire gauge for the terminal block should be in the range between 12~ 24 AWG.

AT-IMC100T/SCSM and AT-IMC100T/SCMM Fast Ethernet Industrial Media Converters
2.6 DIP-Switch
Table 2-2: DIP-Switch Status Description
Link Lose Forwarding (DIP-Switch 2): When LLF enabled, it allows UTP link failures to be reported to the fiber side and
also allows Fiber link failures to be reported to the UTP side. Therefore, a link fault pass-through feature is provided in both
UTP and Fiber side.
Media mode (DIP-Switch 4): When media mode is enabled (ON), it operates with the minimum latency. The transmis-
sion flow does not wait until entire frame is ready, but instead it forwards the received data immediately after the data being
received. And TP port should be forced at 100M in this application. When DIP-Switch is in switching mode (OFF), the con-
verter function is the same as a Switch Hub.
Note: Please don't change the DIP-switch setting when UTP or fiber port is transmitting or receiving data. It may cause
some data error. Besides, if you change the DIP-switch setting, please power off the converter and power on again to
make the setting effective.

RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T or 100Base-TX devices connections. Auto
MDI/MDIX means that you can connect to another switch or workstation without changing straight through or crossover
cabling. See figures as below for straight through and crossover cable schematic.
2.7.1 RJ-45 Pin Assignments
Note: "+" and "-" signs represent the polarity of the wires that make up each wire pair.
All ports on this unit support automatic MDI/MDI-X operation, you can use straight-through cables (See Figure below) for all
network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one
end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below shows

AT-IMC100T/SCSM and AT-IMC100T/SCMM Fast Ethernet Industrial Media Converters
4. Cabling Installation
4.1 Installing Copper Ethernet Cable
4.1.1 Insert one side of Category 5 cables into the Ethernet port (RJ-45 port) and another side of
category 5 cables to the network devices' Ethernet port (RJ-45 port), ex: switch, PC, or Server. The
UTP port (RJ-45) LED on the unit will light up when the cable is connected and network is active. Please
refer to the section LED Indicators for LED light meaning.
4.1.2 Connect fiber cabling as explained in paragraph 2.7.2.
4.1.3 When all connections are all set and LED lights all show in normal, the installation is complete.
4.2 Installing SFP Module and Fiber Cable
4.2.1 The cable between the link partner (switch, hub, workstation, etc.) and the converter must be
less than 100 meters (328 ft.) long and comply with the IEEE 802.3ab 1000Base-T standard for Category
5e or above.
4.2.2 Fiber segment using single-mode connector type must use 9/125ìm single-mode fiber cable. You
can connect two devices in the distance of 10km or more, accordingly with the SFP module capabilities.
Fiber segment using multi-mode connector type must use 50/125 or 62.5/125ìm multi-mode fiber cable.
You can connect two devices up to 550m distances.
4.2.3 The small form-factor pluggable (SFP module) is a compact optical transceiver used in optical
communications for both telecommunication and data communication applications.

Troubleshooting
18
AT-IMC100T/SCSM and AT-IMC100T/SCMM Fast Ethernet Industrial Media Converters
5. Troubleshooting
•Verify that you are using the right power cord/adapter (DC 12-48V), please don't use the power adapter with DC output
higher than 48V, or it will burn this converter down.
•Select the proper UTP/STP cable to construct your network. Please check that you are using the right cable. Use
unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100ΩCategory 3, 4 or 5 cables
for 10Mbps connections or 100ΩCategory 5 cable for 100Mbps connections. Also be sure that the length of any twisted-
pair connection does not exceed 100 meters (328 feet).
•Diagnosing LED Indicators: the unit can be easily monitored through panel indicators to assist in identifying problems,
which describes common problems you may encounter and where you can find possible solutions.
•If the power indicator does not light up when the power cord is plugged in, you may have a problem with power cord.
Then check for loose power connections, power losses or surges at power outlet. IF you still cannot resolve the problem,
contact your local dealer for assistance.
•If the LED indicators are normal and the connected cables are correct and the packets still cannot transmit, please check
your system's Ethernet devices' configuration or status.

Hardware Installation Selecting a Location

AT-IMC100T/SCSM and AT-IMC100T/SCMM Fast Ethernet Industrial Media Converters
6. Hardware Installation
6.1 Selecting a Location
Here are the guidelines for choosing a location for the media converter:
•The Fast Ethernet Industrial Media Converter may be installed on a wall or on DINRAIL.
Note: The DINRAIL bracket must be ordered separately from the AT-PC2002/POE+ media converter
Caution: The Fast Ethernet Industrial Media Converter must be powered only by a UL Listed power supply marked either
"LPS" (or Class 2) rated 56Vdc, 1A.
Caution: The Fast Ethernet Industrial Media Converter must NOT be operated from Centralized DC battery.
•The site should provide easy access to the ports on the front of the chassis so that you can easily connect and disconnect
the network cables, as well as view the unit’s LEDs.
•Air flow around the unit and through the side vents should not be unrestricted.
•Do not place objects on top of the chassis.
•Do not expose the device to moisture or water.
•Make sure that the site is in a dust-free environment.
•Use dedicated power circuits or power conditioners to supply reliable electrical power to the network devices
•Keep the media converter chassis and the twisted pair cable away from sources of electrical noise, such as radios, electric
motors, transmitters, broadband amplifiers, power lines, and fluorescent fixtures.
6.2 Installation Steps
6.2.1 Unpack the unit packing.
6.2.2 Check the DIN-rail clip is screwed on the unit. If the DIN-rail clip is not screwed on the unit, please refer to the DIN-
Rail Mounting section for DIN-rail installation. If you want to wall-mount the unit, then please refer to the Wall-Mount Plate
Fixing section.
6.2.3 To hang the unit on the DIN-rail track or wall, please refer to the Mounting Installation section.
6.2.4 Connect Ground Wire to the Ground screw located near the Power Socket.
