Mounting Dimensions
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back
panel of IMC when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to IMC, make sure the stiff metal spring is
situated towards the top, as shown in the figures below.

— 4 —
STEP 1:
Insert the top of the DIN-Rail into the
slot just below the stiff metal spring.
STEP 2:
The DIN-Rail attachment unit will
snap into place as shown below.
To remove MOXA Industrial Media Converter from the DIN-Rail, simply
reverse Steps 1 and 2 above.
Wall Mounting (OPTIONAL)
For some applications, you will find it convenient to mount MOXA
Industrial Media Converter on the wall, as illustrated below.
STEP 1:
Remove the aluminum DIN-Rail attachment plate from MOXA Industrial
Media Converter, and then attach the wall mount plates, as shown in
the diagrams below.
⇒
⇒⇒
⇒
STEP 2:
Mounting MOXA Industrial Media Converter on the
wall requires 4 screws. Use the IMC, with wall
mount plates attached, as a guide to mark the
correct locations of the 4 screws. The heads of the
screws should be less than 6.0 mm in diameter,
and the shafts should be less than 3.5 mm in
diameter, as shown in the figure at the right.
NOTE Test the screw head and shank size by
inserting the screw into one of the keyhole
shaped apertures of the Wall Mounting
Plates, before it is screwed into the wall.
Do not screw the screws in all the way—leave a
space of about 2 mm to allow room for sliding the
wall mount panel between the wall and the screws.

— 5 —
STEP 3: Once the screws are fixed in the wall, insert the four screw
heads through the large parts of the keyhole-shaped apertures,
and then slide MOXA Industrial Media Converter downwards,
as indicated below. Tighten the four screws for added stability.

Wiring Requirements
Warning
Do not disconnect modules or wires unless power has been
switched off or the area is known to be non hazardous.
The devices may only be connected to the supply voltage
shown on the type plate.
The devices are designed for operation with a safety
extra-low voltage. Thus, they may only be connected to the
supply voltage connections and to the signal contact with
the safety extra-low voltages (SELV) in compliance with
IEC950/ EN60950/ VDE0805.
Warning
Substitution of components may impair suitability for Class
I, Division 2 and Zone 2.
These devices must be supplied by a SELV source as
defined in the Low Voltage Directive 73/23/EEC and
93/68/EEC.

Safety First!
Be sure to disconnect the power cord before installing
and/or wiring your MOXA Industrial Media Converter.
Safety First!
Calculate the maximum possible current in each power wire
and common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring
could overheat, causing serious damage to your equipment.
You should also pay attention to the following points:
 Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring
in the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.
 You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of thumb is
that wiring that shares similar electrical characteristics can be
bundled together.
 Keep input wiring and output wiring separated.
 It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding MOXA Industrial Media
Converter
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Alarm Contact
The Alarm Contact consists of two middle contacts of the terminal block
on IMC’s top panel. You may refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector,
and how to attach the terminal block connector to the terminal block
receptor.
In this section, we will explain the meaning of the two contacts used to
connect the Alarm Contact.

— 7 —
FAULT: The two middle contacts of the
6-contact terminal block connector are used
to detect both power faults and port faults.
The two wires attached to the Fault contacts
form an open circuit when:
1. IMC has lost power from one of the DC
power inputs.
OR
2. One of the ports for which the
corresponding PORT ALARM Dip Switch
is set to ON is not properly connected.
If neither of these two conditions occurs, the
Fault circuit will be closed.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on IMC’s top panel are used for IMC’s two DC
inputs. Top and front views of one of the terminal block connectors are
shown here.
STEP 1: Insert the negative/positive DC
wires into the V-/V+ terminals.
STEP 2: To keep the DC wires from pulling
loose, use a small flat-blade screwdriver to
tighten the wire-clamp screws on the front of
the terminal block connector.
STEP 3: Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on IMC’s top
panel.
Before connecting IMC to the DC power inputs, make sure the
DC power source voltage is stable.

Communication Connections
IMC-101 models have one 10/100BaseT(X) Ethernet port, and one
100BaseFX (SC or ST type connector) fiber port.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on IMC’s front panel are used to
connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.
RJ45 (8-pin, MDI) Port Pinouts RJ45 (8-pin, MDI-X) Port Pinouts
RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring
RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
100BaseFX Ethernet Port Connection
The concept behind the SC port and cable is quite straightforward.
Suppose you are connecting devices I and II. Contrary to electrical
signals, optical signals do not require a circuit in order to transmit data.
Consequently, one of the optical lines is used to transmit data from
device I to device II, and the other optical line is used transmit data from
device II to device I, for full-duplex transmission.
All you need to remember is to connect the Tx (transmit) port of device I
to the Rx (receive) port of device II, and the Rx (receive) port of device I
to the Tx (transmit) port of device II. If you are making your own cable,
we suggest labeling the two sides of the same line with the same letter
(A-to-A and B-to-B, as shown below, or A1-to-A2 and B1-to-B2).

ST-Port Pinouts ST-Port to ST-Port Cable Wiring
This is Class 1 Laser/LED product. Do not stare into the Laser
Beam.
Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a
backup, and automatically supplies all of MOXA Industrial Media
Converter’s power needs.
Alarm Contact
MOXA Industrial Media Converter has one Alarm Contact located on
the top panel. For detailed instructions on how to connect the Alarm
Contact power wires to the two middle contacts of the 6-contact
terminal block connector, see the Wiring the Alarm Contact section
above. A typical scenario would be to connect the Fault circuit to a
warning light located in the control room. The light can be set up to
switch on when a fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for
connecting to an alarm system. The two wires attached to the Fault
contacts form an open circuit when (1) IMC has lost power from one of
the DC power inputs, or (2) one of the ports for which the corresponding
PORT ALARM Dip Switch is set to ON is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.

Dip Switch Setting
IMC-101 series DIP switch
Dip Switch 1 (Default: Off )
ON: Enables the PORT Alarm. If the port’s link fails, the
relay will form an open circuit and the fault LED will
light up.
Off: Disables the corresponding PORT Alarm. The relay
will form a closed circuit and the Fault LED will never
light up.
Dip Switch 2 (Default: ON )
ON: Enable full duplex for 100BaseFX
Off: Disables full duplex for 100BaseFX
Dip Switch 3
Reserved for future use
To activate the updated setting of dip switch, you need to power off then
power on the switch.
LED Indicators
The front panel of MOXA Industrial Media Converter contains several
LED indicators. The function of each LED is described in the table
below.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect MOXA Industrial
Media Converter’s 10/100BaseTX ports to any kind of Ethernet device,
without paying attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or cross-over cable to connect IMC to Ethernet devices.
Dual Speed Functionality and
Switching
MOXA Industrial Media Converter’s 10/100 Mbps RJ45 switched port
auto negotiates with the connected device for the fastest data
transmission rate supported by both devices. All models of MOXA
Industrial Media Converter are plug-and-play devices, so that software
configuration is not required at installation, or during maintenance. The
half/full duplex mode for the RJ45 switched ports is user dependent and
changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.
Auto-Negotiation and Speed Sensing
All of MOXA Industrial Media Converter’s RJ45 Ethernet ports
independently support auto-negotiation for transmission speed in the
10BaseT and 100BaseTX modes, with operation according to the IEEE
802.3u standard. This means that some nodes could be operating at 10
Mbps, while at the same time, other nodes are operating at 100 Mbps.
Auto-negotiation takes place when an RJ45 cable connection is made,
and then each time a LINK is enabled. MOXA Industrial Media
Converter advertises its capability for using either 10 Mbps or 100 Mbps
transmission speeds, with the device at the other end of the cable
expected to similarly advertise. Depending on what type of device is
connected, this will result in agreement to operate at a speed of either
10 Mbps or 100 Mbps.
If a MOXA Industrial Media Converter RJ45 Ethernet port is connected
to a non-negotiating device, it will default to 10 Mbps speed and
half-duplex mode, as required by the IEEE 802.3u standard.
