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.

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.
7
WARNING
This equipment has been evaluated as EEx nC IIC T4
equipment under DEMKO Certificate No. 03 ATEX
0324537U. Each module is marked with
II 3G and is
suitable for use in Zone 2 Explosive Atmospheres. Devices
must be installed in a minimum IP 54 enclosure as defined in
IEC 60529 and EN 60529.
ATTENTION
This unit is a built-in type. During installation into certain
end equipment, it must comply with fire enclosure
stipulations of IEC 60950/EN60950, or similar statements.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa Industrial Media Converter.
ATTENTION
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:
y 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.
y 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.
y Keep input wiring and output wiring separated.
y 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.

ATTENTION
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 is made up of the two middle contacts of the terminal block
on IMC’s top panel. 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 explain the meaning of the two contacts used to connect the
Alarm Contact.
FAULT
FAULT
Top View
Front View
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.
Top View
Front View
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.
ATTENTION
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.

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).

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.

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 advertise similarly. 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.
