Mounting Dimensions

(Unit = mm)

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

— 3 —

.

STEP 1:
Insert the top of the DIN-Rail into the

slot just below the stiff metal spring.

To remove MOXA Industrial Media Converter from the DIN-Rail, simply
reverse Steps 1 and 2 above.

STEP 2:
The DIN-Rail attachment unit will

snap into place as shown below.

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.

-- 4 --

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.

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 com pliance with
IEC950/ EN60950/ VDE0805.

Substitution of components may impair suitability for Class
I, Division 2 and Zone 2.
These devices must be supplied by a SELV source as

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 transm it t ed 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 interferenc e (EMI). Run the ground c onnection f rom the
ground screw to the grounding surface prior to connecting devic es.

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 mi ddl e contact s 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.

— 6 —

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 c abl es.

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 transmi t 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 f ull-dupl ex 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-t o-B2).

Beam.

Redundant Power Inputs

Both power inputs can be connected simultaneously t o live DC power
sources. If one power source fails, the other live sourc e 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 switc h, you need t o power off then
power on the switch.

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect MOXA Industrial
Media Converter
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.

’s 10/100BaseTX ports to any kind of Ethernet device,

Dual Speed Functionality and
Switching

MOXA Industrial Media Converter’s 10/100 Mbps RJ45 switched port
auto negotiates with the connected device for th e fast est dat a
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 install ation, 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 RJ 45 Ethernet ports
independently support auto-negotiation f or transmis si on 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 capabil ity for us i ng either 10 Mbps or 100 Mbps
transmission speeds, with the device at t he 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.
